Freewing Su-35 ✈️ The Amazing Hover Machine!!
37With thrust to weight ratio over one, the Freewing Su-35 equipped with FMS 1900kv EDFs is a beast to behold!
No other scale EDF jet gets even close! :D
Thanks to some friends that recommended to me these FMS Pro 1900kv EDFs and having moved to newer batteries that deliver great power at a reasonable weight I've finally achieved my goal of getting the Su-35 to hover! Now I need to perform further aircraft setup and gyro tuning to make it look smoother but I am already very happy with the results so far, which you can check and enjoy in this video :)
w00t-w00t ! This power combo rules! :D ❤️
Lyuda, my Su-35 flagship has finally achieved the all so elusive thrust to weight ratio exceeding one! That is, static thrust exceeds airplane weight so I can finally properly hold a hover or extreme high alpha and come out of it with a decent safety margin... ❤️
This has huge implications for my flying, as you will soon realize in the video. I have been trying to achieve such a setup for the past 10 years or so, mostly unsuccessfully. On a few occasions I managed to have setups that exceeded 1:1 T/W but they were so power hungry they totally destroyed the batts and flight time, so it's not just about making it powerful, but also efficiently powerful. Finding the adequate batteries is also tricky because more powerful batteries are also heavier, or short-lived. But thanks to some friends that recommended to me the FMS Pro 1900kv EDF combo and having moved to newer batteries that deliver great power at a reasonable weight I've finally achieved my goal of getting the Su-35 to hover! Now I need to perform further aircraft setup and gyro tuning to make it look smoother but I am already very happy with the results so far, which you can check and enjoy in this video :)
As far as batteries go, there are three different types in use here, CNHL G+ 70C 4Ah and 5Ah... and HRB 50C 5Ah (all 6S). These range between 725g and 830g. The lighter packs perform better in terms of T/W but I think the HRB won't last as long as the CNHL ones. We'll see, I'll keep you posted. The old Panther packs have all perished (except one) at around 120-130 cycles. They served with distinction but their age is over :)

Regarding my SU-35 setup:
This is a fairly modded Freewing SU-35S. It includes a gyro for the TV nozzles to help perform extreme hover and high alpha maneuvers (Stabilizing functions are only turned on for particular maneuvers).
As for the jet itself, the SU-35S is well known for its supermaneuverability features, that are a result of a good aerodynamic design coupled with the use of thrust vectoring nozzles.
The pilot displays a few post-stall maneuvers using the TV nozzles that would be otherwise impossible to perform with a normal jet aircraft.
