Flood Damage/Ground Up Rebuild

[Roboteernat]

Sorry to hear about your situation, hope things are sorted timely for you.

Regarding beetle components, people commonly stick with those 22mm planetry gearboxes and either fit some 1806 brushless motors to them by swapping out the shafts/soldering on pinions and using some programmed brushless escs for forward/back. (https://www.instructables.com/5-Minu...leweight-Comb/) The brushed people use the 180 sized motors, such as FK180-SH or PG22-180 as a combo, about 16000rpm motors, something else about silverspark brand of these, or even nerf gun motors are commonly mentioned. There is a cad model lineup of current motors people use that is rather handy: https://grabcad.com/library/popular-...9k6Z1YMGlBk99Q

ESCs tend to be reprogrammed brushless esc's running BLHeli (or simon K) and using the blheli programming software, its simple to ammend the program running to have brake, reverse and set points.
Brushed motors tend to also use brushless escs, that run custom opensource firmware and only use 2 outputs to connect the motor to. DM me for links?

The water damage to the PCB, if its not severe could be saved using some rice, and time... that is still an option. The motors may have died, but save the gearboxes as they could ell be saved. 22mm gearboxes tend to have a plastic stage in them so you need to buy 2 to get a full set of metal gears, so that may well be a saving for you as they tend to be sealed and greased.

Servos, have a look on the beetleweight combat facebook pages for current devs, but also people - like myself, use 37mm gear motors for lifters as an option with a reprogrammed ESC.

Several companies now sell premade brushless gearboxes for beetles, and brushed, OWObotics, https://www.owobotics.com/, Just Cuz robotics https://justcuzrobotics.com/shop, TeamBTR https://shop.teambtr.com/product/bil...weight-gearbox, Bristol Bot Builders, https://bristolbotbuilders.com/parts.html#beetleweight and a few others i cant remember off top of my head including a new one that opened up. (i do featherweight stuff mostly - www.teamsc.co.uk)
