I’ve been running this 3674 3600kv motor in a Typhon 3s for about a year now. The original Spektrum motor worked fine, but I wanted to run a 17t pinion in summer temps without worry. I transferred the stock heatsink and fan to this, and it’s run every bit as cool, if not cooler, as the stock motor did on a 15t pinion. The power delivery is honestly smoother since it has more torque. The 5mm D shaft is almost a direct fit for Arrma pinions, but the flat side has to be extended 3/8” or so in order to accept the full length of the pinion including the grub screw. A file would work, but I used a Dremel with a metal cutter that made short work of it (less than 60 seconds). Alternatively, you could just use a standard round shafted pinion. Great motor for the price.

No good,can not handle high speed,comes apart in the can

Very strong motor to say I only used it on 3s.

I bought this to replace the stock motor in my senton 3s and what a difference. It stays cool not even warm and boy does it rip. I blew apart 3 out of 4 tires in the first run. Super great performance for a good price. Will definitely buy again for other rcs

So the 3674 came with poorly threaded screw holes that needed to de burred. The motor shaft flat section is long enough for most pinions. The grub screw ends up on the round section. The 3674 is a waste of money and not worth the hassle of making it fit. I should have returned it. I have multiple 3650 3300kv pyre motors that are an amazing value. Very surprised at the quality issues, 3650s have been spot on.
