just reading your thrust/weight ratios.. I have a Mirage delta wing jet with a OS91/ramtec im installing this week.. the plane weights 9-11lbs dry, and the ramtec puts out approx 12lbs of thrust.. should this setup be able to go vertical on take offs?, dont know until I try.. btw this is my first jet, tried to fly it once before with a k&b.45/turbax setup... was underpowered.. so I havent attempted again, unitl NOW!! [:-]

thanks for the info...
