I bet it won't take them long to find the right purpose built airplane for this event.
I see a foxbat about to emerge with a LA 25 in it.

Some good sport race designs for the LA25's are the Artesian and Super Fly. The Mongoose is also a good design, but can be made better by reducing the wing thickness to the allowed 1". The Artesian was designed and kitted by the late Dick Peterson from the Seattle area. I currently campaign two Artesisan's and they are great racing airplanes.

There is one other design that makes a good sport race airplane and that is the Vulture, which I think is actually a profile carrier design.

I'm in agreement with you on the ARF Flightstreak. One of our club members bought one to use in our sport race event, and quickly found out how flimsey they really are. The fuselage is Built up, not solid. He found the fuselage area around the motor mounts crushed very easily. Also, the thick blunt forward high point airfoil of the "streak" is good for stunt, but the purpose built 1" thick airfoils with thinner leading edge and highpoint further back are better for racing.

We talked the Reading Flyers to host the first ever LAFOXberg a couple years ago.  It worked out fine.  With the standard needlevalve and venturi for the LA 25CL it ran middle of the pack with the various Foxes.  Nice and smooth running, easy to handle, and easy to pit.  A perfectly fitted Fox may be faster, but nobody has really worked much on the LA's.

The 2006 race at reading was won by an OS 25 LA with a metal back plate and an APC 8 X 4 prop  It won because of one flip restarts

The reason I suggested the LA 25 to the Reading club was that we'd found in combat that the stock LA 25 and a good, stock Fox 35 were virtually identical is performance.  It seemed to make sense to extend the Foxberg concept to another engine that is also readily available and has a few other nice features.

Don't doubt it though, if you get  couple dedicated racers into it, they will learn how to fine tune an LA 25 and get more speed out of it.  Just like a stock Fox.  Careful selection of parts, getting exactly the right fits in the right spots, head clearance, squish band, etc.  It may be a little harder with the LA's though because OS makes the parts to very tight tolerances.

That and the unwanted vibration were my reasons for switching to better built engines.  I just wish that the NCLRA could have settled on one engine for their event instead of opening Pandora's box.
