Quote: "David Vaughan reviews this attractive .20 powered aileron trainer.

...Before we left for the field we made a careful check of all alignments and control surface movements (all as suggested in the plan) and engine downthrust and side thrust. Since all of these are built in for you it would be hard to go wrong, but you should always check them out anyway, never take them for granted. The Centre of Gravity was put where it ought to have been by using the battery pack as movable ballast (it needed only a small adjustment). The new radio has its range checked on the field and were ready to go. I am probably as tired as you are with the cliche: it flew straight from the board. I am relieved to say our Pilot trainer needed a wee tweak of aileron and a tiny touch of up elevator. Otherwise FSFTB.

I, also, hate the eulogies about kits that can be found no fault with - but to be honest I would have to descend to nit picking to find fault with this kit. Oh all right then, I do not think it is the prettiest of machines, not to my way of thinking, but I must say that after years of flying scale models, it has been some time since I had as much fun as I had with this model. It is of course grossly overpowered with the OS.25FSR, but you sure can chuck it around some. Oddly enough at tickover it can be flown very nearly as slowly as my STOL that has the other OS 25FSR in it. Sensibly, a tame 20 two-stroke or even better a 30 four-stroke would be ideal for a beginner.

The model is stable in all aspects and when throttled back and trimmed out for him Rollo finds it easier to fly than he did the STOL. With coupled aileron and rudder switched in he can now fly well enough in figure eights for me to relax and put my hands in my pockets. The last time out I talked him round a loop, he promptly did five more and had to be restrained. Before long he will be telling me how to to it (guess who has had the only crash with it so far? - well I did fix it again.) Until then he needs me to take off and land for him!

In conclusion, I can genuinely recommend the Pilot Ace-20H trainer as being ex-cellent value. It goes together like a dream, not pretty perhaps but totally business like and functional, 'user friendly' as our computer cousins say. All the hard work and tricky bits are done for you, just follow the instructions, and success should be guaranteed. After all, a ten year old did do it! "
