Official Freewing JAS 39 Gripen 80mm EDF Jet

After viewing this thread, it seems most move the CG back from 10mm - 25mm, I guess you all are advanced flyer or want to perform hi alpha. Just curious, does anyone or does this plane can fly normal level with the factory marking CG. I just want to take the bird up with CG factory, trim out for now.

You’re balanced where I am and I have roll and pitch on canards… but I have TV on two of my Gripens and no TV on the third one. No gyro on any and I love how mine fly. Maybe move the balance up a bit and try again?

OMG, maiden nightmare for me..

I added 3grams to the rear, and had my CG about 20mm after the mark and my maiden was almost disastrous. After takeoff ,the Gripen went almost vertical with half throttle, hanging 20 feet vertical from the ground. I had to punch the throttle full, and full elevator down to make it level out...the Gripen was flying but I had to compensate with much down elevator. After 2 loops, my buddy (an experience pilot) took the control and was able to land the plane. I had enable canard with my roll so everytime I try to roll, the plane almost tip stall.

Any recommendation. SHould I just remove the excessive 3g weight and balance the CG at factory marking. That should fly normal, right? Does anyone on this thread able to fly the plane with factory CG marking. Or does everyone here fly it with 20-25mm behind the factory CG. Also should I just disable the canard for turn roll. Thanks.

They changed after the plane was out for about four months. It’s frustrating because all three of mine are the lighter ones and when I bought decals they were the darker ones.

Got my fuse. Only need the steering are and I can get her back in the air.
I bought the decal set to put on the fuse and watch up to the ones already on the wings and vert. To my surprise the new decals are Black, not faded grayish. So I ended up doing all the black decals. I will say the new black decals really make it pop.
I thought at first maybe it was sun fade but after looking at the production images I realized, nope they came faded.

Got incredible high performance out of my Gripen with a 6s 2280kv motor.. Also the current got high... 180 amps...I was 100% sure my telemetry told me wrong....Got the current meassured of a freind...So I was wrong😉 The beeping is I set a alarm when getting under 19Volt, to save things...Try not to use more than a few second on full burst...Still on the stock FW 100 amp esc...

Position lights on the IRIS missiles? Where have you seen that?

i love a good scale or semi scale looking model, but only to the point were i dont know which way im flying in the air when im liek 200m from field, and the Gripen (and i really like this plane) is not known for her outstanding visibily... so the lights are just there for better visibilty during cloudy days, and they are removable, so are the missles...it seemed like the easiest way to mount light with very visible range to the plane

Artistic license added to help him tell the planes attitude and position. I think you can say that anyone that uses those LED lights isn't being scale.

[Evan D]

Yes. I have three Gripens and two (both with TV) have the new EDF unit and reversing 100A ESC. The third is stock, no TV.

I am having problem setting up my FrSky X20/SR10 receiver with the Grippen setup. Can anyone share the model file for me, or any advice. Thanks.

[ArmorBolt]

Hi guys, finally setting up my Gripen with Frsky X20 with a SR10+ and Thrust Vectoring. Does anyone has a FrSky setup or mostly of you guys used Spektrum radios.

If FrSky, could someone help..
For my Frsky X20, when creating new model/Engine 1 channel, next screen.. Ailerons (do I put 1 or 2 channels), Flaps is no flaps, next screen Tail (do I put traditional tail)..
Thanks.
