I have had at least eight different planes powered by the SAITO 30, from the Ringmaster up to the Cardinal ARF
.
I've tried just about every common prop from 9-5 up to 11-6.
9-5,6,7 & 8. (The Top Flite 9-8 wood was just too much - really overloaded the engine, the Power Prop and original Y&O were pathetic
)
9 1/2-6.
10-5 & 6.
11-5 & 6.
Older Top Flite and Power Prop wood, Tornado Nylon, modern wood in both wide and narrow blade configurations. APC and Master Airscrew plastic.
To date, the absolute best results have been with the APC and Master Airscrew 9 1/2-6. The performance is very close but if I had to choose one, I would take the APC.
Regarding tanks, I've been very pleased with my non-uniflow metal tanks but based on Bob Reeves excellent results, I plan to experiment with some plastic clunk tanks. I've just acquired two 2-ounce Du-Bro tanks.
Just my two cents.
