Freewing Su-35 Twin 70mm 12 blade

[Airguardian]

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.

Has anybody tried the new high speed version?

What new high speed version. New is a relative term, if you mean the 12 blade fan then its an outrunner and was around more than a year ago, New in current terms is a 9 or 12 blade in-runner and I have not seen an advert for one ?

After Motion telling me the new version came 100amp esc's I ordered the SU35 only to find after getting it that it had the old 60amp esc's. I have returned the plane. I can't understand why they upgraded the motors and not the esc.

Look under the spares tab, find motor it states max 55amp motor, 60amp esc. it is a 12 blade out-runner. Never used them as I wanted fms pro in-runners so I dont know tested output figures..
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.

Ok, now that sucks.
They could have at least used the 80A ESCs instead :/

With the stock setup and the new power units, is there a need for the 80A's?

The MRC ad clearly states 60A ESC.

Power System	2x Brushless 2952-2100Kv
Speed Control	2x 60A Hobbywing, EC5 connector
Propeller / EDF	2x 70mm EDF 12-Blade

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

JLambCWU how did you make your 2 seat cockpit?
I'm planning on building an SU-30SM using the SU-35 as the base, so a 2 seat cockpit is a must

New air-to-air adventures!

[Airguardian]

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

Depends on how you define "flying". Maintaining speed and attitude control is flying.

The original reference was to the Su-30 and F-14, not the Space Shuttle. These two can't be controlled in a vacuum as they lack attitude actuators that would do anything in an airless space, so I stand by my previous statement.

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!

Thanks for the info. I completely understand that they are different airframes and therefore have different flight characteristics. I was honestly looking for information like you gave me about the battery tray and the fuselage flex, stuff that you don’t really know until you ask on a forum.

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

[xviper]

The confusion is from asking to compare the F-14 with the Su-30 in the Su-35 thread. Apples, oranges, and mangos!

I see what you're saying now. I guess when you don't really know what those planes are like as models in real life, apples, oranges and mangos all look the same (like to a blind person). You have to taste them to know for sure.

Not if you fly in a vacuum. A feather will be just as fast. 🤣

It is a bit confusing but it's also a fair question when asking about a comparison.

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.

Yes, my dual batteries total almost 1200g! I flew two flights today...first was doing everything fast with big vertical maneuvers with timer set at 4 min. Second flight was everything slow and sedate with timer set to six minutes. Batteries at about 15-20% at end of both flights.

[xviper]

Asking about the Su-30 in the Su-35 thread confuses folks. I fly an Su-30 and it's a dog in stock condition out of the box. I've mod'ed mine so that it flys very nice. It's a heavy beast....mine is 11 lbs now!.

So you're saying the Su30 and F14 would be faster in a dive then?

As would be a cannonball.
