Hi There.
New to RC flying, but VERY excited. Wife and kids bought me a Super Cub for Fathers Day. Three flights so far.
1. First was 30 seconds 2. Second was about a minute or so 3. Little over two minutes, but radio lost contact and had a hard hit
Broke a control arm on one of the servos, couple cowl cracks (repaired with GG) New servo today.
Question. I posted a picture of the motor mount. Looks like the mount is designed off center and at a slight angle to perpendicular. Is this right? Inquiring minds want to know.
Thanks and great website!!

Hello and welcome. You're a lucky man to get the wife and kids to buy the SC for you. ;D
As for the mount, yes it is supposed to be like that. This is called the thrust angle and count-acts any forces that are applied to the airframe by the rotating prop. It sounds like you had a fairly heavy hit. It will be worth taking a good look at the whole plane to ensure you've not got any other damage. The firewall (that the motor mount is connected to) is a fairly favour place to have damage that isn't obvious without a good check over. Also check your motor and control surfaces operate properly prior to your next flight, ensuring you don't have any surprises.
Happy flying!

Thanks for the quick reply. From the time I have spent reading the threads here you are an RC legend!! I appreciate the suppot.
The thrust angle makes sense. Should have thought that through. Thanks. I have pretty much stripped the plane down. I think the engine mount is OK. The servos broke loose and I need to replace the arm on one as it snapped. Wing strut was snapped, and the cowl got mangled. I am learning to not have a heavy hand on the controls. Need to figure out why I seemed to lose signal with the plane before going back up.
