Notes; Plenty of battery room for the 6+2 5200 I use. Haven't got it fully assembled yet, still working on wiring but balance should be okay too. I should know later this evening (all done and no issue balancing it at the box spot and there's room to move them back to where I think the CG will end up being). The airbrakes go on with one screw and there are also two mounting posts and it seems flimsy. But they work really well on the bench. Can't stuff wires behind the MCBe as that's open air to the fan intake. I am bypassing the MCBe except for gear and lights and have it rotated 90deg and the receiver next to it. Very easy to bypass as it' s one aileron wire per side, one stab per side and the rudder and steering. I also have an Assan steering gyro in mine. Great quality and no quality issues to note yet except the ball links, they are heavier duty grey ones and don't have a strong snap onto the metal balls. I tried attaching them both directions and the side that has two small molding dots seems a bit stronger but not much. Another note is the screws, they are all allen head and some are machine and some sheet metal/ wood screw type. The only place they show using the non-machine type is for the stab pivot shafts into the fuselage. The ends of these are pointy and it seems a flat end would be better so I flattened the end with a dremel. Also there ended up being a lot of spare non-machine ones (they were for the wing tip rails) and no spares of the machine ones. They really need to review what they call them or have a big picture of each and also a list where they show the parts telling you where each screw goes. They only mod I think this need (bypassing isn't really a mod to me) is the stab shafts should have flat spots on them where you tighten down the set screws in the wheel collar type fixing rings. All the planes that have these wheel collar type retainers should have this.

Anyone tried grass field yet?

Ich nicht, das will ich auch nicht. Eine F-16 ist in diesen Größen einfach kein Jet für Graspisten... das ändert leider nie, weil eine F-16 immer zum Kippen neigt auf Gras... und dann ist jeweils die Nase weg.

[Evan D]

I feel this way about all jets. The issue is there are many that don't have access to a paved runway.

Eine A-10 oder eine Viper-Jet wäre da viel die bessere Wahl auf der Graspiste, die haben breite Fahrwerke, aber leider keine F-16, egal welche.

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.

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

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?

[Evan D]

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

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.

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.

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

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

[Reptielenfreak]

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

[Evan D]

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.

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.

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

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

Wow that's cool 😎
