vbar govenor help

[norman]

can anyone help we have set up a v bar 5.3 on my t rex600 nitro and all works well we have tryed to set up the govenor but it will not work in the air on the bench it it ramps out in idle up 1 and 2 we even run a starter on the engine so it thinks the engine is running and it ramps up but when hellie is in the air it like going in to hold

my transmitter is a spektrem 18 qq so any help please

Have you got V curves for the throttle in IDL ups....

[norman]

Yes I have it works fine on the bench we put the starter on the motor and spun it over and it works. Fine it only when in the air it's if it going into hold so I didn't no why

[jwatts007]

If you spin it with the starter and you see the revs going up isnt that just telling you that the sensor is working...you must have your channels set wrong have you checked in the transmitter section of the set up that everything is working correctly...

Hi john thanks for that on the bench it all works ok in the right direction but it the air it's like it rev it self and I ant got a clue why

[tonystevens]

you have to spool up in idle 1 i found, have you tried that?

I have normal mode, highest point of the throttle curve is 48% so ungoverned. Once up to speed I flick into either idle 1 or 2 which must have a straight throttle curve of above 50%, v curves won't be governed.

I was having trouble with the governor and gave up in the end and went back to the align governor a lot simpler. I would have liked to get the Vbar governor but it was a bit too complicated maybe I'll try again one day

Step by step instructions how to set up the vbar gov in combined mode, very straight forward really.

Thanks for your help I will try this on SaturdaySaturday

Ok it's Saturday we have again tried the vbar with different set up and it's still the same
on the bench in gov mode works fine throttle working to 100%
start up engine and it only opens to about 25% why ???
i have a align sensor and rev the red and black wires the magnets are in the fan one + and one -
has anyone got any idea apart from selling it and go back to planks

Maybe a wild guess for me as I have never setup a vbar on a nitro but mostly on electrics. Check the end point adjustment of the throttle servo, make sure it throws both sides.

Put it on the floor flick it into throttle hold and back out. I've seen it before on two other helis. Also don't forget to flick idle 1 before lift off to engage.

you wont get it to spool up in normal mode, i cant tell you why but you have to flick into idle 1 and then gov will kick in and spool up fully. Never managed to overcome this and i know others are doing the same. just take off in idle 1 problem solved.

This may well explain my issues that i've had with the gov not seeming to engage even though all seems as it should in the set up although i've been able to spool up in normal mode before on other models set up in the same way. My normal mode levels off at 1/2 stick at 48%, once at 1/2 stick i'd flick into idle up and that always worked before but will try what you're saying Tony.
