EastRC POORLY machines custom parts for radio controlled airplanes, and after receiving my order for trim tab upgrades, I found them crudely cut and full of sharp edges. You cannot call them directly but have to fax or email, and they never respond. I wouldn't give out my phone number either if I made *** like this. I finally had to challenge the charge to get my money back. I am not the first to have problems-wish I would have done a better web search on these guys. EastRC.org are a bunch of crooks. Don't do business with them, ever!!!
