Yes, I do know that lighter flys better. but I am lazy. I bought the plane used.

Wade,
I am running a TT46pro, w/ moosecan. NiMh 720 MH 6volt batt. 8oz tank. stock landing gear, and wheels. I am running 5 standard JR 517 BB servos. Stock motor mount.

I got this plane used, it already had the mount tapped for a OS46. So I just bolted my TT46 in. weight is not @ 4lbs dead even. No extra weight added to get it to balance. CG is perfect, I built me a little tray over the back servos, to get my CG right. It flys great, just a little heavy. Likes to tip stall.

If I do me another one. i would definately go with a my OS32SX. Or even a 46 LA. There is a guy at my field that has one w/ a stock 46LA and hovers great. If I went with same setup exept for motor:
swap to my OS32SX I could save 3oz. but if I wanted to do a little work. I would do this:
Swap throttle servo to a micro save another 1-oz.
Swap rudder to a hitec 225. Save another 1/2 ounce.
Get rid of switch save another 1/4 oz.
Swap out 8oz tank to a 4oz tank, save a little bit more.(don't need a 8oz tank on a .32, you could fly for over 20mins on a 8oz.
grind motor mounts down. save some more.
since I don't need to battery at the back on top of servos, because I don't need the tail weight, move battery under tank. then take out platform made, save maybe another oz.

With a little work, this plane could come it at 3.5lbs give or take a couple of oz. A OS32SX with stock muff/w baffle removed will hover a 4lb airplane, and pull it good. But if you can get the weight down to 3.5-3.75lbs. Pull out would be alot better.

Last year, I flew my OS32SX on a 4lb menace and it would pull out of a hover with ease. I now have it on a new menace that weights 3.5lbs and it shoots out like a rocket.
