Your SU-30 has really put on weight. Is it that extra battery? I would love to put in an FMS 8s power system but then, battery space would be an issue. I'm not willing to carve out all that foam and eliminate the airbrake. I love that airbrake. 😊 I'd still like to be able to fly it for 4 to 5 min.

AndrewF, it's not just the weight, it's how the plane is designed and the layout. The Su-30 from HH/FMS/E-Flite has the battery compartment so far forward there is just no way you can get a decent CG with a decently sized battery pack. You either fly super-nose-heavy or super restricted in flight time. Plus the whole fuselage is known to flex a lot under flight loads which is less than ideal. The plane itself flies well and people like it, but the Su-35 will always kick its ass as it is.

Can't fly in a vacuum!
Maybe you meant to say "can't develop aerodynamic lift in a vacuum".

Spares are cheaper too, if I recall correctly... so there's that. ;)

When I upgraded to the FMS PRO units I put in 80A Hobbywings.

They dont do arf version so 18 months ago I bought airframe from spare parts list then added my own fms pro in-runners, twin Hobbywing 80amp escs, different servos, landing gear etc in order to get what I wanted. You might consider this route, you just have to spend a air bit of research time looking back through this thread and the answers are all available.

Paul, the Su-35s that came in the latest container to the US warehouse now ship with 2100kv inrunner motors, so they are indeed upgraded in that sense.
I still think 60A ESCs is borderline for these setups. Particularly if you want to get all the juice out of it at high timing, they may be more prone to overheating than higher amp-rated ESCs.

I commented on the other forum that this seemed unusual given the AL37 and Me262, which have the same powerplants, both still shipped with 60A. Jandro was excited at the prospect of some extra headroom for the PNP, but I see this has now turned to disappointment lol.
I can see his point - both the airliner and the schwalbe have better airflow arrangements for the ESCs than the sukhoi does, and are (one would hope) less likely to be drawing lots of power in a post-stall condition.

Jandro I read EU warehouse 60amp at the moment with outrunner. I agree 60amp borderline, my post just answered haljennings question about why motion r.c did not upgrade esc even though it would have been better at 80amp. I was putting myself in Motion r.c. shoes current us version as of now states Version Info: This is the High Performance version of the Freewing SU-35 Desert Camo. This version includes two powerful 2952-2100Kv brushless inrunner motors with 12-blade fans, and two 60A ESCs for exceptional speed and performance. I dont know what power/thrust this fan produces, if indeed the website is correct ? Its a bit confusing and needs sorting out.
found this to add to the confusion ;- if correct needs 80amp esc so motion website probably still not correct ?
Motor Type Inrunner kV Rating (RPM/Volt) 2085kV Maximum Watts 1580W Continuous Current 68A Maximum Burst Current 75A, 10 seconds Recommended Battery (Input Voltage) 6S (22.2V) Recommended ESC 80A Recommended Propeller / EDF 70mm 12B metal fan Slots, Poles 12, 4 Shaft Diameter (A) 4mm Shaft Length (B) 16mm Motor Length (C) 63mm Motor Diameter (D) 29mm Overall Length (E) 79mm Weight 183.4g / 6.46oz Connector Type 4mm Bullet
