Team Psyclone: The Uprising (Of Build Diaries)

So, how much do these fabled Bosch's cost? I assume pretty expensive, is it worth the wait for those AmpFlows?

about £110 each

The Bosch GPA 750 is not fabled, just used a lot in heavies.
And if you want a comparable Ampflow, like suggested earlier, the E30-400 is a better bet.

I myself would opt for an Iskra AMG. More rugged than a Bosch 750, a tad more torque but a bit heavier.
Added benefit. EU manufacture. Iskra is a Chzech brand, and it means lighting or spark.
Used for hydraulic pumps on lorries and such. So sourcing them can be easier. Can...

So, is there anywhere to get these Bosch 750s, Iskra AMGs or Ampflow E30-400s in the UK? The last time I ordered from Robot MarketPlace, the order took around six months, and I can't remember, but I think one of the orders didn't even come! I just don't trust the place personally.

You can order direct from ampflow: http://www.ampflow.com/three_inch_hi...nce_motors.htm. I have been using the RMP for almost 10 years and never had a problem with deliveries. Sometimes they are out of stock of Ampflow motors but contacting their customer service always gets me a quick answer on my order status.

Check their stock status carefully: if it says 'Available' it means they don't have the item on site but its available at the manufacturer - it can take some time to arrive. If It says 'In stock' then its in the RMP warehouse and will ship quickly.

G43-500... Would that be an alright motor? I'm quite happy to go with the E30-400, but at 500w, the G43-500 seems like a viable option.

The G43-500 is a re-badged scooter motor. For about $40 less you get 1/3 the power and a much weaker output shaft & bearing. If you were planning to use chain or belt drive to the wheels, then this motor could be interesting - as long as 500W is enough to get the bot moving. I would use a simulator like the Tentacle Torque Calculator to check it. The calculator doesn't have all the exact motors you are considering, but there are some similar ones to give you an idea. Without knowing much about your design or crunching the numbers on the G43-500, I think its rather underpowered for a heavyweight.

You can use the scooter motor. If you gear down a lot, resulting in a slow machine but steady machine. You could think about using 4 off'm

The build quality ain't so bad, but for RW, we need tougher stuff than what a cheap chinese electric scooter offers.

After another quick scour of eBay, I have come across the same motors Krissy Knee on Facebook Robot Wars was talking about. http://www.ebay.co.uk/itm/24V-ELECTR...item2ece44cb47
Would these be suitable, or would they be too big etc...

[overkill]

They are very large and heavy compared to the E30-400 and adapting that 22mm output gear to hold a chain sprocket would be a PITA. I would still go for the E30-400 or the GPA motors.
