Here is a complete, unedited content from Pat Tritle’s many new project.

The Royal Aircraft Factory S.E.5a was initial flown in Nov of 1916, and entered use in Jan 1917 after modifications to strengthen a wings were finished to a third proto form to scold for weaknesses detected in initial moody testing. The S.E.5 valid to be a really fast platform, and by squaring a wings a bit over a initial pattern also softened low speed handling. The S.E.5a was a improved aeroplane afterwards a Sopwith Camel and fast valid itself to be easier to fly, generally by beginner pilots.

The S.E.5a had most improved opening afterwards a Camel as well, yet was tormented with problems from a under-developed Hispano-Suiza engine, generally a geared H-S 8B powered versions that combined a necessity of S.E.5a’s until good into 1918. However, together with a Camel, a S.E.5a was instrumental in progressing atmosphere supremacy in midst 1917 and by a rest of a war.

The S.E.5 had a wingspan of 26 feet 7-inches and was 20 feet 11-inches long. Empty weight was 1,410 lb. with a sum weight 1,988 lb. Power was supposing by possibly a Hispano-Suiza 8 or a Wolseley Viper 200 HP engine with a limit speed of 138 mph, a operation of 300 miles, and a use roof of 17,000 ft.

Armament enclosed a Vickers .303 distance brazen banishment appurtenance gun banishment by a column with a Constantinesco interupter gear, and a Lewis .303 distance appurtenance gun blending to a Foster mountain on a tip wing.  The S.E.5 could also cary 4, 25 lb. Cooper bombs, 2 on any reduce wing. Though not as maneuverable as a Camel, a S.E.5 valid itself a good fast height with glorious high altitude opening visibilty and was a estimable competition opposite a Fokker D-VII on a attainment during a front, yet it was felt that in annoy of a strength and excellent drifting qualities was a bit under-powered until it began to be transposed with a S.E.5a in 1918 until a finish of a war, eventually equipping 21 British Empire Squadrons and 2, U. S. Units.

The Model

 The S.E.5 is usually about a ideal height for a tiny – mid-sized electric powered park flyer. With a prolonged nose, generouse dihedral, and inherently fast drifting qualities, it creates for a superb initial WW-I fighter. And with a elementary all timber pattern incorporating loyal lines with few formidable curves lends itself good to a beginner builder as well.

  The fuselage and tail organisation are of a customary aged propagandize “stick frame” character of construction, while a wings are finished in a some-more complicated “egg-crate” character to speed adult and severely facilitate a building procees and discharge unecessary structure. And by regulating a elementary centerline tip wing fixing hop and reduce wing tip jigs finished adult from artists froth house wing fixing is elementary and usually about bone-head proof. The indication also incorperates organic scale paraphernalia that aids in gripping a weight down that is what creates a S.E.5 such a gentle, yet really able flyer.

The indication is set adult for 400 Outrunner energy on 2 LiPoly cells and is tranquil with 4 channel R/C regulating one servo any for a rudder and elevator, and a servo in any reduce wing to control a bottom wing ailerons. The tip wing ailerons are slaved to a bottom regulating a elementary integrate rod arrangement.

Building a S.E.5a

 Before construction begins, accumulate adult a materials called out on a tools list, afterwards cut out all a tools regulating a full distance patterns provided. The templates can be laid over a timber sheets and cut by a patterns, or we can make printwood from a drawings provided. Once all a tools are cut out, construction can get underway.

Tail Section:

Begin with a loyal and plane tails. Lay out a assemblies over a skeleton regulating a partial numbers and timber sizes shown. Once a elementary public is completed, mislay a tools from a house and silt to shape. Cut a hinge slots and dry fit a hinges, yet don’t glue them in place until after a tools are covered. The hinges are 5/32 x 1/2-inch strips cut from Great Plains hinge stock. The rudder control horn is finished from a turn wooded toothpick cut to 1 1/4” long, centered in a rudder, yet don’t glue it in until a frames have been covered.

