i'm not sure if this transfers over, but never know! I'm using the Castle governer and i programed my RPM at 1950. After flying it changed it to 1957. I thought that was pretty wierd but i learned that it is perfectly normal and that everyone gets these results. Again i'm not sure if it's the same thing for the different governor but it could be a possibility

I use multigovs in my velocity and 700N...I have noticed the actual readings are slightly different then what is set in the multigov when the engine is not in tune. First make sure you did set the gear ratio properly and then try richening up your engine a little. You could just be too lean.Dave V.

i recieved my results in an electric helicopter (but still a 700 sized). I heard from several people using the same helicopter and other electrics that this little difference in the reading is normal for all helicopters and it shouldn't actually affect your flight. I mean, if you programeed 1800, and you got something like 1920 in the log, then i'd be worried about something like gearing imputs. That being said, if you have a nitro, VANHELI might be right about motor tuning, because my log only read 3-7 HS off what i programmed.

Hi Guys

Yes it is not a big issue, but it should be a lot closer than that......

If it is actually holding a governed rpm, but just off by a bit, i bet it is your assigned rear ratio.

Regards
Paul

+3 on the gear ratio is the fix, i have multigov's on all my heli's and they all tach within 5/10 rpm of where i have them set.

First, 30 rpm is not an issue.

Second, who is to say that the multigov is off?

Did you ever think that maybe, just maybe the tack is off?

The question is.... "is it holding"?

I'm with Zane here, it may not be off, but even if it is don't worry about the 30 RPM differenc, or just lower the setting,,

to add, if you calculate your gear ratio (with a calculator) you will probably come up with an 8 or 10 digit number/ where your Multigov only uses a 4 digit number, see where I'm going there
