I purchased the Roban UH-1N Iroquois 600 Size Helicopter - ARF BUNDLE back in May 2019 and I'm finally getting around to assembling it in June 2021. I've been busy... lol Anyway,,, The included spacers, main bearing blocks and tail bearing blocks have me confused. I am using the Roban replacement frames which is pretty obvious, however the "Trex" main shaft bearing blocks are 53.5mm wide along with one "Trex" knockoff spacer. The Roban tail drive bearing blocks and the other 9 included Roban spacers are only 47mm wide.
The thread in the Hobby Squawk forum is kinda useless when it comes to the frame assembly. I have found a lot of frame images around the web and as best I can tell all of the bearing blocks and spacers are supposed to be the same width. i.e. either 47mm wide or 53.5mm wide. I've been doing the heli thing since the early 1980's and this has me stumped. Am I missing something?
Thanks...
Fred
