I have never used flight stabilisation or a gyro on a plane, I learn't to fly without and its done me no harm. I taught my son to fly without flight stabilisation he is now doing acrobatics more confidently than I do.
I started him off with the basics using FT Flyer, I got it in the air for him 3 mistakes high and said "have fun". He had a couple of rough landings and it took a couple of attempts but he eventually got the hang of it. Then I went from a 2s battery to a 3s and we tried again, he soon got use to the speed and handling.
Next stage was the Tiny trainer 3ch with a 500mAh 2s, different plane different charactersitics. When he got confident with that he learn't how to hand launch himself, then landing under control.
We progressed on to the 4ch Tiny trainer, ailerons took a bit to get use to but eventually he got the hang of it, from then on he never looked back. He even built his own version og the Tiny trainer 4ch and taught himself rolls and inverted.
Its all about having the right plane and taking your time, once you have that muscle memory it becomes second nature with the controls. Its just a matter of getting use to each planes flight characteristics after that.
I am just in the procss of building him a Simple Scout, so he can practice taking off and landing with a model using a tail dragger undercarriage. Once he has mastered the Scout. He can progress to my Volantex Trainstar Ascent, its got a 1.4 m wingspan and he can continue learning with that.
I am hoping he will of passed his safe solo test at the club by late spring early Summer 2021, after that he can then really learn to fly on his own.
