Yeah kinda has a Rocket-esque feel to it doesn't it? I'm a fan of this combo!

A 520 on the Panther...do you foresee an expansion of the Vne in the future for the airplane? (This assumes LSA compliance is not an objective)

UL520 - lighter than an O-320 and up to 200 HP, and about the same money as an O-320, what a combination.

Hi guys
Dan you will need the short 55mm flange to work with the cowl. The UL 390 and 520 6 cylinder engines will use the 90 mm flange. If you are considering a UL (350 ,390,or 520) you can contact SPA and order directly so your engine is properly configured with the correct hub, and exhaust system. You Will also get a substantial "package discount " By ordering your UL engine, mount , and cowl through SPA.

The UL cowl looks just like the Universal cowl , but longer. the UL series is very "bulky " in the cylinder area ,and the top induction tubes. this requires a cowl very similar in size to the 0-320. Also the exhaust system is too wide for our narrow cowl ( both straight pipe , and muffler systems) so we are working on a Panther Spec exhaust system to be supplied with the engine.

you will see pics on this and some other cool projects on our site soon

That's what we need, a PT6 powered Panther! Haha, probably not. Maybe the 390 would be suitable 'ballast' to shorten up the nose moment however, with the Lycoming cowl? That'd be a rocket...hmmm..things to ponder as we blow through the LSA top speed.

Looking forward to seeing how your long nose version looks in the meantime!

The CG issue was that the universal mount was too short, thus the CG being too far aft. I am not sure how much farther forward this is, but I suspect around 5".

I don't have any factual information on the cowling yet, but I am sure Dan will let me know when it is ready. I want to be able to pick it up at Corvair College in Barnwell in March. I won't need it before then. I am expecting to move the Panther to the airport for finishing up, around the end of March.

Perhaps a single 4" diameter pipe out the side of the long cowl so it looks like a turbine under there...just kidding.

I'm guessing this is a CG issue that could be solved by a shorter (Corvair length) mount and shifting some of the weight forward to keep the same CG envelope. Although, the long nose will probably look cool!
