  • Do it. After each flight do mechanical trim adjustments of the elevons so you are not messing with the canard or TVs.


    I assume you are considering this since you have limited channels on your TX or RX? I don't have limitations and won't do it on mine but I'm me and you are you.

    Ch1: Elevon
    Ch2: Elevon
    Ch3: Canards (pitch only) + TV pitch (using a 3 way Y cable)
    Ch4: Rudder + TV yaw (using Y cable)
    Ch5: Gear
    Ch6: Throttle

    • I know Alpha said late October but MRC is usually pretty conservative on this (under-promise, over-deliver). Anxiously awaiting a shipping notification any minute now as well as an update on TV availability. Understandably many factors out of their control but we finally have some nice cool flying weather in North Texas.

      • North Texas, sounds like a nice place to live. Here...😖

        • Yikes! Texas is nice about 2-3 months a year (I’m not originally from here). 21C now, but average 35-40 C everyday from April-September . Quite fond of Sweden. My family heritage is from there and some still live in Eksjö. I have been fortunate enough to visit them a few times.

          • I was in Texas in the summer of 1980 when there were 42 straight days of 100F or higher. That's hot, but not like Arizona hot. They are at 144 days and counting this year!

              Yeah, 104° at my house today on the east side of town. Summer is not releasing it's grip on us yet. Either that, or whatever God's been cooking here isn't done yet.

                Piffle, only 104, was 117 at our field two weeks ago, and we’re in los angeles😰

                            • I fly year round, too. Except that in winter, I just fly different stuff. VTOLs and "skidders" and big tired planes.

                                  Who are you asking? Representatives of Motion RC has never posted anything specific on any new plane's arrival date. I've never seen any of them say, "the container is travelling to us at this moment and we will start sending them out on XX month and XX date". What you see on the product webpage is what we all get - "Late October". If you're asking the rest of us, noone knows. The first sign of something happening is when the first buyer gets his "shipping notice". An "idea"? OK, between now and Oct. 31 for N. America.

                                  • I'll take the over/under on seeing the first shipping notice pop out on Oct 27th (+/- 1 day).

                                    • Hi folks,
                                      coming back to the wiring and gyro question. I think best is to use the canards first only with elevator and not with aileron .
                                      The gyro is not connected to the canards. You do your elevon mixing in the gyro, but the canards connect directly to the receiver. The canards receive their signal over elevator mixing to Aux2 and Aux3 in the transmitter. Rudder, Aileron and Elevator go into the gyro, where the elevon mixing happens.
                                      In total you only need one 8 channel receiver and 1 gyro.
                                      In that way the canards are not bothered by the gyro.
                                      Folks, it is open for discussion. An advanced pilot probably wants the canards with Aileron, but not me.

                                        If you don't want the canards as "elevons" and just act in consort with ELE, then you can either "Y" them (might need one servo reverser) and do a single mix or have them separate into their own channels, then do 2 mixes so they act like ELE. The option with the "Y" would need 6 channels. The other option would need 7.
                                        If you only want the gyro on the elevons, then set TX to "normal" wing/tail. Set gyro for elevon. Since you're mixing for the canards, the gyro shouldn't affect them.

                                          Sounds good.

                                          Don't consider pitch only canards a downgrade or inferior solution though - in fact it is the very opposite. Using canards for roll as well is purely a marketing gimmick and far from ideal aerodynamically anyway.

                                          As for gyro, having the operate canards too would clearly be ideal, but I'm sure your stabilized elevon, unstabilized canard setup will work just fine. Just make sure you never have any sort of mode where you remove pitch input to the elevons (since that would make your gyro fight the pitch changes you command through the canards)
