![]() I've got a couple more photos I'll post when Photobucket decides to cooperate. In fact, I just bought some towerpro mg90's for my boys' Dromidas and they too were a nice improvement for very little money.Ī couple mm's taller than the hexfly it replaced, but it does have more meat on the mounting flange: I haven't got the radio dialed in perfectly yet, but overall I'm very happy with the towerpro's and would absolutely buy them again. I was able to turn the front at a stand still in grass (2.2XL swampers + wheel wideners) and it was able to turn in a few spots on my rock pile that the steering would have stalled before (obviously the mg958 can still stall, just not as easily.)Īfter that short test I decided to go ahead and put the other mg958 on the rear too. When in crab steer, the mg958 turns much quicker than the hexfly and with significantly greater force. don't waste your money on the expedited shipping!) I got the front mounted up on my RS10 and left the stock Hexfly 15kg on the rear for a quick test. I got my servos a couple days ago (took right at 2 weeks. I'll update this post later if I run into any durability or other issues with it. The PCB and IC control system has been modifed to incorporate continuous rotation in. ![]() Bottom line is it is a decent upgrade over the stock servo for the cost, though not quite as beefy as I hoped it would be. This servo motor is an upgrade of the well known TowerPro MG996R. It still is not strong enough to move my tires lock to lock at a standstill on a high traction surface though it does better than the stock servo. It also doesn't have the buzzing issue of my stock servo. It ran me $12 shipped.įirst moves my wheels with far greater speed and authority than the stock servo. It is rated at 18 kg-cm at 4.8 volts (20 kg-cm at 6.6 volts). This somewhat precluded the very high torque servos as they both cost more and would require an external bec (castle creations 10 amp plus castle link plus receiver bypass adapter would be $48 plus shipping even before the cost of the servo). It also buzzed quite a bit when turning to full extension and continued to buzz after recentering until I moved the truck forward/backward.įor my upgrade, I didn't want to spend a lot as I'm fairly budget focused for this build. The stock servo is rated at 9 kg-cm and was unable to turn my tires lock to lock at a standstill on a high traction surface. ![]() The unit features a central alloy casing, and all metal gearing. With these changes my stock servo was struggling. The MG91 from TowerPro is a digital 13g metal gear, double ball bearing servo designed for RC helicopters & airplanes, but useable in just about any servo situation we can think of. I've added a fair amount of weight over my front axle (extra 6.5 oz per wheel, a pot metal axle housing, front placement of electronics), increased my steering travel through grinding of my steering knuckles and axle stubs, and added sticky tires. ![]() I decided to upgrade the servo of my Everest 10. ![]()
