Official Freewing 70mm Yak-130 Thread

Thanks for the details. :)

[Ron1950]

its the 12 blade fan from the super scorpion I beleave it has a 2850kv motor from bangood but I used a ZTW85 amp esc .... I think motion is using a 2750kv motor ;)
..maybe Jon can help you on the specs better after I install something I forget all about the stats

[Prowler901]

Dang! This looks like a fun jet. What 4S system did you put in it?

[Bajora]

Thanks Ron... With only one pilot, yours should be slightly faster than mine.:p

A guy at my field just bought one and yep, one pilot only.

[Ron1950]

Bajora you sure must have some nice camera equipment...always great vids and stills....we had a guy here in Killeen that took great stills etc but if u crashed he was always the first one there snapping away at the wreckage lol...hes a army helo pilot and got sent to korea and will be back soon I hope I need pics

got my yak arf+ and installed the 12 blade 4s set up like yours and to make it lighter freewing only puts one little Russian in the cockpit

[Bajora]

I currently have two of these flying right now ... a 6S stocker and a 4S that uses a FMS 70mm 12 bladed fan. I love this model! I still fantasize about getting its larger 90mm ReadyToFly version but for now, this one scratches my itch.



That V2 Venom in the popping Red Swiss scheme is a looker too!



Some of you probably already saw this video but I will share it here again anyway:

[AkumaZeto]

LEt us know how it goes. This one is on my short list to that or the scaled up ready2fly one.

[Ron1950]

UPS delivered my yak arf+ yesterday and guess the new style is only one pilot...wonder why? cost reduction? lol

[Flygirl]

I didn't do it with the Yak but I did make the same mistake on one of my 250 quads. The quad had XT60 connector and the batteries I bought were Dean T connectors. Doh!!! Luckily I had some plug in converters. So, you're not alone in being blond. ;)

[Ron1950]

am I the only one dumb enough to do this? bought the yak130 last week with a 6s battery with ec5 connector as the specs page and the note on the description page says...I install the battery and I have a t connector on my yak not the ec5 as stated all over the motion page lol....they will take care of me I am sure but no flying for at least a week probably. not upset just disappointed lol

6/2 this web page has been fixed to say T connector all around thanks

Here is a great article on installing the Top Designs CNC aluminum gear on the FW Yak-130

Just received mine last Friday after ordering Tuesday evening after 5PM CT. What took so long ? LOL

MRC continues to amaze with their mastering of supply chain logistics.

This plane was the easiest ARF I ever assembled and there's been plenty. It took all of 45 minutes to put together and another
30 min. putzing with the DX-9. Almost everything is pre-assembled. Screw the wings on, glue the H&V stabs on and she's pretty much RTF. The servo rods were even connected. Felt like I was not needed. Ha

A lot larger than I had expected. Not quite as long as the FW 80mm F5 but side by side, she's formidable. The 6S stock setup has beaucoup power.

Can't wait to get her flying!

The Freewing Yak-130 is my favorite plane to fly. Looks good, sounds, good, easy to land, handles crosswind landings great (w/no flaps), easy to see. I fly with 4000mah 60c batteries and the 3300mah 60-120c. The lighter battery lands the easiest and I get about 100mph with the wind. 4000mah battery lands faster. 4000-6 minutes, 3300-5 minutes. Only visual detractor are the gear. Simple wire but can take anything you throw at it. Great first bigger EDF.

anyone tried these scale like struts? Top-Design CNC Suspension Strut Set For Freewing Yak-130 70mm EDF Jet

RE: Freewing 70mm Yak-130

Love the Yak 130. I have to ask how will the performance of this 6 cell 70mm dual exhaust model compare with the [font='pt sans', sans-serif]Freewing F-35 Lightning II 4cell 70mm TV.[/font]



[font='pt sans', sans-serif]A side from the post stall manuves of the F35's TV. Will the Yak have much the same vertical? Is the duration with the lower amp draw significantly longer with the Yak?[/font]

Konrad,
Do you fly the 90mm Yak 130? I have had little luck keeping this bird in the air, and have tried different motor/bat combinations, even a 105mm fan/motor but cannot improve the power to weight . What would be your mod. to improve p to w?

Sorry I know nothing of the 90mm Yak 130. But if you can post actual amp draw and fan rpm number from your particular set up some of us might be able to help.

RE: Freewing 70mm Yak-130

Thanks guys,


Is there actually more power or more to the point an increase in the power to weight for the Yak vs the F-35.
I fly this 2200kv motor behind the 6 bladed 70mm on 6 cells in my Su 35 I’m drawing about 46 amps from this set up (6k feet altitude).
As we know Power = Amps x Volts so in simple terms I’m assuming we should be seeing close to 1Kw (46A x 22.2V)of power from this Yak 130 set up. 
For the F-35 I’m assuming a 38 amp draw and 14.8 volts for about 5/8 of  Kw.

Now based on the advertised weight 1.7kg vs 0.9kg the 4 cell F-35 should have a better power to weight ratio.  So by my math things aren’t getting better. Add to the fact that the bifurcated exhaust isn’t as efficient, I have to ask is the Yak a better performing model and if so why?


So what am I not seeing, or on the flip side what am I seeing that is not there?


All the best,
Konrad

The Yak-130 has nearly unlimited vertical. It is faster than the F-35 and is very maneuverable. While it won't do some of the 3D maneuvers like the F-35 can such as an inverted flat spin, the Yak-130 can perform all maneuvers that the full size aircraft can perform. It is a very fun plane to fly. Simple, yet exciting!

RE: Freewing 70mm Yak-130

Yes indeed, finally a 70MM that takes a 6S cell. This should fly fantastic, now they're getting close to things I enjoy; POWER! Fact is it's much easier to pull out of trouble, then fly out of it. For instance, would you accelerate from a guy running into the back of you? You betcha, Also, power can be used inverted for RC to take you out of a conversion instance or spiral! The problem is thinking to do so, people like me panic and forget some basic rules. There for, POWER is an alternative way to fix a weakness or lack there of. The Red color is also easy to see! I think highly of the military scheme, but it's made to hide from the competitor. That'd be me when I'm flying! Ha ha. Well, gents! Enjoy these new birds, they just keep getting better and better!
