Here's a short clip of my Mig29 a few weeks back. There's two take offs and a bit of flying footage but no landings. Ive manged to get three videos of takeoffs now but still no landings which is a shame because she lands so well.

Cheers

Very nice. What turbines are you using the speed looked very scale to me.

very nice

Levi Wags

Thanks guys.
John I'm running two P140RXs which I think is perfect. I'm at half power most of the flight and full power for takeoff and verticals.
Even after takeoff I throttle back before the first turn and It's got unlimited vertical.
Mines no lightweight either. With operating intakes, slats, flaps, speed brakes, animatronic pilot and all the options, she weighs 23.5kg dry.

cheers

Nice flying Levi.

Mine was was flown again today, just one flight before rain.

The model had one engine flameout at about 10 feet on takeoff. Whether this was due to a voltage drop on the Ecu battery which also feeds the hyd. pump, I don't know, but I will arrange a separate battery for the hyd. Pump. I will interrogate the JetCat Ecu tomorrow.

OK, engine out flying !

When the failure was seen, smoke from the engine, I throttled back somewhat and got the gear up.
I then maintained height with the model in a gentle but controlled turn in the direction of the failed engine and allowed the speed to build. Roll control stopped the moderate roll without using full deflection. ( Memories of flying the Canberra many years ago came to mind , but that needed a bootfull of rudder I had a real engine failure in the Canberra in exactly the same way.)

With a decent speed increase I added some power and climbed to a high downwind leg, and remembered at last to feed in opposite rudder.

With plenty of of height I dropped the gear and reduced power and flew a steep approach with minimal power. Landing was routine, only to find, again, a damaged nosewheel. steering cable. (How is yours rigged?)

Flaps 15 remained for the whole flight, no landing flap on finals to keep power to a minimum.

Anyway, the Mig WILL handle asymmetric flight and so long as power is kept down to a reasonable level commensurate with speed it is fully controllable and shows no nasty tendencies.

Thanks for the description. Do I read it right, you turn into the dead engine?

Craig B.

David,

here is a photo of mine. It is important to smooth the edges of the holes in the steering horn and the arms otherwise the sharp edges will cut through the cables very quickly. Made the bracket myself to bolt onto the strut. The steering arm really needs ball links on the top to avoid issues with the steering cable and the geometric rotation of the steering arm.

Levi Wags

Nice set up as usual Craig,

David that sounds like a great result from maybe the second worse thing that can happen on take off. The worst obviously being duel engine failure at the same point.
Just goes to show a calm experienced reaction works much better than panic.

I got rid of the cable set up and custom shaped a pushrod which I've never had trouble with. I'll see if I can take a pic.

Im glad you were the one to test the single engine flight and not me. Good to hear she behaved OK in that configuration.

PS David during the recent flights with my Mig in the video, two of my good mates and your old sparring partners were calling for me. Mr Bennet and Mr Sparkes. In fact that pair have called for every flight of the Mig thus far. I know they were both with you on the maiden flight of your Mig at Wangaratta in Australia many years ago too.

Cheers
Levi

Craig B.

Thanks Levi. I am not 100% satisfied with it yet though. Would like to see what you did on yours...please post a photo.

David Gladwin

Guys, thank you for your replies.
Mr Matt, turning towards the dead engine is to be avoided if possible. When the engine failed, it started to roll and turn left. As half roll input stopped the roll, I let it continue to turn gently, small bank angle, towards downwind so continued and accelerated to be well above safety speed. ( more speed, greater control authority). Then started to climb with more power added.

Craig and Levi, thanks for the info on nosewheel steering, I will take another look at mine based on your experience.Levi, please give my best regards to Sparkey and Paul, many happy memories of flying in Australia.

I hope my experience will give you Mig fliers even more confidence in the machine. We now know that it can take an engine failure at a critical time at max. weight and still fly to a safe landing.

David.

My Feedback: (1)

David, I'm guessing it was a left hand circuit that day and you didn't have much choice about turning into the dead engine?

