giantscaleplanes (GSP) P-40 Warhawk
 

I recently assembled the giantscaleplanes P-40 Warhawk ARF. I considered myself to be an intermediate flyer (proficient with .40 size up to 1/4 scale aerobatic models), however I had a time trying to fly this model.

I set it up as per the manual and had a very gentle setup as far as control surface throws and the center of gravity placement.

1. My first problem was that the model continued to want to nose over on the ground.
2. Once in flight, the model was very snappy, more so than the average warbird.
3. Upon Landing, it would snap out violently, therefore, I had to come in hot all the time. Once I got the P-40 on the ground, it would nose over.

Any suggestions on the giantscaleplanes .40 size P-40 fiberglassed model airplane. Please forward your comments to my email: [email protected]. Thanks!

snappy, check the wing washout sounds like it is wrong , if so move both elevators in very slight up when the sticks are in neutral , aslo make sure it balances from left and right as well as front and back

Snappy is an indication of an AFT CG. I would suggest you recheck that first. If it seems ok.. make it a little nose heavy.
Nosing over is more a position of the gear than any thing else. Some planes like the Spit and P40 are more prone that some others. There are a few things u can do to help. Make absolutely sure you wheels turn freely. You can also shim the rear of the retract to move the wheel hub a little more foward. Don't forget the Full Up elevator on the ground at all times. Hope this helps BobH.

Bob , i am not disagreeing but why full up at all times on the ground, I thought it was better to let this plane gain speed and let the tail lift gradually , or do you use full up let the tail come up them lighten up in the up ? I have read numerous post on the Tflight P40 and many pilots say that they dont force it in the air ?

Check this out for an example of holding the elevator too long.[link=http://www.rcuniverse.com/forum/m_354466/mpage_5/key_/tm.htm]Wildcat[/link]

I don't think BobH meant for you to hold full up during the takeoff roll, just during taxiing.

I find that putting a little up trim in the elevator when setting up for landing helps keep the plane from tipping over when it touches down. This helped on my Spitfire which always nosed over.

I agree but "full up at all times while on the ground" can be misunderstood as "full up on the ground at all times" , see hat I mean
