.50 mount problems (help)

[robbin wilham]

hello i guess everyone thinks i ask to many questions but i believe this may be last for a while sorry, ive bought the .30v2 to .50v2 conversion kit and it comes with the tt polished aluminum motor mount that has 3 holes on each side to frame ,when i sit the motor down on the mount the holes are wider than the holes in the motor itself,and when i finally got the motor screws in it warped the mount inward alot and now the mount doesnt fit flat against the frame, so what is wrong and will this be alright ,here are some pics of what ive got and it shows how the mount is angled in

This condition is definately NOT what you want.
What size engine is that you are mounting ?
Sorry, just had to ask, as it's hard to tell from the photo.
If it's a tt 50. Then I think you have received a 90 size mount.
That would be my guess.

im using the tt.50 and ive checked and its the mount they say use ,they say that the mount is wider than motor and use spacers but by looking at it i would think spacers between the motor and mount would make the mount even wider,the .50v2 manual shows how it works but i cant figure it out ,here are some pages from my manual showing but i cant understand it ,maybe im dumd i dont know,thanks

If you use the spacers provided, as instructed, they should prevent the mount form flexing and hopefully maintain a flush fit for your mount into the heli frame.
They should not make the mount any wider than it already is. The are provided to fill the gap between the engine and the engine mount sides. Again preventing that flexing condition
exhibited in your photos.
As to the " engine mount" hole spacing being wider than the "engine" mount hole spacing.
I use an OS 50 and the holes line up perfectly and do not require the space shims.
I have no experience with the tt 50 engine.
You may have to elongate the "engine" mounting holes for a perfect fit to the mount if they do not line up perfectly.
But I would wait to see if someone else may read this thread and give you further assistance.
I hope this is of some small help

Looks like you are using the os mount, I think that the os and tt are different but not 100% sure
