Chad,

I know you are taking Full Scale lessons so we will use that and assume you are in a Cessna 150 or bigger which will help explain what Bruce is talking about

Very early in your training you should have gone through stall training. You should know that a plane can be stalled at any airspeed. So knowing that, what actually is bringing on the stall? I will give you his much. yes speed has something to do with it but not in the example I am going to explain.

Angle of Attack (AOA) has everything to do with stall speed. Exceed that angle and the wing stalls. Exceed that angle in a turn and now you have one stalled wing and not the other. Guess what happens now, snap and spin. Now all of this is happening at full throttle and at 120 mph

Now you ask, if speed does not matter, then why are we taught to keep speed up to keep from stalling.

As I mentioned, speed is only one factor in a stall. AOA is the other. and now to really confuse you G load will create an aggravated stall that can be extremely violent.

So now take the same plane, flying straight and level, it's moving at 120mph but it's normal stall speed is 55mph. At 120mph you roll into a 45 degree bank and yank back on the stick to keep it level, you just added 2 g's or more depending on how hard you yanked on the stick to the plane and now your stall speed increased to roughly 70mph and as long as those "g's" are still there and you are slowing guess what will happen at 70mph per hour. Point is stall speed increases with G load. Yank too hard and the G loads can overcome the design of the plane itself and pull the wings right off. A good visual example would be to take the Stik you are going to buy and dive it from really high up at idle. At the last minute pull out hard and watch what effect G load has on the wings. I do not recommend this as I am trying to make a point.

In the past I have mentioned that the only thing that really transfers from full scale to R/C is aerodynamics and the stall is an aerodynamic property.

The above example is not that accurate when it comes to the speed examples so please be nice if I got something else wrong.

I do sincerely apologize to the original poster of this thread...
