It's a shame you don't have the space/weight for a scooter motor, they seem to work quite well

[adz600]

really lacking power they are low rpm motors but really struggle to get the axe to move it would need a large ratio change from 7:1 ish know to 21:1 ish I used to rum with mfa 4:1 epicyclic geartrain

[mrsam]

What about the mfa 800/850 motors? They seem pretty powerful

[adz600]

would also require a 2 stage gear reduction, its the axe weight that causes the problem just over3.2kg

[mrsam]

Wow really? It doesn't look that heavy, that's over double what mine weighs and I was worried about the weight of that. Seems a second stage reduction is the only viable option although you might need more powerful motors

Did you measure the amp draw?

[adz600]

No but couldn't have been alot as it feed though a 30amp fuse

[maddox10]

6S 30A= WAY below the capacity of a real speed 900 or even the clones.

Kashei fries the PCB's of the motorcontroler, and that's normaly able to cope with 100A+, with 1 speed 900 (what fries too on a regular base)

[adz600]

Its running of an 30amp electronize unit, I wonder if they have current limiting ie, bridge bypass,or resistor bypass, might hook them upto the tz85 to try them again on 6s

[maddox10]

The electronizes don't have any way of current limiting. If you overload them to much, the relais will pop, and if those fuze, the fets will go.

Testing it with a TZ85 is an option. But I suggest a 100A fast fuse then.
