Official Freewing 90mm F-16 V2 EDF Jet Thread

[xviper]

Anyone have an issue with freewing 120A Brushless ESC with 7A UBEC and Thrust Reversing on the 90mm 8S v2 f16? Each time I’ve hooked it up it works great, once, then stays on reverse. Any help is much appreciated!

No problems here. Reverse works each and every time. Hard to help when we don't know how you've got it set up. What radio? What channel are you using for reverse? Do you have the proper switch assigned to that channel? Which switch? What are the limits of the switch travel (-100 to +100 for Spektrum)? Does that switch work for anything else? Is the throttle calibrated?

Great video Dr Tom! Sounds and looks much more realistic with the slower frame rates. I need to try that.

SWEEEET! Nothing like a secret night sortie! You land better with no light than I do in bright sunlight!!

Bummer! Glad it's repairable though!

Yes spring in the air but bloo,,, windy front gear appears my only problem more investigaitoin req.. outside that my sunday arvo and watching bathurst,, ( our daytona,,, ) has fixed most, already,, b safe

Very unfortunate! Been there, done that. We also have the scourge of grass at the edge of the runway, compounded by gopher mounds. We have a saying, "The runway never seem to be wide enough". No consolation but it could have been much worse. I'm sure you'll get her back in the air soon.
We got our first snow fall today. Our flying season is coming to an end for these sorts of planes. Lots of time for us to do repairs. Out come the float planes and VTOLs and "skidders". Melbourne must be well into spring by now.

Hey team hope you r all well,, so my remaiden on 1100 grams of 8s overall went well... almost.. first flight very good... i think its underpowered on 6s.. not so on 8.. but second flight slowed a bit much aproaching final ,almost hit the dirt... went around ,, good plan stan,,, buuutt.. just touched the long grass,, very long .. on the edge of the runway,, and flipped it.. overall minimal damage,, vertigal 1 outer pylon nose cone all easy glue fix... front gear ripped out the front bearing mount.. oh and 1 bent elevator shaft.. coulda been waaaay worse... generally easy fix,,,,,, couple pics bent shaft

Thank you very much for your detailed answer. I haven't had any particularly hard landings, but we have a very uneven grass runway, and the Falcon has a very long takeoff roll. Once, it folded over before takeoff while accelerating, and again after landing on the landing run. I noticed a grinding sound during retraction, and it turned out that the cutout in the fuselage for the landing gear leg was too shallow. I cut a recess there. I tightened the bolts on the pin, but the rod is already limp, and something is skipping in the retraction mechanism itself. I ordered a new one and will adjust it properly. The season is over here in Poland, so I'll be flying in the spring. Best regards.

Repeated take off and landing rolls on bumpy ground creates a vibration that will loosen the "driving" rod hex screws, or twist that rod or round the flat a bit. Look at the lower portion of your first picture (at the 2 grub screws). It's the rod that those screws clamp onto that is the part in question.
Also, the elbow of that articulated strut should be at least straight or even better, slightly over driven to lock in firmly. When you get the new part, operate the nose assembly and see where the elbow ends up. I think it's entirely possible that your current one came with that elbow not locked in, making it more easy to loosen everything and prevent a properly locked arm.
On my old one, when I took out that rod, it was severely twisted plus, the grub screws started to round off the flat. I put it in a vise and untwisted it and refreshed the flat.

Yes, this usually happens after one or two hard bumps on landing, such as hitting a divot or hump on the runway, especially if the driving shaft was not adequately "clocked" onto the first driven articulated arm. Hard to explain but if you take the nose gear out, you can better understand what I'm getting at. On the retract itself, look for the part that turns the articulated arm that connects to the strut itself. Either the hex screw(s) have come loose or the hex screws have gotten a bit loose from the "flat" of the rotating part. Also, the rod with the flat could also have twisted. When you take the nose retract out and run it using a servo tester, you'll see more clearly how the whole mechanism works.
You can then determine which aspect of the assembly is at fault ................. either undo the hex and re-tighten it with some FoamTac or Loctite or hone the flat back to the angle it needs to be or un twist the rod. The easiest and more expensive solution is to buy a new retract and arm assembly.

Has anyone had a problem with the front landing gear not locking?
