I have just been running on 36V again - and pop went the controller - well, more like a BANG!
This occurred because the chain tensioner is not pulling tight enough to keep the chain properly seated on the 10 tooth sprocket - leading to current spikes probably in excess 200A.
TBH today the start performance has been getting worse and worse - its all fine once you have been to top speed once - then it seems to 'remember' what to expect - up to that point though its pants.
I have a spare controller so it will be back on the road today.
Next steps are a delrin wheel (or maybe just a a bearing...) above the sprocket to hold the chain on when the rpm's rise and a different esc.
Been looking around at the types used on giant scale and Maxi joker heli's and it seems the Power Jazz is the one to have. I need to check but I think Matt has mentioned this controller as being a good one?
Anyway - specs look awesome and its waterproof so cooling will be a non issue
Gonna place an order if I can find positive reviews from people pulling 100A+ continuously.
