Hi, I think coroplast is the USA name, and in the UK its called Correx. Its the same stuff though.

Does anyone have an opinion on whether you need a carbon stiffener with Coroplast ? Or do the flutes provide enough strength ?

Just swapped everything out of the old & put in the new.

You do not need any stiffener. Just run the flutes of the Coro sideways.

PM me when you're down this way. We have a regular group who fly at a local park. No rules - Just fun!

will do!

I've been trying to get to this for some time.
Thanks Tomas for sharing the F-22 plans with me. So far I have built 2 for friends and 4 of different sizes for myself. When I crash I hardly cry, easy fixer-upper.
My 24" and 28" are EDF's I don't throw them, just put them on the grass and take off. Works fine.
Thanks again
Bob

would like to see. any video??

I put together another Coroplast F-22 for my buddy - the one who has the laser cutter that cuts out my airframes for me. MIne is red on top, his is red on the bottom.

Here's what happens when you focus on having the aileron function set up properly during pre-flight - and forget to check the elevator function .......

Coroplast is VERY forgiving.

We'll get some formation flying in once he's comfortable with the plane.

Jim's F-22 Maiden (0 min 55 sec)

Hey guys,
I just finished my build. Here are the specs:

Motor: MicroDan 2505-2900 motor
Prop: 6x4 Sport/6x4E
Battery: Thunder Power 4s 2100mAh LiPo
Servos: 2x HS-55's linked to tailerons and ailerons using the posted method
ESC: Phase 3, 45 amp. I went with this one for it's ability to do 4s plus I had it laying around.
Material: 5mm Cellfoam, with fiberglass skin, airbrushed
Weight: 21.3 oz
I haven't flown it yet so if something doesn't look right, nows the time to say something I always snap a few shots before the maiden. So you can see it in it's virgin state.

Sweet...that's gonna be crazy on 4s!

Hopefully not too crazy. I'm a good pilot and I have sharp skills but I've dealt with crazy before and crazy doesn't always mean fast!

Sorry, no video. I'm in Michigan. See if this and the pictures help.
64MM EDF 5250KV Hobbypartz.com $17.42
40 amp esc
2000mAH 3s batt.
1/16 ply
epoxy and hot glue.
Short grass.

Finished the V3 F22, this time made of 4mm Correx (UK version of Coroplast).
Maiden went like a dream, with the plane feeling so much tighter and more responsive than the depron V1 & V2 I built.
Its a bit heavier but still goes vertical when needed using the same 2212-6 engine with a 6x4e prop.

F22 V3 Maiden (4 min 11 sec)

Looks good. I like the distressed bones and flames. On low rates, it shouldn't be crazy at all (with good throttle control).

I like to enlarge/lengthen the ailerons a bit, but your 'cut' should be fine.

Let us know how the maiden goes.
Then put some LEDs on it.

Regards,
Bombay
