High performance servo recommended for Airplane & Helicopter (Tail)
Unit Weight (g):
I used two of these servos for rudder on an Aviation Design Scorpion jet. This is about the same size as a Hitec 5085, but stronger and less gear slop. Very tight gear train and good response.Run these in 1/16 Revo and 1/16 Summit.
Strong enough to rock craw.
Drives fine underwater even in the ocean.
Powers 1/10th truck tires in tall grass and deep sand.
5+ years before I had one died and Blue Bird repaired it for me for free.
Great customer service!This is a great servo replacement for my traxxas 1/16 summit. It has more torque and is also waterproof. I have been using this servo for quite some time with great results I would recommend to anyone looking for a micro servo.Best replacement for my son's 1/16 servo. Had it installed for almost a year with no issues. Stock horn fits as well.I use these in my 1-lb fighting robot to actuate a claw. They stall out for long periods at 7.4 volts but still last a long time. I've burnt out a few, but never stripped a gear. Very well made.awesome in my 1/12 pan carOverall a great little servo, takes the abuse and just keeps on trucking. Best bang for buck metal geared servo on the market. If anyone has a good idea on a bit more waterproofing I'm all ears. Taken it through a few lite puddles but nothing to deep, just would like a little more assurance. I would very much recommend this product I've been out bashing for a couple of months regularly. The servo is solid and far more responsive than the last. It's a little louder but that's to be expected i think when you have metal gearing over plastic.Na tieto serva sa tem pouijem do FSR V 7,5 dfam e parametre bud zodpovedat deklarovanm.Perfect fit on mini revo, lots of torque, has lasted a whole winter as waterproof, deecent price too.
