The wing planform is very simple. The CG could be worked out in a flash using the online CG finder and 30% MAC.

I'm still not feeling the pushrod exits at the most fragile part of the boom.I hope someone posts some detailed pics soon.

the wings do look Jart LT-ish, as said above:

initial reports indicated the model would be made in a composite way, but it does look like a JART-LT wing on a new fuse.
Each to his own but it doesn't look great to me.

I bet you can tape the wings on, mouldie style.

Other than that, you could put in "rare earth" magnets or multiplex wing locks.

Hey all,
Just picked mine up from Skip Miller today, before heading out to get in some climbing. That said, I haven't had a ton of time to dig into the kit. I'm sure Cody can fill everyone in much better, but for what it's worth here's some general info from the hour or so that I spent looking it over after I got home. Although I have been only sloping/flying for a year, I have built a Speedo 1.2 and it is one of my faves.

1) First impression. Cody had the plane set up for pics when I walked in the shop and I have to say I was pretty impressed with how it looked. The build quality for the price is pretty great. The plane, particularly the fuse, looks very impressive. The pics on R2's site don't really do it justice. The covering and on the wings and tail look dialed as well.

2) Inside the fuse - Having built a 1.2 Speedo, the pre installed servo trays and ample space on the new Speedo are a blessing, considering the tight build of the 1.2.

3) Wing joiners - The wings attach via one solid (not a tube) main wing spar. Additionally, there are two smaller carbon guide spars (approx 2"-3") that coordinate with holes on both wings on the leading and trailing edge. The main function here I assume is to prevent the wings from rolling forward or backward.

4) Wing Joiners II - It has two eye screws with a separate spring with hooks on both ends. Both wings have pre marked holes for these screws. My first impression is that the spring hooks to the eye screws and this pulls the wings together. However, when I asked Cody how this was supposed to work he wasn't sure as there is no real way to get the spring stretched across the fuse and hooked to the other wing. I have seen this system used in other planes, but those planes allowed you access through the top of the fuse to pull the spring across and hook to the eye screws. I did screw one eye bolt into one wing, put the wing by the fuse and then fished the other eye screw out of the other side of the fuse with some wire. From here I screwed it into the other wing (which was difficult) and when I let go there was still a good 1/4-1/2" of play. So that said, I have no clue how these would be functional... Maybe I didn't screw the eye screws in enough?

5) Wings III - With the three spar system, these wings will in no way break away like the original Speedo. I have had a handful of unfortunate landings out here in CO with my 1.2 Speedo and each time the tape split on cue, the wings parted and damage was minimal if not non-existent. This doesn't appear to be the case here. However, the wing joint/connection seems to be way more solid on the new version. The only thing I can think that would prevent the wings from getting damaged on a rough landing would be to remove the center main spar altogether, get the spring/eye screw system screwed down so it pulls the wings tightly to the fuse, then use the two 2-3" guide spars on the leading and trailing edge and then tape each wing seam at the join. The springs would then act as a shock absorber of sorts (if they didn't rip out of their anchors). However, seeing as the guide spars go into each wing no more than an inch, I cant imagine this would be stable enough of a set up... So I guess the key is no rough/cartwheel landings.

6) Exit holes for the elevator rods - Dual elevator pushrods, forked at the end of the pushrod. I'm guessing this gives more, precision, control and less flexing of the rods. Additionally, they include two stiff tubes, maybe two inches long, that I assume can be glued in to the exit holes to further reduce any flexing issues.

7) Colors- Ronald McDonald??? Seeing as this is a Chinese product, I'm guessing the colors could be more of an homage to the Chinese flag perhaps???

8) Random red strip of velcro - No adhesive on either side. Not sure what this is for....

9) COG - Cody had mentioned something along the lines of 25-30% of the wing cord... root cord??? Not exactly sure.

10) Overall impression - A solid deal for the price. In my opinion from an aesthetic standpoint this plane is pretty sharp looking, regardless of the "happy meal" undertones. With it's larger wing span if it flies anywhere near as nice as the original Speedo I'm sure this plane will be a crowd pleaser.

Saturday and Sunday look like they will be great days for sloping here in Boulder and I can't wait to get this built. Had I not gone climbing today I could have knocked out this build pretty quickly, much quicker than the original. That said, I'm hoping to hear back from Cody at Skip Miller or R2 to get some beta on the build a few of the questions answered so I can have this thing dialed in for the maiden.

Hopefully this helps a bit.

I got mine from Skip Miller yesterday. Well-packed and undamaged. The fuse is very light and sleek. The covering is flawless. Complete set of hardware including servo extensions. It looks great with the wings and stab on. If it flies as well as the Speedo 1.2 or the JartLT it will be awesome.

The only miss I think is the tail design. Way more complex than needed. The elevator is split to accommodate the rudder which is small and only extends about 1/2" below the elevator anyway. I can see splitting the elevator for a scale plane, but not if you don't have to. A copy of the Speedo with one pushrod out the fuse end for the elevator would have been better. The new one has 3 pushrods and 3 large holes in the sides of the fuse right before the fin.

I'm thinking of putting on a full elevator and either shortening the rudder or flying without. If I build it stock, I may try to fill the fuse at the cutouts with foam to strengthen it.

One last issue: the cutout for the stab is about 1/16" too wide so it will have to be shimmed. You could choose to go up or down a couple of degrees if you wanted.

I agree on the elevator set up. I scratched my head about this for a bit as it does seem unnecessarily complicated.

One option for the elevator that was mentioned by one of the guys at Skip's shop was that you could possibly set up the elevator to mirror the ailerons to some degree, like a V Tail configuration I assume...This could add to the aerobatic capabilities and tightness of rolls. Not excatly sure how you would do this, I'm guessing some type of mix function. It would require another servo and two seperate elevator push rods (as opposed to the stock forked one), but if the rudder is really not needed, then the rudder servo could be used in lieu of adding another.

Regarding the 1/16" gap in the cutout for the stab, while I used 5 min epoxy on my 1.2 Speedo for this, I decided to use white Gorilla Glue to take advantage of its expanding properties. This seemed to do the trick as it filled the gap nicely, not to mention matched the fuse color.

DylanCoffin, did you use the clear spacers that go between the aileron servo covers and the wing? Although I wasn't sure if they were necessary, I decided to use them. I may end up replacing the covers and taking them off.

Other than that, it was a pretty easy build. All that's left is to dial in the COG and get the throws set. Unfortunately it'll have to wait until I get home from a work trip this week. However, I should have some maiden info on Friday as Boulder is calling for some wind.

Cheers!

I received mine two days ago and it all looks good so far. I haven't started the build yet but will do so in the next day or two. Concerning the elevators and rudder, obviously you could go without the rudder but why the heck would you? Thats what will add a whole new dimension to this baby. Give me the Rudda Budda

Are you guys planning on just taping the wings to the fuse?
I think that will be fine.
Thoughts?
