Got Jet Fuel? Turbine Helicopters > SPS or Hotcat?

I do not know which is the better heli.After speaking to Simon at SPS, it seems that the complete heli after buying the Turbine £3500, Conversion kit £500,Heli9 Cuatro £850. is £4850, this will cost the same as the Jetcat Hotcat £4800.
The Hotcat comes as a complete package and uses a Jetcat turbine, were as the SPS is a mixture of Robbe Cuatro a conversion kit and a Wren turbine, I know the SPS is a very good option , but which is the easier option to get airborne?
The more I look into the options available the harder it is to decide which is suitable.
Please Help.

The Hotcat will be easier to get flying. You just do your normal helicopter setup, and run through the Learn-RC function on the Jetcat ECU. The Hotcat uses Robbe helicopter bits, so it should fly similarly to the Cuatro.

The SPS will require you to figure out a throttle curve and a few other things. The throttle curve is not that hard, but it won't be like a glow or petrol engine curve.

My Jetcopter is about 18 lb empty, and I would guess the SPS Cuatro with autostart will be around 16 lb. 2 l of kerosene will make its presence felt in the Hotcat, whereas the Cuatro will give you comparable flight times on around 1.5 l.
