Scrap my last comment about the HTI motors seem to be performing ok. Burnt them both out today when demo-ing it for some family members. Think I may look at speed 900s going through a gearbox before the belt stage as an improvement. Other than that, the drum span well with them.

What is the situation with speed 900s I thought they were now discontinued?

thats what i heard and does any 1 know a motor with similar specs to the speed 900 which is around the same price

It seems you still can buy m.

We just bought a nice supply of them, just to be sure.

We have 12 spares then.
In the end ,its just another Johnson motor.

i only have 2 spares for each robot maby i should order some more do you think a mini ev motor would be as good as the speed 900

Graupner have now stopped making them, and most UK model shops dont stock them anymore.

The funny part being that Graupner wasnt making them to start with.
They just relabel Johnson motors, like the Johnson PMDC HC987LG-001 (a.k.a. Speed 900)

Im not complaining, i too have 12 spares

I dont know how much power you will generate with that axe, but it could very well be your axe will swing your robot instead of the robot the axe.

i was thinking about that the other day i may need to do hardox armour as i have the weight might keep it down abit more but would meen it would be 13.6 instead of 12 so no room to upgrade if i wished
