Dirk:

I have flown my personal Flash with the Falcon - 23lb and the Super Eagle - 30lb. Flash has been flown with 18lb thrust turbines.

Rabbit is producing 20lb thrust. Will be very good as a power plant. Total all up weight with both tanks and the Rabbit should come in at 26lb with fuel.

For unlimited vertical, I would go with the Super Eagle and then reduce max RPM to 124,000. This is what I feel to be the perfect set up. With both tanks, you will experience 10 minute flights with no worries.

Thanks for the question.
