Just from the description of some problems, you know it's a brushed motor. But the $52 says it all. You can't get a set of brushless motors for less than $40
& that's 1104-6 size. Probably would be a good flier but it should be made very clear that as soon as the props touch somthing other than air, Cut that dam throttle,as the pinion gears are made of plasticine err plastic.
