And here is how that turned out:

You can see the skewer spar in the center of the 2 halves...

With the top layer of the KFm wing in place, covers up the spar and strengthens the wing. I am trying out the Gorilla spray adhesive this time. I found when I sprayed directly to the FB it wetted the paper enough to bubble it up some, once glued on it wasn't an issue, thinking of it now though next time I will be removing the paper from the contact areas to see if there is a better bond.

So I looked through all the mighty mini jets and the f-22 ticks the most boxes... like the rest of you I don’t really don’t like the idea of all the extra weight in the removeable wing, so I’d like to do a fixed wing. I love inverted flying with these jets and the airfoil on the alpha/bravo would make it a bit harder to fly inverted than with the mini f-22 with a flat wing. The ft website says the bravo is the fastest and most challenging to fly, which makes it appeal to me. @SquirrelTail said the alpha if he craziest though. Is there a difference between crazy and fast? What do you all think I should do? Until my rc gets back, I’m stuck with 3 channel so unfortunately I can’t fly my ft-22 for a while, and a mini f-pack triblade prop jet is pretty appealing! 😋

I think the Alpha is the most maneuverable, the Bravo is the fastest in a straight line, and the Charlie is the most stable.

From my experience with all of them, the alpha is most maneuverable and does everything you throw at it!

Do the Bravo, you already have maneuverability with a slower 22, push your speed boundaries and see how fast you can get the Bravo to rip past ya. It will scare your the pants off, and then you will want more. Like a drug

Have you built all 3 or know someone who has?

 

[BATTLEAXE]

Belly pan done:

I noticed om the 22 that the front edge of the belly pan is susceptible to abuse from landings so I reinforced the hell out of the leading edges as you can see the skewers frenched into the inlets. If you look at the plans just in behind you can see how I did this, there are also skewers along the bottom of the side walls to stiffen the whole thing up.

I have owned B and C and flew my friends A a whole bunch

Ok, well bravo it is then! Should I get a 4s? Lol - would need another esc, which I don’t want to buy right now. 3s should be a screamer though!

Go to 4s after the 3s maiden

EDIT: If your going for speed you could try to lower some drag by getting rid of the "intake holes" and ditching the undercambered wingtips.

@Headbang what was the amp draw on your 2205 red bottom emax f pack motor? For 3s and 4s. I plan on using a 6x4x3 prop.

 

[The Hangar]

Gotta get some more foam board. I used my last sheet for my ft pietenpol...

That would give you a better bond, expreince talking.

@BATTLEAXE great thread you got going here. I haven't had luck with the Charlie yet, broke two already. I am dying to be able to fly any one of these birds. Matter of fact I still have the wings from the Charlie intact just need to build a new fuselage for it, so I am temped to join in . Might try to change the fuselage to fit a B pack motor. Think it will work with this type of plane or I need something with more Kv to it?

 

[BATTLEAXE]

This as far as I got so far:

The pieces are actually fitting together, this is the first time I have done oversized plans and it's working out really well...

This nose piece wasn't easy, had to glue the top and bottom sections an inch or two at a time each side till I got to the back of the top piece. And to keep it centred, I hope I don't mess this thing up on the first flight lol. It all fits and is pretty much ready to all be glued together, just got to make a pod to fit the firewall and it should be good to go.

If you build it light, I don’t see why it wouldn’t work. You would need to enlarge the whole plane or at least the prop slot to fit a 9 inch prop though. @BATTLEAXE said 135% fits a 9 inch...

I am running the C pack on mine so it will at least run an 8x6. That's the nice thing about stepping up the motor size, even with a lower Kv you can run more pitch. More distance per revolution. The FT-22 I built was the C pack as well and it flew nice and fast. This is a little bigger airframe then the 22 so I am not sure if I will get the same speed out of it but it will fly awesome.

I35% fits the 9"
122% fits the 8"

Come on join the club, we don't bite.

Speak for yourself! Lol

Lol - are you building one?
