Official Freewing JAS 39 Gripen 80mm EDF Jet

[Evan D]

I have all this info in the RCG thread.

The TV unit weighs 164g. The stock back part weighs 74g. Extensions are 17g.

The TV unit robs about 10% of the thrust you have with a non TV'ed Gripen.

In my opinion if you want more than 1:1 you need to go 8S.

Hi, I'm thinking of getting the Gripen as ARF version. Ideally I want an EDF to get a thrust to weight ratio above 1. With the EDFs I checked it seems to be a very close call to get there. My question, how heavy is the ARF Version? Motionrc states 2350g for both Version PNP and ARF. How much extra weight would the thrust vectoring set add?

Thank You and best regards

PNP...

Hi I have a question about the TV for the Gripen. To install it do I need to buy servo extensions or is the TV a pnp upgrade?

Always thought FW should have made this a 90mm bird from the get go :)

Great job!

My Gripen has had a great life and was already highly modded. So I was switching all my TX RX over to FrSky X20s and....well I decided to go from 80mm 8s to 10s 90mm. (lots more modding) Just had my first 6 test flights and decided to do as speed check because its moving really fast....

Very nice, but it needs an afterburner.

VERY artistic and well done. The snow in the background is a nice touch.

So much helpful information in that post. Thank you very much!

I installed the fms 1900kv fans in my SU35 over a year ago, sound good, perform well. I looked at the gripen but decided against it as I already had the SU35. I bought my SU35 by buying the parts and adding my own servos, fans, escs etc, worked out about the same as buying plug and play but with better components so if you are happy to `modify` to achieve the best results then SU35 is a good option.

Nice flights! (cept the crash :) ). You got a lot of experience with the su 35 and now with this one with TV.

Thanks!

Wich one do you prefer if you had to choose one?

Su-35. It's barely even a contest. (IMO)

Pro Su 35: Cheaper and looks extremely nice.

That's correct.

Con: Sounds horrible, made of light but crappy material

That's incorrect. Sound depends mostly on the fans, and the stock fans are doodoo. Get the ARF and install your own stuff. With FMS Pro 1900kv fans with HW 80A Skywalker ESCs you'll get great performance and sound on the Su.

Crappy material? Certainly not. If you ask me, the old EPS used in the Su-35 is widely superior to all the EPO crap we have nowadays.
Yes, EPO doesn't get dinged and scratched as easily but it's extremely heavy, not really rigid, thicker walls need to me made to compensate for that, the planes that come as a result are underpowered pigs for the most part and it doesn't stick with epoxy, which is my favourite glue for structural repairs. So no, certainly not crappy. EPS is extremely light while still providing awesome mechanical properties. It's sad to see it being abandoned as a material, if you ask me.

Pro Gripen: Sound better. Probably longer flight time?

Sound mostly depends on your fan, again. And I certainly wouldn't recommend the stock setup either so this point is moot.
Longer flight times? Not by any chance if you intend to improve Gripen performance. The stock bird flies about as long as the usual Su-35 setup. But if you go to more powerful Gripen setups, flight time suffers much more. Su-35 kicks the Gripen's ass in endurance any day. It also is a more efficient design as far as gliding goes. The Gripen is a brick.

Con: Tends to wiggle around a bit. Costs more.

Also correct.

But the real Gripen pros are:

Has the easiest to handle high-alpha features, extremely easy to land, easier to upgrade to 8S, takes quite a beating during crashes (SU-35 gets the intakes crushed, but Gripen has them sideways so it has better survivability), etc.

Both are fantastic aircraft and I recommend them both... but if you need to choose between them, for me, the Su-35 is the superior aircraft in most regards.

As far as Su-35 sounds with the FMS 1900kv... check it out:
