Is yours the 6s or 8? Second flight looked much smoother great landings

Thanks. It's 6s. Here is this morning's flight after some control surface tweaks. I'm using 2x optical zoom on my phone hat cam to keep it from looking like a dot in the distance.

Morning flight. Wing lights are less effective than the F9F due to being flush with the wing. I learned it the hard way with the flight just before this one, almost losing control for lack of sunlight.
By the way I reinstalled the original Skywalker 120a ESC and it gave no hiccups. Great ESC. I was doubtful since it only gave three beeps when battery plugged in but seeing other YouTube videos showing the jet giving 3 beeps and giving a thorough ground test I decided to give it a try and was not disappointed.

[QUOTE=urrl;n410563]Maiden flight using Avian 130a ESC did not go too well, thrust kept fluctuating. Not sure if I can program it out. Hopefully that new ESC from Motion will arrive soon.

Hello

Just to know, did you do ESC/throttle calibration conform manual???
ESC/Radio Calibration
1.
Begin with the transmitter powered on at full throttle.
2.
Connect a battery to the ESC. The motor will emit a series of three ascending tones.
3.
The motor will emit two short tones to indicate the high throttle position has been accepted.
4.
Move the throttle stick to the low position within five seconds after the two short tones.

Nice landings and save. Still sounds like the ESC has still not detected the correct number of cells and it is going into low voltage pulsing too early. Assume you're still not getting the correct number of beeps on initialization. Did you ever try doing a simulated flight on the bench with a fully charged pack to see where the thrust fluctuation starts? Since I use only HiV packs, I had to do that with every aircraft before flying to ensure I wouldn't be facing an incorrect low voltage pulsing. Definitely gave me a little more confidence on any initial flight.

JP brakes installed. My version of JP brakes was wired directly int ESC wiring, not needing a second battery.

Braucht man denn wirklich noch Bremsen, ich komme sehr gut mit dem Rückwärtsschub klar.... sehe nicht, warum ich noch schwere Bremsen einbauen sollte?

Wow that's cool 😎

Anyone getting 3 beeps instead of 6 when plugging in 6S battery?

I watched mach3RC video on youtube on grass ops, didnt look like a lot of runway needed on grass?

Wenn du genau hinsiehst, braucht sein Jet elend lange bis er endlich abhebt, auf Asphalt braucht er grob geschätzt knapp halb so lange. Es ist und bleibt ein extrem grosser Unterschied bei Jets mit kleinen (Massstabgetreuen) Rädern, da der Wiederstand ein vielfaches höher ist als auf Asphalt. Ebenfalls ist das Risiko, die Nase bei der Landung zu brechen viel grösser auf Gras.

The springs in the struts are weak. Both the mains and the nose strut. On pavement it's no problem but on bumpy grass it will allow plane to tilt and the nose to hit.

What do you mean with firma up the gear?
like dubro wheels or?

My flights went well yesterday. The balance is very nose heavy and right now I'm 30mm behind the wing marks and feel it'll need to go back further. It does fly well, it is heavy and not agile. I have the 8S with 880g of battery and I think the 6S wouldn't be as fun. Flaperons and tailerons help. The airbrake does slow it down a bit and makes the plane pitch down a little.

If you fly off grass you will want to firm up the gear, they are springy and you will catch the nose pitot in the grass.

I am not a fan of allen screws at all. Why not keep it simple? Phillips head screws. I don't get it. What am I missing?

One thing is a certainty.. u need the exact allen screw.. not the case with a phillips head close will get it done.. i am with u aros

Interesting no one else has posted they got one or their impressions....

Mine is ready for the maiden. I said before that the battery area was good... Not so fast Evan. there is good room fore and aft and my 640g 6S and 250g 2S placed about 1 1/4" forward of the rear most possible location gives me a balance just aft of the book mark. Room to move aft as I expect it will need, or even forward. My batteries are 52mm and20mm wide and the battery area is just right for that but no extra room. They 42mm tall, 45mm where the battery leads are. If you are 6S and have the leads towards the back there is plenty of room under the canopy. If you are 8S and have the leads going forward then looping back with a series connector you'll have a clearance problem under the canopy. I use T connectors which are very small compared to XT or EC5 or other connectors and I had to dremel some foam and have to be very careful where the wires go across the top (no room to the sides) of the batteries. There is no room with the 8S batteries being placed more rearward for balance to have the battery leads and series connector facing aft.

And I haven't said it but this is a very heavy plane.

Ich bin auf deinen Erstflug gespannt, meine werde ich wohl im Oktober bekommen und dann vielleicht noch dieses Jahr oder sicher im Frühling einfliegen. Ich freue mich wie ein Kind darauf und auch auf deine Berichte und Feedback hier.

I absolutely like the Allen’s, much easier, more secure between the driver and screw head.

Seems to take off fast in the videos that are going around.

i refer to grass runways because we dont have pavement/cement runway. They put a big piece of hockey field artifisual grass on top of the normal grass. So there is no drag BUT as you can imagine its bumpy and about 70 to 100 meters long
