To add to MinnFlyers comments I have just started flying a 1/4 scale Cap 232 with an Evolution GT35 engine. Some of the things I have learned thus far.

1) Do not run your ignition wires near the exhaust. They will work their way to the exhaust subsequently melt and your engine won't run. I spent about 2 hours flipping this thing over untill I found what I did.

2) Do not run your fuel line next to the exhaust. See comment one. I got to deadstick this 15 lb brick and fortunately will be able to replace/reroute the fuel line and try this again.

3) The exhaust muffler gets very hot. Hotter than any glow powered engine.

4) I use a good quality 2 stroke oil to mix with the unleaded gasoline (petrol) and carefully mix to the recomended proportions given by the engine manufacturer. In my case that is 40:1

5) Big wood props look cool It was recomended to me by fellow club members to use a wood prop on my gasser as you want the prop to break instead of the crank shaft on the engine... even at $23 a prop that's just insurance.

6) There is always more to learn
