    [QUOTE=Aros;n204609]Here comes #2. I am hopeful this one will have a drama-free maiden with no gremlins. The build was great, everything looks fantastic as one would expect. After range checking and final pre-flight checks, can't wait for her to be airborne! Love this model!!

    Hope it all goes well my friend :Cool:

        Thanks folks! After my Honey Do list is complete, and hoping the glare sky subsides I will be off for the maiden.

          Actually that is wrong - pitch for altitude and power for airspeed.

            LOL
            Thanks Doc. (I seem to be saying that a lot lately) :Silly:And yeah, the decals on the verticals were pretty tough. I guess if you have a knack for working vinyl they would be easy but I seem to have misplaced my knack somewhere along the way. ;)

                As a professional pilot, I respectfully disagree with you. There are two schools of thought on this however, I've never found nor attended your school's "pitch for altitude, power for airspeed." I dare say that it is not the professional aviator's school of thought. Why? Because it is unstable, the exact opposite of what one wants on an approach. If you pitch for airspeed, that now becomes a constant, using power to arrest or increase your descent is now your biggest variable. If I were to use pitch for altitude, I am trading airspeed for that altitude. I am either decreasing airspeed for increased altitude or increasing air for increasing my descent. In either case I have to now adjust my power setting to either not stall, or to not over speed my flaps, gear etc...

                  Lost my BA today on her second flight of the day (5th flight overall). I was at 400' on the downwind when I started a right bank and a 45° downline for a high-speed pass. She would not pull out of the dive and went in hard. Totally destroyed. She hit so hard that a chunk was taken out of the metal fan shroud. I've never had that happen before.

                  I did not loose radio signal, I was still able to bank the plane. But I believe the elevator servos had met their match for torque. I had even turned up the throw on elevator and moved my CG back about 5mm prior to flying today as I felt the book rates for elevator were too low, and the CG was nose heavy. She was still a little nose heavy as inverted flight required a small amount of down to stay level.

                  I had not had any elevator issues prior to this incident. But this was the first time I did a full thrust power dive. She hit at full thrust (no time to react when I finally realized she was not pulling out) and made a pretty nice divot in the dirt. There was even a small mushroom cloud of dust after impact. It was pretty impressive. I have pictures of the crash site, but HS won't accept them. See this post on RCG:

                        If you get rid of the honey that list gets a lot smaller, and you'd be flying by now.

                            Nope, this is a very common mistake.

                              I agree, as long as we are talking about tiny amounts. You want to be in contact with the plane - yes - but not fight it

                                  Unfortunately, most educational advise falls on deaf ears in this hobby.

                                        So another BA down for no reason really? So sorry to hear that, destroyed is the right word for yours.:Angry:

                                        I guess were supposed to sit around and look at them and not even fly, I know there will always be crashes when a new plane comes out but this one is starting to get a bad reputation quick. I don't think I've done a power dive yet with mine after 26 flights so far, don't think I will now.

                                          My Maiden is tomorrow really getting worried now. Nothing is wrong and i have double checked everything but this is just getting worse at this point.
