Dickeybird,
been there, done that... I sent Joe a mail a couple of days ago, but didn't get a reaction. That's why I came here looking for advice in the first place... I guess Joe is a pretty busy guy, judging by his website.

William,
Thanks for the input. You're right about one thing: single engine pilots get lazy on the rudder. I only use this thing when planing close to the ground at very low speeds (3D type flying), and for basic acro of course.
The offset engine thrustlines part in your reply really makes sense. I will be giving that a go.
I also have a very old (like 10 years or so) article somewhere explaining how you can setup your transmitter to simulate an engine-out. I will try that too. It is one of the few old magazines I didn't throw out over the years...I guess that twin must have been in the back of my head somewhere all the time, but I just didn't get around to it yet.
