Hey group...im new to this group, well I use to post here about 6 years ago but a hiatus from the hobby has kept me away. At any rate, 6 years ago, I had a tower trainer in my garage that I wanted to convert into a seaplane. I went to the local hobby shop and picked up a set of ABS plastic, one piece floats (made for a .40 size) and mounted them to the plane. They were mounted correctly and straight and the plane taxi'd quite well in my lake at low and high speed passes. Well, i finally got the nerve to take her up. Her powerplant was an OS.40FP,which was more than enough pre floats. Well, I lined her up at the end of the lake and applied full throttle. About 50 yards into the run she was barely skimming the water as if trying to say "rotate, rotate" so i pull back slightly and she pops out of the water....everything was great until she left ground effect. The plane shudderd and shook and the left wing fell, a wing stall....but on a tower trainer?! Needless to say she entered the drink on her back...Well now, 6 years later I have another tower trainer that a buddy gave to me and I would like to make it a seaplane as well. My question is, what did i do wrong? was the plane under powered? Is there any tips I should be aware of? Keep in mind, I was flying for 10 years pre the crash so i have some ok flying skills (at least I like to think). Any input?
Thank you
Charles
