I bought this combo https://www.castlecreations.com/en/mamba-monster-x-sm1512-2650-010-0145-04 to put in my ET48.3 and just noticed that the limit on the motor is vehicles under 9lbs. I would return it but the 2200kv combo is on backorder as is the 2200kv motor. Will I be fine just running 4s of course? Or should I look for a different motor?
