Folks

I have flown CPLRs models using his radio, for many years.

The stick tensions are not high, I would say average.
The reason for the extensions, is because futaba sticks are short and designed for thumb fliers. CPLR is a finger and thumb flier.

With the use of a tranny tray, it is virtually impossible to fly finger and thumb on the standard sticks.

I use a similar system but with a diff tray layout which means I can rest my palms on the side of the tranny case, but I use stick extns, although only such that they fit between the bottom and top of the normal futaba sticks.

hope this is of use to you...

PS - Many european fliers fly mode 1. Perhaps one reason CPLR and his club mates fly Mode 2 is because their founding members were taught by a british club !?
