MiG-29 ✈️ Mildly Boring Flights + Some Cool Inverted High Alpha!
12Shameless plug: if you want to contribute to my work, please consider having a look at some of my merch! ;)

This time the weather was calm and I took advantage of it to train inverted high alpha with the Freewing MiG-29 and also shoot some air to air videos with Tuckie, but the air to air shots are for another day! ;)
The rest of the flight was rather boring but hey... it's not always going to be an airshow demo, right? :p
These were Anežka's flights 180th to 183rd.

Regarding my MiG-29 setup:
*QUICK LIST OF MODS*
- CG 15mm behind factory marks on the wings.
- Reflex trailing edge by 3mm flaps, 5mm ailerons (aprox).
- Reinforced stab assemblies to torsion (Epoxy - thick glass fiber laminate).
- Reinforced stabs to prevent deformation (WBPU - thin glass fiber laminate, 18g/m2).
- Replaced stab servos by Corona DS-238MG.
- Replaced stab linkages by 4-40 threaded rod with heavy duty Du-Bro ball links.
- Removed stock BEC.
- Installed separate 20A UBEC that runs from a standalone receiver battery (2S 610mAh).
- Installed ferrite chokes on ESC-Rx leads (next to ESC) and on the stab servo leads (next to servo).
- I am using the old FrSky Redundancy Bus for everything except landing gear, lights, and everything that goes through the ribbon cables (ailerons, flaps, gear doors), as these need to go through the BB.
- Shortened some of the wires, as I installed the RBus in the aft battery compartment.
I was concerned about the structural integrity of the stabs, and stab assembly so I did reinforce them with glass fiber cloth, which is part of the reason why it took me so long to get the jet ready. I'm not a fan of working with composite materials so I procrastinated a bit, lol. After my reinforcement mods, the stabs seem to be much more solid now. 💕
I took many of the 'well-known' ideas and good practices about this model recommended by other pilot-owners on forums such as RCGroups and HobbySquawk including adding reflex to the flaps and ailerons to maximize top speed and reduce trim drag (unloading the stabs in the process quite a bit) and I replaced the taileron servos by tougher ones, and the taileron linkages by 4-40 pushrods, and FWIW, also installed ferrite chokes on the ESCs leads to the rx as well as the taileron servo leads (to mention a few of the changes).
I also made my own 'quite personal' installation of the electronics and basically rewired the whole thing, changed the placement of the components, added a 20A UBEC, redundancy bus, 2x X8R receivers, the list goes on.
All in all the jet is a superb flier and has an incredible presence. It has some thrustline issues and it is still nose heavy with CG some 15mm behind the wing marks. Good news is, I managed to get the CG there with my heavy Panther Li-Po packs, and before installing thrust vectoring gear, so there's much room for improvement!
