I'm trying to get my old concept 60 running right i.e. mixture wise I seem
to get it running ok then next time out it as though I have to start again
messing with the mixture to stop it from over smoking and losing power then
next minute its hardly any smoke etc. What I'm asking is it worth investing
in head loaders to try and set the mixture right on the ground ? bearing in
mind I'm not a top flyer just hovering about learning new moves etc.

Regards

Bob

I'm a newbie at this, but I bought a set for my V2 Raptor 30, and it does
make life easy, and very safe, setting up the engine and controls in the
live situation. I clamp the heli to the patio picnic table so that vibration
doesn't move it around.

If you're having that much trouble with the mixture then chances are there
is a reason for it. Check all your plumbing (clunk lines, fuel lines,
muffler pressure line) and also check your muffler for leaks.

A heli engine that's set up right shouldn't need more than one or two clicks
on the main needle every now and then to get the mixture right. If you're
chasing it all over the place then something is wrong.

I don't believe in using head loaders. Just up for a quick flight, then
back to adjust.

That's not always that easy for someone who's new to Heli setup. In my
experience you should do whatever gives you more confidence and if head
loaders do it for you then you should use them.

I have to say that headloaders can be a very good thing. Granted they're not
the be all and end all of setting up a motor, but they get you close enough
to optimum that a newbi flyer wouldn't have motors quitting while they learn
to hover, and for the more experienced, they get you close enough that only
small adjustments are necessary.

Of course, that's always supposing you don't rev them so hard they turn
inside out. That's a scrotum shrinker if ever there was:-)
