Hi mate! Mine name is Tony, i'm from Belgium. I've a question about the Futaba hps-ct702 servo? I have 2 of those servo's installed into mine Xray XB4 1/10. I did everything correct but as your car is standing off from the ground then mine front wheels vibrating. If i put mine finger on it, then it stops. If i put the car on the ground it react normal. Some guys say it's because the sensivity of the servo sensor, other saying it's the potentiometer. But those servo's are brand new. From 2 different batches. I don't know if this vibration is normal or not? I never saw this before with mine other servo's? Kind Regards, Tony
I am no pro with the futaba servos yet been running a recently purchased hps cb701 and there is information out there in regards to tuning them. Plugs straight into the transmitter. I dont remember all the verbiage off top of my head but certain settings can calm the servo down so it doesn't vibrate or overheat etc.
Thanks man. But i have a Sanwa M17. Anyway I was thinking to switching. And buy myself a Futaba T10PX. I have the same thoughts as your mention. Plug it into the transmitter etc... But I contacted Futaba. He say send it back to the shop, and they send it for repair if needed. The guy say probably a bad batch? Yea right. The came from a old and new batch. And you wouldn't expect a bad batch of a 250$ servo. Anyways he says that it not will work to setting the servo parameters with the transmitter
I have seen this issue before but I'm not positive on what the pin point location is. In the past when I have had this problem it's on servos that struggle to find their centering meaning that even thought the steering on the remote isn't changing the servo itself doesn't know where the neutral point is supposed to be so it's constantly trying to find it. It is odd that 2 different batches are having the same problem and being they are high voltage servos I wouldn't think to high of an input would be an issue. Have you tried adjusting the BEC in the esc at all? I have seen some servos claim to be rated for 6 volts but act funny until the BEC is turned up to a higher voltage. A final test to run would be to plug in to a servo tester which will isolate the servo telling you if it's the servo or some other piece of equipment in the vehicle. Unfortunately other than these couple options or getting a Futaba radio to program the servo (which still may not fix the problem) there isn't much trial and error to run leaving us at the point of returning them for testing by Futaba themselves. I apologize for not being able to give a more definitive answer but this is where I would start.
If you adjust your droop by axle height in relation to the ground (using droop blocks) and adjust your ride height after moving the hub then your dog bone should sit in the same spot it was prior to changing the height. If you'd like to see how to set droop using droop blocks check out this video : ruclips.net/video/4Xwxf1PJ_T4/видео.htmlsi=sD2BXrXIduHJRbLQ
Keep them coming

Do you have a video explaining the different plates with these rear hubs?
Yes I do! That can be found here ruclips.net/video/QRkUHHpnMvE/видео.htmlsi=f7R3Q0rnJAvqfNB2

I do have a question? Doesn’t changing the axle height also change the dog bone plunge in regards to the height change?
