New Simla under construction in East Tennessee. YS 81 ST with Macs XL header and Rossi 50400 pipe. 12x8 Master Airscrew Scimitar. 14k RPM on 15% Cool Power. I am using this set-up on a Kaos and Dirty Birdy with good results. Figured I'd try it out on Simla as well. Wing build to start this week. Canopy is a cut down U-Can-Do.
