Just got one after waiting around 7 months for delivery. Actually got the P300PRO-GL version with a generator.

A step up in RC modeling applications - amazing that once the engine is running you can disconnect the turbine battery (not that you'd do that during flight).

Had a small problem shutting down the turbine but solved it with the support of Jetcat. Thumbs up!

This engine can operate up to 30,000ft!

One last thing - very important. For the first time in history I see Jetcat allowing the user to upgrade the firmware. So you don't need to ship it back to the service center for upgrade, you hook it up on your laptop and it takes 3mins to download and upgrade the firmware.

You can find the latest upgrades here: Downloads - JetCat

Haven't tried it on an airframe yet - it may be another year or so till I install it and fly it to give feedback but I don't see a reason why it should not perform to spec.

All the best from Dubai.
