    1- Welcome!
    2- Where in NC?

    q1- yes, there is no MCBE in this. There is a lighting module, plug each surface in its own channel and mix. I can send a spm file
    q2- yes, search MCBE, but you don't need it
    q3- no

    again welcome

    Greetings from NC, newb here and I have a question about the Gripen. So I purchased a used Gripen from a local guy and I'm having a time trying to get this thing set up correctly. I've watched the "mixing" video on youtube from Motoion RC and the spektrum "forward programming" videos as well. I noticed my old freewing f22 had a blue box inside and wondered if the Gripen should have one as well so I ask a few local guys who confirmed there is in fact a blue box inside when purchased new. when i setup my radio it doesn't allow me to add flight modes to a switch, and if I do, then one of the canards moves its position away from center.

    OK so here goes my questions.

    1. Can I still setup the jet without the blue box? If so then how?
    2. Can purchase the blue box with wiring from Motion? I didn't see it listed under spares for the Gripen.
    3. Does anyone know if the replacement fuselage come pre-wired with the blue box and wires?

    Here's my setup:

    spektrum DX8 G2
    Spektrum AR8360T receiver

    I have the elevon/canard mixed per the Motion RC video
    I have the forward programming per the spektrum videos.

    I've been at this for 2 weeks now, SOMEONE PLEASE HELP LOL!

    Thanks in advance.

    Consider it a mini review of sorts to see does the 3.4kg of thrust with a 6S lipo really add up.​

    So 3.4kg of thrust does sound far fetched and I know it's never going to achieve that when installed, But I can confirm preliminary tests are good. Holding the model vertically and using a standard Admiral 40c 4000mah at storage charge at full throttle it wanted to climb out of my hand when I let it go. I know it's not exactly the most scientific but it definitely feels closer to or even slightly more than a 1:1 power to weight ratio of static thrust. Should make the model feel better closer to and after stall.

    What's the exact EDF + motor+ ESC + battery combination if I may ask? :)
    Hey, flight times around 5min easy with some highspeed passes. No cheaters added.

    Well re-maiden done after her recent crash. Flew with canard rates too high and had her very pitchy on the landing, resulted in a bounce and a plop from about 5 foot high. Lost gear doors, split nose open, bent and tore out all but one gear bent foam around the nose. Got her rebuilt, put in a new Rx with gyro and got the cg back to around the 135mm point and she flew amazingly. Now waiting for Christmas to fit my new fan and motor 😁 while I'm waiting I put in some scale details inspired by Jandro (hope you don't mind) ​​​​​​​​

    Split Screen, 'hands on transmitter' videos of the Gripen, showing some aerobatics in real time and slowmo, and a couple of the formation flights we made for the air-to-air video, hope you find it interesting. :)​

    -------
    Freewing Landing Gear Steering Arm Type A - Metal - N512

    These are upgrade parts for the following Freewing aircraft:
    • Dual 64mm EDF Jets (A-10)
    • 70mm EDF Jets
    • 80mm EDF Jets
    --------
    None of the other types show JAS39 as a special version.​
    i ordered both A and F as i wasn't sure A was right given where the grub screw was on the arm. turns out it was a good idea as it looks like its in fact F you need not A ..
    Will leave feedback on the website and see if i can get the Gripen added to the list of planes under F

    Mine were not facing inwards, but I think that is down to how you mount the brackets into the wings. also the cut out at the rear of the pylons did interfere with the fairing on the underside of the wings but using a bit of heat i was able to shape the pylon around them.
    Agree on the angle inherited from the brackets in the wings. Mine have about 2mm of clearance around the fairing (bulge). Funny!
