Freewing MiG-29 with Promodeler Servos !! ✈️ Testing the DS150CLHV

- On this video I demo the Promodeler DS150CLHV servos on the Freewing MiG-29 RC jet, these are some serious servos!! The torque and reliability of the stock stab servos are a known achilles heel of this otherwise fantastic model, and for a long time I've got away with murder with a couple of Corona's DS-238MGs as replacements, but it was high time I upgraded to something proper for the bird size. And no, this video isn't sponsored, I paid for the servos myself, thanks! ;)
Promodeler as a brand seems to go to great lengths to care about product design, function and reliability, which is what attracted me to them in the first place and to finally make the decision to pull the trigger. I also appreciate the wealth of knowledge that Jon made available at the ProModeler site! :D
I haven't yet put enough flights into them for me to say that they are the best thing around since the advent of molten cheese, but from all the information I have been able to gather, I am pretty confident these are some of the best servos you can get in this weight and size class (if not the very best), particularly at this price point.
So far, I haven't yet made the proper modifications on the aircraft to run these servos at high voltage, which is kind of a waste of their potential and I'm sure John Beech from ProModeler would rightfully scorn me for it, but it will be done in time. And for the time being, the very change of servos already allowed me to feel the jet being a lot more locked-in and I also managed to increase the throws without fear of putting too much load on the servos. Maybe it's harder for you to tell from the video, but I did notice indeed. The extra throws are super important for me, since they are paramount to my style of extreme post-stall flight. ❤️
These were Anežka's flights 256th to 258th.

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 first by Corona DS-238MG, and then ProModeler DS150CLHV.
- 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.
- Removed the toe out on the main landing gear struts by filing the chamfer on the axle pin that connects strut with retract.
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.

Those fans are terribly out of balance :)
I had Promodeler DS150CLHV in my Mig-29 since the very beginning. Never had an issue. Great servos!
They aren't out of balance. It's the LiPos that are half dead and cause the engines to de-sync
Very dynamic exhibition! Now I thinking to buy one even as a memory for ours which are no more ours!
Just have at it! It's too great a bird not to have it! 😁
Pushing a the limits!! Great job man 👌🏻🙌🏻
That's my shtick! 😁😁😁
Thanks Nir!! :D
2:26 it was a little scary :-)
Yep, that's a Kulbit gone wrong in a nutshell!! xD
That's why I usually fly that maneuver pretty high, so I have altitude to spare in recovery!
Floating it in!
w00t! :D
Great 👍 Flights Ace
Thank you!! ;D
So do you like the promodelors? Just ordered some ds75clhvs for a 3d foamie build but there is kind of a lot of forum drama around the brand which makes me a little worried.
Yes, so far these have been great on my end, although I haven't put many flights into them yet!
FWIW, the only issues I have heard about were some instances of stripped gears on the smallest models, particularly when used for tasks where they were undersized.
MAD SKILLS BROTHER!!! What mah battery are you using? Peace
Thank you! :DDD
Tell me have you solved the issue with having weak elevator control to where you can't go into steep dives?
I have the same plane and already overtightened and stripped the elevator control horn
Pretty much. I talked a lot about it in RCGroups in the early days. There are many sinultaneous issues at play here, mainly weak servos and linkages with stab assemblies that give in to torsion and stabs that bend themselves. In normal flight it's a no brainer, but when deploying flaps, the extra load on the control surfaces was enough to stall the servos, and even if they didn't it could all bend so badly that users with limited throwa may also have been unable to recover. Nose heavy CG made it even worse. Fixing just some of these will help, but tackling them all at the same time os the way to go IMO.
@@RC4ever can you please tell me what you've done exactly? Replaced servos, replaced servo leads? Bypassed the y harness?
Fiiiiiirst ❤❤❤❤

Do you need to upgrade the bec with those servos?
Well, I had already upgraded the UBEC before installing the servos. Even with stock servos I think this one is better served with a 20A continuous UBEC. Some may say overkill, but I like playing it safe. I also run it of a spare 2S 1000mAh batt.@@EDF_FANatic
