Twin set up

[John Beardslee]

Tie them both together with push rods with one servo or two servo with a Y harness. Make sure your servo connection are very tight, no slop. You will find that after you are close with both motors on mixture the right motor will need to be a little richer than the left. You can hear the right motor running a little more load making it a leaner. A 1/8 to 1/4 turn out on the right needle will bring them both together or maybe a little more whatever is needed.

On my SST twin I've added a JR product called a "Match Box" it is a servo synchronizer that I've used for many years in my giant scale planes that had multiple servos on control surfaces. I used it to match the 2 servos that control the individual needles so that each flows (Boris Flow meter) the same as I increase or decrease the 3rd channel mixture control. The match box is really small, easy to use and compatible with all servos and radio systems.

Thanks, John

Not to hijack the thread but I solved my fried servo problem by using the setup Julian has for throttle

when my finger is tight against the stop there is enough flex in the linkage to keep servos alive

no problems since going to golden rod type linkage, which then will maybe get comment about setting linkage to not go hard up against servo limit

you go your way i go mine

Using the plastic rods is better on the servos for sure. If you give it to much it will flex saving your servo also when your taking engines in and out they can be moved easily out of the way.

This is why the radios nowadays have EPA settings. You can program it to stop where ever you like. So no crashing into the stop and over working the servo.

That and modifying carbs into spinners with no bump stop. Mark Bullard does a great job with this using peek material for the barrel.

Exactly what I was thinking..and also if you say there is give to save the servo then there is going to be give when you running wide open and the boat is jumping around. Anther thing use metal gear servos for throttles and set the epa correct what 15 bucks more for a metal gear for a 3k plus boat. Just my opinion.

With that said sometimes the radio glitches and goes crazy it's happen to me before. If you have metal rods that's a problem. With the plastic you have no issue as it gives metal don't.
