help!!!!! ok well my dad went the route of brushless for his flatana, but the rimfire doesnt fit flush on the mount like its supposed to. part of the rod and back silver collar thing extended too far, and the collar doesnt fit through the hole in the mount??? is there a way to remove the collar and put it back on behind it, or what has every1 else done?? thanks let me kno asap!!!!!!!!!

Take an allen wrench and take the coller off.

but if i do that, wont the motor come apart???

Its there for a reason, I had the same issue with another plane/motor combination and I made a hole in the firewall to enable it to fit flush. If you don't have a firewall type and its a motor mount issue only the buy spacers and longer screws to compensate for the spacers. If you can't find a spacer then you can stack washers in place of. If you have an Ace Hardware in your local they have quite a good selection of hardware that would be helpful. I hope this helps if only a little, good luck.

but wat i dont get is Great Planes supplies a laser cut mount for the rimfire on there flatouts......thats supposed to bolt right on.......doesnt make sense to me that it wouldnt fit or that id have to buy longer screws and such...........odd...........

Use a dremel or drill bit and make the hole bigger. If you don't have either, use an exacto knife.

I tryed to use an exacto knife on my first flatout but soon realized that that would have taken way too long so i had to bust out the old dremel; i showed that motor mount whos boss

I took it off. It's only there to let the prop adapter fit. It doesn't hold anything on. If you're mounting it in front of a firewall you just take it off, behind a firewall, leave it on.

I read either here or one of the other r/c sites where someone had removed it and it came apart in flight. Can't find it now, been too long ago.

Really? I've gotten over 200 flights on it with no problem. It's flown about 3 different planes and survived crashes that totaled the plane.

Just what I read, never know, someone may have just been fantasizing.

Just take it off. It doesn't do anything. The set screw isn't even on there very tight.

if thats not wats holding it together then what is?
i have two rimfires so if one comes apart in flight ill always have the other one
