It flies very well, smooth, quick…

Great color to lose sight of in the sky. Stupid choice. I'll pass. Change color to something more visible or offer the jet plain white and I will choose to color it myself. Then I'll buy it.

Why not just repaint it yourself? It takes a rattle can and a couple hours. I've done this myself dozens of times over the years.

Hello
Had 7 flights today. Very fast and quiet on 8 cell
Seems to have an issue with the nose gear being too short sitting at a negative angle on ground. ( leading edge lower than trailing edge).
i am running a cg about 1/4 inch behind recommend. Hard to keep it straight at takeoff speed. Seems to be pushing the nose down on runway
Anybody else have this issue?

The Vulcan and the Avanti V2 also sit at a negative AOA on the deck. This is deliberate and according to FW aids landing . Regarding take off handling, the first official vids show it a little skittish too, at least on grass. Likely, in my opinion caused by trailing mains on bumpy surface. It could also be a loose strut, they always come loose after a few taxis from new if you don't remove, threadlock and refit at the build.
A negative AOA will also prevent a premature rotation on bumpy ground. This is a similar shape to the Vulcan and that can flip just after take off if it jumps up and you have too much elevator use. Weird, as it's difficult to make it stall in any other flight condition. Go slow and lift the nose, it simply drops straight. Go faster and exceed critical AOA and it wants to snap. Guessing here, but I expect this to be a similar beast.

Thanks Evan, that clarifies the big picture and is exactly what I was looking for. When I'm finally able to get mine maidened, even though it’ll have an AS3X rx, I’ll always fly it without a gyro putting it through it's entire flight envelope: stalls clean and in landing config with all flap settings, upright and inverted snaps, spins, etc. only after that will I use the gyro for stabilization and compare the two.

Have fun tomorrow night with your Mamba 60!

It was slightly less stable. I don’t run gyros in my planes and a gyro would probably help. Most planes become pitch sensitive and I didn’t feel this did.

Rolls were nice. My high rate was higher than book and I was very happy with the roll rate. It does snaps and tumbles well too. I really have zero complaints about how it flies except the wing drop with flaps and flying slow. But I did have more flaps than the book number. After reducing the throw it was more stable but also didn’t slow well, but that’s to be expected.

More flights tomorrow plus since it’ll get dark early I’m taking my night Mamba 60 out :)

[deadbug]

Evan—thanks for all the maiden feedback. Just curious what, if any, change in flight characteristics did you notice as you moved the CG further back from your maiden flt (at +5mm) to the tail-sit position? For example, was it more unstable, prone to snap, or anything else noteworthy? Thanks.

[Evan D]

Show me a sport jet that doesn’t… If it bothers you don’t buy it.

Whats up with the name stickered all over the plane? Is this NASCAR now? Great paint scheme, terribe they put the name of the plane everywhere. Looks like a toy or advertisement.

[Evan D]

I notice the low nose but no bad effects from it and no steering issues.

Maiden plus a few done. Flies very smooth, quick, quiet. I ended up with the balance as far back as possible where the tail would just set on the ground and feel it could have gone further back. Careful with flap throw. Too much, too slow and it will drop a wing. This is not a walking speed landing plane. I think the flaps may be blanking out the elevators. But bottom line is it’s great in the air. Also bottom line, the Avanti is still king of the sport jets. My opinion.

[Evan D]

Sorry I don’t do video.

[MetallDanny]

Maiden tomorrow.

Woohoooo

You gonna record the maiden??
I order mine 6s today but no flying possible here in NL. To much wind and rain !!!

[Evan D]

Got it while I was at Hooters for lunch, well, it was delivered while I was there

Took about an hour to unpack and assemble. I think this was the simplest and fastest assembly I've ever done except for an out of the box UMX. The most time, still not much, was to cut off the EC5 and solder on my own with an anti-spark.

I bypassed the MCBe for the elevator, rudder and steering (on it's own channel).

The likes:
The blue is a lot darker than the pictures show, I know some still will not like it.
No glue needed. I did put some glue on the carbon tube pointy end things and I dis put some cA glue in the holes where the battery tray is screwed down.
I like that all of the screw were the same and hex.
The wing latches are awesome, even better than the B-25 and Cougar and the wing side is nice thick metal tabs, very well done, very positive and not easy to accidentally unlatch.
The motor (8S version) has the two tapped holes for the afterburner, which I did put on
Huge battery bay and my 6+2 5200 is slightly forward of the center of the battery tray for a 5mm behind the marks balance.
The spar and nose cone can be put in the battery area when not in use (I really wish all planes could do this).
Since everything screwed together this can go back in it's original box if needed in the future.


Dislikes:
The fuselage sides are very thin, seems delicate.
The lip around the canopy opening will get hanger rash.


Maiden tomorrow.

We all see different colors better than others. I can see blue and white planes better than any other combo. But I understand others may not.

Same here, ive never had an issue with blue and white. Grey, sometimes. But most of the time not too much of an issue.
