Hey Guys
Got a chance to stop by the NSRCA Booth, at the AMA EXPO show today, it was nice to meet up with Jon, Dale and a few others from Nor Cal, it was also pretty cool to speak with Andrew and Tim
Jesky,I also picked up a few nice items for the F3A team fund, Polo shirt, raffle ticket and stickers.

Hey guys, I got a up close look at the 3D hobby Osiris 2 meter patternship, man the thing is "HUGE", a very nice looking ship, an I would love to get one, but the one in the booth is part of the raffle
prizes, that will be given away, RTF just add radio.

Andrew, stated that it flies great. Also stop by Neu motors, they just released a new F3A out-runner motor, that can be firewall mounted or nose mounted, Neu also released a new charger.
Snapped a few photo's of Worlds Models, new 50cc gas pattern ship with a 86 inch wing span, hope to post more photos tomorrow.

any on the specs on the Neu??? looks nice and lightweight

Thanks for sharing Jarvis!

Hey Jarvis- How do we buy tickets for the 2M Osiris? And in case I don't win it , any word from Andrew on when it might be brought to market?

I will find out about the weight today, Andrew said that he does not know when 3d hobby will release it, it all about get the balsa wood, the whole plane is maked of contest grade
to keep the weight down.

Steve Neu is also adding a line of props. He has some RASA style folding prop designs that he is going to offer. Nice looking workmanship.

The large inrunner design is very interesting. It looks about the same size as the Pletty Advance. He didn't have any detailed specs on it but said it was similar in performance to the F3A-1 inrunner. The production model will be similar to the one at the show but will probably have more material around the front framework. It can be rear mounted or firewall mounted.

He also has the helical gear version of the P42 gearbox that is used on the F3A-1. It should be much quieter than the older gearbox.

I really liked the new charger he had. It can charge two 10s packs simultaneously, has the ability to charge at high C rates, has a neat user interface, can discharge packs, and looks to be well made. I just might have to find a way to get that one into my field box this year.....

Our 50cc Commander pattern plane is sold!

I was very impressed with the Jeti Duplex RC systems. The transmitters felt a little heavy but looked great. I thought of the line I had read about the iPhone being like a Rolex compared to a Timex when comparing it to other phones. The all metal gimbals use Hall effect transducers instead of pots so I would suspect they'd last forever. The system appears to have all the functionality we need along with an integrated Telemetry system that includes feedback on the signal strength at the receiver. I believe I would have saved a plane if I'd had this capability at the time. I'd sure like to get my hands on one of these systems and really explore its performance. Has anyone in the world out there got one and would care to share their experiences?

86" Pattern Plane?

I liked the gimbals on that transmitter as well. I asked what sort of transmission system it used and the guy said FHSS. He didn't have any more specific details, so I downloaded the manual so that I could get the FCC ID and go to the OET website and read the test report details. I only found a page that had a self declaration of conformance, no FCC ID. I'm not sure where that declaration would apply but it won't apply in the US. So, I'd still like to find the FCC ID on this and review the test details. They must have one, otherwise it would be illegal to sell in the US.

Hey Jim
I also took a look at the radio, very nice, if you contact Peter,he picked up one, $1500 dollar, sounds like a lot of money,18MZ $3000.
I tried today, to get spec, on the Neu out runner, but Steve was not there.

Great AMA EXPO

Steve, I got the impression that they didn't have the type acceptance on the $1500 version but they did on the $1300 version. The difference being the more expensive one had a gyro/accelerometer that allowed one to send commands by tipping the transmitter. At first I thought this was crazy but then I thought about all the times I wished I had another hand.

Jarvis, which Peter?

Jim, it was Peter Vogel from Nor Cal

Not legal for F3A, but several companies over the last few years have come out with 50cc size pattern planes. A little larger plane that flies well. I know there was a discussion of a 50cc class a few years ago, but nothing ever materialized to my knowledge.

Arch

There is a company here in the states (name escapes me at the moment) that has at least one classic pattern planeenlarged to50cc size (wood kit). The wing area is small at 1200 but the effort may be worthwhile for some. I have the kit but plan on a modified, larger version to handle today's 50cc piped power

$1295 actually, with 9 channel RX. It's the DC-16, 16 channels, full FCC cert sticker on the back (I believe the DS-16 is still waiting on FCC) tray style radio, I'm excited to try it out on my Griffin, from reading the manual and doing some initial playing, it's very intuitive to program and a much more "robust" feeling radio than my Spektrum DX-10t.

The only downside is now I don't have the simple redundant power receivers from Spektrum so I need to figure out a clean lightweight redundant high voltage system. I'm thinking thunder power 3s receiver pack going to a CC BEC programmed for 7.9v with the Mezon ESC providing an 8.0 volt output from the main battery, those two providing the inputs to a Fromeco Wolverine switch or a Smart-Fly Batshare that way I get a nice consistent 8.0-7.9 volts for the whole flight. Jim O, what do you think?

Found the FCC report for the DC-16. Here's the key info from the cover letter: "ONTJETIDC16US consists of two transceiver boards which are configured to hop continuously and sequentially among 15 non-overlapping channels in the frequency range 2405 MHz to 2475 MHz using a Jeti proprietary application based on the 802.15.4 platform."

