allora o capito perché* i servi vibrano e 1 di loro si e bruciato perché* non possono lavorare a 6 volt ma solo a 4,8 volt infatti a 4,8 non vibrano piu

I have 5 of these servos which I use for throttle. I never had an issue with them but they are noisy on 4.8v. I've read that this is normal for digital servos on the lower voltage.

I have had 4 of these just delivered, have installed them for ailerons and flaps, but they all judder in the neutral position and judder during the operation which does not help. have even tried using 22swg leads but no help there. I am using lipo with reduction to 6 volt can anyone help before I have to go though the rigmarole of sending them back????? Rolly

Roland, did you ever solve the judder? I had 4 of these laying around and put them in a P-40 and they are noisy when sitting neutral. Not sure I would trust them in the air.

Never had a reply from site so sent them back and recieved a full credit within 3 weeks of posting, but no credit for the postage €*7.65. So partly a result, never had a reason for the the problem either so may be inherant. Rolly

do not exeed 4.8v input this will stop the jitter. reason to much power it cant handle it all at once. i know it says it can take up to 6 but it wont . but it works great on the lower voltage just wont have the punch or speed it says . yes they should redo this one.
 tommy2toes 2623 points
sorry but also you could be getting noise form the esc you can put on a filter for that. or put a ferrite ring on that wire from esc wrapped 5 times through the ring that cancels this jitter as well.

Brilliant servo for 12th scale racing ultra quick response and can withstand some super heavy impacts. Needs a tx with dual rate to restrict its reactiveness as otherwise can tend to be a bit twitchy however perfect and surpasses the most used one in our sport which is the futaba s3003. at half the UK price for the afor mentioned servo as well this ticks all the boxes. We are currently trialling it with some of our drifters and early results show extremely positive. Another hidden gem from HK

If they are digital or analog.... I can not figure that out. But for sure they are solid, precise and fast! At local shop at least double the price for the same quality. I use them on 1.5meter plane and perfect fit :)
