OS .46AX vs. Evo .46
In the February issue of R/C Report magazine, the publisher, Gordon Banks, did a test on the Tower muffler, showing the rpm gain over the stock muffler. He used 3 engines, OS .46AX, Evo .40 & Evo .46. I assume that like I did the first few times through, everyone looked at the gain in rpm from using the Tower muffler. Look again at the rpms of the engines on an 11-6 prop. 1,000 difference between engines. The AX was turning 1,000 rpm better with an 11-6 prop than the Evo .46. Anyone else noticed this big a difference?
