I too managed to get out and after about 45 mins was on my own. I've been trying to take on board what the Flight Coach trace tells me I'm doing wrong! Of course, you do something else wrong as you fix one problem! However, I can see that my geometry I'm flying is improving - not on every flight I have to say! The Adverrun motor that I'm using in place of my late lamented TMCR does not have the level of braking when the throttle is closed and this is making landing easier to achieve. Two of the four landings I made today fell into the greaser category. Now need to make that 100%! Dreamer! The new Anthem has now accumulated 23 flights and trimming is almost there. I am still trying to find a nice compromise with the rudder while the vertical climb is almost hands off. Needs a gentle tweak on either down thrust or increased wing incidence.

This winter's build,Gangster 63
Peter Jenkins replied to jeff2wings's topic in Building from Traditional Kits and Plans
Just reading through your thread reminded me of how alike my Gangster 75 build was to yours. If you are interested, you'll find it here -
Only 10 made it to the start line at the second last UKF3A Aerobatic competition today at the Leicester MAC. The wind at ground level turned out to be very misleading as it was very gentle. Once you got airborne though, the full strength of a quite strong wind at 90 deg ish to the flight path had a few ending up in the next county! However, despite some interesting turbulence on approach there were no landing accidents. Today was my first competition flying my new Anthem, it's in the foreground of the photo. The aircraft is still part way through it's trimming journey so I'm hoping that finalising that issue and getting more practice with the aircraft - I'd only managed to notch up 13 flights before today - will help me to improve from my consistent position in the 5 competitions I've managed to fly in this year - last!

Got out fhis afternoon and zlthough there was a strkngish wind blowjng in mansged to fly 4 practices for tomorrow's competition. On the patch we tend to be shielded from the full force of the wind - see photo of the wind sock. However, as you can see from the model's position, the approach gets very close to that big tree and thar does cause a few problems!

Is that what we are missing in many of today's teachers of STEM subjects? -

Apparently, the Romans also bequeathed us the Railway Standard Gauge of 4 ft 8 1/2 inches. Used to the the size of the ruts in the roads that were made by Roman horse drawn chariots/wagons. Two horses arses wide apparently! -

Thanks Adrian. I have to say I was the tensest I've ever been on the maiden flight given the incidents that bedevilled my first Anthem. -

Two of us maidened our BJ Craft Anthems today. It's spooky seeing two identical aircraft sitting next to each other. Mine's the far one. Mark hadn't managed to cut the prop slots in his carbon spinner so flew without the spinners. In case you are wondering what happened to my first Anthem, I'd used the JR X-bus system to control the 3 servos in the tail i.e. 1 rudder and 2 elevator. On the 3rd flight of the day at my second and smaller flying site, as the Anthem came level with me it appeared to be having difficulty wanting to lift off. As the 4 ft high crop was getting closer by the minute, I applied full up elevator and the Anthem leapt off the ground and despite applying full down elevator there was no response from the elevator! It appeared to be stuck in full up! As the Anthem approached the top of a very low loop, it was clear there wasn't going to be a good ending. I closed the throttle and that responded but the aircraft impacted almost in the middle of the patch and was pretty much destroyed up to about 3 inches into the wings. Aft of that there didn't appear to be any damage at all! There was no response from either elevators or rudder but the motor clearly responded and the ailerons worked. After removing all the kit from the wreckage, I connected up all the components of the radio system and.......everything worked! So, I suppose the conclusion one could draw is that the X-Bus converter - it turns X-bus signal into PWM for non-X-Bus servos - must have suffered a glitch! My new Anthem has forsaken X-Bus and uses standard JR PWM control. Both maidens were uneventful. In my case, apart from needing a dose of down elevator, it was the same with the first Anthem, there was no need for either aileron or rudder trim - clearly the time spent in set up was worth it. There are a few more bits of trimming to do before the aircraft is ready for prime time. -
