RE: First floats
No I don't think thats over kill You are rite you do need the spreader bar on the back..I would not put a servo to retratct your water rudder though...Just let it flip up on its own...If it hits something it should be able to kick up...It is only usefull when you are going slow..As soon as you pick up speed the air rudder takes over....You are doing a great job..Make sure your step is about 1/4" to 1/2" behind the C of G..It can be anywhere form on the Cof G to a little behind ..
