Herr Piper Super Cub 30'' with floats

I was inspired by light weight builds of Herr kits posted by N2856S and vonJaerschky.
My son asked many times to make plane with floats. So I bought Herr Super cub with floats it is 30'' ws. Ordered already 5g HTX servos 2S 460mAh 26g Lipo and UH1811 10g motor.

Looking on plans right now and thinking - do I really need ailerons?
Or just make it elevator and ruder managed, any thoughts?

At that size I would stick with rudder / elevator and make sure you have about 5 degrees of dihedral each side.

I am half way through building this one my self, as my first foray into the use of tissue for many years ( back to the sixties in fact). I intend to use doculam for the floats although I really dont expect to fly it off water.

It has been sitting on the shelf part built as I have been waylaid by a Tom Boy ( now completed) and the Fokker M10. But I intend to get back to it ASAP.

It is a cutie thats for sure.

I will watch with great interest, good luck with the build.

By the way,

After completing both wings I noticed a fair bit of difference in weight between the two wings, that required an amount of sanding to equalise. Clearly the wood weight was a little different. Its not a disaster but forwarned is forarmed.

Yep, I find that some sticks have a different weight, think that some was dedicated for wing struts some for wing
I used harder sticks for leading edge and lighter for tailing.

motor mount to firewall

Using vinyl panel which I had from old guillows kit parts for motor mount. Added some balsa sticks to make motor sits more behind the firewall.
Do we need down and right thrust, If I will use 5x4 or 6x7 GWS prop?

My guess is yes, you will need a bit of both. With no right thrust, my L-19 won't turn right at all.
