I have asked PST to send us the scale kits ASAP and will have an answer for you by the end of the week.

As far as I know, this size Panther ( at 23 - 27 lbs dry ) has been flown on the Artes Falcon, JetCat P70, P80, P120, RAM 500, 750, PST 600, 600R, 1300R, Wren 54.

Personally, I have had the opportunity to fly the Panther at both sea level ( 15 C ) and at 2200ft msl ( 20 C ). With a 12 - 14 lb turbine the Panther requires 60 - 70% power to maintain a comfortable 130mph cruise which allows for some climbing turns etc. Application to full power in level flight prior to loop entry is required for a proper loop ( as compared to an egg shaped, lower velocity type ). The Panther flys in a very "SCALE " like fashion with these power plants at both sea level and at elevation.

If you are looking for a little more vertical or prefer to maintain a 50% power setting in cruise then a 17 - 20 lb turbine would be ideal. Interestingly, the plane does not appear to gain significantly more airspeed compared to 14 lbs of thrust - where it is noticeable is in the vertical pull. Keep in mind that the kit comes with a 2 litre fuel tank. It would be wise to add another 40oz ahead of the main when using a larger engine. Although my demo model weighs 23.5lbs dry, the plane can easily gain an extra 2 - 2.5 lbs with no flight penalty.

We are starting a Panther kit that has a customer supplied P70 and I get to do the test flight! I think that will be a great combination!
