RC Scale Model Me 163 Komet Warbird Electric Powered with Rocket Performance

When we wish to wow them with an RC scale indication warbird, we can’t get any hotter than a Me 163 Komet. This electric powered chronicle has loyal rocket craft performance. First encountered by U.S. Army Air Corps bombers in Jul 1944, a modernized speed and maneuverability of a Luftwaffe’s new Messerschmitt Me 163 rocket craft took a Allied moody crews by finish surprise. Its accountability was carrying unequivocally brief powered flight, so a Komet was used essentially to urge German airfields and other vital targets. Allied escort/fighter pilots shortly beheld a singular powered moody generation and so waited for them to empty their diesel supply before enchanting a unpowered Komet in combat.

Other strategy used opposite a Komets were to follow them home and afterwards torpedo them after they had landed. Though good modernized of most– if not all — propeller-driven fighters of a day, a Me 163 Komet was a primary instance of “too tiny too late” as a pattern did tiny to change a outcome of a atmosphere fight over Europe.

I built my initial scale Komet around a mid-1990s from Jim Kiehl plans. It was 1:4.5-scale, had customary balsa and plywood construction and enclosed a fiberglass nose cone and transparent canopy we purchased from Joe Saitta. Spanning 82 inches, a Komet was a one-piece pattern and did not have removable wing panels. we powered it with a SuperTigre .90 heat engine and we was vacant by a opening and moody envelope.

In 1997, we was respected to accommodate Rudy Opitz (one of a strange WW II Luftwaffe exam pilots concerned in a Me 163 Komet program). Rudy met with us during a indication aeroplane eventuality in Stratford, CT, as he lived nearby. We all had a good time listening to Rudy re-live his practice during a controls of a Komet. Rudy was anxious to watch my indication Komet fly and was unequivocally happy to supplement his designation to it.

Fast-forward to only a few years ago and we built another Komet, this time regulating a fiberglass fuselage (also from Joe Saitta) and removable wing panels for easier transportation. This time, however, we chose a most cleaner electric energy complement for a Komet. The electric engine fits simply in a nose cone and is not during all visible, giving a some-more scale coming to a model. we quick realized, howver, that converting a pattern from heat to electric was not as easy as we had initial thought.

Power and Radio System

I wanted to spin a smallest diameter, top representation propeller during aloft rpm for dual reasons: singular column clearway and increasing speed. The immeasurable infancy of a incomparable outrunner electric motors have low Kv ratings, that means they have some-more winds of thinner handle and will lift some-more volts during low amps to furnish aloft torque while overhanging a bigger prop. we indispensable something with a aloft Kv rating. So with some assistance from a integrate of unequivocally associating electric gurus, we commissioned a Hacker A50-10L Turnado brushless engine with a Kv rating of 580. we joined this with a Castle Creations Phoenix Edge HV 160-amp, high-voltage speed control and a 12 x 13 APC propeller. The “fuel” we chose was dual Turnigy 4S, 5000mAh, Nano-Tech LiPo packs connected in series.

The energy complement was unequivocally easy to implement and isn’t “rocket science” (pardon my pun). The fuselage is cavernous and there was copiousness of room for me to implement a prolonged shelf to support a battery packs. This setup authorised me to slip a battery packs front and abaft to make adjusts to a core of gravity. The dual packs and speed control are hold in place with some unequivocally assertive Velcro straps. we vented outward atmosphere by a gun holes and a tiny cover opening by a fuselage and out a vast rocket empty entrance in a tail. The radio rigging in a fuselage includes a rudder servo, a receiver, receiver switch and a 1200mAh Ni-Cd receiver battery pack, that sits orderly behind a LiPo packs.

Flying Wing Design

The aeroplane is unequivocally only a elementary 4-channel RC indication with a wing’s control surfaces automatic with elevon control. There are dual moveable surfaces on any wing row and we use both handling in tandem. The takeoff barrow was done from 1/4-inch song handle focussed to figure and encapsulated in timber to demeanour identical to a genuine McCoy. The tires are from an aged baby carriage. There are dual song handle pins extending from a barrow that slip adult into relating coronet tubes built into a swell of a fuselage. The indication taxis out on a barrow and when a aircraft rotates for takeoff, a barrow falls away.

Electric vs. Glow Power

When it comes to comparing my electric Komet to a comparison heat version, we can contend is: Wow! The indication can simply stand out of steer from takeoff and it is impossibly fast. It is also unequivocally maneuverable and can out spin any other WWII epoch warbird. This is by no means a warn as a Me 163 was a fastest aircraft of a Second World War.

 

Flight Performance

As with all electric-powered models, a pivotal to prolonged moody generation is stifle management. The some-more stifle we use, a shorter your moody time will be, and this is really loyal with a Komet. we uploaded a moody information logs from a speed control and see that during full stifle a Komet pulls as most as 130 amps. At that rate it can empty those dual 4S packs in no time. However, a Me 163 is a unequivocally surprising aircraft. Designed by Alexander Lippisch, a Komet pattern came from years of glider investigate and a final aircraft pattern had higher gliding capability. Just like a full size, a indication also has well-developed slip performance. After a integrate of high-speed passes, we customarily move a indication adult to altitude and only stifle behind to 0 power. After 30 seconds or so, we supplement energy and repeat a process. Often half of my moody will be but any energy during all.

For landing, we cut power, drain off some additional speed and afterwards make a unequivocally prolonged approach. It’s a lot of fun perplexing to sign a speed and rate of skirmish only right so that a indication touches down uniformly and skids to a stop during a core of a field.

Bottom Line

My takeaway for this story is, if we don’t know what you’re doing, ask someone who does. The Me 163 has vastly softened moody opening and speed with a acclimatisation from heat to electric power, and we would like to give a lot of credit for a success of a Komet plan to my friends Greg Gimlick and Greg Covey who assisted me. They are both obvious and well-regarded electric energy experts.