Top Wing:

Starting with a tip wing, pin A8, A12, and A13 in place on a plans. Then dry fit a ribs R4, R5, R6 onto a categorical punch A2T and pin a public in place over a plan. Fit a aileron hinge punch A4T in place and afterwards hook glue any indicate of hit with a dump of skinny Cya. Next, regulating a Rib Angle Gauge, align and glue rib R3 in place, followed by a heading and trailing edges. Build adult a wing tips from 1/8-inch sq. balsa and tools A2 A3 regulating a public sketch provided. Align a tip public with a categorical and aileron hinge spars and glue A2 in place opposite a heading edge, and A3 to a trailing edge.

Build a ailerons in place into a wing assembly. Begin by sanding a shelf into a bottom of A5 regulating a rib fact drawings for reference. Pin A5 in place and supplement a ribs AR1 AR2, followed by A10 glued in flush with a bottom of a aileron. After both wings are completed, build adult a Center Section directly over a plans. With a elementary public completed, fit a wing panels in place and retard them adult 1.2-inches during a plcae shown. Glue a panels in place followed by a 4, A9 cabane strut doublers on A8. Now we can mislay a wing public from a house and silt to shape. Once a wing is sanded to severe shape, cut a ailerons giveaway and finish fact sanding a whole assembly. Cut in a hinges, yet don’t glue them in until after a wing is covered.

Bottom Wing:

The bottom wings build most like a top, with a disproportion of a servo mounts and a plcae of a interplane strut ascent points. Begin by pinning a SM1 servo mountain image and a categorical punch A1B in place on a plans. Glue R5A in place on R7 creation a RH and a LH assembly, afterwards trip ribs R4, R6, R7, and R9 in place on a spar, followed by a aileron punch A4B. Pin a 1/16 X 1/4-inch balsa trailing dilemma in place and hook glue any indicate of contact. Then relocating toward a root, glue a R8A doublers in place on a R8 ribs as shown – you’ll need to make a RH and a LH assembly. Pin a behind support A16 over a plans, afterwards regulating a Rib Angle Gauge, align and glue a R8 rib in place followed by A-17. Then relocating behind to a tip, build adult a tip assembly. Align and glue a 1/4 X 3/8-inch balsa heading dilemma in place, followed by a tip assembly. And finally, cut a fixing dowels to length and glue them into a R8 ribs.

Next, align and glue a interplane strut tough points A14 and A15, and a servo mountain braces SM2 and SM3 in place. Assemble a ailerons on a wing public a same as was finished building a tip wing, a usually disproportion being A11 that is glued in flush with a tip surface, and A6, glued flush with a bottom. Then once a glue has dried, mislay a wing public from a house and silt to shape, Remove a aileron and finish fact sanding a parts, and finaly, cut in and dry fit a aileron hinges.


Begin by pinning B1, B4, and B5 in place over a Fuselage Frame Assembly drawing. Then supplement all of a remaining framing regulating a timber sizes shown. Build 2 frames, adding a lift rod beam PRG flush with a outward dilemma of a RH support assembly. Align and glue B2 and B3 in place during a locations shown, again being certain we have a LH and a RH side. Build adult a cabane strut mounts from tools CM1 and CM2 and set them aside until later.

Before fasten a frames, make adult a alighting paraphernalia mountain beams as shown per a Detail Drawing. Pin a beams to a Framing Plan Top/Bottom View with a nick confronting down. kindly moment a longerons during Former Station 3 so that a sides angle central toward a tail and afterwards fit a fuselage sides over a beams. Align a sides plumb and glue in place on a LG beams. Build adult a engine mountain and former 1 and glue a public together, afterwards glue in place onto a a front finish of a fuselage frame. Add a 1/8-inch Sq. balsa crosspiece as shown usually in front of B2. Add formers 2 and 3, a Cabane Strut mountain assemblies, and a 1/16 X 1/8-inch balsa cranky square next former 3. Pull a tail post together, align and glue it in place followed by formers 4, 5, 6, and 7 and all of a remaining cranky pieces, followed by all of a 3/32 Sq. balsa stringers to finish a elementary fuselage frame.

