Yellow P-40 flight characteristics
Well guys, I am new to warbirds and have a Yellow AC P-40 just about ready to test fly. My gyro for the rudder failed right out of the box and is enroute to the repair station, once it is returned I have about an hour worth of work to be ready for the testflight. Can you YA P-40 jocks give me any heads up on what to expect. Been flying turbines for many years and havent flown a prop much less a tail dragger for a long time. Thanks

RE: Yellow P-40 flight characteristics
hello it pretty much depends on what surface you're taking off from grass you will need to keep up elevator until you reach inappropriate texting speed depending on what size prop engine u will have to counter the torque with some right rudder. to avoid loss of control. and make shallow take off to avoid tip stall
do not try to land this plan without flaps

RE: Yellow P-40 flight characteristics
A lot depends on weight and what engine you have. Mine weighed 27lbs and has DA50 with 22x8 prop. Lots of power and flies 1/2 throttle or less.
All throws and CG as per manual. Wing is in two halves with wing tube joiner for ease of transport.
Main points are rudder can be sensitive on takeoffwith narrow track U/C so watch your movements and add some expo.Make sure tail comes up before trying to lift off and do not climb too steep. Once in the air tracks really well and positive. If you have flown turbines you should not find this any harder to fly. Flaps help landing a lot (I found at least 30 degrees and 40 if you can get it) but do not slow down too much, fly slow andit will drop faster than you would like. On mine gear and flaps position affected trim so be prepared for this until you establish if you need to add mixing. In general mine perfomed and flew better than I expected and hopefully you will find the same, best of luck with maiden.
A great model with good access to the engine, very sturdy construction and strong retarcts, no need for any weight in the nose if you place everything right for balance.

RE: Yellow P-40 flight characteristics
If anyone out there has an unassembled kit of the Yellow P-40 and would be willing to trace the root airfoil for me I would be very greatful. Heck, I'd even be willing to pay a modest fee for the job. I have been asked to design a wood wing for the airplane but need to know what airfoil was used in order to be certain the wing will fit the saddle of the fiberglass fuselage. Any help much appreciated.
