okay i see what you mean now. Thanks Chuck!
I was a bit confused about a few things but now i see what your talking about. I'll stock up on a few diff variations on props till I get that sweet spot.
As for the pipe length i cant really do to much with that. My pipe clips directly onto my engine. So the guess work of pipes will be easy for me. I'll just have to experiment with props now. And get my DD completed! I'm really anxious to get it into the air now!
