If you want to do a 2s-3s setup, go with a larger can motor - the factory brushless is a 3660, 2700kv - years ago the 3660 was called the 1/8th scale motor 😉 $23 gets you this https://www.amazon.com/GoolRC-3800KV-Waterproof-Brushless-Crawler/dp/B07BF765LP/ It's what I have in the quanum vandal right now - Ive never run 3s on it, but plenty of power on 2s - I mean anything that you put it in, I'd think you will be able to gear higher than a 3650 of the same kv because of the additional torque from the longer can. There is also a 3660 4300kv cheap on Amazon, but it doesn't have the 5mm shaft - I tolerate the smaller shaft on 3650, but I demand beefyness from all my longcan (ie MY FAVE!) motors🤣
