Well just got back from a trip today down to the Hamiltons clubs float day at a smallish lake just west of Gordonton, about 1 1/2 hours from home. There was a good turn from the locals about 20 guys with most having been on water before, not like yourstruely. I had a bit of a learning experience. I set the floats up right with the step just behind the c of g & the float length 3/4 the plane length of my yellow AT40 (has a 65AX in it so overpowered). I looked at everyone else’s setup & they looked to be the same except their float fronts were forward of the prop??? bugger 🤫 I put the plane in the water and the water line was half way up the side of the floats??? I thought to myself that isn’t good. There was a few comments from the people in know that the floats need to be a bit longer & I was thinking the same. So I got the engine running and put her in the water. The wind down there was an easterly and not to bad. Most of the foamie planes were handling it ok. The problem was you had to taxi out to the other side of the lake & take off back toward yourself as the wind was coming from behind us. Anyway the first thing I noticed with my plane at a slow taxi speed I had no or very little rudder control. I did have a water rubber. It would turn left a little but no right turn. Well anyway I manage to line her up cross wind a bit but as soon as I started to advance the throttle the nose of the floats tried to turn into a submarine & I nearly flipped her on her nose. So I slowly taxied her back to shore with left type turns. And I put her back into the car.
So what I learnt was I need longer floats, about 6 inches past the prop, maybe a wider stance & a bigger rudder on the plane and maybe two water rudder? All in all a great experience even though I didn’t get in the air. I ended up chatting / catching up with some of the Hamilton guys who attended the scale / warbirds events at Matamata & Hasting. So if you every want to try float rc flying the Hamilton guys are having two more events before Xmas, one on the 27th of September & one on the 22nd November. Just Google Lake Kainui, Horsham Downs.
