Yes, this is great news! I've thought about getting into hybrids a few time in the past and kept hoping that the Alphas would get certified soon due the lack of expensive GSE. I noticed the July 4th date, will you have any of these at LDRS?

Edward...

Spill the beans - Candlepower? I assume wax?

What's the retail price of the system?
What's the reload cost per flight?
What's the minimum GSE requirement?

Candlepower....that's the fuel. I guess you'll have to try it to see

The motor hardware will run $250,
reloads will be 3 for $50,
and GSE varies on what you want to do.

I can sell you the mating valve for the tank and you can tinker together your own GSE or I can sell you the GSE I use (fill valve, dump valve, 3' hose to connect to tank, 326 or 600 supply tank fitting and a pressure gauge) for about $130 - all those parts add up
