dude........check this out. If you want an excellent IMAC plane and 100 inches or so is what you expect to get then there is no other choice but the Composite Arf 2.6 meter Extra. You can get one for around $1000 and there is no building to do. It is a fiberglass composite "shell" with carbon fiber reinforcement......if you hang a ZDZ80 on there you could come in under 22lbs depending on the equipment you use.
the website is
www.composite-arf.com
the NE regional rep has one of the Jason Schulman shemes for sale right now for 20% off due to a couple of really small imperfections. If you would like that plane let me know and I can have him get in touch with you.
either way, like I said, in 1/3 or so scale size, it is the only choice dude!
I know it isn't a kit which is what you are asking about.......if you really want a good kit I suggest
www.aerotech-rcmodels.com or maybe an Aeroworks kit, they are nice.
