RE: Which big turbine...AMT...JC...or ?
John,
Sorry mate can't help you there - I only use airstart AMT's. All my startup equipment stays on the ground - don't believe in adding more wing loading than I need and hate to have to buy startup equipment for every jet I own. What's more, why carry in the plane what you need on the ground, in the air?
As for start-up gas, I just use the Butane 70% and Propane 30% cannisters that you can buy at any camping equipment retailer - personally prefer the Coleman's brand.
Cheers
Jan
