Build-Along — Sopwith Camel — Update: Engine and Fuel System Check

If we have been following along with this extended Workshop Build-Along series, we know that from a start, we designed a Sopwith Camel around a Zenoah G38 gasoline engine. One of a good advantages of blemish building, is that we can from a start examination all so we can use a engines and apparatus we wish too though carrying to “re-engineer” things. All your tools fit.

(Above) here’s a territory of my skeleton display a engine, firewall and a fuel tank positioning.

If has been about 16 months from a time we started a CAD drawings for a devise and final weekend we achieved one of a some-more critical tasks concerned in a new aeroplane project–that being exam regulating a engine. we have schooled from experience, that it is not a good thought to wait compartment we are during a drifting field, (with all your bar buddies around), to try and setup and adjust a engine.

(Above) Here’s my aged arguable G38. It is some-more than 15 years aged and is a comparison magneto versed type.

In a array area or a commander hire during a margin is not a time to rush things. So, my procession is always to accumulate all a apparatus that we devise to use in a indication and arrange it on a exam rig. So for a Camel, this involves ascent a engine and scarf on a suitable structure and afterwards setup a fuel tanks and any other tools like a stifle linkage and fuel line fittings.

I also motionless to use a new RotoFlow Fuel System from JL energy Products. This is an wholly new fuel tank judgment and after regulating a tanks in several models, I have found them super easy to implement and really reliable. They are also totally upkeep free, that is good for a idle man like me. As we can see, we done support brackets to support a tank inside my model.

(Above) As we can see here, we have transposed a strange carb. with a larger, stifle versed one from a Quadra 50 engine.

For my exam run, we simply upheld a servo finish of a stifle linkage with a rubberband so we could adjust a stifle settings and set a linkage length for what ever energy environment we wanted. Usually we also implement a stifle servo and control a engine with my conductor and airborne radio gear. we make a exam box from complicated hunger play and screw them together with heavy-duty screws. we also screw a box structure to a secure bottom like this 2×10 house that is also screwed to a sawhorses.  Do not screw your exam supply to your wife’s cruise table!

I was really gratified to find that a G38 dismissed right adult though any issues and we usually had to tweak a low-end needle valve a smidgen for a good arguable idle and well-spoken transition to full power. Just a approach we like it! Whenever we can, we like to use an electric started (Sullivan DynaTron), when contrast engines. Once a engine has warned adult for a few minutes, a stifle response is really good. we also commissioned a Zenoah quickness smoke-stack though this is some-more for only containing unburned gas that gets siphoned out of a carb from a airflow, and reduction about augmenting atmosphere intake.

Of course, we should always check all a engine bolts and screws to make certain they are parsimonious and safeguard that your propellers are scrupulously balanced. we use Xoar and Falcon Propellers so this is frequency and issue, these props come out of a package offset and prepared to shaft into place.

Hope these tips assistance we be successful with your initial exam flights.

Fly safe!
