K320 all the way. We've been running the G2's for a while in Mephisto's with no issues.

In the states, the price on a K320 is nearly half as much as a 300 Pro, the KT makes more power, runs on diesel - which is $1 a gallon cheaper and easy to get anywhere and support/service is fantastic... (Jet A/Kero is hard to find in the South and expensive) Also the normal service is 25 hours and is fixed at $300 I believe... and know many people that have had the service done without any issues.

The VSpeak telemetry adapter is great as well... $60 from Aeropanda... shows everything.

We just had an F3S contest in South Georgia last weekend, with 8 pilots from FL to NC... all 8 pilots flew Kingtechs... 210's, 260's or 320's... not one failed start or flame out... zero issues.