Build adult tail movement and radiator assemblies regulating a partial numbers shown. Make adult a cover flaps from 1/16 X 1/8 balsa sanded to a triagular cranky section. Glue all of a louvers in place as shown and fit a cover public onto a fuselage and silt to final shape.

Setting Up a Servos:

Align a servo arms to a neutral position and glue a aileron servos onto a mountain plates SM1 regulating silicone caulk and set aside to dry thoroughly. When dry, run in a prolongation leads. Then relocating on to a fuselage, glue a servo mountain rails and beams in place regulating a timber sizes shown. Mount a servos with a rudder servo on a centerline, and a conveyor servo to a distant RH side. Run in a Sullivan #507 cosmetic conveyor pushrod tube and secure it on both ends and during a integrate of points in between regulating a PRSO stand-off’s. Rig a continual rudder pull/pull cables per a Detail Drawing provided. Tape a rudder public in place on a fuselage and tie a cables off during a control horn. Mark a accurate plcae on a skeleton where a cables exit a fuselage for anxiety to be used after a indication is covered.

Making Up a Wire Parts:

Patterns are supposing for tortuous a Landing Gear and Cabane Stut components as good as a public sketch to build adult a Landing Gear Spreader that offers some cessation in place of a firm alighting gear.

Begin by tortuous all of a alighting paraphernalia components to figure regulating a supposing patterns from a hoop sizes shown. Tape a struts in place on a fuselage support and solder a front and behind struts together. Slip a brief territory of a spreader hoop into a coronet tube and solder it in place. Then trip a prolonged territory into a tube and solder a public in place on a gear. Be clever not to inadvertently solder a prolonged hoop into a tube or a trip dilemma won’t work and you’ll finish adult with a firm paraphernalia after all. Then after all a joints are soldered, hang all of a junctions with excellent copper hoop and re-solder all a joints. Now we can supplement a Fairings LGF and LGR, and afterwards mislay a Landing Gear Assembly from a Fuselage and set it aside until Final Assembly.

Bend a Front Cabane Struts per a Bending Patterns and set aside. For a behind Cabanes, make usually a bottom bent, afterwards trip all 4 struts into a mounts and position them as shown on a fuselage side view. Now that we can daydream a devalue angle during a tip of a behind struts, make a bends so that a struts expel plumb upwards so that a bends during a tip of all 4 struts are together and perpendicular.

Mounting a Motor:

The firewall is set adult for possibly a Suppo 2212 or a E-flight Park 400 Outrunner motor. Mount a engine with during slightest 2 screws, afterwards set adult a ESC and exam a engine (without a propeller) to check for correct instruction of rotation.

Covering a S.E.5a:

The indication should lonesome with a light weight iron-on film such as Coverite Microlite, Coverlite, or Nelson Litefilm. Light Silkspan or Tissue and bone-head are also a good option. we lonesome my indication with Dark Green Microlite on tip and Cream on a bottom, afterwards embellished a tip with Testors Model Master Field Drab finish regulating a Paashe H-1 Airbrush. To prep for paint, we wiped down a whole aspect with common White vinager to mislay a excess left by a manufactering process. Once it’s spotless up, hoop it as tiny as probable so’s not to leave greasy fingerprints that will outcome a already extrinsic paint adhesion.

To begin, cover all of a frames, except, for a bottom of a fuselage. We’ll get to that in a minute. For best results, always follow a manufacturers instructions for your selected material. Graphics for a S.E.5a are accessible from in usually about any intrigue we can find. Once covered, all of a hinges can be glued in place regulating Canopy 560 glue.

Final Assembly:

We’ll mountain a bottom wing first, and all else will align from there. To get started, cut a Bottom Wingtip Jigs and Top Wing Incidence Jig from artists froth house or plain corrogated cardboard. Feed a servo leads by a holes in a fuselage sides and retard a bottom wings into a fuselage. Locate a fuselage prosaic on a building house and afterwards support a wings with a jigs placed underneath a outer-most ribs. Glue a wings in place with Canopy 560 glue and concede to dry thoroughly.

