I'm still trying to rap my head around that MGP what does ti do . sh dent there be a needle valve on that side of the carburetor
MGP = Governor + Mixture control. The other side (not pictured) of the motor is the throttle servo and carb lever. You are looking at the mixture side and the servo pictured is connected to the high rpm needle. Temp sensor mounted to the head, so the MGP goes rich or lean based on actual engine temp keeping whatever temp you set as the target.

MGP useless dead weight to carry on a helicopter. Better off learning to tune a motor properly than relying on electronics to.

Wow, who took a leak in your sandbox! You're entitled to your opinion and I respect your experience and wisdom.

MGP is a governor/rev limiter first... So it's hardly dead weight since most use external gov's or rev limiters. The mixture portion adds one wire, one 10g servo and a link. Let's assume that's 20g total. Pretty small percentage of overall weight, IMO.

I completely agree that it's important to learn how to tune an engine by ear, but that comes with time and experience. Just because I'm not physically adjusting the needle, that doesn't mean I'm not learning how a properly tuned engine sounds and "feels".

Personally, I don't believe engine tuning is static. The engine benefit from different mixture percentages depending on how you're flying. Tuning by temperature (egt would be best, but this is just head temp) allows for the greatest level of consistency without compromise. It's also nice if the system can recognise a problem (pipe loose, head loose, glow plug loose, etc) and richen the engine to prevent damage...

Lastly, at 20+ bucks a gallon, I believe the extra possible "fuel economy" will pay for itself in the long run.

So there you have it folks, 2 different opinions to choose from. Traditional or Techno, you make the call!

Just buy a computor controlled fuel injected os engine and run the o2 sensor on the exhaust so the controller can properly tune it and there you go, The age of modern day technology

those mixture controls are a pita to setup. Pita to install sensor. And from what i here they break with the engine vibration. I have a CSM carp smart if anyone wants to try one. $20 and its yours. I dont trust them...

Naaa, not until they add a turbo to it...

Carbsmart seems to have a bigger following of haters than MGP. Going full lean during start up is a minus and charging 10 bucks for a 15 cent thermister chip doesn't help either.

Setup is a breeze with MGP, but he sensor install is a "commitment"...

Sounds like everyone's a little grumpy, so here's a humorous story from Friday. More nitro learnings from Speedvision. Unfortunately, Tom and Steve werern't there to enjoy it, again...

I was "flying" the Velo 50 on Friday and it was pretty windy, so I had my hands full. Was getting the MGP dialed in and thought the engine was a little down on power. Decided to finish the tank and about 30 seconds later - POW - follow by silence, had to do about a 30' auto (only my 3rd) and settled softly to the ground. Problem - glow plug must have been loose and she ran till the plug popped completely out...dangling by the remote glow driver. Put the plug back in and ran 2 more tanks.

As long as I'm having fun, who gives a rip, right...

No, but yes on Wednesday, weather permitting... Might burn a few batteries at Fallasburg park in Lowell, though. They're E-friendly over there. Nice big area too.
