Danny, My plans are a little different to yours Iam guessing if I can get one of these Long-Eze's, see pic below re- what engine for my Long Eze...
If I was going with glow engine possibly either a Moki 1.8 or a 4 stroke 180 size engine would likely be my choice.....

Rube, Thanks for the feed back, as to grass field landing woes what about adding a little crow into the ailerons and landing a little quicker??? that would avoid the canard stall, that said Iam suggesting this based on having seperate servos for each aileron.
