After the prototype second flight, we had to stop the plane since the motor had lost 4 magnets (well, they just detached from the bell and moved a bit actually). Although the motor itself was repaired the next afternoon, we decided to try a different engine, and ordered a Turnigy 3548 sk3 motor. Honestly I can’t blame completely the original motor. It was running to the max power rating, and even if the first flights
The big moment has arrived for the Juliet2 We are finally going to fly it As all the family was there for the event the first accomplishment of the day has been for sure squeezing two adults a baby car seat a golden retriever and two planes plus equipment in a sedan
With the Tundra and the Juliet in flying order, I enjoyed the first part of the season at the field having fun. Still, I managed to make some progress to the A1-D. We can now say it’s reaching the final steps of the construction. Having the model structurally complete, I made some tests to see where I could expect the CG to fall. While of course not 100% accurate at this stage, the results brought
Dopo aver tagliato e provato tutte le parti diverse volte a secco, è giunto il momento di iniziare la costruzione dell’A1-D. E’ molto importante, con una struttura di questo tipo, trovare l’ordine di assemblaggio corretto e attenercisi. Ci sono molti incastri che devono allinearsi e alcune parti, semplicemente, non possono esser messe in posizione dopo di altre. La costruzione dell’ A1-D Per questo c’è voluto un po’ di tempo per arrivare alla fase della costruzione
L’ A1-D Juliet II era andato avanti lentamente durante la stagione 2018. Ma con l’arrivo dell’autunno, sono iniziati i lavori veri e propri. Finalmente abbiamo iniziato a vedere qualcosa prendere forma davanti ai nostri occhi. E velocemente anche. Dagli schermi al tavolo da lavoro E’ sorprendente quanto l’uso di un programma di modellazione 3D possa rendere facile la fase di costruzione. Prima di tutto, ho potuto vedere il modello da ogni prospettiva e migliorarne la
While rebuilding the Juliet, I had plenty of ideas on how the structure could have been improved, lightened and made easier to “operate”. Since the ideas kept piling up after the first flights, some of them found a way into the model after our first little crash. Of course they were limited to small design corrections. We just put all the rest in a drawer for later use. In the meantime, we were already looking
Previous Next Thanks to our new testbed for carbon fiber and balsa sandwiches (more on that on the Juliet2 page), I was able to start a partial redesign of the C18. The use of composites helps to beef up the most stressed points. But the most important aspect, it does that without adding complexity or volume to the structure. At the moment we are focusing our attentions on the important area of the mid fuselage
After what has been an unexpeted series of successful flights, it eventually came the day on which I dared a bit too much a bit too low. Coming out from a series of hoverings, I messed up the recovery and impacted the ground almost vertically. It was only from a couple of meters of height, but it was high enough to hurt. Surprisingly the damage was not extensive. To be honest, the plane could have
One of the reasons why I decided to come back to the hobby, was to try out FPV (First Person View) flying. With the A1-C getting close to its first flight, I started to think of a plane to properly experiment with flying through a camera (or more than one), but not only that. By far the biggest limit I had was space, for storage, for transport to the field in the cabrio, for eventually
