Help OS 91 FX
 

I have a os 91 fx and it was in a crash:( (long story) anyway I need a replacement backplate since it doesn't have a remote needle does anyone know where I cand find one? Also does anyone have any suggestions on a 3d airplane that would be a good match for this motor? Thanks for your input!

You can get a replacement for the backplate from tower, just look on their website, I've replaced backplates lots of times. I think the ground likes my planes for some reason. It keeps reaching up after them. I think extreme flight may make a Yak in the size you are looking for, but I'm not entirely sure. OMP also has a profile bipe built for a .91 two cycle. I hear lots of good things about them.

I've been searching back posts with no luck on the preferred .91FX replacement backplate and separate bracket (stay) and needle valve assembly. Are the ones for the .65LA the ones to use?

Further digging found these:
OSMG7152 26582931 NEEDLE STAY 91FX 65LA $2.99
OSMG6997 26582900 VALVE ASSY 40-65LA $19.99
29057000 COVER PLATE 91SX-H $$12.99
