Davejm1980 Posted January 6, 2023 Share Posted January 6, 2023 (edited) Hi. Dug my schumacher cougar sv2 out the other day. Bought new lipo and it's running. I bought the motor esc combo back in 2015 one of those orange leopard sets. It's 9.5t. Running 2s lipo Questions. 1. fairly often while using it, it will not drive and stutters (see attached video) (took spur gear cover off for video) 2. Is 9.5t the right motor for a 2wd buggy? I'm not not a great driver but I really struggle to get the power down it'll spin the wheels at 20mph+ or would a gear change help. When people refer to a motor speed and torque, does torque mean acceleration over top speed? 3. Is a different topic. I want to build a couple of tamiya kits. Blitzer beetle Racing fighter or sand viper And probably a Lunchbox (because everyone should have a lunchbox) I know quality/tunablility wise they'll pale in comparison to my cougar but it's kinda wasted on me with my limited driving skills. Was going to go for a tamiya sport tuned brushed but with 2s lipo with these kits. Or is there a slower more suitable brushless set I could use? Especially in the lunchbox and blitzer being trucks. Any advise really appreciated VID_20230106_150455.mp4 Edited January 6, 2023 by Davejm1980 Quote Link to comment Share on other sites More sharing options...

ReggieC Posted January 7, 2023 Share Posted January 7, 2023 9.5t is fine for a 2wd buggy. If you think it's too fast, see if you've got the capability to turn down the punch on your esc or the throttle dual rate on your transmitter to make it a bit more controllable. You're experiencing some pretty nasty cogging there. The fact you're talking in motor turns rather than Kv suggests you've got a sensored system, so I'd check to see if the sensor wire is still attached and if it's all in one piece first!

Thanks for the reply. It's actually sensor less and 9t. I was just reading what it says on the side re using turns I've forgotten a lot of what I learnt the first time around. Kv is 4370 What can I do to stop the cogging? Thanks Edited January 7, 2023 by Davejm1980 Quote Link to comment Share on other sites More sharing options...
