Maidened my Stinger 90mm today. VERY stable. I'm using an AR636 receiver mounted sideways on the side of the battery bay near the rear. Even in low rates (60%) I found the roll too aggressive on the first flight. I dropped the linkage for the ailerons one hole at the servo (Thanks RC Informer) and turned my low rates down to 40%) to calm her down. She lands super fine although on my second flight I managed to set her down too close to the weeds near the curb, spun and snapped the front strut connecting pin. Dammit. My bad for sure! But as a bonus, I found that the strut connecting pin is the same one used in the FW T-33, which I have several! Prior to today, the FW T-bird was my fav but now that I've flown the Stinger that may change. In two flights it's definitely grown on me!

Official Freewing 90mm EDF Stinger 90 Thread

Is this thread just about dead? And just why James is this "Official" thread in Military Jets and not in Sport Jets!
Anyway, I really like my Stinger 90, flies just as well as the Avanti, but too bad it's kind of looking and having to connect/disconnent 6 servo wires each time out was a pain, so it really needs to be upgraded with a ribbon cable. I wired each side into a 5 pin latching polarized connection so it goes together and comes apart in seconds, with very little stress put on the servo connectors.
Anyway, I spent the last several months upgrading all of my 90mm EDF's to the 12 blade inrunner, with the exception of the Stinger 90. Mine had the old 12 blade 1650 Kv outrunner in it, yet it still flew very well. I wasn't about to spend $100-$160 upgrading the fan for that one, but earlier this month got a 2nd Hornet that came with the 9 blade inrunner. I also bought the 12 blade for that one, so in essence the 9 blade only cost me $20 if I would have got an ARF and the 12 blade fan separate. For that cost, I was more than happy to upgrade the Stinger. Bottom Line, it was well worth it! Flies great now. It's nice to see MRC upgraded the Stinger with the 9 blade (wonder how they're selling though at the new price), but if you still have the old 1650 Kv outrunner, you may want to upgrade it to the 1900Kv inrunner. Oh yah, and definitely rewire the wing connections and maybe do some cool repaint. I'm flying mine on a RT 6250 and get almost 5 minutes of flight time, not too shabby for an "old" EDF.

Anybody else having trouble with the nose gear pin breaking? I just attempted my 3r maiden flight and on all three take off rolls The nose gear pin breaks. Finally got a video of the third fail. After the first maiden and nose gear collapse I tried make a warranty claim and was told to provide a bunch if information. So I provided it all the them and was then told that since I didn't get a video of the event they couldn't help me. I sent a nice email just saying "thank you, I appreciate your help". I got no reply, but within minutes I got an email saying the new pin was ordered. Weird, but they did send me the $4 Pin, of course after I ordered one because I thought I was S.O.L..

I will try the vice/hammer experiment with the remaining section of pin. It fractures right at the edge of the ground flat spot for the grub screw on the steering collar. Very little if any bending. My experience with gear pins is the same as yours, they should be soft enough to bend. This picture is of the original pin.
I had full up elevator on that take off roll in the video too. I own the Venom and Mig29, another guy flies his Avanti, Me262 and F104 (all Freewing) off this field with no problems. I also have an EFlite 70mm F16 that everybody warns me about the nose gear collapsing and it hasn't after much abuse.

Hugh, he’s posted on here and RCG. His first post was saying major design problem which it is not. It’s a quality problem either the pin.
you pointed out the F-4 and there were a few that had that pin break (I wouldn’t say many) and I replaced mine with a different one, I think for the F-14, it’s been a long time.
Anyway he needs to let Motion know there’s an issue (not just ask for replacements) and then maybe look for alternative pins or a retract with a larger diameter pin like the MiG 29. But the there’s the issue of if that unit will fit the plastic mount.

This is a pic of the broken pin next to a pin from my Sebart mini avanti. As you can see there is absolutely no bending. The Sebart pin did bend like it should, because it was designed and built with the correct hardness. The Freewing pin was designed and manufactured out of metal far to brittle. That's what I meant when I said it's a design problem.
I guess I will contact Alpha, but I'm sceptical after buying a Mig29 at the first pre order and having one of the first nose dive experiences early on and nobody believing me. I was called inexperienced and a bad pilot until it happened to others. Kinda got the same vibe when I made the warranty claim on the pin.

The yellow looks so much better! I am going to have a stronger pin made, but I may also see If I can find a different front retract with a larger pin like the Mig 29. Or find 2 larger diameter wheels for the stock strut. My Freewing Venom has no problem with this runway. Why they aren't smart enough to put larger diameter wheels on a sport jet I don't know. It's not like it has to be scale looking. The Freewing Avanti glides right over this field. A good rule of thumb would be to avoid using a small pin with small wheels on the nose gear. I bet you could put a lot of weight over the Avanti nose wheel and run it up and down this runway without a problem.
ALPHA, JAMES IF YOUR READING THIS HELP ME PLEASE!! Probably just a cry for help in the dark.

I got the pin made and installed it today. In doing so I noticed the left main gear wasn't fully retracting. The strut was stuck in the full up position, with the spring fully compressed. I had to work at it to get it extended. I thought oil would help, but it didn't. Keep in mind the plane came out of the box with either two left struts or two right struts I can't remember. I sent a message to Motion RC about it, see what happens. This plane is getting expensive and it's still not right.
