I agree with Craig, you need 10 bar , 150 psi. Mine does work well at that pressure. Make sure, though, you use the Festo high pressure tubing.

Make sure you retract the gear in straight flight before the speed builds up too much. Retraction during a turn has a G effect and will slow or prevent full retraction.

I will also add that I added a duplicate line on the pressure UP line as PH suggested volume is almost as important as pressure.

Yes Craig, 3000 psi would be great, but possibly slightly excessive !!!

hi George,
66.5 lbs. wet and I am running two 140 G kingtech , and I get good six minutes of flight.
How is your SU 35 ? I am going to paint mine this winter and put two P160s jetcats for power.

Hey Nick,Maiden the su35 with twin p100.. perfect combination . video in my thread here http://www.rcuniverse.com/forum/rc-j...minator-5.html

But my love is for the su37 vector-thrust version . With scale nozzles not the ugly-look vector systems we have.
The last year i made a spot welder and having loads of test flights. Problem is cooling...after flat spins and cobras in low speeds, rear fuselage gets too hot
I dont care if ill burn it to the ground , i want the su37 version or nothing
The last 5 months i came up with a design of a flexible secondary cooling wall and the problem disappeared .Like a standard double wall pipes but with the last part moving.
Im waiting a higher grade stainless steel to arrive to make the final design and keep on testing ...
Once i have news ill post them in my thread..

I am a long time jr user but the futaba servos seemed far superior. I have also heard that a 75 kg futaba is on its way. Would be a great option. My whole mig is now fitted out with Robbe futaba sbus setup and a mix of futaba 177s on the tail and 8911s in the wings, KST x10s on the rudders. Still finishing the final fitout but I am loving this thing! Major engineering exercise but if you live that sort of thing as I do then it is very rewarding as you know. Will check out your pics.
Hi

If you looking for some replacement BLS177SV servos's I have 12 brand new going cheap

Hi Hemi,
I sold it to Mark F. from CompARF when I moved to Germany. Nice guy.

You have to shim the main mounts to get the correct scale verticle alignment and adjust the scissors so the doors close all the way!
You can see my images early in this thread.

I think twin P100-130 would be perfect these days. Saves weight and less wear on your Migs. Don't use heavy cockpit kits either may help.

Hey Bob. You can google the specs or check CARF website. Mine is 23.5kg dry. Its on the heavy side for this Mig but I have everything operational. 2 x P140RXs. Its a dream

I have just spent a couple of days going over my Mig ready to fly this weekend, sadly now cancelled. due CV restrictions.

A few points:

A few rivets holding the jetpipe to the bellmouth were coming loose. Unlikely to fail completely but ........ ! Take a look guys.

The wheelbrakes on this model have always been poor. Has anyone redesigned the wheel/brake assembly?

The Festo pilot valve, recommended to me by Shane Harding , have proven 100 % effective. Model stood on its legs for 6 months, no sagging !

Hydraulic system now running at 12 bar, working perfectly.

My jet has now been tarted up, burnt nozzles, cockpit and pilot, IR detector etc but still a way to go To begin to match Levi’s superb effort.

Had a close look at real SU 27 in Moscow recently, god its ugly compared with the 29 of which a number are on public display there, all looking very tired and neglected. The SU looks like a Mig which has been on a starvation diet.

Really looking forward to flying the jet. again, twin JetCat 140s, Futaba servos,, HPS a700 s installed ( thanks for the tip Craig) perfect !

Hello friends
Well my kit is up on its gear...yea. However the person I got her from had misplaced the nose cone. Does anyone out there have a damaged bird they are not going to fix or a extra nose cone laying about that you can part with.
Thanks

Hey guys, how much interest would there be in a 1:5.5 Mig29 Arf? I am contemplating a super scale scratch build project...

Hello guys I have been flying mine and I can tell you that this is the best and easy jet that I have flown so far.
but if you wanna design And make a mold you should consider the SU 57 at a 1/6 scale .
just an idea and I know it will fly off the shelf.

1:4 would be better. The 29 is not a very large plane. You cab get a lot more detail with a large aircraft. Much like skymaster has done with the 1:4 SU30.

Default Finally ready for maiden!

20 years have gone by since kit #29 came into my possession. Still a few details are missing, but I am now ready for the maiden flight.
Wish me luck!

Good luck, Per

. Love that Ukrainian colour scheme !
This jet is a complete doddle to fly, just so docile even with an engine out !
Mine is waiting for spring, sat on its gear all winter with NO sagging!
Twin JetCat 140 s, Futaba HPS A 700 servos on Stab.
A delightful machine.

PS The hangars in the background are those at Abingdon. They are seen in some shots in “Masters of the Air “ where much of the film was shot.
