Easy to build foam scratch build, the F-22 Raptor is a great design for a fun easy to fly RC plane, and it also has great trainer tendencies. 

Watch this RC plane in action in our F-22 Raptor Review Episode here

 

 

TIP for printing the plans: 

To print "tiled" use Adobe Reader X and in the print dialog select "POSTER", select "Cut Marks" and make sure "Tile Scale" is 100%. Then overlap and tape as required (after trimming the top overlapping edge).  

(Thanks youtuber larrybarrick for this suggestion!)

Hey Brother, thanks for the video, but when talking about scratch build I would really see more of the construction process and less of your face talking. I'm a beginner on the R/C hobby, and want to start doing my own scratch builds, but your video is not helping much.

Congrats for that present for your kid, btw, how old is he? what's the appropriate age to start your kids on the hobby? I mean, you have been in the hobby for many years and I bet you've seen many kids hopping on this ride, so what's your suggestion?

Thanks again.

Hello friend.

Thanks so much for the input. I will certainly apply it in the future. Our goal is make building these little gems as easy as possible, and your input helps. Both of my boys are flying the f22. They are 7 and 10 (but they have been flying for almost 2 years. Five is a great time to start if they show interest. It is more bonding than teaching though. Flight sims are what my boys loved the most. It took the fear out of learning, then I followed up with buddy box time!

All the Best!

In addition to everything that jdgomezb has said, could we also have some more specs on these pages, such as whether motor angles and control surface travel for us beginners, because I still haven't worked out if its needed, and how much is required for a smooth flight. maybe even a 'flitetest - fast tip' on this?

Thanks for all you're doing.

This plane looks great and I am building one out of 6mm depron with this motor with a 7x3.5 prop and 12A ESC.

http://www.giantshark.co.uk/cf2805-2800kv-brushless-outrunner-motor-p-213.html

I am hoping the motor is not too powerful at 2800KV and that it will fly nice and fast :-)

I am also thinking about doing a version with a small EDF unit.

Gomez:

Since you're new you probably haven't been haunting the forums at RC Groups. Try that. Also Ed at Experimental Airlines is very thorough and can give you some good ideas.

Your comment about Josh's face seems innapropriate to me. Perhaps you didn't mean to come off like that. These guys are seriously first rate, and this is the best RC site on the web. They offer heaps of top-quality content for free. That probably has earned them a little respect, don't you think?

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.

C of G

Where is the C of G on this F-22? and from where is it measured from? In the video there are some figures given but he doesn´t say from from where the measurements are, i.e. from the "Leading edge" or from the "nose"? Can someone please throw some light on this on? Thankyou.

hi i am lead to beleave its COG is 16" from the nose

http://www.rcgroups.com/forums/showpost.php?p=8145735&postcount=6

on my plane cog is at this point glides nice but when powered nose dives i had the motor pointing up to the sky 2 degs thinking this was up thrust but waching flitetest video it called down thrust so going to try and move the motor facing the ground 2 deg see what happens :) i fitted my with kf2 wing aswell

papabearflying June 11, 2012
Hi Shaddow12! the Kf2 airfoil is always a super idea, if you change the motor angle downwards you will have the same problem in reverse! I had my motor too far pointing down on an RC Powers F-22 and had to pull the stick back the whole time :-( Try moving the CG first, that will surely be an easier way to go?
You have your motor on correctly, just look at a Bixler or Easy Star all of them have the motor pointing upwards, on the Easy Star it´s too far up.

shaddow12 June 11, 2012
thanks for that tried playing with cg but the sam as you had to pull stick back all the time i have a plane like the bixler as you say motor is upwards but there nothing around the prop if you know what i mean on them as the f22 has the wing there as i said before i watch http://flitetest.com/articles/Motor_Angle_and_Thrust_Vectoring_Experiments
witch mad me think off changeg to the motor pionting down to the ground plus the prop was should push down on the back of the wing giving lift? i quite new to this self tort 3 months lol

We just mounted the motor straight and trimmed the elevons to fly level. The CG was in the middle of the motor mount. That's where Josh's thumb is in the video image above.

Just built one and tested it. The balance is 1 1/4 inches towards the nose measured from the front propeller cut out. Another way to measure the balance is 16 inches from the front nose back.

just built my f22 and test flew it today cg was in right place but i had to keep full down elevator to keep it flying level when i landed it both elevator were level to the wing. any body know what might be the mater with it , i have got 2 deg up thrust

Hey,

I am new to the hobby, and would be looking for this to be my second plane. I have never scratch built before although I have a small experience with electronics. I was wondering a few things...

Firstly where do you get the foam from? I would like to use the same foam just for ease and there wont be the worry that it wont work...

Secondly, would a 3 cell 2200mah 25c battery work with this if I used the right esc? As I dont want to put money into more batteries...

Thanks very much and happy flying,

TehMaxwell

I believe the commonly used types of material is dollar tree foam, ADAMS foam board, Depron, and foam from a local home improvement store (stuff used for insulation).

I don't have a ton of experience but I do own a 3 cell 2200 mah lipo as well and know that it is significantly larger and heavier than the ones used here. As such there will be issues with CG (center of gravity) balancing as the placement is already close to the center. Plus with an increase of weight replacing the 500mah lipo the motor (depends on which one you choose to use) may not even have enough thrust to lift it properly. In regards to the esc you'll most likely need one that can support the voltage and cell size and the amp drain caused by the motor.

Hopefully someone more experienced can add more precise input, but from what I know this is what I can come up with.

Greetings. Has anyone built the 32 inch version of this. I have just about completed it and now of course I am trying to scale up the power specs to match. Any suggestions would be much appreciated. BTW. This is the first build that I have done where my wife said Wow - is that ever a beautiful plane :-) Can hardly wait to get it in the air.

I just built one of these - but my transmitter doesn't have a mixer built in.. so - I have a Blue Arrow V-Tail mixer. Here is my question - how can I adjust the deflection for elevators vs ailerons? many V tail plans seem to call for different 'throws' for these two channels? I also noticed that the Blue Arrow doesn't seem to center the same each time, so I'll switch to a HobbyWing mixer. Any Suggestions?

Hi being new to the electric end of the hobby I built the f-22 using the exact same components as speced above and for some reason I'm only getting about 3 minute flying times... Is this normal because i would like to get around 7 to 10 minutes
Log In to reply
einar.zenka.3 April 20, 2013
you have to do a simple calculation (battery mah x 60 )/motor draw
^^ usually in amps ^^
convert amps to mah ex. 9 amps = 9000mah
Example:
battery - 500mah
Time - 60 min
motor draw - 9 amps
(500x60)/9000
500x60=30000
30000/9000=3.33
so your flight time would be 3.33 minutes give or take a couple minutes

Anyone ever screw on the stock Dynam HawkSky motor? Just finished with the main build and now have to figure which motor to take off tje shelf! I believe the motor is a 2200kv swinging a 5x5. Seemed plenty strong pushing around the hog that was the HawkSky!

As the engine is point backwards, do you use a 'pusher' prop or just fit a 'pull' prop the other way round?
I am just building one and noticed the prop did not fill too well on the prop saver when reversed?
Also, assume you wire up the motor to spin in the opposite way?

Can't paste my photo of the fuselage. Back to drawning board. I appreciate you guys,
