My Ring Jr powered by an OS .15FP-S Schneurle with earlier less restrictive muffler weighs in at 19 ounces.
I can't say the total accuracy of this recently purchased ''fish'' scale, but weighing various items seems to be on the money. Just curious, what is the optimal weight for a model of this size?
Well GG, my Ringmaster Jr, powered by a PAW .080 SBR weighs 7ozs. To me,
that is optimal for the smallish 195sq" wing area. I fly it on .008" X 44' lines.
The Ringmaster Jr actually is a bit small for the PAW .080. It would fly even
better at 230-240 sq"s.
Your OS.15FP is overkill for such a small model. If you could build the full size
Ringmaster to weigh about the 18-19 ozs; your .15FP would fly it beautifully on
54'-56' lines. Or a more simple project would be a Profile Peacemaker(approx. 300sq"s)
using the .15FP for power. I have built and flown many 1950-1960's 330-395 sq" models
using .15 diesels; that includes full size Flite-Streaks, Veco and Dumas Tomahawks and
a CLC Super Clown.
