GV1 Mixture Servo Setup

[contact303]

Really BAD wheather today so I finally get around to play with a mixture servo to use the GV 1 to its full potential ...
Really I have the engine setup right and it flys well
Smokes like hell and I can pitch pump all day long ..
So all is well ...time to try the mixture thingy :O)

I looked this up and found the perfect setup for the sceadu
I will use a HS81 and have also found a nice place to mount it .
I have my DX7 setup for 3 flight modes so Normal ( No GOV) - IDle 1 (gov1750 ) - Idle 2 (gov 1900)

So where i do need some help is the setup menu of the Gv1 regarding mixture settings ..
The manual is very unclear and/or badly translated or indeed its the third possiblilty ..me beeing to dumb :O)
Anyway I marked the carb with a Permanent pen to show position where i fly wiht I guess that has to be the 50% value ??? Does it ??
This position is about 2 3/8 turn out from closed carb.

What i do now in the Gv1 menu?
I did set the MXMD to GOV
TX set to NORMAL on the GV1 the menu MG1 is at 0% and MG9 at 99%
Now i guess thats wrong because it moves the servo in normal mode (gov off) very far to the left (richer) ??
TX set to IDLE 1 (gov ON) the menu shows at thorttle -100% now point MG8 at -74% ?
This moves somewhat according to throttle imput ..but i dont understand how to set this up ...
I have the point reference I am flying with . So really where do i need to plug this number into the equasion here ?

Also i dont understand, when u add throttle ergo add pitch which way should the carb be moved ?
right(leaner) or left (richer) ??

Ahh well
Any ideas greatly appreciated
Really 1st thing i need to figure out :
Whhich way aroudnt eh servo has to turn when GV1 is active ..

when I moving throttle to 100% the servo moves the Carb to the left (richer)
Does this sound correct ???

I watched all of finless vids on GV1 but hew never touches the mixture function ..

Is there noone that has done a setup with the mixture function ??

I've tinkered with, and seen a lot of GV1's over the years and I have never seen one setup for mixture control.

WOW ..never ? :(

And i just got the setup all nice with a HS81 and a DIY Carb servo arm .....
Well ...I ll try around with it then

But what about direction
It would be good to start with the servo the right direction ..
So wjat do u think ...What should the servo do ..when u move Throttle up ? Should it go leaner or richer ?

I wouldnt bother with the mixture function on the GV-1. Just get a Carbsmart instead. The GV-1 is very difficult to set up as a mixture control device and also cant measure engine temperature the way the Carbsmart can. Carbsmart technology wasnt widely avaliable when the GV-1 was designed.

I have them both and run them together.

right well iam trying it ..
I will greatly reduce the ATV then i will have the 1st 4 MG point at the same value and move Carb a little Leaner (to the right) a when full pitch/throttle is given ..
See how that goes ...
I really want no big changes aim just tinkering for the fun of it ..
1st Pic Throttle idle
2nd Pic Throttle Full

Umm...what did you mount that servo with?

[contact303]

YEP glued and Hot gunned down
This is not gonna come loose if that what you worried about
The servo does not need any power hence i dont see a problem with it ..I can pick the heli up by this servo

Right on. I'd be a little concerned as with the clicky thing on the needle, the screw does turn easily (like you mentioned), but if the hot glue is affected by fuel or constant vibration and falls off...well I hope you can auto.

Tinkering with electronics can be a lot of fun...until it ends up costing much more than you're expecting.
