Keith,
We are no longer allowed to fly at Pulaski. According the FBO operator there, the local "FAA" has forbid any R/C activity there. Have been told that we may be able to fly at Lawrenceburg or even Columbia, but I have not confirmed that. Scott and his fellow jet guys have been flying in Nashville or Bowling Green, and BG has a great field, but it is just too far for me since I am 100 miles south of Nashville. We have a good grass strip here, but not too great for most jet aircraft.

Hey Keith,
We have been flying many of our turbine models at Peeler Park in Madison, Tn. The runway is only 40'×400', but I have flown my large SM F-4, FeiBao MB339, and currently flying the Aurora from that same site. Others have flown the small and large Futuras, Comp Arf Lightning, SM 1/6 scale F-16, SM large Hawk, Eurosport, and an assortment of other non scale turbine-powered models.
The Skymac field in Bowling Green, Kentucky is the other location that is used, but I only go there when I need to do a maiden flight. The runway there is 50'×800'.
Doc, I am waiting to hear if Beila, Fiala, or SEP will custom make either a three, or five blade prop in the diameter/pitch that I need for the PC-21.

thanks, If you ever feel like getting rid of that mb-339 let me know I might be interested I was looking at this kit for a nice everyday flyer for scale. I am a big fan of the desert and green camo schemes
Well I will try and get down to peeler Park in the next two weeks before I go on vacation.

The verdict is in...
I got a flight in with the 25/17/3 on Sun., and the performance was much improved! The vertical performance was MUCH better while the speed "seemed" to only be barely more (visually, not actual recordings). I do have a custom "scale" prop that came with the plane that I may try, but I have no idea of the size. It is bigger in diameter than the SEP, but I have no idea of the pitch. Other than that, I think I'll be sticking with the 25/17/3 for the Raven, but may give one of the Bielas listed above a try one day.

Thanks for the info David. I think initially, I'm going to try a Solo Prop. I have a three blade Solo Prop for a Corsair and the pitch can be adjusted from 0 to 24 degrees. I would be interested in hearing how the Biela works out.

My current plan is to use the 24x17 SEP three-blade prop for the maiden flight. If the performance is decent with this prop, I will use it for the remainder of this flying season. I may just save the Skymaster prop for the K100 TP when it is released

That turbine looks great. How it comoRes to the SPT-5 in terms of power ?
I have 2 x SPT-5 in CARF airplanes. One moves with authority a Marchetti and the other one is only OK for the Tucano. The Tucano is an older model and a heavier one so it would benefit of more power. I've been thinking on a SPT-10 but this new Kingtech looks like a good alternative.
any my reports on performance in the future would be appreciated.

The suggested prop for the Kingtech 60TP is a 24x20, or a 24x22 three-blade prop. If I remember correctly, the suggested prop for the SPT 5 is 24x12, or 24x14 three-blade. Started my K-60 TP for the first time this past weekend using a 24x17 three-blade SEP prop. Only ran the engine for a short period, but never above
1/2 throttle. I was impressed by the power of this little jewel. (Manual states power is 7.3 kw at 7000 rpm)
