Thanks i am still at work and cant look at your site. will when get home. I do plan on getting your single bolt set up for sure. i might get the 30 from tower because of the 60 bucks off. I do like to support hobby shops though when can even it a bit more. i have heard nothing but great reviews about youer services. I had also thought about the 20 for tigercat. these would fly it just fine on a with a 15x10 but would like a bit more power. The tigercat will be around 25-27 lbs
