      This one is a 4' wingspan. So I'm looking at going with 3s power. I'm hoping with the smaller motors I can mount them in the rear and keep a respectable CG setup. So far it seems to be working.

              Good news! Power system is installed! Just a couple more pieces and she's ready to test also added a crow mix for the drag rudders

                    Question of the day is, hand launch, or throw the gear under it :D

                        Thanks will see if it makes it to the air today. It's cg is set to what the flying wing calculator says so hopefully we see success

                            Gear ads weight and wings land well as belly landers. You could make a launch cart for it to fly off from and belly land it if you have a little pavement to roll off . If you decide to hand launch mix a a few mm's of up ele to launch as wings tend to dip before they get on step. I use the spring trainer switch so I can dump it quickly with one hand as I throw with the other.

                            good luck !

                              Hand launch i can't get enough elevator to get it flying. Doesn't dive but just doesn't have the elevator in time to lift her off

                                I saw a few YT videos where the guy had some kind of a rail take off platform. He built it at an angle and the wing would shoot straight up in the air.

                                Your project seems very good, for now its a C until you make it fly, pending a possible A, and if you land it with no scrapes is a 100% and a cookie.


                                Kudos my friend, I leave the building to others, I do the flying and crashing...

                                  Maybe with the down thrust angle it would be necessary to add additional "launch up-trim" till she gets on step. Also ck the cg is on w zagi method . Keep on keeping on, kudos for taking this on yet again. Happy landings.

                                      Also think my battery I'm using doesn't have the capacity to run both motors as one slows down rapidly after only a couple seconds running. So I'm gonna look at better battery size and c rate

                                        Rifleman......that statement just :Confused:me. If you are running both motors (ESC's paralleled) with one battery, how does only one motor slow down :Thinking:

                                          I'm not sure what it is. I've already changed out one of the escs still did the same, unless I have a motor going out
