That wren needs some adjustments to the kero start parameters, its a very long hung start , and shiukd be cleaner and quicker starting than that . They are a great little powerful turbine , it will be fantastic in the wessex
@@bladesofthunder9778 My 1.9m, 1880 disc, Vario BO105 is 11.5kg dry. It is marginal on power and needs plenty of pitch to hover. Try to keep that weight down. Wren's claim in the manual that it will lift a 50lb (23kg) scale model is frankly ludicrous.

@@simontait8649 Should have plenty of power. On speaking to a friend who has a Wessex and wren 44 combination his is over powered but we shall see
@@bladesofthunder9778 Out of interest, what rpm on the output shaft have you set the gearing for?
@@simontait8649 I haven't set the throttle curves yet but will be looking at around 1100-1200 rpm
Would of been nice to see the rest of it not just a top veiw
