Hi,
I have almost finished my Fun Air 40 3d, when I made a sad mistake. the engine holes where drilled on the mount in
accurately. I have tried to locate a new mount, but all i could find was either too big for this plane or was far to match the firewall holes.
is there a possibility to close the bad holes ? (epoxy?) or is there any idea that can be used??

thanks

I mixed up some JB weld and flowed it into the hole.
Let it dry a few days and retapped the holes.
It has worked fine.
Let it dry real good then redrill

1)this is a black plastic engine mount.
2)what is a JB weld??

JB Weld is basicly a metal filled epoxy. Would you really want your engine held on to the mount by the small amount of epoxy that is left after you have plugged the hole and redrilled?

Is it possible to redrill the hole in the correct position and use one of those brass threaded inserts?

I have drilled out the bad hole/holes to 1/8 inch and epoxied a 1/8 in. dowel in the hole, then redrilled the correct hole locations. Still flying it after many flights !
