Need more smoke!
It works well but I would like more smoke. I bought some GITANKSOMERS and will try one of those. The Henlong unit is meant for 1/16 scale tanks so the smoke tank is small. The flash unit is hard to see with daylight and the masking tape I used to secure it to the smoke tube should probably be painted black. Also the smoke tube should sit a little further back in the barrel so when it comes out it's already spread out and should look more realistic.
I also need to change the mount. I 3D printed the base but the tank gets so hot the base has warped!
The toggle switch is to shut off power to the smoke unit if I'm not planning on using it. I wired a cheap digital meter that shows the voltage to the smoke unit, mostly for troubleshooting purposes in case it stops working. The little PCB is an RC switch, I fire the canon from a toggle switch that is channel 5 on the transmitter. Very simple hookup and works great.
