January 14, 20169 yr If you want a technical project, go with coupling motors and using geartrains. Make sure you can disassemble the vehicle quickly to replace broken gears. If you want to build a fun powerful vehicle quickly, simply use one motor per wheel, and eliminate as much gearing as possible (including differentials, which aren't needed in this configuration).
January 14, 20169 yr Oracid, Try Sariels' book "The unofficial Lego Technic builder's guide" http://sariel.pl/2012/06/my-book-available-now/ I found it quite easy to follow :)

January 14, 20169 yr Speaking of hard coupling motors and the chance of breaking the gears, has anyone broken the internal gearing on any motor?
January 14, 20169 yr Author Speaking of hard coupling motors and the chance of breaking the gears, has anyone broken the internal gearing on any motor? YES, I HAVE , but with old motors styles, not the PF ones. Edited January 14, 20169 yr by ARXD
January 15, 20169 yr Speaking of hard coupling motors and the chance of breaking the gears, has anyone broken the internal gearing on any motor? I didn't break any internal gears but something must have worn down internally after prolonged use. I took the M-motor apart and the motor ran quieter without the internal gears attached.
July 23, 20204 yr I've built an RC vehicle with 1 L-motor for propulsion and it isn't moving as fast as I wish it did. Will it move significantly faster, if I add another L-motor?

Will it move significantly faster, if I add another L-motor? Depends. If the single L motor is being slowed down significantly by the weight of the vehicle, then yes. If not, then probably no. In either case, it will accelerate quicker with two motors than with one. Other ways to make it quicker: change the gearing, get the Chinese extra power motors, get a buwizz for increased voltage = more rpm.

Other ways to make it quicker: change the gearing, get the Chinese extra power motors, get a buwizz for increased voltage = more rpm. There is 1.4:1 gear ratio and I believe it is slowed down by the weight. Also will a power brick feed a one more L-motor? (Now there are already L, M and M connected).
July 23, 20204 yr Just now, Parazels said: There is 1.4:1 gear ratio and I believe it is slowed down by the weight. Also will a power brick feed a one more L-motor? (Now there are already L, M and M connected). If the weight is the problem then yes an extra motor will help. There's a limit to how much power one battery can put out. What exact components do you have for battery and RC? if IR receiver, V1 or V2? Do all the motors have to turn (under a load) at the same time? Edited July 23, 20204 yr by amorti

Right now I use: 1 IR receiver V2 1 L-motor 2 M-motors Most of the time all three motors must work simultaneously. And now we are discussing about plugging in 4th motor...
