I don't think that the rafale on
www.rcarf.com is for 54 size turbines.
Look at the sizes, length 2040mm (80 1/3") and wingsspan 1460mm (57 1/2"). and a weight of 9-10 Kg (20-23Lb)
I could be possible whit the wren supersport. But whit less, than you need all the power that you have. I am thinking it is more designed for an AMT mercury, Jetcat P80 etc. etc. That class of turbine's.
But also this plug looks, like it is going the wright way.
