XPower F3426/7 Storm 1250 RPM/V 142g Cased Outrunner

Purchased the 1250 rpm outrunner & carbon prop for my Dream Hotliner 2.0. Postage to Country Australia was 2 weeks exactly. I have installed and tested but not flown as yet. Seems to have plenty of pull and carnt wait to get this airborne Neil has been absolutely excellent to deal with and I will be purchasing more products in the future.

Motor arrived on time and as advertised. Good thrust for F5J XPlorer2.

Nice powerful motor. I have used both Xpower Windy and Light motors in the past; of course this one is more powerful and larger, but seems every bit as satisfactory. With 11x8 prop and 4s will pull around 800+W, as stated - but you will need a battery that can supply the required current without too much voltage sag to get that as continuous output (I used 850mAh Tattu Rline 4s, and could get the stated power only at peak - more like 700W steady state). An 11x7 prop was too small and 12x8 was too large (though maybe it would be OK with a larger capacity battery; over 1kW peak).

A few notes:
(1) the front end geometry will almost but not quite work with a CN 32mm mount: since the back of the mount and the front of the motor are both conical features, they mate before the front of the motor meets the back of the mount. Fixed this by fabricating a 2mm spacer from G10/fibreglass sheet;
(2) the motor and mount will just fit inside the hatch and nose of a PlusX - requires cutting the nose back 20mm to go from 30mm to 32mm spinner/firewall, and even so the fit is tight. So it will possibly work with other noses designed for 30mm spinners, too, but the fit didn't leave a lot of room to spare;
(3) the motor power leads (unlike smaller Xpower motors I have used) are enamelled stranded copper. If you decide - as I did - to cut them shorter you will have some trouble re-tinning them. Fixed this by fanning the wires and abrading off the enamel with sandpaper (this is apparently s standard treatment for re-tinning enamelled copper wires), then re-twining and tinning with solder.

Enjoy.

Cracking motor performance is awesome. Long term who nows? It's nicely made but we will have to wait and see...
