The new EFRC yak 55sps have been improved a great deal over the old ones. they have sourced a new manufacturewho has both improved the design and impored strength. i stuffed my one in from about 40 foot vertically after a threw my lipo out on some tight bunts. i picked it up, put my lipo back in, and flew it again. it is very strong. Powering it with the torque 22T/930 is great too. Its most proberbly the most powerfull plane you could ever come across, with a fully charged lipo you are nearing 3:1 power to weight ratio.

Also, they are only a couple of weeks away (dont hold me on this, i dont really have anything to do with EFRC, only [link=http://www.freestyle-rc.com]Freestyle-RC[/link], thir UK counter part). Trust me on this one, hold on for a few more weeks and you will have IMO the best 3D electric flyer out there, and there arnt many who will dissagree to that one once they have flown it
