I just assembled my red star mig-29. The right fan/motor was not running. I swapped the motor and right side still not running. I then disconnected the left side and the right fan runs. It seems that both fans and ESCs are good but if both fans are connected, only the left runs.
I had a Mig-29 when they just came out and I don't remember having to do anything special to get them running. I did calibrated the ESCs initially but that didn't help.
Any thoughts?

I attached couple of images. The Reverse/Brake feature is cool.

I call Motion RC and talked with Tim. He asked me to disconnect the throttle from the Y-split on the side that was running and go through ESC calibration with the throttle trim all the way down. The right side started to work but now the left was not running. We tried this couple of more times and got both side running.

Ok, so I finally came around to writing down my current radio settings (Reflecting a Taranis X9D+, OTx 2.3.10 setup), not so the actual measured travel in mm, that maybe for another day, this is time consuming...
Have to consider: Linkages are all on the factory recommended holes both in servo arms and horns and using the stock servos EXCEPT the tailerons, which I replaced to Corona DS-238MG and installed the linkage on the innermost servo arm hole.

That's it for my radio setup, but here it is "translated" to something easier to grasp for implementation on other Tx:
'ENDPOINTS': All normal maximum (100%), extended 130% for TV and 150% for stabs.
Travel Limits (Triple-Rate)
ROLL 30/35/65
PITCH 35/55/65
YAW 45/60/75
Exponentials (Triple-Rate)
ROLL 60/60/65
PITCH 65/65/65
YAW 50/50/60
(Precision flight/Aerobatic flight/Aerobatics+increased roll)
DISCLAIMER: This is not a final configuration, I am still tweaking things, it's just what I currently use. I basically fly only at high rates so the mid and low rates are probably not set up 'as well'. Weights and expo apply different on different transmitter brands, so don't take the numbers at 'face value'. This setup has 'kinda limited' stab throws due to the use of the innermost servo hole on the stab servos (for servo overload concerns) AND the fact that the tailerons LE rubs with the vertical stabs, but should be 'expandable' with a few adjustments. This served me as a testbed to begin experimenting with the MiG and has worked well so far, but I don't plan on staying with this setup forever.
I will update when I settle on a more mature configuration.
I'm having fun flying with your settings.
I'm thinking of installing TV next.
Is a gyro unnecessary for TV?
Please show me your TV settings.

Ok guys...just got my Red Star Mig and ready to assemble. I've read the entire forum here (and some on RCG). Looks like MRC upgraded the elev sero to 30g (55oz-in) and beefed up pushrods. With TV, do you still think it needs MKS or Pro Modeler elev servos? And if MKS HV69, with the lower voltage requirement, can it run off the BEC (recommends 2S lipo)? I'm using a 10 channel receiver so plan to bypass flight controls directly. Does anybody know if they upgraded the servo extensions to the elevators (soon to be tailerons)?

Hi Sleepdog,
My 2 cents….which I will definitely do when I buy another:
1) Install the heavier gauge wires to the taileron servos.
2) Beef up the foam area around the mains as discussed in this forum.
3) Install the MKS HV69…I use these on all my single point of failure elevator birds. Supply them with the voltage and current they are spec’d for.
4) Install RF chokes.
5) Get the CG back 5 mm aft of mark.
Have fun!

PS Discussing options: There is no reverse HV69, so you will need to rewire the internals. Or…..Install a servo reverser….or buy a servo that fits and has a reverse option. I went with a servo reverser from Futaba. Never had any issues with this reverser. Or….perhaps your radio allows setting up each servo direction individually.

With tailerons you don't need to worry about a reversed servo...
If I bought another I'd use the stock stuff. Maybe upgrade the elevator extensions but I would bypass most of the MCBe and take out the ribbon cables to the wings. Tailerons, crow and rudder air brakes as I have in my current one. But if it come with the reversing ESCs I might forgo the crow. I want a new RWB one but would need to sell my old grey one.
