My experience with Graupner USA has been perfect. I couldn't have asked for better, and that goes for the radio (MZ24) as well. Keep up the good work!

MZ- 24 repair
Everything went well,the tech was very helpful. The only problem was,with the new PRO firmware installed,the stick mode wasn't set to the normal US mode.. I flipped my idle up switch on my 6s electric plane and the motor went full throttle and ran into my basement wall.. Partially my fault because I didn't remove the prop. Besides that the transition went smoothly and I received my MZ 24 in a timely manner..

Sent my two radios in to have the top left switch replaced to a on off switch normal retract switch that I'am use to. Doug replaced both and all works fine. Thanks to Doug. Charlie Beverson

Always a Marine
Had an accident with my MZ-32. Doug, who is always there to help really did a terrific job repairing it and as usual added a new touch to the motor off feature in my transmitter. Thanks Doug and keep up the good work.
