No test vids atm. As axe it's not very powerfull, but as selfrighter it's showy.
The drives.
We use the MSR 12-54/Ilyama Scorpion XXL combo drives for 5 years now, and had only 2 failures. 1 because Little Hitter shattered a magnet in 1 motor, seizing it. The electronics never cared about it, the current limiter doing a great job.
And another during demos. Just stopped. Ilyama checked the electronics, took small pliers, removed a tiny bit of swarf from the pcb/controler legs, and that one still is running , called Hannibalito III.
Another Dutch user of that combination had rather spectacular damage from Hornet , one motor lost the gear ,and the axle was bend 90° in front of the forward bearing. But after replacing the motor, it was good to go again.
I didn't get any further imput from the UK were several people are using those drives.
There is only 1 disadvantage. These are heavy. Easely 1.4 kg for the motors, wheels and gearing (and we get our main gears custom made in ali Mod 1 Z54 or Z72)
On 12V they have fair power and incredible speed. On 18V it's getting ridiculos. If we want to use the voltage limit on the scorpions, we'll have to use a greater reduction, a 2 stage 15/1 or so. The torque on the 900's is good enough , 1.1Nm stall @12V and 6600 rpm nominal. 12V 13A is nominal power.
