New to this Crawler hobby but I am excited to learn! Rebuilding a Wraith Transmission to upgrade to metal gears. I purchased the Robinson 1541, 1545, and 1555 for my Wraith. While looking on the web afterwards it appears that the correct number for the idler gear should be 1551? The hobby shop assured me the 1541 is correct. What is the difference between the 1541 and the 1551.
Thanks for you assistance.
