I want to add floats to a plane (maybe a GWS Moth), and I am wondering how you guys mount them. Also, how do you know where in relation to the CG should you mount them??

Anything else I am overlooking?

This will be my first float plane.:)

Thanks. Andy

alienx::Their set-up so the wheel mounts will be the front and where the back braces are put the same gear mounts (they give you two when you get the plane kit)in the back where ever they line up back there, the last two I did (GWS) worked well that way, your bub, stevecooper

Thanks. Seems like this is going to work out nicely.

Gonna be motivated now to finaally build that Moth.

I like your cow!

This will vary slightly depending upon your plane's particular characteristics.

The "rule of thumb" is to mount them with the step appx. 1/2" behind the CG. You can then tweak from there. You should also mount them so that the top of the float is parallel with the bottom of your wing. Again, different planes like different float angles ... so you can experiment with this too.

I was wondering about that too. Thanks.

I haven`t followed those, but since the link is stored in my Favourites I just would like to share. Hope this could help you ;-)

Happy landings.

If your wing is a symmetrical or semi sem. you will need a few degrees of positive angle relative to your floats as this type of wing needs some angle to get flying.

If flat bottom mount parallel to bottom of wing as flat bottom wings make lift with out angle.
