[ausev] good motor generator

[m. edmund howse]

The new motors I've seen that were around 15 hp, continuous, were 
between 2500 and 3500 bucks but they were premiere motors of the highest 
quality.
This motor is probably 15 peak but it seems I can't find much info on 
it. And I have looked for motors at the trading post previously without 
much luck and this particular motor I wouldn't
consider to be a good buy for various reasons but you're right about 
looking for a really good motor for a final selection but then since 
I've been in R&D all of my life I like to work up to
the equipment I want to use and not just take anyones word for my final 
choice even though they may have something that works. Good for them 
food for thought for me.
