    Thanks everyone for the info. Got the jet today and intend to maiden at a field. I did measure the static thrust at right around 7lbs. Does anyone know what the static thrust of the 1835kv motor is? If you have one- would you mind measuring? Thanks

    Aros, What do you mean, "Not too bad...." She's stunning. I see why you like the BA Version. It is perfect in the glossier finishes. Makes all the difference. Bravo Zulu, Sir. Lucky "7". I agree. Best, LB

    Possible, but appears hard to do consistently from the visuals.

    The F-18 has a speed at which it, before it stalls on you with the nose/wings level, it approaches the glide ratio of a brick. If you ride the edge while adding just enough power not break something in the flare, you could land in that space as the roll out will be minimal on grass.

    I wouldn't try it until I was very comfortable with the jet, personally.

    OOOH Baby, what a sweet looking BA with the Gloss Coat. Took me a while , but now I get the #7 on the tail, but then whose counting.

    Jandro, what CG are you using, is it the same as the manual? I just did mine on my Xicoy CG computer and my battery wasn’t pushes back that far.

    Do I need to set the CG further to the rear?

    How did. you achieve to work in this narrow space?
    Just unscrew it from the wooden battery tray, unscrew the tray itself and you will see that there is quite some space underneath it.
    Once all the wires are properly routed, you screw the tray back in! :)

    Here are some pics of this:

    At least you own a jet that’s less of a hassle and less expensive to operate and maintain. The glass half full effect. Ha-ha

    Yeahhhhhhh buddy! There’s nothing like a glossed up Blue Angel. As an added bonus, the gloss layer helps seal the decals and reduces paint chipping, from my experience.

    Whoa!
    I mean, first of all, I take my hat off, that landing was amazing!
    This said, I don't think you will land the Hornet there.

    I don't imply that you aren't perfectly capable of the feat, just that it looks like a terrible idea as it's very difficult that you nail it everytime and this jet is super-picky and tricky.
    It stalls badly and suddenly, it doesn't tolerate high alpha and it doesn't like to fly slow. If at least you had space for a go around... but you have a tree in the way!

    The LED afterburner really helps out in that regard.
    Still, have you already pushed the battery as far aft as possible?
    I mean, burying the blue-box and clearing the battery compartment allows for a very-rearward placement of the batt:

    Here are a few pics of mine (and here the battery wasn't even pushed full-aft!).
    You can use elastic foam pieces to limit how aft the battery sits (I ended up taking them all out but the option is there to make battery placement extra easy), and you can use a foam wedge to lock the battery in place. If you use velcro on the battery tray + the foam wedge, you don't even need to use a strap, battery won't go anywhere :)

    Hi Eric, was your F-18 the Stingers digital camouflage scheme in the March Mayhem competition ... if it was, it was wonderful?

    I'm just getting my F-18 ready now, first flight in a couple of weeks so not in a position to help.

    I have fitted an Eagle A3 Super 3 gyro.

    Andy

    Hi together,

    my plane is nearly ready for the first take-off. I applied redundancy for the power supply. The electronics and the second battery are mounted on a board to bring them as close as possible towards the COG. However it‘s still difficult to achieve the COG Airguardien recommended.
    since I‘ve no afterburner flashlight, I‘m thinking about calibration weights inside the fans. 2 stripes in longitudinal direction or some weights less in orthogonal direction help a lot.
    what do you think? Is it a good or bad idea?

    Best,
    Eric
