A Flite Streak makes a pretty good engine test bed.  It will fly (not well) with a very anemic 19 and if the engine turns out to be a screamer it will speed up a lot but still be stable and controllable.  A fun airplane.

  I would try running it like an LA or FP.25 in any airplane that you have rad on here that people us those engines on. Get a Ringmaster for it. Everyone needs a Ringmaster so you can join in on the Brotherhood of the Ring Fly -A-Thon each year! Try anything from a a 9-4, 9-5 to 2 10-4. I generally use a 10-4 on my .25's spun up to the 10,000 RPM range. Same with the fuel, unless it's an old iron engine. I have two Royal .25 NIB put away I need to get out and play with some day. They have carbs on them but I'm hoping OS stuff fits them.
