Lockout/Brownout Problems - Static is a #1 issue

[Grimmy]

So I am waiting for some building parts to continue assembling my trex500, and have been trying to read through the pages of this thread. After many headaches from reading so much, I can't keep straight what I've all read.

I understand connecting the boom to the main drive bearings, and the same in the tail. Should I use a wire and connect the whole thing to the main shaft bearings as well?

I did order some different bearing holders, some metal ones, in anticipation that I should have continuity through all of these parts.

Just need confirmation. Thanks.

HobbyKing have a metal tail boom holder for 11$ to the T-rex 500, thats will make grounding easy.

I have a problem with this title lol! Older DSM is unquestionably the number 1 brown out issues lol!!

its so easier then you think and cost not a dime to fix this issue ..


take a wire about 4 inchs long ... sstrip one end and put it between boom and the stab wing brace..

take other end strip it 1/4 inch

zip tie to boom supports so the rest of the wire loops down and hangs downward
done deal ..

this is done on real airplanes all the time as in the glass tubes with the wire inside for lighting strikes .. and such

it works great ..

Number one may be drawing more amps than your bec will pute out.Ive never had any static problems with my belt driven heli running spektrum but I also take a q tip and oil my belt with cylicone base oil.If you are running high demanding servos and a heavy pitch set up especially if running an fbl unit imo its a good ideal to run a capacitor to hold more amps.This is a known problem with the 500 size.CC makes an add on capacitor and I also seen some on ready hly.

I just drug out my EXI 500 CF/Metal version to finish it up and get her in the air finally. Because I haven't done anything with a heli in quite a long time I've been doing a lot of reading. Ran across some posts on static with belt drive birds again. I went ahead and grounded my Beam 450 back when I built it a few years ago but never really checked for static beforehand. Now I've seen a few videos using voltage detection pens. I got out my Fluke VoltAlert pen and ran it over the entire EXI 500 while spun up (without blades). No indication of any voltage anywhere EXCEPT the main gears and a smaller amount at ESC output and the motor. The pen lights up solid and bright at the gears only. Kinda hard to ground the plastic. I'm guessing the static buildup is due to wind friction. I guess a thin brass strip could be set up to rub the gear and ground it to the bearing block. Now to be fair I have to say my Fluke is the 90-600volt version. There are some out there that read as low as 20 volts. It would be interesting to know what rating the tool had that was used in the videos. I don't have any issues with brown out during bench tests but you never know. She hasn't been in the air yet. Anyone else seen this gear static phenomenon?
