The 1515 are also fine in a buggy. I have run a 1515 in my buggy many times. It doesnt really drive much different that the 1512. It will get slightly lower motor temps than the 1512 but it also gets slighly less run time. The 1512 is plenty of motor for a buggy and motor temps are still fine as well. If you plan to race it go with the 1512 to save the weight IMO but a similar kv 1515 would be fine as well if you want to go that route. A 1515 would give you the option of carrying a little taller gearing if you wanted to gear it up for crazy top speeds, but on the track you really dont need more than 40 mph and the 1512 can easily provide that. (and more if you want it)

I am partial to the RC-Monster stuff. The original and still the best IMO. The Tekno stuff does look nice, but the clutch is a negative IMO. I tested a setup with the Tekno Clutch and didnt care for it at all. The direct drive is the better way to go for electric. (At least for my driving style it is.) The clutch also forces you to run the mechanical brakes and in a buggy I didnt see any benefit. (just more weight and complication) I do run mechanical brakes in my brushless truggy and do like having the brake bias ability, but truggies require a diferent driving style to be fast and the fast guys tend to have a little more "loose" style than the fast guys in buggy where it reqires a little more precision to get around the track fast.