David Gladwin

Exactly, Harry , if I had tried to turn right it would have taken the Mig towards the buildings instead of open airfield. D.

David Gladwin

Two more great flights on the Mig yesterday. The nosewheel steering problem is fixed. I ditched the cables and, like. Levi suggested, I used a heavy duty ball link and clevis with a single rod connection. Works fine.

However, preparing for a third flight, the gear check showed all was not well, gear was not retracting fully and doors not closing fully.

Inspection this morning shows slightly bent main leg struts, just enough to prevent proper retraction.

Thus us will be difficult to fix as replacing the struts with straight ones might just lead to a repetition.

I will ask our CARF rep if replacements are available and whether later legs were made stronger.

In in the meantime has anyone any suggestions ( or replacements for sale ! )

Both landings were normal, slight crosswind but otherwise fine.

David.

Levi Wags

Great stuff David. I bet it was good landing with two engines running this time.

Hoepfully someone chimes in with some struts. You would think there has to be at least 50 sets across the world sitting in boxes unused.
David from memory your Mig was an early one being FC? Mine being a little later may have stronger struts as I've had no problems with them thus far.

Joseph Frost

Hi Levi, I was recently trying to contact you, can you send me PM with your contact. Do you remember about 5 years back at EH? Is it still the same model? Real beaut. Are you coming to the air show on 1st and 2nd of next month? I'll be there doing some static demo with few jets as a sponsor. Might catch up after long time, Cheers, J.

Levi Wags

G'day Joseph. Yes that was a great day up north mate. Excellent venue.
No the Mig in the pic was my old Skymaster one. Great model. The new one is CARF and is bigger, more scale and twin turbine instead of single.
Yes I'll be at the air show doing a flying display with the F16. The Mig is too much of a headache to operate in a 10 min slot.
Ill look forward to catching up with you there. I'll send you a PM with my details.
Cheers
Levi

Good Day

Is there anyone that can help me out with a manual for this jet

Please mail it to [email protected]

Thanks

Can't help with a manual but here is a build thread I did on the mig. It might help. The manual is pretty useless anyway.

Hello everyone I am back and I decided to start on my Mig 29 that I got unfinished and with a lot of mistakes from the person that was building it. First I need to install the fuel tanks and then I will work around with the other. As you can see in the pictures I had to redo all the plumbing due to the fact that they were installed in the fuel tank position so now it looks more cleaner and I can install the tanks one I receive the clunks.
As I go through the whole airplane, I might need some help with certain things if you guys can be kind enough to give me some pointers I would appreciate it thank you Nick

Here is also the tanks right before I join them together . I am running two different pick ups for each engine separate and to vent lines on each tank for better flow I think it will work the best here is the position how they will sit inside the airplane

Hi David

I saw your recent article in RCJI. It would be marvellous if you could post a diagram of your final hydraulic setup here on RCJI or otherwise make it available to those us yet to tackle that part of the build. I know you bought the Omega system but think you have supplemented hat with Hausl valves and pump/accumulator? My email is [email protected].

Cheers
Paul

Hi David , I need the accumulator and the pump myself because when the person was installing that he busted the amplifier I try sodding it on the little PCBoard but I don't know if I did a good job on it I need to test the hydraulic system to see if it works .
As for the intakes I will just make them air through instead hydraulically I will post pictures in a different day I saw my Friends Russell he did it like that and they work perfectly as you're flying through the air they just flip back. One less headache .

Craig B.

Hi Paul,

I can't speak for David (he may well have done the same) but Levi and I have used the Hausl pump and pressure accumulator and that works well. I originally bought the Omega system and have an unused ECU if anyone particularly wants it but I subsequently bought the Hausl unit and am happy with how it functions. Here is a video of mine working.....

Levi and I have 2 cylinders on the nose gear....the original one in the scale position and also the newer version that fits the modified upper frame. Using both made for a very definite retraction and extension cycle but Levi can chime in with his experience also. The front of my mig looks like an ad for Festo!
