EMax 2306 2400kv white motors initial impression

Just when you think your existing motors are more than powerful enough they get flung off the back of the hype train and a new version comes smashing through! The EMax white motors, RS2306, 2400kV are a worthy upgrade to the standard RS2205 2300kV red bottoms.

Top level summary: Claims of up t0 1.5kg thrust (running GF5050 Tri on 4s, drawing 46.4A!), 34g weight, can run on 3s-4s. Sleek white colour with red bottom. Hollow Shaft and Low Profile Aluminium prop nuts, also anodised red. Bling!

Enough of the stats though, we wanted to share our initial hands on experience of these motors and what we thought of them. Check out our quick video:

Overall we felt that the performance of these motors were a massive step up from the original 2205 red bottoms, both in torque and in top end speed. This is likely down to the larger motor size (only 1mm in diameter and height but it must be enough!) and the higher kV. However compared to the 2205-s motors which EMax have released (the later red bottoms), they have a slightly noticeable greater lower end torque but all out speed is not dissimilar.

The low end torque is definitely noticeable and suits my style of flying. It feels like you dont have to work the throttle as hard at the lower enough to get the punch you need for quick turns, compared to the old motors where you have to punch the throttle more to get the motors spinning. This is in my opinion the biggest difference I noticed!

The motors run silky smooth and appear to have very nice bearings, i’ve flown / crashed my about (outdoors only) for about 5 weeks now and they are as good as they came. They have a nice ‘notchy’ feel to them when you spin the motors by hand.

They come packaged in the usual nice little emax plastic case (very useful for storing bolts and spares!) and come complete with 2 sets of bolts which are marked 3mm or 4mm to suit the thickness of the frame you are fitting to. This is brilliant as you no longer have to worry about touching the winding’s with the bolts. Another plus is the use of a allen bolt at the bottom of the shaft for retention as opposed to the older motors which use the circlips. I think this is much better for maintenance as I was forever loosing circlips!

The only negative (only a slight thing) is that the motor shafts are rather short. For 90% of props out there this isnt an issue, but when I used the RaceKraft 5051 props, the thickness of the blade hub was such that the nyloc portion of the propnut would not engage the thread.. This meant that whenever I clipped a gate or had a prop strike I ended up with props coming off or coming loose. I managed to get some lower profile nyloc nuts which has since solved the problem. This wasnt an issue for the standard propnuts using gemfan or DAL props however.

The motors are pricey, but I would recommend them for the extra money if you are looking for a high quality and powerful build! Thumbs up from Tony at PropNuts 🙂
