F1N-150 is a nifty contest class for indoor catapult glides under 150mm wingspan (roughly 5.9 inches). These models have become popular in Europe and often classes feature many young people flying these easy to build, nice flying airplanes.
Some of these models fly remarkably well, especially considering their diminutive size:
We at J&H Aerospace can’t let Eastern Europe have all the fun, so we designed a Micro Protege to help popularize this class in the US. Josh’s model came out at 0.65g balanced for flight, and Hope’s is around 0.8g. Both fly nicely in the 24-25 second range in a 24′ ceiling. These models fly suprisingly easily. We should also note that J&H Aerospace sponsored pilot Ross Clements is getting into the low 30’s in a 40′ Cat II site.
There’s a kit too!
Here’s Josh’s flight demo, showing flight times in the mid 20’s under a 24′ ceiling:

Joshua,
I have not had a chance yet to get into a gym to fly my Cat’s Meow since my first attempts at trimming it. I did move the CG forward and in my house the glide is beautiful. I built my second 1 sheet glider and look foreword to flying/trimming it also. I put together 2 Proteges today (they came in the mail yesterday). In the house they have a terrific glide. I am anxious to get them all flying. The F1n-150 looks like it could be great fun also. If you get some kits up and running let me know and I will purchase some.
Thanks for all you do.
Jack
