View Full Version : Help elevator control arm and aileron/pitch arm (hs65)
I have just installed HS65mg servos on my bird and the Elevator control arm (the one with the push pull linkage) hits my other servo arm. My question is for you guys using HS65 what servo arm are you using and how many holes out is the ball. Im using the the second hole out from the center screw. The only time it seems to happen is when Im giving it positive pitch with forward elevator. Should I just undo my elevator control arm from the control lever and move it slightly?
thanks

Hey nim, I used the stock HS65 arms as well and noticed the same thing. I have the balls on the third hole from the centre with the balls on the inside edge and trimmed the tip off the horn on so it doesnt bind with the elevator. Works well. Will see if I can get a pick on here for you.
Here you go.

Nice looking job Sea....
That gives me a good idea of what mine will look like once I get those 65HB's installed.
:D
Thanks for the pic that really helped out. When I get home I will make the adjustments. I cant wait to fly this thing now that it has the new servos on it. Ive got two kong packs that I still have to put connectors on it so I can give them a try.
Thanks again
I did the same with my elev servo on hs65mg's. you'll have to play with the travel adjust in the radio to get the swash level at full and low stick. the Servos are great on the head. besides not stripping gear teeth, the heli reacts better with these then the stock servos. and once the swash is level.... wow. so stable.
how did you adjust it in your radio? what are your settings as far as epa go for the elev, and aileron. I noticed that when I move the swash up and down one side tends to move up further & down than the other.
does both of the servos in the back have the ball on the inside of the servo horn or just the one side shown in the pic.
thanks,

Hi nim, I didnt have that problem, mine moves flat through all pitch ranges. I have the balls on the inner side of the arms all round now.
If one side is moving further than the other then you will need to limit the servo on that side, but make sure the balls are all equal distance from centre.
The rear top servo (right side) is Aux1 what translates on the TX to Pitch channel, the lower servo (left side) is the Aileron in the travel adjust menu.
Adjusting the right (or pitch servo) is pretty easy, if its too high at full pitch, just reduce the travel adjust when its set to full high stick and same again for full low stick.
If the left (aileron) servo is out, at full throttle stick you will need to bump the aileron stick left or right slightly to make sure you are adjusting the correct endpoint.
Hope that makes sense.
Its funny I knew how to do it but didnt remember it until your last message thanks for the jump start my brain kind of stalled. they now move all at the same rate.
thanks
