park zone corsair build questions

[flying dad]

hey everyone...........question for you experienced folks. I built a PZ f4u Corsair using electronics and from Aprentice and a eflite power 15 with a 40 amp esc. I added weight to the back to compensate for the extra weight and it balances out perfectly. Problem is it seems to want to dive constantly and is slow to climb in level flight. Do i just need more elevator? Am I just flying a new plane to slow out of caution? Anyone with simular circustances that could through some advice my way?

Prop? Did you check what amp draw you are getting with current set up. Maybe you need to prop up.

I put a larger 3 blade 10.5x8 off the bf109 I have the same setup in my t28 and that flys like its on rails.

the corsair just seems to fly nose heavy. Im just getting back in to RC after some time and alot has changed. The t28 with the same upgrades fly as it did stock, except a whole lot faster. the corsair just seems a bit slow to loop and climb unless at full throtle turns on a dime when banked

balance the model where the manual indicates. The manual says 62-64mm behind the leading edge of the wing at the wing root.

Being slow to climb would not except in very extreme cases be a sign of nose heaviness. Perhaps you have made the model overweight? When anyone says 'I added a heavier motor and so i added tail weight to balance' I think 'overweight model'. What does it weigh? Is the landing speed unusually high?

Or maybe you just need to fly faster, are you using full throttle?

I am beginning to think, as I expected, that I am being a bit over cautious and flying to slow. I have been flying my T28 for some time now and am more comfotable with the flight characteristics. Made the same modifications i.e. power 15, 40 amp esc , larger prop and 2 oz counter balance, and the plane air craft flys great. I think I just need to be as confident with the Corsair and "kick her in the tail" a bit and increase flying speed. Thanks for the input and I'll keep you posted. If any one has more advice my ears are open. Side note: as I am sure most of you more experienced pilots know, T28 with 15 size motor.....AWESOME

Have you checked the ESC settings? Some actually need to be set to the full throttle setting. It could cause you to reach full throttle too early, or maybe not at all.
