Need Servo Advice
« on: July 12, 2007, 10:47:08 AM »
For continuous rotation I always use HS-311 since they are cheap and good quality, but now I need them for a competition where strength and speed will be determining factors, so which ones you recommend?

They must be easy to modify or already modified and have better torque/speed than hs-311 and also "cheap" (of course, they will be more expensive than hs-311 but I don't want to buy $100 digital servos)

I was thinking of HS-225MG

because they have to be waterproof and I don't have time to waterproof a gearhead motor.

Thanks for the tip but I already know how to modify servos. The thing I need are stronger/faster servos that arenīt too expensive and can be modified without much difficulty (some servos are very hard to modify).

I own four HS-225MG's. They are a bit expensive, but I really like them :)

Most of my robots use them, including my Stampy robot.

Using same weight and same wheel ratio, how fast they are compared to hs-311?
