Hi
Should the govenor sensor be placed on the left (muffler) side or the right side?
Any pro's or con's?
(R50 titan and OS 50 hyper with Multigov)

Hmmmm I don't recall ever seeing anything about this. I would think it wouldn't matter, other than maybe put it where the wiring won't interfere with anything or be in your way.

It doesn't matter, whatever is easiest for wire routing.

Thanks, one thing less to worry about.

Hi
The sensor ended up on the right side. Easiest for wire routing and adjustments.
The Multigov fitted perfect, was easy to setup and it is working excellent for my type of flying.
My settings at the moment is:
Normal - 1800 - Full gov
Idle 1 - 2000 - Full gov
Idle 2 - 2050 - Limiter mode

I have the Multigov also but I have mine set up
Normal - 1800 - Limit
Idle 1 - 1900 - Full
Idle 2 - 2000 - Full
The normal is set as limit to make landing a bit easier with out the engine screeming.
Idle 2, with the OS hyper 50 with a gear ratio of 8.5:1, The optimum power is obtained at 2000 rpm head speed. Thats 17000 optimum engine rpm. I think I found this info in an issue of RC Heli magazine.
One thing that I made a mistake on and was pointed out at a recent fly in. When I set up the Multigov low and high throttle setting, for low I had the throttle on the transmitter all the way down and high, all the way up. For low this was wrong. Set your low at apx 2/3 stick. This way when the governor senses the rpm are to high, it does not drop the throttle to low and have to recover in the event of, say a tick tock, where the load is constantly changing.

Good point!

Is this a better way than icreasing the LowThrotPcent setting?

I've seen somewhere that you might get slightly moore power when the head speed drops down (from 2050) to optimum (2000) rather than from optimum.

about the low throttle setting, I think we are talking about the same thing. When I originaly set up the governor, where you set the high and low throttle I had a linear throttle curve and set the low with the throttle all the way down (idle), and I recently found out that was wrong, the low point should be set as if you had a "V" curve and you set the low throttle as if at the bottom of the V. Now these are setting actualy in the governor.
about the optimum rpm, 2000 2050, what gets you / keeps you in the power band, I dont know.

Thanks for sharing, vandelescrow!
Good speed!
I suggest installing it on the opposite side of the muffler. You want to avoid soaking it with exhaust oil, and if it has a led ( zero alpha) you might not see it behind the muffler. I´m not sure but probably it´s better for it not having extra heat from the muffler close to it .
