Canadair Takeoff Technique

...a few issues to address

I decided to get the Canadair as a companion for the Trainstar floatplane, a well-recommended twin-engined flying boat, high-powered unlike the marginally-powered Trainstar in floatplane guise, which should be easy to launch and relaxing to fly.

Well, after several visits to the lake I can attest to the former not being the case, certainly for the uninitiated, and that I have therefore, unfortunately, not been in a position to enjoy the latter.

There are a few tricks, it seems, that one needs to know. I haven't yet been able to test or master these, however I have an inkling on what needs to be done to get this boat flying.

Wing Floats
Problem - the wings floats leave a gap to the water and, therefore, the wings are initially tipped to one side. Unfortunately getting the wings level involves a conundrum; the ailerons are ineffective at low speeds and, if you attempt to speed up to remedy this, the wing floats end up submarining and causing the Canadair to execute a handbrake turn. 
Solution - trim a 5mm wedge off the wing float mounts to increase the angle of incidence of the float. This makes the float less likely to plough under the water during takeoff.

Take-off Run
Problem - as above, so many of the successful launches I've seen are executed with a very short takeoff run. Those that have a longer run are either done in absolutely calm water conditions or are marginal/unsuccessful.
Solution - get the Canadair moving and then quickly increase the power. The effect of this is to cause sudden downforce on the elevator before the Canadair speeds up much, effectively pushing the back into the water and getting it onto the plane almost immediately. Additionally this same effect means the front of the wing floats is rotated up by the same effect, supplementing the incidence modification as described above.

I think there is a knack to the latter solution; I have managed to get it planing in this manner but have aborted the launch due to concerns of the wing floats digging in and causing a crash (splash). I am hopeful, however, that with the wing float modification and a bit of practice, that my next attempt will be more successful...
