Oh, yeah! They are a bit more expensive, but cheap and fast on shipping. I just got the motor, esc, and batt they kind of 'packaged' together. I used a prop that probably pulls a bit more power than they recommended, but it's working great in that no component seems to get hot or even warm. Conservative flying, no aerobatics, maybe 2 takeoffs max, on pontoons, I can run for about 10-12 minutes without taking too much out of the battery. I did get a 'watt meter'/battery checker. Here's what I know about that stuff: 1) LiPo batteries cannot be drawn down too far in most cases. Most people don't recommend drawing down to less than 75% or so. This seems to fly in the face of the rest of our battery experience, which is use it up to no power, then recharge. However, receivers and esc need a minimum voltage to work at all. Thus, most esc have a 'low voltage cut off', meaning that somewhere close to the minimum voltage needed for the receiver, the motor gets weaker and finally stops so that you have a little reserve battery power to make a 'dead stick' landing. Not good if you're flying over dirt with pontoons! Somewhat doable if you are on wheels, but not recommended. So better to use a meter that shows how much batt power you've used, convert that in your mind to what kind of flying you're doing and for how long so that you can land with full power and control. Then change batteries or go home, everything in one piece. 2) In most cases, if the battery gets down to a certain point, maybe 50%, I'm not sure, maybe lower, the charger may not 'recognize' the battery and won't charge it! Even at $10, that's no fun! Another reason to not always fly to that low voltage cut off level. 3) Watts relates to the 'intensity' of power being pulled from the battery at any given moment based on the throttle setting and prop you're using. If you exceed the 'rating' of the esc, you can blow it, then you've got no control, could ruin most components, etc. Thus, you need to be aware of not 'over proping' the motor, esc, combo. You can use a multi purpose watt meter/battery checker, like I got from HeadsUp, to not only check the levels of a used battery (or charged one), but also to measure the amount of watts being pulled by your motor/prop combo. HeadsUp has already figured that for you on the page you click to from that motor mount. Well, I hate to expose my technical ignorance about these things for all to see , but I think it might help you a bit anyway. Good flying! jo
