Think there are thirty some types even helos.   I usually fly the trainer type, cannnot remember name think it is a Nexstar fuel and also the electric version.   I have tried  three of the slower ones with the same results.  The jets just go out of sight lol (me)  But on the serious side the above described actions happen.   Like I say can fly the circuits , figure eights etc.   Cannot land to save my rear.   I have tried just a slow glide but  turn to final and all heck breaks loose.  At least I can get provicient in airwork.   gphil
