Default servo speeds

Hi Guys,

I would appreciate your advice. I have two JR 537 servos on seperate channels connected to my Ucando60 elevators. The left elevator is connected to the gear channel and the right to the elevator channel on the rx. I use a JR 2610 TX and when I raise my elevators the servos travel at different speeds. the servo connected to the gear channel is slower than the other.

I worked out how to increase the travel for the servos and they both travel as per the high or low settings to the required distance. however the servos dont get there at the same time.

everything is the same in regards to horns, the horn attachment &s the horns themselves. Is it a bad servo or is the fact using the gear channel the cause.

Any advice is greatly appreciated

TRY SWAPPING THE SERVO LEADS AT THE RECEIVER AND SEE IF THE PROBLEM SWAPS SIDES. IF IT DOES, ITS USING THE GEAR CHANNEL. IF IT DOESN'T ITS THE SERVO.
GOOD LUCK

Are both leads the same length, and same gauge wire? This could be a problem. Why not just get an 8 dollar reversing Y and be done with it?
BTW, do you mean JR XP 6102 radio?
You should be able to mix the gear and elevator at 1:1, so that shouldn't be a problem, I don't think.

Hi!
Have you checked the angles (servo arm to servo linkage angle).
The geometric must be same, other vise there will appear to be a difference in servo speed.

Regards!

Default RE: servo speeds

yes jaka I have . everything is mirrored side to side. if I used a Y harness as suggested by 2slow2matter then I need a servo reverser. I have used this system on a Harrier previously and did not encounter the difference in speed. But I will try all suggested to investigate.
cheers & thanks again

Check the mix %, not on EXP on either channel and Trvl Adj setup in trans the same. Some times I have had to increase the Trvl Adj on the mixed channel on JR equip to get the servos to travel at same speed and distance. I use JR X-3810
