I tried a few 13x4, 12x6e and 13x6. In end I am sticking with 12x6e.
I get better flight times and speed. The climb rate is slow. But I am using this plane for down low stuff anyway.

I think my extensions are 30cm. And my CG is around 12 to 13cm.

Nac I know you've been hit with a few Qs here, but do you know how much current your motor/prop combo is drawing?

My mate will be running the same motor and prop and we're just not sure if his 40a TGY Plush will be up to it..?

I did some bench tests and with the 12x6 it drew 41A and with the 13x4 it drew 39A. I am also running a 40A plush, no problems at all.

- As the fields that we fly at are not very smooth (and a few bad landings!), the landing gear has become a bit loose. The wood slot where the wire slots into has cracked a bit. So I just used some polyurethane glue in the slot and secured the gear permanently.

These are both very easy fixes and only take a few minutes to do.
Yep, the landing gear mount setup is not tough enough for me. I eventually broke it today after earlier having the landing gear come out of the slot during knife edge spins and get chopped a little by the propeller . I am strengthening the mount area by packing solid EPP behind the wood mount back about 6cm down the fuselage and I will permanently mount the landing gear in the slot after filling it with polyurethane glue.

I'll add some extra glue onto the canopy front wood tab as a precaution since nac's one came loose.

Nac and I got enough footage today for several videos. I did a lazy edit on the first video by taking uncut footage of an entire 5 minute flight and just adding some titles and music. I'm uploading it to Vimeo right now. I'll post a link once it's done.

I sent some footage to nac so he'll likely make a video from it and I still have about 5 minutes of footage that I will cut into a shorter video when I get the time. We figured that we should get some video so that we can eventually post some evidence to support the bold claims we're making about this fantastic plane .

EDIT: here's the first video; 5 minutes of continuous flying from takeoff to a very interesting landing .

Nac, I notice you aren't using the SFG's. Have you flown it with them and can you tell any difference in flight? I agree on the videos, great job guys. Unedited vids are great, shows the planes true potential IMO.

Wow, I am impressed guy's, both with the flying and the plane. Can definitely see the difference with the sfg's, I would definitely put them on. I have some 25c 1800mah packs just looking for a home and you definitely have me thinking hard about this one. Can you tell me how many amps this is pulling with your setup so I can tell if these batts will handle the load? It is a sweet looking plane, have you tried it in much wind yet? I kind of need a windy day flyer, the other plane I have my eye on is good in the wind and flies awsome, but I like the full fuse on this one and it seems to carry a good bit of inertia so it tumbles pretty good. This plane looks like it really does fly very close to what a balsa feels like, is this your feeling about it as well? In the video it looks like it flies close to what my VR-1 flies like.

I was just going to order one of these but I ran into sticker shock. Between the cost of the plane+shipping, servos, motor, a few batteries, etc. it's closing in on $300 and I've been debating getting the eflite Cabon-Z YAK which is $299, decisions, decisions.....

My last order for a friend yak 54 + all eletronic from HK came in just over $200, not thing fanny but works well.Buddy of mine have one Eflite Cabon-Z YAK it bigger chunkier,fastter,harder to fly, and it not as fun as those Skywing EPP, I can fly mine low slow down to the ground do more stuffs you won't do with other, it just a fun plane to fly no worry.just my opinion.
cheer.
Note:Nac and Groove, allways entertening to wacth your guys flying. Thankz.

Thanks again for the comments....

I tried the plane both with and without SFG's. It is a little more stable in harrier with them but more challenging without them.
Hard to tell but the roll rate may be a tad slower with them on.
I suggest try them out, if you decide to leave them on then use longer screws and a little glue to keep them on.

I think the 25c 1800mah packs should be fine current wise, I am using 20C 2200's and getting 6min flights easily.
Flight time might be a little shorter perhaps but then the plane will be a bit lighter.
