Default RE: yellowaircraft old a-4 help

Mike,

Ummm.....you don't necessarily want to have more throw on the elevator than what's called for. 3/8" may not sound like a lot, but the ailerons are very effective on this airplane. Like it's full-scale counterpart, this A-4 has a roll-rate you wouldn't believe. The amount of aileron throw has nothing to do with the stall.

Speaking of the stall, you only need to know that it's abrupt. It is very consistent--and will stall the same way each time if the circumstances are right--but there's not much in the way of a 'warning'. This plane doesn't mush or buffet before the stall, it just tips out. If you know what the stall angle is, you can fly this airplane for ever and ever without a problem. Just make sure that if you're turning tightly at low speeds, you've got a good nose-down descent happening. Better yet, avoid tight turns like previously advised. This airplane will high-speed stall, too, if you overdo the throw or pull such a sharp turn that you load up the G's and achieve that angle in a tight turn.

It all sounds worse than it is if you just stay away from the dragon. My then 13-year-old nephew soloed (then got his turbine waiver) on one of these as his first jet. He got 83 flights on it before his uncle mortally wounded it. All he did was go up high and test the low-speed stall. The high-speed stall never happened with his particular jet (though it has on several of mine). BTW, it was powered with a BVM 96SE and Viofan. It hauled boodie.

Good luck!
