Worst Trainer?
Heh!!
RCM trainer here, bought the combo from tower hobbies with magnum .40 engine for 150 bucks.
Not only has it taught me how to fly, has survived a horrific run in with a fence post(snapped fencepost in half, just busted leading edge, wing spar intact), duct taped the damn hole in the leading edge, has flown ever since.
It does seem to float more then my buddies hobbico trainer, was wondering if it was just me.
Magnum engine is reliable and strong, people at my club were laughing when they saw Magnum, they all OS people, well, they aren't laughing now, I either lucked out, or magnum makes good engines now. Very powerful engine.
30 or so flights on it now, many run ins with mother earth, all repairable, has a nice grey duct tape pattern on it now, all over, and it still flying strong. I may recover it someday and fix some of the nastier dents, but has served me well.
Solo flying within 1/2 gallon of gas, including 2.5 tanks worth of engine break in.
Mill, the RCM bandit.
