GP Adjustable Engine Mount
 

Is that thing reliable ? It comes with the kit but I feel the split design does not really guarantee the proper alignement of each side. Especially with all the vibration around that area.
I used a DB engine mount sized for my engine in my first plane and it seems more reliable...
Anyone had a bad experience with the GP adjustable engine mount ?

Phil,

I have used them in a number of planes. In fact my latest plane came with no motor mount and I went and bought one.

I'm running a .70 Surpass in the .40-.70 size mount.
No problems.

Use allen hed bolts to mount motor mounts. The sloted head bolts seem to work loose.

I have used it several times on GP kits that came with it, no problems.

Although I had my doubts about adjustable mounts this is a fine design that works well. As RC Outlaw suggested, I always use DuBro socket head cap screws to attach engines to the mount and the mount to the firewall.

Used it in all of my SPADs and currently in my balsa trainer.
Works great! No problems.

Good engine mount .. two points:-

1/ I glue mine together with CA after the alignment etc has been done.

2/ Make sure there's a large washer under the bolt that bolts it to the firewall, as tightening it without one can tend to push the bolt head through the oval hole.

Otherwise OK
