    Has anybody put EFlite/FMS main gear struts on this jet? I've seen Brent Hecht's video with them and it looks amazing. Thinking of doing 90 degree rotating retract units - maybe the ones for the A-4 Skyhawk. Does anyone know if those will fit? Screw hole spacing the same? I'm determined to make this work :)

    Hi All ,
    Lucky to have stumbled across this post. Just placed and order for a Blue Angels version , will be dropping a Xicoy45 into it for a turbine conversion .

    Couple of questions straight up that my research hasn't' found me the answers ..

    1. What turbine conversion kit does people recommend . I saw the BIGBOYRC , doesn't seem to do it anymore.. The NOVAJETS site is down .. So far my best option is the TOP-Design version.

    2. What size main wheels are the Hornets.. I need to put electric Brakes on it . so want to order the same size Main Wheels.

    3. Anything that i need to know / Modify Straight up on this Jet ? 290 pages .. im on page 14 .. ill Keep reading each post but a breakdown would be Great.

    Thanks in Advance..

    Brgds
    Michael

    The new FW reversing ESC (which appears to be the same as the Hobbywing Skywalker V2) is in several new and updated EDFs from Freewing. If trying to program it with the programming card, the current one listed on MRC's site doesn't work. No new programming card is listed yet. If programming the ESC using the transmitter


    Hi Hugh Wiedman I think the mystery has been solved by MRC tech support. The issue might be the battery connector i'm using. I purchased a parallel connector instead of series. This makes sense. I'll confirm once the new connector arrives.

    Thanks, LB. This was V2, just "eyeballed" and dremmeled (is that a word?) from a small block of basswood. I can easily remove it for a V3 or V4 version, if I decide to go that far. For now, it'll work.

    Cheers

    This is only a guess, but have you recalibrated your throttle? I fly off grass as well and have 2 F-18's, both still on 6S with the 12 blade 4068-1835 Kv inrunners and they get off very quickly on a single 6S SMC HiV 5900, so yours on 8S should be even better. I did convert 2 F-4's and my F16 to 8S with the same fan you are using in the F-18 and fly all of them on the SMC 8S HiV 5900 packs. Those "rocket" off the grass so I would think your F18 would also, especially since the SMC 5300 packs have a slightly higher C than the 5900's. I felt the F18 on grass with the 12 blade 6S fan flew just fine (and didn't want to add any more weight in using an 8S fan and battery) so I have yet to convert the F18's to 8S.

    If you can, put a power meter on and confirm the amps and watts drawn. If I'm not mistaken, my 8S fans with SMC HiV packs are drawing about 138 Ah and 4300 watts at full throttle with a fresh pack (static on the bench). If you're not close to that, you are not getting to max output. Let me know as I'm very curious to find out how the F18 would be on 8S, as I'm loving it with the F4 and F16.

I had to order a small Du Bro connector pin that came today, so once I had it in hand, the finishing up went relatively quickly. There's always a bit of fiddling to do on these things like servo travel, checking security of the mechanism, and all that. But it is well worth doing, for me. I have put a movable tail hook in my F-14D, A-4E, and a Grumman F6F Hellcat years ago. This one is not stressed to actually "catch" the airplane, but I'll probably do some photos of it in the air with the hook down, just for yuks.

    Any ideas to why the power is anemic? I'm more than happy to provide additional details if anyone has any ideas.

    Credit goes to Elbee. This is his design and it works very well! Thanks for the kind words, Aros. I’m a newbie trying to learn 3D printing.

    After getting my 29th flight (3 on this new airframe with the innards the same on all flights so far) I am now looking out the window at the white stuff coming down. But I'm taking advantage of the down time to work on my AIM-9 Sidewinder missiles that I am learning to 3D print with my Prusa mini. These are from the files of Dirty D in 1/10 scale. So, although maybe slightly larger than scale (1/10 versus 1/11 of the model), that difference is really indistinguishable when they are mounted on the wingtips.

    I still have scale nomenclature and markings to put on the missiles that I'll have Callie print up, and then they should basically be finished. I plan on doing some test flights with these missiles mounted next week when the weather gets better.

    A Big Shoutout to LB for his continued support of getting me up and running on this new medium of model building!

    Appreciate your excellent advice, as always, Evan! I did check the tightness of the bolt holding on the fan blade. It was not loose, but didn't hurt to tighten in up a bit more. And although there wasn't a piece of plastic loose, which it certainly could have been, that piece totally missing seems to be the culprit and will be corrected on the next flight. I've done a few full power static runups with my replacement piece that I fashioned out o f.010" styrene. So far, so good. We'll see how it fares on the next test flight early next week!

    Cheers
