Evo_ermine Posted October 23, 2012 Share Posted October 23, 2012 I need a motor/ESC system for a Ansmann SC4 truck. I think I'm right in saying it's based on the buggy but with bigger wheels. So what recommendations do you have for a motor. I'm more interested in picking a sensible motor for racing on a 2S rather than bashing. Looking at some RTR 4x4 trucks, some come with a lowish KV rating and others with higher ones. I read a thread a while ago where Si Coe was helping someone with a Ansmann SC truck and it turned out the motor wasn't good enough but I can't seem to find it. Any suggestions? Ta.

.AJ. Posted October 23, 2012 Share Posted October 23, 2012 The most popular Kv in 4wd SCT's at the mo is 4000kv - 4600kv on 2s You need decent lipos tho, 50c+ as the high kv motors tend to be very amp hungry Quote Link to comment Share on other sites More sharing options...
UltimateRC Posted October 23, 2012 Share Posted October 23, 2012 I'd want quite a lot of torque with a SC so I would go with 3000 - 3300 . Quote Link to comment Share on other sites More sharing options...
heavyleftthumb Posted October 23, 2012 Share Posted October 23, 2012 around 3500 is spot on,on 2c still gives you silly throttle lol Quote Link to comment Share on other sites More sharing options...
Gaz! Posted October 23, 2012 Share Posted October 23, 2012 i have a tenshock 3500kv motor in my exo buggy (in essence a 4wd sc truck) and the torque is fantastic on 2s, coupled up to the sc8wp esc. Quote Link to comment Share on other sites More sharing options...

DreXeL Posted October 23, 2012 Share Posted October 23, 2012 We are running a 4000kv SC401 in my Son's Hyper 10SC on 3s and the thing is mental fast. Quote Link to comment Share on other sites More sharing options...
.AJ. Posted October 23, 2012 Share Posted October 23, 2012 (edited) We had a Hyper SC with the 4600kv SC401 at our track and it used to out run a Durango with a Pro4 4000kv for fun Both geared for around for the top speed Edited October 23, 2012 by .AJ. 1 Quote Link to comment Share on other sites More sharing options...
Si Coe Posted October 23, 2012 Share Posted October 23, 2012 The Ansmann's not a real shortcourse though - its a buggy in drag. The big 550 motors won't fit and the drivetrain isn't built for that sort of torque anyways. You want a fairly mild 4wd buggy motor - something in the 7.5-8.5t region so around 4000-5000kV but not a 4 pole or SC specific. Quote Link to comment Share on other sites More sharing options...
Evo_ermine Posted October 25, 2012 Author Share Posted October 25, 2012 Thanks for your suggestions. Been looking at the Etronix range as they're cheapish. I actually have their 3930kv system in my Buggy and it's very fast. Thinking of removing it and using that to save myself Quote Link to comment Share on other sites More sharing options...

tachikoma1373 Posted October 25, 2012 Share Posted October 25, 2012 EZ-RUN Brushless Motor 12T 3300Kv (UK Warehouse) Quote Link to comment Share on other sites More sharing options...
Si Coe Posted October 25, 2012 Share Posted October 25, 2012 I'd avoid the blue finned can Ezrun and Etronix motor - the SC4 may not be full sized but those motors aren't even 540 let alone 550! Something with a proper full sized 540 can is needed, but nothing more. Quote Link to comment Share on other sites More sharing options...
Nathanio Posted October 25, 2012 Share Posted October 25, 2012 EZRun 8.5T 4000kv would be perfect or the Reedy (Associated) 550SL-3500Kv/4000Kv. The Reedy 550SL isn't a true 550 class motor and is somewhere between 540 and 550. Nicer as a little bit more torque. Can get them on the Bay for quite cheap.

Understand where you are coming and think on balance you are probably right for a 4x4 but I would say if speed is not your thing and you keep the gearing at stock or lower you probably wouldn't have any problems - I know I haven't in either my Slash (SBS 2.0 9.0T/4370KV) or my Rustler Baja Bug (SBS 1.0 (13.0T/3000KV (despite what my sig says). The SBS 1.0 was second hand as well so in reality I have no way of knowing how it was thrashed prior to me having it and its taken more stick than the new one. Not saying your advice is wrong at all just that if you set your expectations appropriately and accept the potential risks then they are still valid options at a reasonable price. That said I've have just switched to an HPI system (4000KV 4 pole) in the slash as I'm looking to try some 2.8's on there and figured that would definately be putting strain on the motor given the varied terrain I bash on.

DazzaClio Posted October 25, 2012 Share Posted October 25, 2012 I run this combo in my Slash 4x4 on 2s geared correctly and it goes very well . If got a couple of the WP SC8 Esc's and havent had one of these motors before and i must say im very impressed with the motor. http://www.rcecho.com/HOBBYWING-EZRUN-3656-4700KV-RC-Brushless-Motor-WP-SC8-120A-ESC-Combo-ME180.html Thanks.
