Ok, so how much tork is enough to turn an 1/8th scale? I don't want to spend $100.00 on a servo if I don't have to.
I guess the same question would apply to the speed of the servo as well.
Also, how small (low tork) can you go for the throttle and 3rd channel servos?
Hi Doug,
The Futaba 9350 is a great rudder servo and it is a $100 unfortunatly. They are a digital, coreless, dual ball bearing, metal gear water resistent unit that also has metal heat sink plates in it and heavy gauge wiring. It has 111 oz. of torque at 4.8 volts and 130 oz. of torque at 6.0 volts. It has all the speed you need. If you have a gonzo sized turn fin you may have to even slow it down with the TX set up to keep the boat from coming around too fast and making 90 degree turns. It also comes in s standard size case. I've never had one blow up on me yet.
I agree with Mike that the radio gear is not the place to scrimp. I send all of my stuff (tx, Rx and servos) back to Hobby Services every year. It usually costs me a $60-$100 but the piece of mind is worth it. I also replace my RX switch in every boat every season with a new one. You can't see if there is any corrosion inside the switch housing or contacts and if it goes bad on the water, your failsafes won't work and there goes your baby into the beach at 60mph.
Are you going to make it out this year for a race? I know you've been working on some new stuff.
Let me know if I can help.
