I have always used the "feel" of the fastener to set the torque value.. THere are soo many dissimilar materials on a heli so it is hard to use a specified toque value.. Some of that chinese aluminum will pull threads long before the screw would reach torque value.. Some screws that pass through grommets and eyelets would be ruined with a specified torque as well..

I suppose someone with lots of patience could use a torque wrench but if they were really wanting to be anal on it they would be using specified bolt stretch as the measure rather than torque value for that is what the torque value is attempting to achieve...

If in doubt lean it out . We don't do this to save money, we save money to do this

the whole idea is to set the torque below what the fastener will stretch at. You don't need to twist a fastener, only prevent from stripping the head/tool or snapping a bolt at least.

Anyone work with "Torx" head fasteners? Are they stronger than Allen hex head? I see them on cell phones all the time. Stronger for smaller sizes.

one more thing, when someone refers to a bolt or screw as being SNUG, is the bolt
A, SNUGGIE POO?
B, Snuggums?
C, SOFT AND SNUGGIE?
D, SNUGGIE WUGGIE?
E, SNUG but not TIGHT?
F, SNUGGLY?
G, SO DAMN SNUG IT MIGHT AS WELL BE TIGHT? or,
Golly, it's So Damn SNUG YOU HAVE TO PRY IT OFF with something?

I have a torque wrench but rarely use it (any more). Why do I have a $100.00 tool that I don't use, you ask? Because I used to use it religiously for a while and over time, I calibrated my wrist for how tight is tight. If you snug 5,000 3mm fasteners in your life, you may find that a torque wrench helps on the first 2,000 but is increasing less valuable on the next 3,000. Yea I know. Some would have figured it out sooner.

Something I did learn when I started using a wrench is what Ben suggested. When my torque wrench was new, I was surprised at how little torque the recommended value was. Before owning a torque wrench, as a kid, I learned how to strip the shizzel out almost every screw I touched. I'd put a screw in and turn until it got tight - and keep turning until it got loose again. Over more time I learned to apply slightly less torque so the screw didn't strip. Well, the torque wrench taught me that slightly less, was more than recommended.

If you don't own a small screw torque wrench and don't want to buy one, see if you can borrow a friends. You might learn something.

That is very true.

But I also feel that for many of our mixed materials, with unknown strength of the bolt, the plate it is going through, and the nut, it would be best if the kit maker could provide the torque settings for those who would want to use them.

Another early lesson the torque wrench taught was that the correct torque for a 5mm long x M3 machine screw into steel was not a good choice for a nylon cooling shroud.

Its always that last turn. If you ask yourself "should I tighten more ? then don't your good . Most metals expand and contract with temp changes so snug and 1/4 usually is good .

I stole it ,flew it and gave it back ;)
