My cousin Kyle has decided he wants a foam RTF 4-channel trainer airplane ( from post
http://www.rcuniverse.com/forum/m_9602640/tm.htm ) but will go with the 3-channel if you think that choice is better for him to learn on, and wants opinions from you to decide which.
His choices are down to these two:
1) Dynam Sky Trainer 182 - 38" 4CH RC Remote Control Electric Plane w/ Brushless Motor LiPo RTF

2) Although he has his mind set on 4-channel he will consider the Mini Super Cub RTF if you suggest it would be best to learn on a three channel.

It has to be foam and he will not even consider a balsa RTF.
