On my 7-CAP it's right there with the V-tail, flaperons , etc in the secondary programing. Once in the Mode/Page selection for all your duel rates and trims, etc hit the button again to get into the mixing function.

Guess I'll be getting a new wingset and cowl from VF soon. Had a freak crash last Sunday while on final with my Edge. This huge black wasp landed on my arm while I was about 6 to 8 feet high on approach to the tarmac. The wasp was stinging and biting , felt like a hot needle. I took it as long as I could but had to take my left hand off the radio to try and shake him off. It all happened in a flash. Busted the wing up in three places , tore the cowl to shreads. Damaged one of the wheel pants slightly. The rest of the plane was in mint condition. Didn't even chip the prop. Just another example of how tough these VF ARFs are. Most planes would have been garbage can food after that crash. Worst part was that the Saito100 was really running great . Had vertical forever with the 15x6APC.
I've heard of weird things happening like this before. Sweat in the eyes. Spacial disoriantation. Stray dogs . Guess it's all true.
