I've had my Parkzone T-28 Trojan for about 6 weeks and I love it! Very stable and the performance is more than I had hoped for. It doen't have unlimited veritcal capability ( yet )... but is very stable and forgiving. It doesn't have a tendancy to snap roll if you get it too slow, it just drops the nose a bit and then levels out. Spins are a blast, and just releasing the controls stops the spin and a little elevator and it makes you look like a pro.
I did change the receiver, and put in a Spektrum 2.4 Ghz AR-7000 because of planned mods. The nice part is that in a tight turn is doen't have a tendancy to drop the nose like so many other warbirds do. I've added flaps and I have a different ( read, more powerful AXI 2814 ) motor on order and it is supposed to be equivalent to a .22 - .25 two stroke nitro. Can't wait to see what it'll do in a vertical climb! Waiting for warmer weather so I can check out the operation of the flaps, it should really float in for a landing. Would I recommend it for a first trainer....No; not unless there was an instructor on a buddy box. Can you learn to fly using the T-28 as a trainer with a buddy box, YES, most deffinately. For a sport plane it would make an outstanding "sport trainer". But not for a first time pilot.

Enjoy,
