Ron,

The question was "does it need a P200" to which I basically replied "I don't think it does". My opinion and I'm entitled/sticking to it mate!

As Morne/Skymaster say the model should not be powered by more than 16kg without modification.

I hope it stays together for you as it will be a blast flat out. I just know that I'd be modifying areas of mine before I put 50lbs of thrust in it - maybe you didn't see the same issues I did when you built your one??!!

Cheers,
Mark
