  1. The first flight was successful. The Hacker consumes 56 amps at full throttle.After 5 minutes of flight time, there is still 72% remaining capacity in the battery.You can do wonderful classic aerobatics with the Messerschmitt.With the Hacker and 6S, the turn goes endlessly upwards.At the first interception I was afraid that the wing would break because of the hard balsa spars, but nothing happened.The M23 from Sarik Hobbies is a very beautiful model and immediately catches the eye.Congratulations to Jim Newberry
  2. Now the M23 is ready to take of.The Hacker A50-12L V4 consumes 56 amps at full throttle.Let's get started
  3. Finally the radial engine dummy is printed and I was able to weigh the model. 3770g is the total weight with Lipo 6S/5000mA and I am waiting for good flying weather. My friend Christian has printed the engine and is happy to provide the data
  4. However, I have already paid attention to weight reduction during assembly and have not always used the parts from the kit.The first flight was therefore successful and I will report on it when the model is finally finished.
  5. Hello, I haven't weighed the model yet. When the radial engine dummy is finished and mounted, the center of gravity has to be rebalanced, then the final weight will be known, at the moment the M23 weighs about 3,5Kg.
  6. The M23 is ready to go. Dummy engine is still in progress.
  7. The Dauntless is quickly assembled and is ready to start after approx. 1 week. The building instructions are international and anyone can build the model.At the moment the airfield is still too wet and you can't fly yet. A flight report will follow later.I don't know if you can get the kit in England. If you do, you get a very nice model at a good price. In Germany the Dauntless is distributed by D-Power. The Engine is a AL4206 by D-Power.
  8. In the picture you can see the distance pieces for the cowling.When fitting the cowling, I used a trick so that the propeller sits approx. 3 mm in front of the cowling.In Germany we call this the cardboard method.4 cardboard strips with a hole of 3mm diameter are attached to the fuselage so that the holes are exactly over the distance pieces of the cowling.Then simply slide the cowling over the distance pieces and drill the holes.That"s all
  9. The Dauntless is designed for a 6S-Lipo, which is mounted directly at the front of the motor former.There was an unpleasant surprise when weighing the center of gravity. 300g of lead in the cowling would have been necessary to achieve the correct center of gravity. Clearly too much.So there was nothing left to do but to saw a cut-out in the engine former.Not very nice for an almost ready to fly model, but possible.Now the Lipo could be pushed forward 6cm
  10. Hope, I have uses the right words, but the images show more then 1000Words
  11. The spacer sleeves for installing the electric motor were unfortunately 10mm too short, so I simply used two bearing crosses made from 5mm plywood.
  12. The 3 Cable are for aileron, flap and undercarriage
  13. Three cables come out of the wing to the receiver, so 6 cables together, which was too complicated for me, so 3 cables per wing are in a multiplex connector.
  14. You can fly the dauntless with a fuel engine or electrically.Both are included in the kit
  15. The electric retractable undercarriage with control electronics
  16. My magazine "Flug Modell" commissioned me to assemble and test the Dauntless from Phoenix.The model has a wingspan of 144cm and has a retractable undercarriage
  17. The undercarriage is ready for installation
  18. The wing and the tail unit are covered with Provicover 2 from Toni Clark. The fuselage as well.By the way, if you are interested, I can also describe the construction of the Dauntless, which has a wingspan of 144cm and is equipped with electric retractable landing gear.Off course, in an other thread
  19. Sorry for the long break, but I still had a Dauntless from Phönix to build and now I continue to build the M23.I wanted to reduce the weight of the wing and had installed a main spar made of very hard balsa. This saves a total of 120g and is still stable, but thanks for your advice. One wing now weighs 362g and that is a good value
  20. Now begins the construction of the wing.The main spars are made of solid plywood 13X6mm. One spar weighs 44g The same spar made of hard balsa weighs only 14g.This would be a weight reduction of 120g The main spar is moulded I therefore think that the surface has enough stability even with balsa spars. What is your opinion?
  21. Yes, I agree on all points.For me it is a challenge to build the model as light as possible without loss of stability.Unfortunately, I had ordered the complete kit from Sarik.So I replace all the heavy components where possible.Thanks for your comment. I already thought that no one was interested in my construction report.
