Thats really good. I'm using the same motor but with a 22amp esc, 7x4 prop. A 500 3s 20c pack only last like 4 minutes at 3/4 throttle. A 800 3s 40c pack last about 6 minutes. I'm going to have to check if I have some weak batteries.
My total flight weight is 14oz (394 grams) so I'm on the heavy side I believe.

Hey i have the parts for the f22 raptor and i was wondering. that when i go to land the plane. if i might break the propeller, because it could stop perpendicular to the plane or facing up in down. or will the propeller always stop the same way you put it on the plane. Also how thick of foam should i get for it.
Yeah the propeller might break. Use a prop saver!

hey i am building the raptor and i need to know how thick of foam to get
Dollar Tree foamboard works fine works fine.
Blue fan fold works fine too, is 1/4 inch.
If you downloaded the plans from here:http://www.rcgroups.com/forums/showthread.php?t=740049
It was done in 10mm foam
The thickness isn't critical
Use whatever you can obtain inexpensively

BTW- I haven't tried this stuff but looks to be a good alternative to buying fanfold foam.
If you live in the states it may be a good deal.

Hello guys.. I'am new in this.. I build Raptor F22 with 50cm wingspan.. can I use 1400kv motor and 3S 1300mAh battery ?
I have build that and it look like to heavy.. Can you give me some help please ?
Thanks for the answer
A 1300mAh battery is sure heavy for a 50 cm wingspan F-22. I would use nothing bigger than a 800mAh, prob a 500mAh.

What's the connector on this battery? (same as the one FliteTest used)

That red connector is a JST.

Darn, wish they had JST extension cables at HK. Should there be any reason to change the JST plugs to other plugs?
XT-60 plugs are quite heavy for small planes...

That's what I thought too. Where do you guys get your JSTs?

Will this setup work? Still not too good at these things.

Sorry, missed your post
That is a great little motor! Run it with a 7x6 prop - but then you'll be pulling a bit more amps. With the RedBrick ESC's, it's best to go over the required numbers. The FC2812 will pull around 15 Amps with the 7x6 propeller, so I'd choose this ESC instead:

Now - that is a slightly larger motor than suggested, so you will need a slightly larger battery too. I'd pick this one:
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=11901&aff=524347
That will make your Raptor a moderately easy to fly plane with plenty of power!
I'm currently running that same motor with a apc 7x6 prop. I'm using a 22amp ESC and it works fine for me. I Definetly would go with at least a 800 size battery! On a 500 I only get like 4 minutes of flite time with 3/4 throttle.
That motor and prop combo will send this plane verticle easily.
As far as the ESC colorex could be right with upping it, but I've also read only to go a couple of amps over the motors max amp draw, otherwise you can burn your motor up with too big of a ESC. But I'm still new at this and figuring things out myself. So read, read, read!
