Trainstar Floats

...working this out

The landing floats for the Trainstar are really good however, not being specifically intended for the Trainstar, I need to figure out how best to install them.

So far I have decided to use the two undercarriage mounts on the Trainstar, the forward mount which is used as the main undercarriage mount in taildragger configuration, and the rear mount in tricycle format.


This seems to be logical, however it does require a custom float strut, as the rear mount is about 25mm higher than the front mount. Nevertheless, this shouldn't be too difficult to achieve (just getting some 2mm aluminium sheet and putting a few bends in it).

I have assembled the rudder, which just needed some cleaning of the mounting shaft to allow smooth movement, and the looped elastic-band works well to pull the pivoting rudder down.

At the moment I'm thinking that I'll use the provided cables to actuate the rudder, which connect to the rudder control horn on the plane. While I like the idea a direct-acting servo, this would require cutting a hole in the float which I'm not so keen to do...
