The LA 15 will definitely fly the Flite Streak - especially the Top Flite ARF version which has been lightened up quite a bit. Try it on 52' lines. The perfect choice for the ARF Flite Streak has been the now discontinued OS FP 20 with a stock muffler (the 2030 version with the internal baffle cone), an APC 9-4 prop and Sig Champion 20% castor content and 10% nitro fuel. Use a green Bruline air filter over the venturi and set the needle for a wet 2 cycle.

Much has been written about this setup on other forums (some pro, some con) but everyone who has tried it (including me) swears by them. So much so we have driven up the prices of used examples on eBay to the stratosphere. But, you can buy a junker 20 FP and still get replacement parts through the distributor to bring them back to new specs.

The 2nd choice would be the LA 25 engine. Note that Brodak will be releasing a 25 engine which will be a smaller version of their Brodak 40.

I've also flown a Fox 35 on my kit built Flite Streaks and they are satisfactory - but the FP 20 is perfect.

I am running an Enya 35 on the original Flite Streak and have no problems with vibration. It does go fast but it is a good trainer and agood slow combat plane. 60 foot lines. Also have a super streak, 47 in span scratch built from Jan Rummery plans. Silk and doe finish. 60 foot lines with a fox 35. Areal solid plane and very smooth. Hope the picture shows up on this post.

I saw you with this down at Sig. Any news on commercially producing it?
