The plan supplied with the kit is not good at all and if built from that would end up VERY heavy.I basically did my own thing so that it ended up light(once i have finished covering it i will pop it on the scales)but its at least 3lbs lighter than it would have been had i stuck to the plan.
I am still worried about its flying qualities but i guess thats normal.
For GOOD plans have a look at the ones available from the rcmodeller magazine.
