NB: This is a un-cut or edited video of the first two test runs of a Wren 44 Heli Turbine that had the misfortune of being in a crash (Trex 700) and had been sent into us for repair.
In the video Alan Wheeler and Denis Cleobury of Wren Turbines test run the engine after repair. We even left the air bubbles in (first run) to show that the engine would still start.
During the repair work we also upgraded the combustion chamber to include our NEW i-Kero Start System.
As you can see the engine starts very well with no drama or flames exiting the exhaust. EGT at full power was just 386 deg C
See our Facebook gallery for some before and after photos of the engine: https://www.facebook.com/media/set/?set=a.250756588459184.1073741866.154656198069224
