We-ell, I decided that I was going to build the same kit. It was my FIRST attempt at building, but I've always been good with my hands, and follow directions well, so I thought the intermediate builder's kit would be okay.
I started it about 7 years ago, and after 250 hours of construction I burned out on it. That 250 hours brought it to the point of being ready to do the plastic stuff and start covering, but that's where it sits today.
And yes, that 250 hours is very accurate because I kept a log by writing the time it took to complete a step next to that step in the instruction book.
It's a good kit with terrific instructions, but unless you're retired and willing to spend 50 or more hours a week at it, I doubt you'd get it finished by July. (I've estimated that it would take another 100 hours minimum to finish mine. [&o])
Now, if you really want the Top Flight Cessna finished by July, I might be persuaded to part with mine, but I don't work cheap, so....
Good luck.
