Scorpion 900kv feedback?
Anybody have anything to say about that new Scorpion motor they made for the full size Protos? I'm about tired of the nuclear temps in the stock MSH one and looking for options. Seems nobody really makes anything in this kv range so choices are slim. /sob

Im running one on my Protos 500. I love it. Out of the box, it has lower temps after flights, my ESC (ice 75) loves it as well.
What I have done just as of recent is to swap the two bearings for Boca ceramics (ABEC7) orange seal , this upgrade will make huge differences to your motor as well when it comes to temps.
Note:
due to the larger can , the 3226 series motor that replaces the 3026 now use a larger lower bearing.
3026 series lower bearing: 10mmOD x 5mmID x 4mmH
3225 series lower bearing: 11mmOD x 5mmID x 5mmH

One thing you will need to do is to trim off some material on the frame to accommodate the motor because of its larger size.
3226 @ 40,90mm OD
3026 @ 37.50mm OD
note the frame at the top of the motor:

That my friend is exactly the feedback I was looking for. I'm skilled in Dremel use and I have the carbon frame (stretched & FBL) so I'm sure I'll get it in there no problem. The measurements are exactly what was needed too. I vowed a few years ago to never buy Scorpion motors again but alas I'm without options on this one unless I get the Hyperion 880kv remake. I pretty much figured I would be going to Boca anyway as I simply don't trust Scorpion bearings at all.

Thanks for the report brother. New Jive 60LV in route now and the Progdisk showed up today so I can fool with the other two Jive HV's we have already. (never did get around to changing the BEC voltage on my HV120+)

Keep em skids down my friend. /thumbsup
