TBM 30% magic hand yak
This is my latest project I just finished up. I have 1 flight so far and I think this is going to be a winner. My setup is a Neu 1521 3d 6.7 gearbox, 12s 5000 thunderpower batteries, apc 25 X 12.5 prop pulling 85 amps and 18.7 lbs ready to fly. Here are some pics and I'll try to post more later.

Re: TBM 30% magic hand yak
Thanks, The plane came out tail heavy with the 2 stab servos in the tail. I had to add 1 1/2 lbs of lead in the nose to get it to ballance. This put me at 2 oz shy of 20 lbs. I got rid of 1 servo and made the other a double pull pull and this got me down to 18.7 lbs. I had to rob my only 5955 from rudder to elevator for the twin pull pull. Now i got servo blow back on the rudder using a 5985 servo and only a 5 volt bec. Things will get better when I swap out the servo for a 5955 and get a 6 volt bec.

Re: TBM 30% magic hand yak
OK i have a couple more flights on this plane and I am really starting to like it. I tryed a new prop the vess 26B. First let me give you some # to compare. The 25 x 12.5 prop works really well and pulls 74 amps on the clamp on meter. The vess pulls 72 amps. Now with the spinn 99 controller I get 74 amps for the apc and 90 amps for the vess. Let me tell you the vess is a stump puller. I was sliding down in a hover and when I nailed it it jerked the plane hard and climbed out great. I think thats why I got the 90 amp reading from that 1 maneuver. For those of you running the 25 x 12 prop I think you can get away with the vess either 26A or 26B. Less speed but great pull out.
