da rock... You seem a little put off by my reference to the "aileron differential thing" and I appologize for that if you took offence to my wording. What was intended by my comment to dgrant was to say that if the plane is built according to GP's instructions, it will still fly just fine. Maybe not perfect but nevertheless, just fine ! You're absolutely correct when you state that I (or anyone) who hasn't seen the alternative has no idea if the alternative works however, I never said anything about it not working as you seem to think I did. In fact, when I read about it (the aileron linkage mods) in this thread, I was quite intrigued, interested and very impressed ! Let's face it, the Skybolt is not a high-end, high-performance aircraft but I would suggest that most that own it do a lot of casual flying with some simple aerobatics and would be more than happy with it just the way it is. The problem with forums is that there much like e-mail... People get 'bent out of shape' when they read other's comments without stopping to think about what is being said. They're too quick to judge and fire-off a 'snot-a-gram' when they're a little offended for no good reason. Enjoy your aileron differential !
