RE: Are there any CL trainers around nowadays?
Rock,
If you flew CL in the 1960's, you haven't forgotten how. You will be surprised at how much work it is and how wobbly you can be.
If you're interested in training new fliers, as some have mentioned in here a bit larger model is easier to do it with. Typical .35 type profiles... Ringmaster is still available (and the kits are a LOT better than the old Sterling work!) SIG makes a SKYRAY 35 that is pretty sturdy (as well as the original 1/2A version). RSM has a few suitables. Brodak has already been mentioned.
Something like a SKYRAY 35 for you to get your hand back in, then trimmed a tad noseheavy, makes a very suitable trainer. Enough airplane and pull to fly in more wind than 1/2As can handle. Enough reserve maneuverability that even a trainee, after several laps two-hands-on-the handle*, might just be able to avoid the ground with the usual panic overcontrol move. I did mention sturdy?
(* - an excellent way to familiarize a new CL flier is for you to hold the handle from the front while the new guy holds the grip. You take the model off, and when ready get the guy in front of you so you can circulate together with both holding the handle. You can take over immediately if needed. The new guy gets an idea of how much - rather how little control is needed, and how the model feels. As the idea gets through, you can hover your hand in front of the handle until you get confident of 'his' ability. And you can take it back for the first landing or two.)
A SKYRAY 35 can fly extremely well, balanced right. That suggests it can survive some rapid returns to earth and still be there for advancing into fancier flying.
Welcome back!
