What the heck? You guys work on weekends? Go fly!
I can't find and GWS "micro" receivers on line. I did find the GWS "Naro" receiver, part # R6NII/H/F. Is that the 6-channel you are referring to?
The HS81 servos are rated about twice the power of the HS55, weigh 2.5 times as much, and cost $7-8 more. I use them on my .25-size glow planes. Definately not necessary if the HS55s will do the job.
After adding up everything I'll need for the Yak 54 except adhesives it comes to $317.49, RC-XPlanes still is cheaper than lesser foamies from the LHS that don't have graphics or landing gear. That earns the Yak top spot on my buy list. I'll have to wait awhile [
], though, because of family commitments over the holidays. New grandson and all that goes with.
