    My elevator is actually set up to the high rate value in the manual. I think I said it was 100%. Hope to get some more flights in today and some better video.
    It would be nice to see videos of others T-45 flights.

      Experimented a little today with CG and the new slimmer Admiral 6s 5000 packs. Slid the battery back about 5mm or so from the front bulkhead and she was just not too happy. I didn't like the feel of it.
      Put the battery back up tp the bulkhead and locked her back in for some good flying. After cycling the new packs 4 to 5 times, she lifted off the grass runway with no problema. Couldn't be happier.

      I ordered the inrunner unit for it, but honestly I do not think she needs it. I may see if I can get Motion to cancel that order for me.

        Maidened the T-45 today! (yesterday now I suppose)

        Winds were mostly calm and temperature about 85F.

        Stock PNP outrunner, Admiral 6s 5000 50C (new version), FrSky Taranis X9D plus with X8R receiver and FLVSS voltage sensor.

        Flight 1 I held the nose on the runway which delayed takeoff and caused an over rotation. No trim required. Felt comfortable enough to do a low pass. Almost hit a pine tree later in flight.

        Flight 2 was 2 aborts and a short flight due to a fresh battery that had not been cycled. The battery was quite warm on landing. Changing to a battery with more cycles for the third flight made a big difference.

        Flight 3 saw a better takeoff due to proper soft field technique and plenty of power and speed.

        I flew the Admiral 6s 5000 all the way forward against the nose gear bulkhead. She required ZERO trim. I could not be happier. Planning to fly her tomorrow and Sunday before the weather goes bad here again.
        Super big congrats!! Love this plane but hate the paint scheme...
        I have way too many planes to list off... But I love to fly them all! the 80-90mm Jets are my newest addiction! Also check out my youtube channel for TONS of flying footage. https://www.youtube.com/user/gooniac33

          Nice flight and that field is cool!! The grass is like and arrestor hook on landing. I too feel as you do about the inrunner set up with this plane. I know a few people that have it and don't feel like it is worth the swap. You need to change the timing on the esc to low in order to make the battery last anything near what stock does and when you do that it loses performance. As I stated on the other thread... The FMS inrunner is looking really good! They don't consume too many amps at half throttle but still move lots of air which is what is needed. Gonna keep fiddling.

            You know I just went with the ESC settings out of the box. What timing should I be running on the stock motor?

              With the outrunner I think that it is ok to leave it on default. But when you upgrade to the inrunner there are people that have had issues. It isusually on high timing which just causes it to more amps and heat up. Lowering it helps with amp draw big time.

                Got a couple good flights in on the T-45 yesterday.

                On flight #8, the 4,5,and 6 minute callouts are actually 1,2,and 3 minutes. Forgot to reset my timer.

                  Hey Seaviper your T-45 looks great! I've got mine assembled and setting up the throws. Did you mix some down elevator with the flaps and if so how much for say low rate flaps vs high rate flaps. I'm running the stock PNP setup for now. Any other recommendations or suggestions are welcomed!

                    Hi 109pilot! I don't have any mix at all as far as flaps to elevator go. Don't think I need any. I am running 15% expo on the ailerons.
                    You will find that the T-45 is very easy to fly and to land. In my case I have to get the nose off the ground and let her accelerate out of the grass. I use 1/2 flaps for takeoff. Full flaps + slats for landing. The sound is awesome. Mine is bone stock PNP. If you are flying the new long Admiral 6s 5000, then push it all the way up to the nose gear bulkhead. It's a lighter battery. My old 5000's were about an inch back from that bulkhead. But they were heavier.

                    I have a video on my channel about the setup I use. Good luck with your first flight! let us know how it goes!

                      Hi Seaviper!
                      Thanks for the info! I think I'll set mine up identical to yours since you've had such great success! I was going to put the flaps on a 3 way switch and mix the slats in. I'm hoping to maiden once everything looks good and checked twice. I have the big P-38L and love it as well.

                        My T-45 went in today after 10 previous uneventful flights. As it reached an attitude of 10 feet the motor quit and all control was lost. It went in as I had no control over power or control surfaces. The plane is basically a total lost with maybe gear and a few other parts salvageable. After picking up the pieces I plugged in the battery that had been fully charged this morning and began to check out the controls for a response. All surfaces responded to transmitter inputs as well as the motor/fan!!
                        Now, the question is WHAT could it have been to cause this crash. The RX, Battery were working fine in the two prior flights today. The batteries had been carefully broken in with 10 previous gentle 3 minute flights to date. I'm at a loss for an answer and am reaching out to fellow T-45 Motion RC pilots!
                        Thanks, John

                          Sorry to hear that jpjet. I would try running that motor/battery/esc combo on the bench at full power for a few seconds and see what happens. On my ship I use an onboard voltage monitor (Frsky FLVSS) which gives me a visual indication of each cell prior to takeoff and then it reports back to the transmitter. So I have voice alerts for low cell issues. Could have been a battery issue or a connector issue. I would look into my connectors and /or solder joints for the power cables.
