Gee, sounds like I wrote this post!<div>
</div><div>The battery fix I found a simple solution to, get a couple Blade mCPx packs, and notch out the battery area on the plane. You get more flight time, and the CG is much better.  I too had to swap out the prop, had exactly the same issues you described.  I used a Sukhoi prop on mine, and it flies great, just watch those landings, the wings and tail are much more liable to crack  than the ones on the T-28. I need a new tail for mine and the wing is due to be replaced.  My T-28 however has at least 60 flights on it and it looks like it went through a war as a target.  </div><div>
</div><div>The nose is munched, the prop shaft is bent, the wings have wrinkles, the paint is all chipped off, the fin is held on with tape, but it still flies great. </div>
