I'd rather pee on an electric fence. Than strap a heli down, and spool it up.

Remember when i was in my very early teens,being young,curious,sadistic maybe,encouraging a friend to try this to see what happened.He reported that it did kick a bit,sorry Gordon

I have seen top F3C pilots do it at the 1st world air games in Ankara, Turkey. One guy holds the heli from the landing skids with both hands high above his head and the other adjusts the needle. They were from a far east country. Could be Korea or China.

I run in my new Zenoah heli motor with a 12x6 propeller with prop adapter from hobbyshop. I had to fabricate a motor mount from wood. I enjoyed it, cause it gives you a very good feeling of properly adjusting H and L needle valves

Next time I needed a new motor I did this. I put it on the heli. I removed the main and tail rotor. We have work tables with wire mesh tops at out flying field. I cable tied the heli on the mesh. Then, did the initial running in process for almost 2 tanks. Then I put the main and tail rotor back on and went flying. I thought this was a good method too

mounting my nitro helicopter on top of a ladder to tune the motor
Doesn't an act like this start out with the words, "Hey Bubba,,,, hold my beer."

Or as Jeff F. would say, "You might be a Redneck if you tie your heli to a ladder to tune it."

Just for fun, I might add that when I started flying helicopters in 1989, it was suggested that you test run and breakin your engine on a test stand (with prop installed) until it would idle reliably. Ringed engines were not as common then and needed to be "broken in", but even now it still applies to an extent. basically, we need to know that it will not die at an idle, and that it is not running lean.

I test run mine now with no blades installed (in helicopter). Still have the spinning paddles, but at least it will not get off the ground, and it makes it approachable for tuning (with extreme caution). If you're in the build process, you can even leave the flybar off the head for more safety. Do note that once blades are installed, it will likely need to be a bit richer to compensate for the added load, but you get the same "run in" effect, and can get a feel for your engine.

Also, do not assume that just because your engine will not idle reliably that it is too rich. It may be too lean. I ALWAYS try going richer first. Too rich won't kill (as in destroy) an engine. I still like to run a couple of tanks through before even attempting a hover.

My method of tuning is to richen it until it wants to die, then go lean until it wants to die. Set it just over halfway in between. Apply this method both to the low and the high side. If you have mid, it will adjust accordingly once the high and low are set. Better to er on the rich side. All info I have states that these glow motors will produce more power on the rich side. Just need to find the sweet spot so that it will not load up and die.

Good luck!

When you are on the ladder and the thing is winding up in Idle 2, yell out: "Darwin ain't got nothing on me!"

On another note, why not just fly the damn thing and tune it as needed?

its amazing what the lack of education can do for one. Long ago in a land far far away (actually across town 10 years ago), I bought a jr ergo 60, set it up (99% sure that the setup wasn't even close) and flew it (ok, hovered it in the rotorwash until it got uncontrollable and set it back down). my only other rc experience was with rc cars and how you shut an rc car down. Looking back, I really wish someone would have gotten a picture of my dumb ass laying on my back shimmying under the rotor disk to pinch a fuel line.

I'll take the darwin now.

don't knock peeing on an electric fence til you've tried it!!!
My cousins did that to me when I first moved to the country and I've never liked electricity since then.

When I was 15 or 16 all the younger guys my age or so worked on a farm here.One day while putting up hay one of the older guys(19 or 20)brought some cold beer for after the work.
Well after a few beers I of course needed to sneak around behind the barn and take a leak.

WOW!!!!
I had no idea that wooden fence had an electric fence wire around the bottom to keep the pigs from rooting under it.
It was like getting kicked in the crotch from the inside out.lol....

This confuses me.

Why put it on a ladder, much less tie it down?

Is the air that much thinner several feet up?

Perhaps if the guy said "Tie it to a wall next to a window to adjust it's vertical flight performance characteristics" I wouldn't look at the guy like his brain was on fire.

But the ladder? LOL! I have a mental picture of a helicopter hovering around with a ladder attached to it.

Sure would be funny!

I imagine the point of having a ladder is to get the helicopter out of ground effect. In fact, the ground effect is probably a big contributor to the resonance problems described above.

On a small electric helicopter with high headspeed, there's not much risk of resonance-- the vibration patterns are nowhere near the mode of the frame materials. I strap my T Rex 250 to a little lazy-susan to adjust the tail servo, no problem, with or without the ground effect.
