  • Using an Admiral 5000 6S. Battery placed all the way forward, landing gear down .... and plane is still a bit tail heavy. Are most people adding some nose weight ?

    Thanks. Bob

      Mine balanced correctly with a 6s 5000 lipo and no additional weight was needed. Note that different batteries have different weights and some aircraft might indeed need a little extra weight.

      • Hi, I'm installing new main gear doors after a crash, and I don't know where to insert the clevises and pin into the servo and gear door. The manual didn't really help me all that much. I would greatly appreciate it if someone could post a photo where both ends are inserted. Thank you so much.

        • I'm competing in our Belgian F4H (World Air Sports Federation aka 'FAI' flying scale model aircraft) championship with the B-25. After a top score for the first flight despite a "too fast' comment from the jury, for the second I tried to be more scale. Unfortunately, it was too slow for the bird and the take off did not end as expected...
          However the jury found the take off very scale this time.
          So a new bird and spare part (mid wing section) were ordered and delivered. The nacelle and fuselage, I'll try to repair them and convert the B-25 with the 3D gunship nose version because the front of the fuselage is not symmetric anymore. This will become my trainer. The new one will be my competition plane.

          Never give up!

          Regarding the CG and weight, mine is with recommended CG and 4.170 Kg, I'm using the Admiral 5000 (730 gr) batteries and I need a bit of extra weight in the front.
          I fly about 9 minutes and I have a bit more than 50% left in the battery.
          What I noticed after about 10 flights is the engines started to move in the nacelle one after the other... check your screws, they get loose!

          • LucB, Both a Congratulation and a condolence are in order here ti would appear. Glad to read you're rebuilding her. Nicely done on the "Top Score". Best of luck, LB

            • I have some experience with various planes. The craziest I have I flown are the Lippisch, a timber x and the little voodoo p51 and have a bunch of easier planes. How difficult is this plane to fly with some experience? The realflight has a nitro B25 and I’d say it flys quite nice. I wanna get one but aren’t sure I have enough experience yet.

              • Justinhip, Welcome to "The Squawk". Glad to have you onboard, Sir.

                This airplane is considered 'Intermediate Level'.

                Only you can decide if you're ready, though if you fly at a club field or a public field, you can ask for a little assist.

                Best, LB

                  Seems like a significant step up in size from those listed. It requires power to fly it to the ground.
                  Buddy box with a proficient flyer and you could learn to handle it.

                    It is not difficult to fly, thanks to the 2 engines (I have more difficulties with my single engine electric planes). But you need to remember that it needs to fly a bit faster than scale speed.
                    Here is what I do for the championship (keeping in mind that I have to be as scale as possible):
                    throttle stick at 55% is the low limit to fly safe. Apply more power for take off and let it roll to get the required speed (75% throttle).
                    The low rates are my max rates, 60% expo.
                    In normal condition, windy or not, there is more power than needed and I fly it like a hunter.

                    Extra note: my new B-25 came with V2 version of the Esc. These have an additional wire which seems to be for the reverse.
