You continue to impress, very nice build! When you pull back on the lever that depresses the fuel canister and injects the fuel, does the fan also turn on and vent the chamber at the same time?

Nicely done as always, French spudders keep putting the rest of the world to shame :)

Mr Crowley :When you pull back on the lever that depresses the fuel canister and injects the fuel, does the fan also turn on and vent the chamber at the same time?
►it's like that: i pull back the lever, that depress the fuel (régulated flow with a faucet), open the chamber valve, turn on the 9v fan to refuel the chamber.
It's the same system on my gatling and my spas12.
but in this version, the system is most compact.

The gaz flow is réguled with the faucet, in accordance with the air flow, to make a perfect mix.
