G'day 1540!

I have a 1/3 scale Christen Eagle - which is basically a Pitts... I have a DA 50 R mounted in it from the previous owner. I was told that if I flew in a strait line with FULL POWER - I would tear the wings off!

So throttle management is a big deal. On the other hand, with that much power you can do anything that you want aerobatically with unlimited vertical - sort of depends how you plan on flying.

As to the vibration, the planes are designed for it as long as you keep the wings on. (no joke!) If you try to tune the engine without the wings on you will get a lot of vibration damage. The wings work to dampen the vibrations.

IF you go with the gas / petrol engine you will get about 30 minutes of flight time to a tank of fuel. With the nitro engine perhaps 10 minutes and nitro fuel is 3-4 times the price of petrol.

Finally; when you tire with the Pitts you will have a GREAT engine to install in that 1/4 scale Extra or CAP.

Happy Landings!
