I got out for some "spring flying" on our hill after work today, 37 degrees 18 mph wind and snow...Yup I Love New York

Had one to maiden,cant say it went well.
Acted very tail heavy added a bunch of nose weight,barely flying ,conditions were not fun and tired after a full work day...I will get back to it

Then I put The Knife Edge up
This Plane just kicks Butt !
spent the next hour or so ripping with it,gusts that rocked me on my heels ,crossed and bumpy ,sink, snow ,grovel you name it the KE just does it .

Flying it in close on the top of the hill and standing it on a wing tip , pulling elevator to do a paper clip turn ,it seems to accelerate thru the turn like it was shot out of a canon,I think it is the flex in the wing loading up and then unloading like a slalom ski.....
Great way to end the day

It's been a good while since Gearbest have had any good quad specials on, I noticed their website has improved so maybe that is where the focus has been. Anyway I've posted my pick of specials below at http://quadifyrc.weebly.com/coupons-and-discounts.html

I like the fact that both the TX200 and an OEM CCD micro camera are both on special meaning you can upgrade your AIO camera in your brushless micro to a CCD cam with variable power vtx for less than $30. More details on this here for the leader.

Emax BabyHawk R for $122

Tattu 3s 450mah battery for $9

Tattu 3s 850mah battery for $12

Tattu 3s 850mah battery for $16

Leader 120 PNF 2.5" brushless quad for $110

Full Speed TX200 25/200mW VTX $10

Furibee MS Micro CCD Camera $18

HAKRC 20A 4in1 2-4s 20mm ESC $17

Whoop pro f3 light controller with OSD $18

Emax LHCP pagoda antennas (pair) $5

10mph in modified flip flops (3 min 37 sec)



Was quite pleased by how stable it was at 10.9mph. For most of its life, it couldn't go straight at 10mph, even when completely empty. It now goes straight even with a camera pole on it. Better living through FIR filters.
