The 2213 can make just about the same thrust!!!
My test prove it. Apc 10x 3.8 will make about 7,600 plus rpm's making about 38 oz of thrust!!
The C 35-30 kv 1100 will make 39.2 oz running a Apc 10x3.8 at 7,600 . So why carry the extra weight?
This setup should be running a speed prop. So you might try a Apc 10x 5 it makes more speed then the 10x7 because it turn a lot more rpm's ..About 8,400. or so!!
PS: that's about 40 mph on level flight.
I'm running about 60 mph on level fight!!
I am running a 10x7 APC speed prop. My calcs show ~250W output and 60mph and 61 oz thrust at WOT. However, I will give it to you that I haven't tested anything. These are estimates for the figures stated by Turnigy. And through reading the tests on that company, they are not really built to a tight tolerance. I will remember your advice if I rebuild.

Calc attached:
Propeller 10.0 x 7.0 Geared 1.0

Volts: 11.0
Amps:29.8
Rpm: 9616
In: 327.4
Out: 254.8
Eff: 77.8
Time: 2.0
Thrust: 64.7
Speed: 63.7



Thanks,
Hebert

Edit: my motor only weighs 3/4 oz more than the one you suggested and I get 50W more output.

Ok I haven't been able to find a cameraman yet but here are the specifics on my build.
AUW 13 0z.

motor Hextronics
Kv: 1300rpm/v
Max Load: 8 amps
No Load Current: 0.5A
Suggested Prop: GWS HD-8060
24 grams

Prop GWS black 8060

battery
Rhino 1250 3S1P 20C LiPo Pack

ESC TowerPro 30 Amp Brushless Speed Controller

servos pico+ BB

Plus three pics, she still needs a little finishing. Maybe some paint but none but one I have built so far have lasted long enough for paint. The one that did get painted was because it hung in my home office for 2 months and I got tired of hearing my wife complain about that chunk of foam.
Will try and get some video before dark if possible.

I run the same "Blue Wonder" motor and prop (HD8060) on my Simple Delta and it really zips around the sky. I use a 500mAh 3s lipo and the motor never even gets warm. Hobby City now even has a new version that I have on order...the "Red Wonder"

It gets a little warm but not hot to the point you can't touch it. The guy I bought it from recommended the 8060 prop with the 1250mah lipo. He runs one set up exactly like mine in fact except he has a lower amp esc on his full fuse spitfire. By the way check out his website karglusa.com, tell him Jack sent you by if you decide to buy.

I actually have a blue wonder and am about to go and try to maiden the thing now in a micro UFO. I just never knew it could fly a plane of this size.

I'm knew, I'm still soaking this stuff up like a sponge

I'm curious to see how it does on this plane as well --- it seems like it would be underpowered. Then again, at 13 oz, this seems like a nice light build. I'm running the 1500kv Blue Wonder on Swift II wing --- with an 800 mah 3s at 10.5 oz auw, it goes straight up.

Hey Rabbit I'm soaking to. I've got the same motor on an f22 with about a 32 inch span built off of http://rc.tomhe.net/f-22#toc10 this plan. Here's a short video to give you an idea how good this motor is, winds were about 10- 12mph.

BustedBlades. did you use a tach to get those numbers?
I can't get anywhere close to those high numbers using my same motor with a good high power batteries. ( 9616 rpm's Apc 10x7??)
I just run my test again with a new Turingy C35-30 kv 1100 with a New Apc 10x7
I get 7,800 rpm's = 33 oz. of thrust and about 159.6 watts and about 51 mph.
I'm using real numbers here from a amp reader and tach,not what some company says there motor will do. I don't see how your motor could be turning about 2,000 more rpm's running the same prop.
Your not running a 4 cell battery are you?
I'm using Thunder Power V2 2200mAh 3 cells. For test, not on plane. I run a Thunber Power 1320 pro-lite on plane. And that battery is not a very high C rating battery.

Not bad with that little motor. Here is a 32" F22 with Power 25.

I don't like the 1300kv Bw at all! Same plane will fly at half throttle running a Bw 1500kv instead of 3/4 throttle running a Bw 1300kv with the same prop. So I don't buy the 1300 anymore!

Great video, that thing is pretty quick, I kind of like the slow flying right now as I am just getting my thumbs limbered up, and thats kind of hard for us old guys, especially when you've spent fifty+ years mistreating your hands doing mechanic and carpentry work Ouch just remembered one time I almost lost the end of my throttle thumb due to a framing hammer hit.
