Official Freewing MiG-29 Fulcrum Twin 80mm Thread

[GliderGuy]

My opinion is if you have TV you should be okay with that balance, maybe even a bit further aft, and set up. If not I'd recommend no more than 10mm behind the marks. Rudders are no issue. I would recommend the reflex at some point, it made a big difference in the horizontal stab neutral position.

Good luck with the maiden.

And….even more specifically….if you don’t have TV, GET IT!

I eventually lost my MiG because I didn’t install TV. It is not a matter of “if” but “when”.

No TV and no plans to install TV? Then don’t fly on windy/gusty days and don’t fly when there are thermal gusts.

All it takes is a gust to throw you into high alpha lock close to the ground and she’ll eat dirt. Without TV, it takes altitude and chopping the throttle to recover from alpha lock.

I loved my MiG! She flew GREAT! Flew her several thousand times. However, she is now a pile of mangled foam that I dig through for spare parts.

Hi, going to maiden this as soon as the windy weather lets up. I have read a lot in this thread but not every post. Appreciate all the info here! This has the upgraded elevator servos, arms, rods, etc.. This is my 2nd EDF. Been flying the FW L-39. This is my first twin verticals plane and when checking the rudder throws, the left and right rudders don't match each other. Traveling right, the right rudder travels further than the left rudder. Opposite when traveling left. Since they are Y'd, just live with it? Was going to CG about 10mm aft of the mark, ailerons on a low rate(50% of high) to start, all else by book high rates. I'm using SMC 5300 HV's in the rear and center locations. Ferrite chokes on each ESC battery wire pairs. Relocated the UBEC to rear wing root pocket to empty front bay for an AR637T (its antenna's at 90 degrees to each other) with a SRXL2 remote all the way into the nose. Will do extensive range testing at the field. Debating about 1-2mm of reflex in the ailerons and flaps for the maiden. Anything else to consider?

Like in the movie "Chronicles of Riddick" ................. Judy Dench's character ................ "What is the odds of that?"

dbirds2 please self-edit OR self-delete your posts over the last 24 hours in the forums. Clearly, I do not need to explain why. Respectfully, LB

Hard to say but it looked like alpha lock followed by a helmet fire.

Don't feed the tr... the smack helo guy.

Dont worry I wont feed the tr.. the chickenstrip racebike guy

[dbirds2]

You guys still don't have him on IGNORE? Shouldn't quote him either. That way, nothing he posts will show. Eventually, the mods will see what he's doing and deal with it.

I was wondering from your post here about control. IM pretty sure I know your types. JUst look at the words here. I havent said anything to anyone. I have only voiced my displeasure with a few certain planes and you dont like it. Well tough........ dont read or respond but basically begging for moderators to shut someone down cause you dont like the content. Well that shows exactly the type of person you are. I can think of two words communism and fascism. Stuff dont fly in america....

[dbirds2]

Yeah...it clearly can't fly! As is shown in this video...

I put the 2200kv xfly motors in the bird yesterday took 4 flights today and actually performed quite well. Probably performed the best flat spin ive done or seen in a long time. To the trolls who I never asked for or jumped their posts dont like someone elses posts dont comment. its pretty simple

nothing would surprise me with this heavy foam anchor trying to ffly. Such a crappy jet and that is being nice.

A lot of interesting things happening. First they post a lot of videos and there is typically a high percentage of flying "issues" at that site. Many of the planes dis not look set up well, too much pitch or other axis authority. Then flying large and small EDFs and a bush plane together. At the end it looks like the person was in semi alpha lock.

If you remember, when the MiG first came out they lost a few. I said then it looked like they didn't know there were three places for batteries and used the forward and aft ones making their planes very nose heavy causing issues. This looks surprisingly similar to that but with TV to further mess with controlability.

Such a crappy jet and that is being nice. thrust vectoring imho has very little positive effects on this jet. doesn't have the thrust to really utilize the vectoring nozzles. THe videos Ive seen with the mig 29 trying to do t.v stunt, look to be doing same stuff, aerobatics where you start to do move but the jet just cant push enough power to complete so it just stalls out and goes nose down. Freewing should be ashamed to sell this jet with thrust vectoring.

Another MiG29 goes down. This time one of the new "Red Stars". What's with these guys? Even before the mid-air touch, it was a flying roller coaster. (I don't think the mid-air did any damage.) They don't seem to know how to set these things up or know how to balance them or they just don't know how to fly them. The MiG wasn't the only "roller coaster" out there. Many of them were going up and down like a yoyo.

[dbirds2]

I will cut ties with this mig 29 for 450 dollars. Im serious. text me if interested at 4255907303. Im in washington state if anyone local wants to buy.

I read something interesting: In the JETPower-magazine 1/2023 is an article from Philip Baum, in which he writes from his Skymaster F/A-18C Hornet. He observed the following: As he extented the flaps, the Hornet put her nose down and he had no control of the elevator anymore. He would have crashed if he did not retract the flaps and gained elevator control again.

After that he got in contact to others flying the Skymaster Hornet, also guys from USA. Some of them knew the problem and the solution seems to be:
(a) Use very strong servos for elevator, in this case up to 70kg at 7,4V
(b) Use premium cable for elevator servos (like the cable from Hacker or PowerboxSystems as discussed before in this thread)

I found this observation quite interesting because it seems to be similar to the observation on the MiG-29. Reading that I am glad that I set up the elevators of my MiG with MKS HBL550 servos (38kg at 8,2V) with premium cable from Hacker.
I installed them in that way that the pushrod is parallel to the fuselage. But now the pushrod touches the elevator when moving - ouch ;) I still have to solve that problem...

Although it's never a bad thing to have stronger components, especially with respect to elevator servos in this MiG29, "observations" should also be tempered with regard to other details. In this particular case, such as size of flaps and elevators, deployment speed of flaps and possibly other factors that have not immediately come to mind. Shortly after Freewing sent out stronger servos, I recorded a flight with a pylon cam to see the effects the flaps had when deployed 1/2 and full, at speed. My flap deployment speed was set at around 2 to 3 seconds, going full throttle and at max speed. No dive was experienced and elevator control remained. Aside from this experiment, IF the elevators were "blanked out" by the flaps, thus resulting in zero elevator effectiveness, what does it matter how super strong the elevator servos and/or how good the cabling were?

DOES MOTION RC not allow honest reviews for purchased products on their website.?.

So ive spent some time with this jet now and its not going to get better. I got 108mph out of it on a good day but with the sheer weight of this beast you need imho about 130mph plus to really have some fun with thrust vectoring. Ive added some reflex into the wings and it made a difference of about 4 mph on average. I dont have ay data to back this up but I think the thrust vector version is losing alot of thrust versus the non t.v version. On the other hand I added thrust vectoring to my f22 raptor and its on 10s. MY f22 will fly circles around the mig in every way and I got a 140 mph gps reading of it. THe f22 is exceptional, very aerobatic and very fast, keeps you on your toes. THe mig 29 I can just raise throttl stick to 100% for the entire flight grab a coffee and smoke and chill out while flying with my right stick. THrottle needs to be at 80 percent or better just to keep it airborne. If anyone is interested I am looking to trade this mig for a su35 in excellent condition or a gripen straight across for my mig 29. mig 29 is new with 15
