Welcome to the Addiction of R/C warmachine,

As far as Hangar 9's P51 Mustang PTS (Progressive trainer system) RTF (Ready to fly) plane is concerned, I heard different opinions, as I got it my first trainer but here in this forum some well experienced pilots/intructors told me that they taught on P51 of H9 their students who never flew a plane doing well, my mustang crashed after doing several flights with instructors, yes, its not a trainer but with droops and air brakes on landing gears and tilted flaps, it flies slow and good but depends upon how good your instructor is. I hope you can learn on this plane, its a beautiful flying machine, but experience told me that its better to fly high winger which is stable than low winger. Well Hangar 9 makes good products, they have a combo package for 40 size trainer which is alpha 40 trainer RTF which has 4 channel radio and .45 evolution engine for $289.99. I think its a good deal for a training plane. Features are here

I hope it would be pretty helpful.

JR makes good radios, Im planning to buy their new 7 Channel Radio which is XP7202 with Synthesized Receiver for $329.


Take care Happy Flying