That translates to the system being a hybrid, similar to Futaba, which is a Frequency Hopping Direct Sequence Spread Spectrum system. It is specifically adapted from the industry standard Zigbee protocol.

BTW: That's a good thing!

Just got the word from Neu motors that the "new" F3A motor that was in their booth is a large diameter inrunner like the Plettenberg Advance 30-10. More details and pricing to be released in a month.

Crap. I just got a Pletty and now there is a new Neu too??

Is there no end to it??

Inrunner? Looks like it is outrunner.

No. Notice the stator windings and the input leads are on the outside and the magnets are on the inside on the rotor shaft.

Regarding the DC-16, I had a chance to run it through the programming paces last night and today WOW.

16 free mixes (though there are no "standard" mixes like rudder/elevator or flap/elevator, etc. so any mix you need will use a free mix (except standard control configs like ailevator, butterfly, swash, etc.), incredibly versatile control surface preset options (1-4 aileron servos, 1-2 elevator servos, 1-2 rudder servos, 1-4 flap servos) my only complaint is the 2 elevator/1 rudder tail option is treated as "Ailevators" which defaults to setting the elevators up to induce roll when you do ailerons, but that's easy to turn off in the "Ailevator" settings, just don't forget! But beyond the presets, you can set up any number of receiver channels to take their commands from any input control, proportional or switch. Each independent channel can of course be subtrimmed, reversed, travel adjusted in either or both directions, etc. Mixes can be chained so that the output of one mix is the input of another, you can also choose to have a mix influenced by dual rates + expo or not so its based on stick position or on output values.

10 fully programmable timers that can be free running, start/pause, or lap and count down or up, activated by any switch, including stick position switches on any proportional channel. Feedback from the timer can be beeps, voice, or just displayed or even just tracked. You can even set up which timers are cleared when you turn the radio on and off.

telemetry is built in to the Mezon ESCs and the receivers, you always get telemetry of the individual receiver antenna performance and the RX battery state (and, with a Mezon ESC the current consumed + pack voltage) but other stuff is optional and typically has to go through the telemetry input expander unit. There's a very cool app for a PC that will read the telemetry log (see below for the unique way the TX interfaces with a PC) and play it back for you over time, if you have GPS telemetry it will show the whole track of your plane (in 2D) over google maps (any display option).

The TX presents to a PC (or MAC!) as an external storage device over a standard USB cable, with a very intuitive directory structure making it trivial to archive models on your PC, pull telemetry logs, transfer audio files (.wav only) for custom alarms or even a pre-recorded sequence caller to prompt you as you are learning a new sequence :-) SW updates are as simple as copying the contents of a zip file into the root of the transmitter "drive" (using your PC or MAC) and then turning the TX off and back on.

The TX is fully capable of acting as a Jetibox to program receivers, ESCs, etc.

Very easy to adjust stick length, any switch can be moved or swapped out (i.e. if you want fewer or more 3 position switches or spring loaded switch). A total of 8 proportional controls (the usual 4 on the sticks in any mode configuration with two side sliders (L + R) and two knobs (L+R)). The back comes off very cleanly by removing 10 machine screws giving you full access to everything in the back for moving stuff around, swapping switches, or changing stick tension, smooth + ratchet tension on the throttle stick, not to mention swapping out the 3200mAh lipo if you like.

Any number of logical switches can be programmed to turn conditions on/off based on physical or logical control positions.

At least 16 flight modes can be programmed and named, to be activated by any number of switches that might be needed. Transition from mode to mode can be arbitrarily delayed.

Very flexible control curves with 3, 4, 5, 7, or 9 points which can be placed arbitrarily on the X + Y plane.

Many settings can be set up as global or per-flight mode, with the transition from global to per-mode resulting in the global setting getting copied to all mode settings as the starting point for tweaking per-mode.

You can set up throttle cut and throttle idle switches to move the throttle to a specific position (i.e. -125%) for cut and to apply a specific offset to the throttle (pos or neg) which seems like a very natural way to disable the brake by maintaining a slow idle on an electric and enable it at will by flipping a switch.

My head is still spinning a bit, but I was able to set up my griffin in under 30 minutes, almost as quick and easy as on my DX10t and the time difference was just a matter of familiarity.

They've found a clever way around the model match patent (which relies on the RX seeing a GUID from the TX and only listening to that GUID) in this case the RX sends its serial number to the TX when you bind (since communication between TX and RX is bi-directional) and if the TX doesn't see the serial number for the RX(s) that were bound for the model memory it won't transmit, so you do get model match functionality.

Once I get the griffin ready to fly, etc. I'll post a video of setting it up from scratch in the radio and do a flying review in a separate thread.

Peter+

Very cool!

Peter, I've been watching the videos and reading the manual and it is looking good. I couldn't imagine how one might use the tipping of the transmitter to activate something but in the video they had it programmed to tell you the remaining time in your flight. I assume you could tip it the other way and get the remaining battery capacity. Neat stuff. It wasn't clear if you could daisy chain the logic, but I assume you can?

It is supposed to be a 4096 (12 bit) system. I wonder if you can see it at the servo?

It doesn't look like the receiver is included in the prices on their web site. Was that a show special or just good negotiating?
