I'm building the TF .60 P-47 and just finished with the rear deck and attaching the tail feathers. I took a look at the rear stab incidence and it looks by my highly calibrated eye ball that it's more than the +1 degrees the plans call for. It looks more like 2 or 3!! Sooo what will that do to the flying characteristics? I'm not 100% sure it's off that much or it may be more, but I don't have a meter to measure it with right now. I hate to have to tear this thing all apart now, I don't think I could really get the tail apart without some major damage. Any suggestions?

Thx, Nick

Nick, if the stab incidence is off, your elevator will carry trim in flight to fly straight and level. On a warbird like this, that's no worries. It will also slightly throw off the rudder-elevator coupling with rudder input. Again on a warbird like this, not something that would be a focal point for concern.

Thanks AnnMarie for taking the time to answer my question I really appreciate it. I feel better now.

camss69 - At the very least you should block up the plane and check the incidence of the stab, wing and the thrustline. At least you'll know for sure what you're dealing with. Sometimes things aren't what they appear to be. Your stab may be dead on.

amcross is right that if the number you posted is correct, then it's not cause for alarm. The problem is that trim settings will be speed sensitive. Usually I set up my dual rates to give me plenty of throw on high rate in case I don't have enough throw at the recommended rates. So far I haven't had a problem that I needed the high rate. I have had planes where I almost ran out of trim on a surface on the first flight.

Here's something else to think about. If you balance the plane slightly nose-heavy AND the stab has all that positive incidence you may need a lot of up trim. Don't sweat it, just be ready on the sticks. Get some altitude and get her trimmed. Land, make adjustments and have fun. :thumbup:

Well i went ahead and ripped the tail off, no matter how I measured I was at +3 degrees and closer to 3.5 or 4. I put that in G2 and flew it around on the giant scale p-47 and it took all the trim in my xmitter. Soooo I think all I'm going to need to completely rebuild the fin, it broke on the trailing edge. I will have to fully re-sheet the bottom of the stab, but with a little corrective sanding I should be able to get everything back together. Actually now that I think about it I may be able to get the fin back on as well. Anyway, why do it once when you can do it twice!!

Cams, If you need parts you can get them straight from top flite....

good luck with it!
