I will say I'm very excited to get this bird in the air after reading this thread. I'm a decent park flier and this is my first 3Der. Heck prior to this summer the last time I flew an RC plan 3D flying wasn't heard of.
You may want to seek additional advice, but one thought about the hinge issue is to cut the hinge completely through with a blade, butt the 2 pieces together and reapply welder to just the top side so the dried welder between the pieces becomes the hinge. The welder makes a strong hinge from my experience fixing hinge tears on a number of planes (EPP and EPO).

Welcome to the club and forum Doc.

Can't help you with the motor. But I can with the hinges, if you have some acetone handy it will soften up the hinges. It's how I do it, plus it's how I reuse parts when the airframe is shot.

I switched my motor/esc out with a working combo from another foamy, all is well. Weird thing is that it worked fine without a prop, once the prop was on it cogged or stuttered. I put it on another plane with a different/smaller propellor and it works just fine with the smaller prop.

Not sure what all this means but I will be ordering more batteries!

Also I have been using some 500mah batteries that are around 31grams, I have some two cell 1000mah batteries that weight in at 57grams but I wasn't sure whether the greater weight would kill the flying characteristics of the plane.

Wouldn't that destroy the graphics?

I do think the 250 is to small. The Rim fire 300 on 3 or maybe 2 cell lipo is a much better choice as I see it.

Thanks for pointing that out Stark. I should have mentioned apply the acetone to a rag and rub the inside hinge. It'll take some of the welders off and soften the hinge enough to work smoother. Working the hinge back and forth afterwards will help as well. The outside of the hinge is really the only place that could use the welders to help from tearing.

That is strange Matt. Maybe the prop not balanced could be the cause. What size prop were you using? Adding weight does effect the flying. More weight better windy day flying, less weight more floaty it flys.

I bought one of these just for the heck of it. Thought it might be worth a shot.

Sounds like your magnets may not be strong enough to swing the bigger prop. Have you ever gotten them very hot - they tend to demagnetize after a certain temp.

The heavier batteries will change the way the plane flies. The biplane can probably handle it in flight, but you will be carrying more inertia if you crash, and it will likely cause more damage than you normally would see.

I tested two motors right out of the box they are these:

I just think it is a stretch for the bigger props. I found a good replacement, I think, for the TH motor. It is at value hobby:

Should work fine and still be lightweight. I like the 300 size motors but most of the time you need to step up the size of your ESC. I think the added weight would kill the handling and cause more damage in a crash.

I love the 250 and will be installing one on my Crack Slick, not sure if it will have all the pullout power you might want with the Pitts. I flew this on a 6oz monoplane and it was blistic on 2S. If you dont need all the power in the world i wouldnot be afrade to try it. If you are used to Gobs of power i would look in to something else.

The revised motor just came in the mail. I think I am one of the last houses in the area to get the mail. Anyway...it's here. The prop fit a little loose without the prop saver on. I was thinking, oh no! But after the prop saver was put on, no slop was noticeable.
Will screw the motor on and have enough daylight to get in several flights. Woo-hoo!

That motor looks interesting Tom. Going try it out on your Pitts?

STLAV8R, I thought the prop saver was built into the can. Got any pics to clarify what you mean?

Me? If so the answer is no. I just saw it and thought it looked like a really strong other choice. I plan touse it on a wing I'm building. As for my TH planes I use the TH power combo only. Big fan here. But I should have the wing up and flying mid week with that motor.

If your looking for a cheap replacement motor till the TH motors come back in stock this looks pretty good. Not sure how it'll work out but for the price what the heck.

I did put the 250 on the pitts and it seems to fly it well but I don't have anything to compare it to. The problem I'm having now is balance. The tail is heavy even with the battery mounted all the way forward.
