thanks at101, yes i have had a look at the guide for the trainers which have been listed but dont know which one to go for...

i mean i dont understand what is the 4 channel / 6 channel - for RC ?

what is 4 servo ? 6 servo ? 8 servo ?

Also I noticed that engines are very expensive, thus want to buy a engine which i can later use on another plane - when i kind of graduate from the trainer plane.

Pls adv.
