Well guy's sunday was a Bad day for me i lost my New 30% Yak 54 gasser after some further
analysis and a couple of phone call's to TBM Models . I think i have the reason for the Crash.The plane only had four flight's and the fifth flight it was TOTALY DESTROYED i had no controll over the plane at all she was in a dive about 45 degree angle down and half throtle
Looks like when i ordered the plane and all the electronics the fella that i talked to about everything wasn't quite up to speed on battery & Charger compatability i told him i have the triton 2 charger and the directions say it will charge Li-Ion batteries but he sold me a
( Lithium ion nano phosphate Battery ) which i found out today is more comonly known as
a A123 battery which my triton 2 will NOT CHARGE even though i had it on the charger and it read 8.2 volt's when the charge was done it still didnt have the capacity put back into the battery. Theirfore the voltage droped to low and the the plane did .

I talked to the salesman at TBM Models and he gave me about $150 discount on the new plane Battery switches and two new props i should have it by the end of the week here is the new plane .

Mine is the one on the bottom Scheem #5 Russian Thunder Red/Black/White i think this is going to be even nicer than the other one it has alot of carbon components where the Magic hands Yak had alluminum .
