Official Freewing MiG-29 Fulcrum Twin 80mm Thread

What the heck crashed my MiG-29 on final approach today jet headed straight nose down and was totally destroyed. After investigation noticed that one of the elevators detached itself from its mounting plastic bracket very little glue was used. This is unacceptable from free wing.

Glue is expensive, apparently. Canard detached from my Rafale yesterday. Fortunately no crash ensued.

Just finished my Red Star version, this has me concerned. Mine seem super solid. I will definitely include this check on my pre-flights. After seeing this I was considering laying some fiberglass overlapping that area, but like I said, mine seem real solid. Sorry to see this happen to you, that's about the worst way to lose a good plane.

You didn't happen to have any impacts on the tail before this event? Anything you think you might have missed, or just a case of bad quality control on this particular bird?

[Evan D]

Yes, two of these.

Want to put the Freewing Tail Flame afterburner in the Mig 29.The dual Tailfame afterburn is no good because it has 2 separate motors .So I was thinking of buying 2 single separate Tailflame afterburner and installing them on each motor .Will that work ?

Unless they've changed it recently the Tailflame controller turns on at a stupidly low throttle setting (like 15%). It looks silly to see a jet taxiing with afterburner on. If you do a search you'll find a thread somewhere that describes how to fix it.

But they are cheap.

Adhesives seem to be in short supply in China.

Today's the turn for the 'big sister'...

Sounds like you’re doing everything right…

I purchased the MiG power system (ESC’s, fans/motors) to install in my FW 80mm F-14. I have everything installed, but I cannot get the non BEC ESC to calibrate. It just does the single beep every second or so. The BEC ESC calibrated just fine and works great. I first did the calibration (throttle stick full) plugging both batteries in at the same time. The BEC ESC calibrated immediately, while the non BEC ESC just did the single beep. I then tried just powering the receiver with a receiver pack and plugging in only the non BEC ESC to the throttle channel. Same result, just one beep. I tried with trim all the way down and all the way up, nothing. I tried increasing the travel volume, no help. Lastly I plugged in the Skywalker 80a non BEC ESC that came stock in the plane and tried that. It calibrated immediately just as the 100a BEC ESC had. So at this point I am out of ideas and figure I got a dud ESC. Does anyone have any ideas what may be wrong?
Thanks in advance

Hey all,

Has anyone installed the new 12-Blade EDFs with the 2150kV motors?

If so, how does the new 12-blade compare to the proven but original "Fan-favorite" power system using the 1920kV 9-Blade OEM?

Thanks in advance.

Best, LB

A lot of people suspect a lot of things that are simply good. That said many do bypass several things that have no real need to go through the MCBe.



Setup by the manual with CG about 2cm aft of book is a good start. I really like tailerons on mine.

Over the years I've had more Y cables fail than blue boxes or MCBEs. All you do is replace one possible source of failure with another. Plus you add the possibilty of user error if the replacement involves programming your transmitter to duplicate a function of the box.

Seems that the MCB-E has been a suspect in several airframes besides the MIG-29, I would rather be safe than out a bunch of cash.

Thank you,
I bought the version with TV installed so that mod is out of the way already.

Good deal. Others will no doubt chime in, but set her up by the manual with CG being the exception (I don’t recall how much farther aft of mark).

She’s super easy to land. Enjoy!

Having lost a MiG due to high alpha lock, at the top of my list would be adding the vectored thrust kit. This mod pretty well makes that aerodynamic quirk go away. If you bought the version with the VT mod installed, you are ahead of the game.

Then follow the suggested guidelines on CG set-up.

Is there a list of the recommended mods or a post # that has all the important ones? 6K + posts to dig through looking for this info is taking forever

The MCE-B was a convenient scapegoat early on.

Funny how these MCB-E problems went away when stronger servos were installed, don't you think?
