Default flutter on funtana

I am using JR standard servos for all surfaces but the rudder, on the rudder i have a high torque hitech and was wondering if anyone has used standard servose on the funtana. I Haven't flown it yet and just wanted to know if these are good enough cause in the manual it says that standard servos are good.ese are good enough cause in the manual it says that standard servose are good.

i had standard servos all the way around on mine. they are fine. I then moved to hitecs cause i had some long aluminum servo arms for them so i could get more throw, that i didnt have anything longer for the standard servos. I still have them on the ailerons. The have sufficient strength as long as you dont do any full throttle passes. good luck.

i used all standard s3304. i recently upgraded to s9001 in the tail. those with a 6v batt make a good strong fast response. i really noticed a difference. I still have standards in the wings, but those are going soon. I fly a 46.fx with a 12x4 prop and slimline pitts muffler. full throttle provides no flutter. but i also have it propped for slow speed and high thrust for verticals. it also makes for great air brake when i chop the throttle. short field landings are a breeze. i use the tock 2-56 rods with greatplanes ball links all the way around.

i run Tower servos and Futaba 3004s all around, i do high speed blenders, walls, snaps, and just about everything you can think of, and have not had a problem from the time i started flying it last summer.

Hey Kyle,
I've seen your vids and like everyone else was suitably impressed!

A couple of questions though. Where was the balace at on your plane? I seem to recall that I read somewhere it was at 5.5" but can't rmemeber for sure. Mine's at 6" and the plane wants to snap out with a lot of evelator throw and really doesn't want to stand up into a hover. How about control throws, were yours by the book or did you tweak them to suit your style?

you are right, my CG is at 5.5in back. i put big control arms on my servos and moved the clip on the Control horn to the hole closest to the serface (stock hardware). this is my max throw
