Default Jet turbine reliability

Sorry John, havent been on the forum for some time. The 40l l/h is what the JDU displayed, and it seems to be reasonably accurate. Also, I dont run it at full throttle, but rather at about 90k RPM.

What is the weight of the JS1 jet and 45 minutes of fuel over the weight of the un-engined version.

+49.7kg - of which 35.2 kg is fuel. Add to that 7 kg additional nose ballast for a 90 kg cockpit load and the wingloading still low at 38.7kg/m2 in 21m and 41.6 in 18m.
