moins bien que HK 922Mostly works, relatively smooth movements with acceptable centering (could be better tho).
Its algorithm for vibration compensation is not tuned properly and can induce flutter if you shake your eleron with just the right frequency.
It burns if overloaded/blocked for more than 15 seconds or so. Fortunately it didn't kill my bec and my model survived.I have used these little dynamite servos to replace Futaba s3156. The 375DMG is a little stronger and a little slower than the Futaba, but at 40pcnt of the price! They are fully compatible with the larger, non-micro series of Futaba horns. You need to use the UBEC set for 6 volts for useful speed and avoid heating the linear BEC. These and the 385DMAX servos have a rubber bushing plus eyelet for mounting. You DO NEED these rubber soft mounts to eliminate the servo buzzing. All digital servos need some damping to stop the buzz, and BlueBird has thoughtfully included these items. My only complaint is that there is some variation in performance from servo to servo. You must expect this problem when you pay prices substantially below market, as we are getting less than first pass inspection quality. There are reasons for the low price.Bought 3... 2 are more noisier then third one... one died in 5 minutes... pay less and risk! doesn't worth!Used in my tricopter project. Have some gear play but still works ok. I will not reccomend it for preciese control but for tricopter is ok!Excellent servos. Can't say enough about these. I did have HS65HB's on my Sport and then swapped to these as a first step towards going FBL and my flip and roll rate doubled without touching ANY radio settings other than EP and ST. Quiet with NO buzzing.I have installed one of this small servos on one 450 size helicopter rudder, in combination with a Futaba 401 GY gyro. For mild flying the servo performs very well, the gyros sensivity was set between 50 and 55 (radio is a Futaba 7C 2,4 GHz.) However when you increase RPM and try some aerobatics the servo is very fast but not strong enough to lock the helis tail. I think is a very good servo, but not strong enough for a 450 helicopter rudder. I will try it as tail servo in my T-Rex 250 and I will post the results.
is very goodthis BMS 375dmg servo is top.Perfect centering and stop position. No slop in gears. I use them in my HK450pro and have around 70 flights without any problems with this servo's. Top servo for top price.Great servo! Super inflated price here, $14.00 elsewhere.BMS 375, I ordered 3servos a a test for my Trex and Hobby King 450 size helis. I agree with all the other positive reviews here, this is a top servo. Perfect centering, stopping, starting and a very fine response on the sticks of my Futaba ff10. Nice item is that there are spare gear sets and that you can use without any problem Futaba servo horns. Again super low Hobby King price here also.
