I bought 2 planes from Cedar Hobbies about a year or so ago. The 40 trainer had some real probs: warped ailerons, poorly cut hinge slots, to name a couple. Since it was to be my '1st victim' I went ahead and built it and flew it. Wasn't too bad really, till a stripped servos gear head to a straight headin with terra firma. While the wing almost broke in half, bent the landing gear, the built-in motor mount and firewall had no damage! But in the can it went.
Now the 40 stick (green with Maltese crosses) was a whole different story. Went together just fine. Seems well built, nice covering, nice flyer. Every bit as nice as some of the 'major name' ARFs I have, IMHO.
Pleas note: I never made any attempt to contact Cedar Hobbies about the trainer and it's poor construction. But considering the level of service I received while I purchased the planes leads me to believe they would of made things right.
I would not hesitate to buy from Cedar Hobbies again.

These are my 2cents worth on the subject, may not be worth a penny!
