Upgraded from the Turnigy 2826 2200kv to the Turnigy 2836 2350kv
This is on 4s with an apc5.5x4.5

I also took most of the offset thrustline out.

but the wing wing with 2826 2200 kv will be a perfect toy

Get it from Hobbyking then. Called the Sonic 64 but same plane.

oh ya I forgot but the sonic

The canopy has become an annoyance.
Yesterday, despite adding a couple magnets to the rear it came off twice in fight, the second time breaking the prop and jamming itself in a vertical position.
Managed to pancake her in with no damage but the rear of the canopy is pretty mangled.
Ordered a new canopy from HK (pleasantly surprised this is sold as a spare!), does anyone have a clean, easy solution to secure the canopy closed?
I would have ordered one of these but both are out of stock, and my local hobby store sells them for $6 each which I won't pay on principal.

Ben - although I didn't get any video of my WW or Stinger jet here is some of my buddies braving the weather yesterday.

Wintertime RC flying March 2 2013 (0 min 57 sec)

While belly landing on snow is pretty cool wish I had bought skis for my P-51, they were having a blast taking off and landing on skis.

Today a bud used his iPhone app that uses the Doppler effect to calculate speed.
Did two WOT runs, both came back at 77.something mph.
This is with Turnigy 2826 2200kV motor, APC 6x5.5 prop, 1800mAh 40C 3S batttery.
Plenty fast for me!

Much appreciate for the effort! First time I have seen an F4 on skis!!!

That F4 looks wicked on the ski's
Kurt it's surprising that you only got to 77mph with that setup.I would've thought that motor would get it to 100mph atleast.what sort of flying time do you get?

Same here! It's one magnificent beast

According to an online calculator , with 4V/cell @2200kV it should be spinning ~21,000 rpm (80% of theoretical top rpm of 26,000?) so the prop pitch speed would be ~110mph.
Although the WW is pretty sleek there's still quite a bit of drag with the big wings so the actual top speed would be less than this, but yeah I'd have guessed a bit higher as well.
That's assuming the iPhone's speed is accurate, but at least both runs were pretty good i.e. running straight across the iPhone's location, full WOT starting ~200 yds before and not turning or letting off until ~200 after.

In any case the little Wing streaks out of sight plenty quick enough for me

Flight time: 15 minutes with a Zippy 1800mAh battery, 3.7V at the end and took back ~1200mAh. Granted I was doing more slow, low flying than WOT blasting but that's still a long time in the air!

Nice job!!
What model flight stabilizer are you using, and how do you connect it with elevons?
I have a HK i86 that I'd like to try out on my WW, just not sure how to hook it up - it has ail, elev, and rudder inputs.

my wing wing ready for evening/night flying

that's awesome
What LED's are you using?

Re:speed
it makes sense,but hey that's plenty flying time and 77mph is not a bad speed at all though

I use a magnet and also a cut off screw that engages a hole I have put in the end of the compartment (the black bit is a bit of heat shrink). Excuse the debris, just back from another crash.! (the canopy stayed on)

thanks lobber -
I also have a post in the front of the canopy: ~1" CF rod that fits into a CF tube glued into the nose. It was the back end of the canopy that kept popping out, somehow. Air pressure from the holes in the bottom front (that I'm running a velcro strap through to hold the battery)?

A buddy has a couple extra spring-loaded canopy latches that I'll probably fit to kept the back part down, when the new canopy arrives from HK.
cheers!

One idea would be to make holes on the back of the canopy as an exhaust to release the air pressure. My canopy always stays in place with just a simple velcro in front and the snap-on clip at the back.
