Freewing 90mm F-22 Raptor - Official Thread

Some things... Take your landing gear struts and put loctite on the set screws on both sides of the pin, the strut side and the retract mechanism side. I don't remember if I ground flats on the stab pivot rods where the wheel collars go to hold on the stabs but do put loctite on those set screws too. Glue on the nose cone, the magnets don't hold it on good enough.

The mains have an odd spring loaded knuckle that makes high speed ground handling odd, a steering specific gyro works wonders (Assan).

Everyone has their own radio set up but tailerons really work well on this plane. You'll get a lot of opinions on full span this and that, 8S, 10S, and 12S set ups and different CG points. The stock 6S isn't bad and the book CG is a good start.

For looks, please paint the rudder servos grey. :)

Its a great plane. good luck when you maiden it.

Oh yea! There she is!

Hi everyone,
Just received my new F22 from Motion RC, I ordered it Wednesday morning and received it by 3:00 the next day! Thanks Motion!! Like most say I put it together in an hour but will probably take at least a couple of hours to get the radio and everything setup. At 600$ plus bucks I want to take my time setting it up but this thing is a beauty and can’t wait to get her in the air! Just one question has anyone done any weathering to there Raptor? Like to see some pictures if possible. As my normal process is to fly it before doing any modifications. Thanks!

Congrats on the maiden!

And greetings from Norway! ^^

Hey air Guardian I finally planted my su35 after years. Freaking sun blinded me. Instead of another su35 after years I decided to go with the f22 6s jp hobby fan. Just ordered it today. Tough choice between this and the MiG 29, something about that MiG that doesn't get me excited. I know you've been flying it a lot lately. Probably get another su35 at the end of summer.

Ouch, too bad, sorry for your crash!
You'll love the Raptor though ;)

I also planted my EF-18A due to getting sunblinded... :'(

[ElCid]

Finally got my maiden in today, and wow what a great flying airplane. Pulled blue box out in favor of a 12 channel reciever, and took my time on the bench setup. The end result was a plane that needed ZERO trim. I do have to say the stock throws are a bit much for me so i will be taking 10-20% off of both high and low rates. Next few flights i will get the gyro setup and activated. This thread has been hugely helpful!

Some folks cant resist in rc air hobbies to be tools. They think they know it all and they are special. I met many flying 3d rc helis for years with the best in the world. Remember its supposed to be fun and everyone has at one time been the new guy with many questions. Just cause you think its redundant doesnt mean it is for others.

[Airguardian]

It was high time for the F-22 to get some quality 'air to air' treatment...

[ElCid]

it will do the job,.I was hoping for a quick flight tomorrow and I went back down and played around as you suggested but the flaps are just too off to be safe for a maiden.
I have had zero issues with my 80mm A-10 or my 90mm F4 from motion but one out of 3 aint bad.

[Evan D]

Sounds like you’ll have a great set up!

[ElCid]

but in this case separate channels is the better approach so you can do crow, full span flaps, ailerons, tailerons and rudder airbrakes… I have all that plus TVs on mine.

Yea i do like doing the programing so it will be fun. I run a Jeti DS-24 and with this i am going to use a Jeti EX R12 Assist (Gyro) reciever so i have plenty of channels.

I just picked up the led controler from Motion so the landing light is covered as well and my Truefire will be here next week so i guess i can wait a few days.

[Evan D]

Or landing light. I do have to say that I have been able to fix exactly what you have by doing things I’ve said, making sure they are the same at half flaps and changing the locations of push rods (where they are on different holes on the servo arm or surface horn). On some where the horn is screwed through the foam tightening one screw more than another to angle the horn or both to shorten the leverage arm works too… just have to be creative.

[xviper]

I wish it were that simple but unfortunaly its not the case. Please see the attached, both servos are "Centered" and the flaps channel is centered. Moving the control arm one spline righ or left still resutls in the servos not matching. One of the servos is off.

I presume that because you have the servo horn screws removed, that you did try to clock the right one to the left one tooth? That didn't put it more 90 degrees?

[ElCid]

Since they are on the same channel and oriented the same way there is really no way to get them alinged from a throw perspective, they will never be the same. I am going to wait and hear from Motion but in the mean time i am going to rip out the blue box and wing connector cables and do a straight run for each servo. It will be fun doing the gear and door sequencing. The upside is there will be no gear delay now.

[Evan D]

Let me saw also that I usually set up flaps at half flap with the arm 90 deg and surfaces even. A tiny bit off up and at full flaps is better than zero, a little and a lot.

10mm seems like moving it a hole could correct it.

[ElCid]

Well this is the plan, but i wanted to fly it a bit before removed the blue box and started running my own servo wires. I might just go that route now anyway, i have a 12 channel reciever free from a prior aircraft.

I only got it today and was planning on the maiden tomrrow am :(

[Evan D]

Most of the time I can fiddle with things and get the same travel. Sometimes I have to putt he two in separate slots and use a mix with sub trim and throws to match them. On my F-22 I have flaps, ailerons, stabs and rudders all on their own separate channels anyway.

[ElCid]

i can deal with the rudders being off a few degrees, but the flaps at full the difference is 10 mm and thats just huge

[Iamrcpilot]

I had the same issue with one of the rudder servos. The end point was off on one. Motion set me a replacement servo.
