supertiger i am also going to try a tune pipe on the rcs as the cowl is going to have to be butcher seeing how i don't have the RE version as you have. I noticed that in your pic and said Hum!!
The 18 x 6W has very good speed compared to the 18 x 6 Mejzlik and pulls very hard on this light set-up.
Now on to the funtana i have that thing the Desert Aircraft one and i did pulll my RCS off of this to go ZDz 40 route wow

that was the ticket.....
PS gas engines have a way of doing that to you oops it you forget your glow lighter or god forbid the battery dies, or you forget 2 bring the papertowels for glow clean up, no worries on the gas deal
