Re: Controllers?????????????????????
Did Jeremy not respond? I recall quite a few posts by him About a VERY large model aircraft motor and even about how to construct a controller to match Surely if the helicopterfiend can find a controller, then maybe it's just down to gearing? I used a high ("-ish"?) revving chinese 36v.dc ...

Re: Cambridge Crude
Hi, Tim Read the link, apparently a LONG way to go, but noticed the "etcgreen.com" link..... in one post Anti EVs, but they do make a case for: "2nd./3rd.-generation biofuels" and "growing on land where food crops will not" and "...land...used for 1st. generation b...

Re: Controllers?????????????????????
These are only guesses: 8640 rpm at 48v.dc / 150 amps ? Wonder if a Curtis 48v.dc golf-trolley controller might do it ? BUT..... CAUTION, you need a proper engineer's advice Maybe EV parts in the USA or Jozzbikes in Peacehaven, Brighton, UK or Model aircraft controller + some form of CVT to combine ...

Re: Controllers?????????????????????
Hi, from Ed the Bodgineer Not sure what would be best, but I'll start with some basic questions (then hope someone who does know will respond as well.....) Can you post any details from the motor labels, such as voltage or watts or amps? (Or am I creating confusion, perhaps these motors are not rate...
