Cg

Start with CG of 58 mm from LE (~25% chord) and moving toward higher numbers. I'm now settled at about 95 mm (~45% chord). Do some experiemnts and have fun.

Congraduations!

Great to hear there is another Manta completed.

Regarding the aileron setup, Dr Drela's SGII plan is a good reference to start with.

As for turn, I use mostly rudder/aileron. Here is Dr. Drela''s description on efficient turn when thermaling -
Using the Rudder in Thermal Flying

Have fun,
Geode

I don't have a source for tail booms so I'm wondering what diameter tube would work as a replacement?

I have a draft version pod that I used for Hyperbolic Manta. Should work just fine for Manta too. Check your email for plans.
