Hmm, I haven't seen the extra vertical fin before, I will have to build one. Is is supost to correct something in the takeoff run, or in flight? Those are some pretty big floats, They must add a bit of weight.
Once in the air it flys alright, It seems to like a little rudder in adition to the alerons to get around, but not sure that's really a fault, or just the dihedral. I am currently running an older os 40 fp so I want to keep everything as light and smooth as posible. The only real problem I was having was the takeoff runs, with unplanned oversteer and resultant spinout. I think these new floats should do the trick, but anything to make it a more docile flier would be helpfull as I would like to try doing a little training with it this summer.
As I said before, this was the RTF version with everything installed, But for $40 I wasn't going to be picky with colors

. Once I get everything else sorted, I will probably recover the underside of the wings, at least the outer foot or so.
