Tug Posted April 20, 2019 Share Posted April 20, 2019 Is that from the indestructible Russian body company? 3mm sounds bonkers? Quote Link to comment Share on other sites More sharing options...
.AJ. Posted April 20, 2019 Share Posted April 20, 2019 Yep, I’m guessing 3mm is the starting thickness before it’s moulded 1 Quote Link to comment Share on other sites More sharing options...
bodgemonkey Posted May 9, 2019 Share Posted May 9, 2019 Been looking at picking one of these up for a while now, now that it looks like upgrades are being released it looks like I may have to bite the bullet although I keep chopping between this and a trx4 1 Quote Link to comment Share on other sites More sharing options...

willb Posted November 30, 2019 Share Posted November 30, 2019 Hi all, how do you fit the Turnigy 6S packs in the UDR? I have the Heavy Duty packs and they’re at least 3mm too wide.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Honeybadger Posted December 21, 2019 Share Posted December 21, 2019 What gearing do people use for 4s? Would a higher kv motor suit it better? Or would 6s and lower kv be the way to go? Quote Link to comment Share on other sites More sharing options...

Honeybadger Posted December 22, 2019 Share Posted December 22, 2019 I'm just aware that the standard setup is a compromise to run both 4 & 6s and I'm interested in a good setup for one or the other that won't stress the esc more than necessary.

Tug Posted December 23, 2019 Share Posted December 23, 2019 You could look for a motor in the 1500 to 1800 range and gear it accordingly, but that would be slow on 4S, not a problem if you're only running 6S. 1 Quote Link to comment Share on other sites More sharing options...
Kukynas Posted December 23, 2019 Share Posted December 23, 2019 I think that car is heavy for 4S plus you’ll increase run time on 6S and your electronics including battery last longer due to lower amps drain, if you can fit decent size 6S pack go for it and buy motor with adequate kv, you can always tweak the speed vs torque later with different pinion size 1 Quote Link to comment Share on other sites More sharing options...
Honeybadger Posted December 23, 2019 Share Posted December 23, 2019 It is pretty heavy, has quite a few upgrades and stainless steel skidplates. I've had a quick go with 4s as it is and wasn't particularly impressed so I think I'll go 6s and buy an appropriate lower kv motor. 1 Quote Link to comment Share on other sites More sharing options...
Kukynas Posted December 23, 2019 Share Posted December 23, 2019 4082 can would be appropriate for such car if lenght isn’t an issue, XTI 4082 with 2000kv would be my pick or similar motor capable of 27-30V, you could go lower kv (capable of more volts) but you’ll loose efficiency Quote Link to comment Share on other sites More sharing options...
Tug Posted December 23, 2019 Share Posted December 23, 2019 Lowering kv improves efficiency, not the other way around. There's a guy on YouTube running a very long can, something around 100mm in length, so you can easily swap to a longer can. Quote Link to comment Share on other sites More sharing options...
Kukynas Posted December 23, 2019 Share Posted December 23, 2019 Yes, if you use adequate voltage of the motor, if you use i.e. motor capable of 8S (33v) only with 6S (25v) the remaining power is lost so it doesn’t operate at its maximum efficiency hence suggestion to use motor with closest voltage allowance no matter what kv is stated Quote Link to comment Share on other sites More sharing options...
Tug Posted December 23, 2019 Share Posted December 23, 2019 Pretty sure they don't work that way. Whatever voltage you offer a motor will determine how much power it consumes. Either way, dropping the kv and upping the voltage will result in near stock speeds, but with less current being drawn. Quote Link to comment Share on other sites More sharing options...
Kukynas Posted December 23, 2019 Share Posted December 23, 2019 Precisely, and I’m pretty sure we are both talking about same thing but in slightly different scenarious, lets take 2 same size motors with different kv, one with max voltage of 25v and second with 33v first one with 2000kv on 6S producing 50k rpm second motor with 1600kv on 6S producing 40k rpm so to get to the same spur rpm we need to up the pinion tooth but as a side effect motor will see higher load means start to ask for more current coz there is not enough voltage anymore to get to the same power = V x A and as a second side effect start generating heat because it doesn’t operates efficiently so to get max effieciency of our motor we need to choose the one closest to the max voltage of our battery pack as mentioned earlier in my post Quote Link to comment Share on other sites More sharing options...
Honeybadger Posted December 23, 2019 Share Posted December 23, 2019 I was thinking around 1650-1800kv with 6s would give me lower temperatures/less stress and more wiggle room with the gearing. The 2200kv it has originally seems really high for 6s in something as heavy as a UDR. Quote Link to comment Share on other sites More sharing options...
Ady 2215 Posted March 30, 2020 Author Share Posted March 30, 2020 Anyone know why traxxas udr prices are through the roof ? Been away from the hobby for a while was going to get back into it with a new udr. But the prices are well up on the last time I bought one. I know now they come with led light bars but they are not worth another £170 ish for them, and tbh I don't light the led set in the grille but I love the udr.
