Only if the battery is fully charged, leak a few volts and it'll be fine.......

Coloured smoke....

Hmmm... saw someone with a red smoke-bomb on a quad in Steele's recent video and I remembered. "I can make those!"
I have all the chems left over from my days in amateur rocketry which form an active component in smoke....

Probably not a great thing to use on a hot, dry day.

Might be worth a little experimentation.  :evil

I am more than willing to strap a smoking canister to my quad if you're looking for guinea pigs ...

Can make them any size. I usually make a custom 'paper' tube from card and PVA. Strong enough to withstand motor pressures and relatively fire retardant.

Though things HAVE improved since my FIRST attempt at rocket motors:




latest firing was a bit more PRO...

Easier method.... Plumbers flue test bomb.

You can get em online on eBay at a push but the lower quality ones take a fair bit of heat to get going well while the proper decent ones like Rothenberrger brand kick off with something as small as a spark coil from a lighter... Plus when I used to use them they came in white, red, green and a weird pink colour.

Doubt it'd be to hard to rig up a glow coil lighter triggered by a servo as a midair igniter :whistling:

AndyRC had a go at this a while back. It seems a quad makes way too much turbulence and the smoke gets spread so thinly that it's hardly visible. I reckon that if it's feasible to pipe the smoke out 6" behind the quads blades it could stay dense enough to be effective though, Or possibly some sort of "H" shaped frame to hold a pair of smoke grenade out either side of the quad would get them into calmer air?
I need a pay rise........ Though I'd settle for a reduction in the amount of hours I need to work to get the same money.

Andy7

Yeah, I think you may be right. Could be worth mounting the pyro on a stick so it's behind a little way.
I'd need to use an inhibitor in the mix to slow the burn down too.

Surely the same is true of helicopters and yet:



Reman

How about trebling the tubes length but packing it with a nozzle a quarter of the way in from both ends? You could mount it sideways to blow the smoke our either side, but shielded till far enough out of the propwash to catch smoother air, and if the charge burned evenly it would keep the center of mass reasonably central too.

How about 50grams of ammonium triiodide between the smoke bomb and the quad body?