Slip a cabane struts into their sold mounts, afterwards trip a tip wing onto a struts upheld by a Top Wing Incidence Jig. Then retard in a Interplane struts into a tip and reduce wings. With a wings good and straight, hook glue any indicate of hit with a dump of skinny Cya. Then lift a indication from a house and henceforth glue any of a strut loacations.

Now we can mountain a alighting gear, lash it in place with complicated avocation sewing thread and glue a dilemma gussets in place. Before a fuselage bottom is covered, strengthen a exit points for a rudder cables with a tiny square of Scotch pure tape. Align and glue a loyal and plane stabilizers in place and afterwards run in a rudder cables. Once they’re tied off and adjusted, cover a bottom of a fuselage and paint as required. The conveyor is connected regulating .025-inch hole steel wire. It can be connected with possibly a Z-bend during both ends, or regulating a Z-Bend during a behind and a Micro EZ-Connector during a servo.

To set adult a ailerons, initial set a servos arms to a neutral position. Make adult a pushrods regulating .032 hoop with a Z-bend during both ends. Slip a rod into a servo arm, afterwards place a control horn onto a rod and trip it into a container in a aileron. Align and glue a control horn in place. Then regulating The Aileron Link Rod fact drawing, cut 4 pieces of 1/16-inch O. D. aluminum tube, align and glue those sections into A10 and A11 regulating a territory of .032 steel hoop to keep them in line. Remove a steel fixing wire, and with a ailerons in a neutral position, cut a territory of tubing to fit between a tip and reduce pins, withdrawal a slight opening between any territory of tubing, put a square of feverishness cringe tubing during a tip and bottom to secure a integrate rod in place. The final step is to supply a wings and tail territory regulating complicated avocation nylon thread. The best approach to set adult a paraphernalia is to demeanour during cinema provided, or of a full scale S.E.5a and supplement as most of a scale paraphernalia as desired.

At this indicate a indication is flattering good complete, lacking usually a finer details. Mount a wheels, battery induce cover, cover and tail movement assemblies, afterwards supplement any other preferred details. The S.E.5a carried several opposite gun configurations from a Vickers appurtenance gun on a cover or a Lewis gun on a tip wing, and infrequently both. We’ll leave that adult to a builder regulating a scale gun drawings provided. And with that, your new S.E.5a is usually about prepared for it’s initial fight mission.

Balancing and Flying:

Balance a indication during a plcae shown regulating battery chain to your best advantage to accommodate CG. Using a 1320 2S Sky Lipo, a battery finished adult trustworthy to a behind side of a engine mount, cumulative with a Hook Loop strip. The contols were set adult to a values called out on a skeleton and double checked for correct instruction of deflection to finish a project.

Pick a ease still day for a trim flights – it’s tough to trim a new indication in severe air. With a indication forked into a breeze, make one final control check, and if all is OK, lift a stifle adult for a initial take-off. Ground doing is exceptional, even for a WWI form model, and once in a atmosphere it won’t take prolonged to see what a peaceful and pliable flyer a indication is. Control is frail and comparatively quick, yet a S.E.5a in not twitchy. The ailerons do vaunt a bit of inauspicious yaw, so a hold of rudder submit will repair that right up. And since of a inexhaustible scale dihedral, a indication turns equally as good with a rudder alone as with a ailerons.

Landing need that we lift a bit of power. Set adult a gentle penetrate rate regulating a conveyor to set adult a opinion rather nose high, afterwards use energy to control a rate of sink. Once in belligerent effect, a penetrate rate eases adult a good bit, and when a mains hold down simply lift a energy behind and she’ll stay on a belligerent though any bent to rebound behind into a air. Then once you’re gentle with how she flies, try a few scale maneuvers, and maybe even a few touch-n-go’s. From here, a usually thing left is to suffer a ride.
