Back or front of "Firewall"

Depends if you grew up with brushed Graupners ( in back of firewall) or fuel i.c. motors, what you think is normal.

There is a reason to put the motor in front of that mount in the EZ II, though. You need less nose weight. A two ounce motor with its CG an extra inch back of the plane CG needs 1/3 ounce ballast or extra battery weight 6 inches forward of plane CG.

I've put a back plate mounted motor (KMS 31/21 from Hobby People) on a similar sized Push E Cat, but needed to design my motor mount so it's closer to the back of the pylon. That's shown in the picture, with an APC 7X5 E prop mounted.

I have a similar motor mounted on the front of an MSComposit Citabria, in front of the "firewall", so not all European models have it in back. My Blu-Baby 42 high winger scratch built has a HiMax 2816-0890 out front as well.

So you've got choices with the EZ II. A) Find a motor with the shaft going through the fixed end, 0r B) change the mount and add nose weight, or C) slice off the pod and glue in a firewall mount.

Guten Tag
