how about a 4*40 or even the 4*60.
I agree that either of these might do well, but tower had a phenominal sale on their trainer .40 a short while back. It's normally 69.99 and it was discounted $10 and if you bought it in a combo with an engine you got a $20 gift certificate, and I had a $20 off coupon on an order over $149.99 plus I get free shipping for being a super saver member. A little math and I couldn't beat a .40 trainer ARF for around $20. Besides, I learned on a superstar back in 1997 and the tower trainer is very similar.
