I wonder how some traders sleep at night

They probably get royalties from that Horlicks ad.

I hadn't thought of that, Doc

Sorry Dave, I hope I didn't imply that you were pushing your stuff. It sells itself to me as in my opinion all the Action gear I've used is top drawer and I'd go for it every time if I could. I was just pointing out my reason for taking a punt on something else, it didn't work out but as I said I learned something and at a reasonable cost IMO.

If this topic had been here before I bought the Chinese esc frankly I wouldn't have bothered, ain't it always the way? 

Out of interest, what esc would you recommend for this?

Graupner Speed 700 Turbo 9.6V (3308)
5-pole armature
Nominal voltage 9.6 V
Operating voltage range 4.8-14,4V
No-load rpm 15000
Current drain at max. efficiency 12.5A
Stall current 65A
Part No: G3308

I want to use 9.6V (8 cell) and 12V (10 cell) power packs, with a 38mm 3 bladed prop that has a fairly coarse pitch. It's pushing a 37" MTB. Any suggestions? (Pretty please) 

Cheers, Andy

And I'm sorry for the rant at your expense, dude! I'll send you a PM ref the enquiry.

I burnt out one of these, got a second one, and it works.  So yes, caveat emptor.

I think the problem is not so much the equipment itself, which is manufactured with a reasonable quality of workmanship, but the nebulous, unknown specifications for it.  Obviously, 25 amps is a joke, and 110v would reduce it to a smoking crater.  It's not waterproof either.  So while the ESC works, I still feel nervous every time i flip the 'on' switch. 

Having said all that, R2Hobbies has excellent shipping and response time, so thumbs up to them for that.

Andygh,
For your MTB the MMB 900 on 12 volts and a larger prop takes some beating.
