Much of the delay in releasing the 5mm shaft upgrade kit was getting a good supply of the end bells. We're going to reserve the parts we get in stock for the kits until we are confident of receiving consistent supplies.

We will release the upgraded motors in a couple of months---adding some additional motor winds Bob has been testing.

What wind motors do you suggest? We can offer whatever customers want---we wind all the motors here.

id like to see something in the 2200-2400kv range

my hv 4.5 is making the tires look like 6.5" plates on 4s in a xt8, but its geared 15/48

As a customer before me stated. Something around 2400Kv. My 6.5 at 3100Kv was almost right for my 1/8 buggy. I had to gear down a bit (10 or 11/46) to keep it cool enough to make a 20 minute main without a controller thermal. I don't know the Kv rating of the 4.5, but that motor is not suitable for racing. A few of the guys around here tried them over the summer. Fast as all heck, but it thermals the controller quickly. I think the longest anyone lasted with the 4.5 was about 11-12 minutes on a cool day. So, the 4.5 is suitable for bashers. The 6.5 is very nearly suitable for racing. I think perhaps a 7.5 (or whatever you want to call it) at 2400Kv would be excellent for buggy's on 4s.

great info, thanks


and the 4.5 is 4800kv from what i could find, i looked at my info in the calc. and it said 72k rpm and like 84 mph, no wonder it cogged a little bit with 15/48 gearing on a mm
