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.

you've built 15 arfs and this is the first one that you've noticed with built in right thrust ??

Naw, just forgot about it. Kind of like being told by the wife to take out the trash!
