Of the ARFs I have seen/flown, the SV-11 was clearly the most advanced and the best flier.

Matt....I agree with Brett.
I have three SV-11 arfs set up for glow with the ROJETT 67.
As you know...they fly great.
Randy Smith spent a lot of time and effort getting the mfgr to properly design the control system and install it correctly.
There is no need....on THIS arf to use an after market control system.
