RE: Is this a good 1st model???
Globe.. I agree with Bruce, however, as training coordinator in our club, we tend to lean toward a plane with four channels, get that aileron training because eventually (probably next plane) you will be using the ailerons.
And, also, bigger is better. The larger trainers are easier to see as well as easier to fly. You may consider something larger, if it's available. I solo'ed with the NexSTAR and, obviously, am slightly biased toward that aircraft. My second was a Tiger 60 (larger yet) and I love it. The two following the Tiger 60 are Four Star 40 and Midwest Aerobat, both 40 size planes.
We have four students in training, three have NexSTAR's and one has a PT-40. All great trainers/flyers.
