When a born again Gear Head finds a box like that, a good time is at hand.
I just finished running the 50 for one hour on approximately 8 oz of fuel, report below.
Saito 50 made from used and new parts including RJM ring,
Fuel====Wildcat 10% with 18% full syn,
1st prop====HY 12 x 6==rpm===9,810
2nd prop====Xoar 12x6==rpm==10,100
Idle for both 2,400
Plug===Sonic Tronics/Glo-Devil 4c
The conditions are poor for a picture.
The 50 is very smooth at all rpm.
