LOL - funny or what, I had my first RC experience with a 2 channel 'Gentle Lady' glider, even tht was harowing and required repairs.

Taking off and landing on water takes an additional amount of skill in most cases, so to learn to fly unaided and take off on water WILL end in tears.

I have seem many experienced RC pilots make a hash of water plane flying!

Seriously, please seek some help . . .
