  • Excellent Servo
Replaced my dual-20kg cheapo servos with this single 45kg Flash Hobby servo. Awesome speed and power on 6volts BEC. Just have to clamp down or adjust your servo saver to let this servos speed and power shine. ✅Quiet - no annoying digital motor noise ✅ Super powerful and fast steering even with 6.7" tires ✅ Thicker gauge lead wires ✅ Very precise, no wandering ✅ All aluminum housing and metal gears. (I think some of them are stainless) I have a new castle ESC and now I'm running 7.4volts BEC. The difference is noticeable! I also bought the 25kg high speed version for my Maxx v2 on 7.4volts. These are now my go to servos. ... show more

  • Steering/Servo Lock
Started out strong in my truck now it just locks up constantly. I have to stop the truck and wait for seconds then it unlocks and center or i have to keep turning the transmitter off to reset the servo.

  • Good for the price
Honestly this servo is great for a losi LMT even mounted sideways torquey , quick. But the only thing I will say is that it turns about 4mm right then left , which isn’t a big deal but it could affect racing on a high traction surface . Impressed for the price

  • quiet,
Was buying another brand 45 KG servo and thought I would try something a little higher quality. This servo is definitely higher quality, aluminum case, gear mesh is almost silent, very smooth steering and fast enough for me. Highly reccomend! great value for the money.

  • Strong!
I got this for my 6s Kagama. It’s way better than the stock 25kg servo. Faster and more powerful. Good upgrade!
