Since this Kyosho Texan is about the 15th ARF I have assembled, sometimes i read the directions and sometimes i don't. I was building up the cowl, fitting it and all and just was off a bit. I actually thought about spacers on one side.
*Then the light bulb finally came on. So FYI the Kyosho Texan has right thrust already built into the firewall. You can tell by simply looking at it. I know WM does this but I forgot. Just a helpful tip.
