I am upgrading a wltoys 144001 to brushless. I should have waited since they are upgrading the 124017/124016 with a 19t pinion and a 4300Kv. However, I am using a 120A hobbywing ESC and I don't have an issue with cogging. It makes for a very spirited car. I recommend a gyro enabled transmitter/receiver to keep things under control under acceleration. I am using a Flysky FS-GT5 which is awesome.
Motor looks good should work good with the RC.
I haven't installed this yet, originally purchased for my 124019 but I misdiagnosed the condition with that car and my 3650 brushless is still good on it. This feels like a really good quality motor, nice and tight with no play at all hardly. thinking I'll throw this on my A959-B as a little upgrade for that car. I would highly recommend this motor for whatever chassis you're working on if you're looking for this 2845 size.
Product not recommended for wltoys 144001...
