My Feedback: (2)

All,

Finalizing the setup on my P51B. This is an old redbox kit for .40 to .60 size engines. I'm coming it at about 7lbs, with about 28oz/sq in of wing loading, using a OS .61FX to power the beast.

Plans call for 40 degrees of flaps - that sounds like a bunch, and would require some down elevator to be mixed in IMHO.

Anyone with experience on this kit that could provide some advice?

Thanks,

My Red Box P-51 is still sitting in the box. Forty degrees of flaps doesn't sound out of line with other aircraft. If you're concerned about pitch trim changes, you can go conservative and mis in only 25 degrees or so and gradually add more ass you become more familiar and comfortable with it's flight characteristics. If you have a computer radio, I do recommend mixing the pitch trim change out. At 7 lbs, it should be a great flying airplane.

Good luck,

Rob

I had a Red Box TF P-51B for some years ('til the switch harness packed up mid air!!)

I used at least 40 degree of flap and never really noticed any pitch change, I never mixed in and elevator.

Sticking out the flaps slowed it down very quickly, so keep some power on all the way down.
