Throttle servo not working after a semi hard landing

[obbi13]

Hello Forum,

I noticed today that during a nice bashing session when I landed my savage semi hard (and sometimes soft) my throttle servo went unresponsive (like dead). I had to turn the receiver off and back on to make it work again. Do you guys had experienced this before? What could be the problem.

like I said a power cycle of the receiver and everything goes back to normal.

my set up is:
- Spektrum SR3300T 3-channel receiver with built-in telemetry
- temp and rpm sensors connected to the receiver
- stock servos
- hump pack battery and classic batteries as a backup (when hump pack is drained).

check the leads and see if they are loose?...test another servo and rx to see if it is actually the servo and not the rx...my futaba 3pm fm radio had a glitch only in the th servo and I switched several rx's and servos...I ended up switching the tx and guess what it was the tx not the servos or the rx!!
Do you have a friend with the same radio as you...try their rx in yours and then your rx and their tx....worth a try!

Hello Jcam,

currently I don't have another TX, but I can try with the extra little RX that came with my TX. I checked the leads and all the connectors and everything is pretty tight. The weird part is that I can use it all day long and it will work perfect, but as soon as I land a jump or if I bump my savage hard enough the throttle becomes unresponsive, steering still works though.

Id start taking the servo apart and looking at the guts from the wire harness to the gears Cheers!:beer:

yeah what piper said...might be a loose wire connection on the inside of the servo...do you have a extra servo to throw in it to check?
