Thanks.
Are you new to flying at all? Or just new to flying wings? If this is your first foray into rc flight at all, I'd say the Albatross or pelican are great planes to learn on, and you'll still enjoy them when you're experienced too.

If you've flown before, but are just new to flying wings, then considering you said you have limited space, my opinion would be a lightly built assassin. It's probably the toughest wing in the world, and will take any abuse you can dish out. It responds well, glides well, and can be pretty zippy when you want it to.

The reason I wouldn't say the scythe is just because it's so responsive. Even built light, and with very small throws in the elevons, it's just a little squirrel of a wing, and will turn on a dime at your movement of the stick. Not incorrectly, just quickly. I find my scythe is more work to fly, and my other wings are more enjoyable.

No Doppler or radar available for now. I heard there was an iPhone app? If someone know of one that works let me know. Best guess is 60 mph+?

Loved the almost snow dart move there, reminds me of Dave's touch and go he did with his.
I don't know when I'll be out that way in the near future but if something comes up I'll get in touch for sure. I get out to Santa Maria a couple times a year but cut diagonally across to get there. I usually pack a plane when I go but seldom get to fly it. Trying to find the time and weather when I'm down there to get some AV over Pismo Beach.

Does anyone here already used the APP for Iphone called Speedclock? Did it worked to measure the wing speed?

You are going to laugh but if you can get some good video of low straight passes over your head on video and post it on youtube I can doppler your speed off the video.

I can try. You mean, plane coming at me, passing directly over-head and going away. Stationary camera position or will hat cam work?

Sorry, your discription is probably good enough but figure I would ask since for it to work I would guess you need a pretty accurate video clip.

EDIT...

just bought the app posted above, has mixed reviews but for 2 bucks... it looks like something to play with.

I'd run it without worry.

EDIT...... rechecked the motor specs for the Zoom 370. says 24 amps max. I might be pushing it with this prop on a 3 cell.
I see a few other guys running the same set up, 24-25 was the draw at full throttle if I back off a little it will bring it down so I think I will adjust the throttle end point. From what I hear it is crazy fast at full throttle anyway and I really don't need all the speed. We'll see its only a 13 dollar motor, if she blows she goes!! Thanks for check on this for me

I think I'm the 1st to start using this motor and it's up to 20-30 flights now at mostly WOT and working great. I'm sure in flight the draw is lower then at static. No heat issues with any of ours. I like it.

I found that a APC 4.5X4.5E prop is almost as fast and draws 20 amps and was something like 225 watts or so power on a 3 cell. I went back to using the APC 6X4E and that is what is on in the above video. The 6X4 was showing 300 watts output. For reasons I have no clue about an APC 6X3E draws even more amps than the 6X4 and was something like 350 watts. that one might burn out the motor but I think that Blu is correct and the 6X4 won't hurt it. My readings were with a fresh fully charged battery too. I did pick up the Power Up Zoom 400 to swap out but have not done it yet and may not. If I was buying for the first time, might get the 400 if speed was my main concern. It's only like a buck more. Heads Up has cheap shipping (USA) and has gotten items to my door in 2days after ordering. Excellent vender!

That is why we can recommend the same motor, ESC and prop for our slow fly puller Albatross as we do for the pusher Assassin and Widowmaker. The parts are all the same it is just how you set it up.

Is there no concern with what side of the prop has the "precision" hole?

In regards to the 370 zoom motor and 6x4apc, I don't have a wattmeter (I know...) but my 370 comes down very hot after pushing my jet around during a 3min flight with lots of WOT.

The backplate is hot enough to burn you. Even with a 40A esc. I'm looking for more speed and wonder if propping down might help. I'll be watching this thread and blu's antics. Love to see that 400 zoom be put to use, or perhaps some 4s action. Heheh

You set the amp draw of your motor by the prop you use.

It hasn't been a problem on the insert with the precision hole on one side of the prop. I often don't use the inserts anyway.

If your motor or ESC or batteries are running too hot use a smaller prop.

One inch of diameter is about the same as 2 pitch so an 8x4 is about the same pull as a 7x6.
