interesting design on the Northrup, no surprise it never made it to production, tailless wings are just too much without computer assistance.

i've built a slightly larger version, 8" span, and re-installed the electronics on it. interestingly, it didnt want to climb much, like your larger one, neurotex. i think it had more to do with the CG and canard angle, after a crash, the canard was at a very high angle of attack and i flew it that way and it climbed very nicely. the lipo is recharging right now, so i'll see what happens when its charged and ready.

bummer about the forward swept version. maybe a more traditional approach with some major reflex in the TE and LE would help stabilize it enough. wouldnt be suprised if it needed an oversized rudder to help calm it down too. i suppose i should finish the Fling first though

googledperson,
the Fling is a pretty straight forward build. only takes a couple foam dinner plates and some foam safe glue. the AlleyCat has been built by a number of people over on RCG, i havent built one myself, but it looks pretty straight forward too. the plans can be found in the plans section here: http://aatoolbox.no-ip.org/ speaking of the toolbox site, Chris is working on a "master toolbox" page where the AA, Picco, and the Silverlit SingleWing mods can all be accessed - http://www.rctoolbox.no-ip.com/

edit: woohoo, she flys! bit more stable than the smaller one, climbs well enough, and the turns arent so bad now (though a right hand turn causes it to lose some altitude). she cruises along at a pretty good pace, at one point i had it high enough that i made a hard left turn, and she rolled over and looped! AUW is now at 7.8 grams, i'll try to get some video. nice design, Neurotex...you know if you dont enter this into the foam plate cook off, i'm going to have to, right?
