Lipos have been hard to find for over 2 years now. My experience was the best ones were Turnigy graphene, but when these were unobtainable I moved to Dualsky and also tried other brands. Zeee lipos are sold from a Sydney location and arrive within a few days of ordering. So far I have purchased 2 Zeee 1300 mah graphene lipos rated 120C for a very low price, to my surprise they are the best 1300 mah lipos I use (I have flown around 8 sessions with them). They produce higher sustained power than the competition and do not have voltage sag. Dualsky lipos are generally disappointing but Dualsky 1300 mah are an exception, they are good however they are quite not as good as the Zeee.

My Edge 3d plane has a single band R9 900mhz rx, that I use with a frsky tandem tx. It has a 3S lipo. Measurements were taken at 0.5 sec intervals, and with frsky logging the RSSI is a percentage.

At 207 sec the valid frame rate fell to 64%, one measurement only, with a level below 70 considered an incident. The RSSI remained above 70%. I looked for any anomaly in the power supply. With frsky logging you can simultaneously monitor 3 lipo cells. At 207 sec there is nothing happening, the rx voltage remains at 5.0v for the entire flight, and the lipo cells are all together, in the expected range.

I conclude there is no problem here, the R9 rx has been without a glitch for many months, and others have found R9 rxs, either ACCST or ACCESS,  work great at PRCAC.

I want to log the rx voltage on my planes with elrs rxs, but so far I can only monitor either the lipo voltage, or the rx voltage, but not both. I use the lipo voltage for deciding when to land, and am reluctant to give it up. So I need to find a way to monitor lipo and rx voltage simultaneously, and I do not want to add a flight controller to achieve this.

In light of the RF signal issues some people have reported at McCoy field, I had a look at the telemetry logs of my last couple of flights there.

I'm using ELRS at the 100Hz packet rate, using 10mW transmitter power (this is the lowest TX power setting on my internal ELRS module on my TX16S transmitter)

ExpressLRS recommends a minimum signal sensitivity limit of -108dBm for 100Hz.

In my flights there (including flying at the same time as Stephen with his ELRS system) my telemetry reported RSSI level (1RSS, as I have a single antenna ELRS receiver) never got below -85dBm. This is the RSSI level reported by the receiver. I also log TRSS, which is the telemetry RSSI reported by the transmitter, but it's also not anywhere close to the minimum.

The other measured value i looked at was LQI - Link Quality Indicator) which represents the proportion of messages cleanly received. This got down to a minimum of 94% on one flight, but generally was in the 97-100% range. At 100Hz packet rate, a packet or two missing every now and then is not an issue.

   

Long story short: In my experience, ELRS appears to be unaffected by any interference or link quality issues at McCoy park.

I'm using Aerofly RC7 as my simulator-of-choice. It is a bit old but it runs well and looks good on my not-a-gaming-PC and works with my TX16S using a USB cable.

What does everyone else use?

I note also that Aerofly offers a multiplayer mode, so if anyone else has it and wants to fly around at stupid-o'clock, let me know!

I'm looking for inspiration as to the best way to safely store planes. I have a handful of foamies up to 1.5m wingspan, and some balsa/film ones bigger than that (up to a 2m bird of time glider as pictured)

At the moment they're precariously stacked on shelves or leaning against walls, and they're in the way and consequently in danger of getting damaged or knocked over.

I've considered shelving in the garage, but it's pretty dusty in there so I'd need to make covers, and in summer it can get over 50° in there so I'm also concerned about heat damage.

I've seen some instances where people hang planes on the wall. What's the best way of doing that in a non-destructive way?  (to the wall and to the plane)

Any ideas? I want more planes but I'm held back by storage at the moment.

I've been doing a bit of poking around on AliExpress, to see what sort of RC stuff is on there (answer - pretty much anything)

As a 'toe in the water' exercise I ordered 10 4-pin (suitable for 3S batteries) JST-XH balance connectors (male PCB mount and female connectors on wire) for the princely sum of $0.02 (plus $0.28 GST) shipped to my door. They arrived in 1 week and were exactly as ordered. It was some introductory special, normal cost was ~$3.00 shipped.

Buoyed by my experience, I went and did a bigger order; 10 9-gram metal geared servos for $25, a 30A ESC for $4.77, 10 5mm x 3.1mm x 500mm carbon tubes for $23, an absurd quantity of control horns and hinges for cents, 30 3.5mm bullet connectors for a few dollars, 10 shrouded XT60 connectors for a few dollars, 20 JST-XH male wire mounted connectors for $7 and 10 spare IPEX 2.4G antennas for my receivers for a few dollars.

These all arrived today (2 weeks after shipping) and everything is as expected except the JST-XH connectors; they sent me female ones instead of male ones. I disputed it with AliExpress, attached 1 photograph and 2 hours later had a 50% refund, which is satisfactory for me.

I'm pretty pleased with how it turned out. For cheap planes like my foam KMart glider conversion it's excellent. I'll certainly keep ordering receivers and batteries from local reputable suppliers, and for my more serious planes I'll stick to name brand stuff, but for consumables and cheap foamies it's perfect.

I've tested all the servos and the ESC and they work perfectly. I'll embark on my next foamie conversion with the parts soon (a flat wing kmart glider with 1900kV motor, full span ailerons, elevator and rudder, should be more dynamic than my first one  )

Hi all,
I know I’ve been asking about a FRSky for a few weeks though learnt today my father in law was about to press buy on this transmitter. I’ve explained there are a few here that may provide valuable feedback so just reaching out if anyone has feedback on this model?
He is currently using an older as well Digi6 Specktrum
. Like me, hence I’m interested too.
Any guidance would be appreciated and just posting here as wrongly posted in For Sale

Hi all,

Been looking for one of these flying sticks for some time and note a few in the club have them. I was keen to build one though between work and family finding hard to find the time.

Should anyone look to sell theirs in the future please can you let me know as very interested.

Thank you

The radiomaster (RM) boxer is the standout tx, even amongst txs costing hundreds of dollars more. Costing a bit more is RM Tx16S which has a color touch screen, and costing considerably less the RM tx12. I own a tx12 which is an excellent tx, initially it felt a bit small but now I am used to it I appreciate its low weight. The edgetx software that comes with RM is better than Opentx, and I also think its better than the new Frsky ethos. My opinion is RM gear is high quality, and the txs I mentioned have been highly praised in online reviews.
The question whether you should select an internal module, 4in1 or ELRS is discussed here:

https://www.rcgroups.com/forums/showthre...st50862537  post #340

Its hard to find a dealer with a boxer in stock, but new shipments are arriving. If you buy a RM and are a mode 1 flyer, you have to convert from mode 2 which is a pain.

If you choose elrs internal module, you can add a 4in1 external module and have both frsky and elrs available. For elrs, there are 2 PWM receivers - normal airplane rxs - (one radiomaster, the other betafpv) that come ready to fly, for other PWM elrs rxs you have to solder the PWM pins in place yourself or use a microsoldering service.
The 4 in 1 internal  module, or external module, allows you to use your existing ACCST frsky rxs. But I think its better to use the opportunity to switch to ELRS, as I am doing (I am testing several systems for a year including Frsky Tandem and R9 before making a final decision on elrs, after 4 months elrs is looking good). Be warned you have to learn to use new software and new procedures with elrs, it took me about a month before I was comfortable with these.
