Default Balancing the H9 Cap232

Never have put in a pic. Don't know if this will work. I usually balance my planes more than slightly nose down, like about 30 to 40 degrees, but this plane really came out SLIGHTLY nose down. The fact that it is quite sensative in the air, I wanted to show the balance I now have with a Saito .72 up front and the battery under the servo tray. Do I need more weight up front, or is this acceptable for proper performance of the Hanger 9 Cap232 (40size)?

Finally, this is the way the plane balanced. . . . .

The balance looks good. I'm sure you have the gauge set to the balance point that hanger 9 suggests. Did you have to add any ballast to the plane other than the radio equipment?

No ballast needed, Bobby. CG is 4.75" back from the leading edge, suggested by H9. Probably the Saito .72 helped to balance. My first balance set-up had the battery right behind the fuel tank, thinking I needed forward weight, and oddly I had test run the engine, and could not get all the fuel out of the tank. It balanced at that time about 30 degrees nose down. So I figured that with tank empty, it would be where I wanted it. (I had put my third line in the tank without a klunk and have now pulled the cowl and attached a klunk to the feed line.) As you see it now, it is with empty tank and the battery is shoved under the servo tray as far aft as I can get it. Have not flown it in this mode, which is why I posted the pic. It did fly straight and level after a couple clicks of down trim were added. Why, I don't know.
This is a rugged plane. On my second time out to the field, I don't know if you have ever done it, but I was focused on my approach attitude and was wide, landed in the high grass and watched it cartroll. I knew I'd have a broken prop, severed wing bolts and canopy shattered. . . . .No damage!! Everything in tact.
Somebody's looking out for me. Brought it back and refueled for another flight....no matter what we did it would not start. We decided the klunk likely locked forward and would not feed fuel. Shook the plane violently nose-up, and the internal racket was unreal. Now I pulled the wing and was happy it would not start.
The receiver had broken loose from the impact and could roll around in the fuse possibly to get snagged by a servo line, and wouldn't that be neat. Too dark now. so took it home. Fuel line klunk had made a serious U-turn and would not shake loose.
Don't know all this warranted an answer about ballast, but might keep someone from making like mistakes.
