You should be able to do it in 2 weeks. I did mine in 2 1/2 weeks and worked only in the evenings for a couple hours. Everthing seemed to work well with no mods.

Just flew mine for the first time yesterday. Flew well hardly any trim needed. Difficult to describe its performance as of yet as there was hardly any visibility at 6:00 yesterday afternoon and in about 15-20 mph wind. Can't believe i took it up in the first place. Only real point learned last night, wind knocks that thing around like a monky on crack!!!

What size tank are you guys running with the OMP 540? I have a 6 oz and don't get much flight time with a TT .46 and MCP.
