Thanks for the very detailed and informative response!

I am not too happy about the extra forward CG location since bearing in mind I'm considering a taildragger, it could lead to a stronger tendency to nose over.

Seems to me the RC balance point, or somewhere in between the RC and CL recommended points, would be the reasonable place to start.
A more forward CG would also mean a higher stall speed so - why spoil the model?

Anyway, what is also obvious is that adjustable leadouts will be necessary even though not called for on the plan, in order to get the best out of every CG position.

BTW does all this mean that short nosed protoypes e.g Sopwith Pup/Camel, or Gloster Gamecock, being difficult to balance for RC, would be even worse candidates for converting to CL?
