Gerrit,

I'm almost done arranging a place to stay in Limmen in the first week of Juli. I'd love to come visit the flying field during that week. Would you happen to have some information as to where I need to be and what times people are allowed to fly?
Also, if there's any regulations I need to follow, I'd like to read them so I know what to expect, pay, and how to behave

This plane looks awesome! I was looking at RC Powers version of the F-22 and this one looks almost the same, but free! I am a beginner still, but this won't be my first plane. I was wondering if making a larger scale version would improve stability and slow it down. Maybe add a KF airfoil to it also. Could I make a larger version?

If I make the plane 1.2 times larger it will match the rc powers f-22.

This was my first proper scratch built, and I see no need to make it yourself more difficult by scaling it up. It's extremely stable as it is, and can fly at walking pace with my power setup ( while still being able to reach 70 kmh)

I bought 6x 17g servos at hobbyking, but I think they are too heavier for foamies (I think I bought them for nothing, because I want to do foamies and I need ~9g servos...). Well, do you think they are going to be Ok or better I wait until the 10g servos arrive?

How many servos do you plan on using? If only two, then you might be able to get away with it, but it would be better to wait for the 9-10 gram servos.

the servos are placed behind the CG, so that means the battery would have to be pushed farther forward to compensate...and often people run out of room as it is.

Better to build light for this plane.

Ok, thanks, I will wait for the 9g servos then. I think I will do the ailerons mod cause I'm a noob and I don't know if only elevons are good for me.
Btw I have bought 1000mAh 25C, nano-tech 950mah 3S 25~50C and 1500mAh 3S1P 20C lipos with a Brushless 1534kv motor. Is this F22 going to fly or it's too heavy? (I have 15-18A and 18-20A ESCs)

If you build it the standard size and using standard material (depron), it should be fine. I would go with the 1500mah and a 7x6 prop on that motor.

The optimal setup on this plane in my opinion is the 2212 2200kv motor and a 6x4 prop...and a 1500 to 1800mah 3s battery.

What motor do you guys recommend for slow flying. I would like to use a 6x4 prop and a 3 cell lipo. I prefer hobbyking also. Thanks.

My setup is well suited for slow flying, but limited to 2s.
See the links in this post for details:
http://www.rcgroups.com/forums/showp...postcount=2804

Does walking pace, but still has unlimited vertical.
I use a rhino 1050 mah, 30c battery. Cheap and light.

However, I've ordered a NTM 2200KV motor that can handle 4s, because I have felt the need for speed.

You can fly slowly using the standard 2212-6 2200kv motor, 30A ESC, 6X4E prop and a 1300 lipo. But you can also fly fast. Just because you can go fast doesn't mean you have to, and you always have the power to get out of a bad situation if necessary.

I have flown my F-22 at walking pace, or even high alpha hover using this setup.

Great vid, sweet flying plane!

I am just now starting to learn a bit about these types of planes, and our own F22 has taught us a lot... it was flying pretty well, but not quite as well as yours, but today it went down one time too many after a Spekky brown out.

So after being fixed up following a half dozen minor prior incidents, the Dollar store foam board original prototype we built to test is now totalled, but we will soon move to Depron now that the initial debugging is done!

Adds another dimension to this fun hobby!

How many servos are you using tracknoob? If only 2, how are you getting a brownout on your RX?

I think the term "brownout" should be used with quotes around it. know what I mean?
