Official Freewing 80mm Avanti S Sport Jet Thread

[CFIT rob]

My 1st round preorder avanti was flawless except for the ground avoidance system.....that still needs improvement. (Lost orientation doing some wicked looking lemshevocs, got into a spin and four mistakes later...heartbreak and foam bits). Had flaps on 3sec delay and using control board no problems in 30 ish flights. Avanti #2 .... 6 flights same programming, two landing flap no retract episodes. Left servo both times. Will change to 1 sec and give follow up.

I bought a nice used Avanit that has a few wing tip rash marks. The LED lens is also scraped up. I see they have a replacement lens. How hard is it to remove the lens on the wing tip?
Thanks...

+1. I had a 3 second deployment for flaps programmed on my transmitter and encountered similar issues. I changed it to a 1 second deployment + reseated the servo plugs in the wing root boards on both sides. Have not had an issue since.

I had the flap deployment speed set at 1 second and I confirmed that the servo plugs are firmly seated. It looks like I need to bypass the board and plug all servos directly into the receiver.

Try one last thing before you go through the PIA process of running new servo extensions (you may have already done this). When I took off the wing root boards, I cycled each flap and aileron servo separately using a cheap servo exerciser. If you don't have one, I'm sure you know you can hook them up to a spare receiver to test them as well. If servos are working as expected, then it's probably time to run extensions and bypass the board as you said.

In reference to the flap issue, I wrote about mine before. I was having an intermittent problem with one flap no going all the way up after landing. If you touched it, it went up all the way. After reading some of the earliest post about a possible control board problem,( I got mine in the first batch), I went ahead and pulled it and used extensions since I don't remove my wings. The only problem is that you have to get a LED controller to run the lights. Obviously the board has a circuit on it for the strobes and to reduce voltage to the lights. I then flew the Avanti for a bunch of flights but was still having the problem. I figured it only happens after I land so why bother. We all know that the magic repair fairy will come in the middle in the night and fix it. Well, I went to drop the flaps and the jet went into a crazy roll. I pulled the flaps up and back to level flight. Lined up again and dropped them again, same result. Landed with no flaps which I don't want to do again. It rolled a long way into the high grass. Bottom line is I replaced both flap servos and the problem has not come back for over 30 flights as of now. Luckily I had some Freewing servos with 550mm extensions which fit perfectly and eliminated an extension to each. I have had a flap servo go bad on my Yak 130 before and after replacement had no problem. Still love this jet and it seems to never come out of my truck so it's always ready to fly.

I forgot to add that I tried changing my servo speed also and if I went to the 20 setting, on my Futaba, they didn't work as well. I have them set at 15 now.

I've experienced the non retracting flaps as well like rosytime said, normally at the very end of the flight, I went to move the flap manually and it had no power to the servo so I could move it freely. After cycling the power the flaps started working again, maybe the landing jolt upsets the control board in some way.
it's annoying but now I only ever use the flaps for landing and go straight to fully deploy and they can stay there until I fly again.

[Grossman56]

Guess I've been lucky so far with the flaps, nothing unusual so far. I've found that she doesn't need take off flaps and so I've only been using them for landings which is fully deployed. Hopefully Alpha has been following this discussion and is looking into it.

I followed your recommendation and checked the wing servos with a servo tester and they all operated normally. I will try connecting the ailerons, flaps & gear direct to the receiver and try to keep the lights connected through the control board. We'll see if this works.

I tried to do a work around to still use the board for the lights, but as you will see, it can't be done because you have to use the ribbon connector. You'll run out of room in the wing openings to run the extensions and the ribbon connector unless you want to modify the opening. I chose not to.

I am running a 1 second delay also. No problems in 40 plus flights.

FWIW I just went and checked my blog (where I keep count) and have 84 flights on mine. These have all been with the board and running a 2 second speed on flap deployment. .

[CAPT John]

I ran extensions and Y leads to the ailerons and flaps and connected them directly to the receiver. I left the landing gear and lights plugged into the board and all seems to work well. I don't remove the wings for transport so this should be a reasonable work around. I look forward to getting her back in the air this weekend.

Just pry the lens off, they are glued on.
I put new lens on mine also.

I figured as much but wanted to make sure.
Got my parts yesterday and my plane today.
Can't wait to get it into the air!

how did you glue the foam to the canopy ? which glue did you used ?

Welcome to Hobby Squawk Pascandrea. This is what I have found to be good for the job.

[Grossman56]

Or Foam-Tac as well, that's what I used, worked great!
Welcome to the Forum!!

The little white tube of contact rubber cement that comes with most PNP kits also does well on canopies. :Cool:
