My Gremlin, finished a few weeks ago, is a ball of fun. I have a second one in the garage, ready to start on.

I have an OS .46AX on mine, which is overkill, but who doesn't like fast and vertical climb. The next one will have working rudders for snaps & spins.

Gremlins are easy to build and a ton of fun for the price. Mine is covered with colored packaging tape. The elevons and fins are in Monokote.

Yes, it is a Thunder Tiger muffler (or something else). I bashed the OS one.
