I finally got my hands on an E-flite UMX PT-17... What a great little ultra micro, I can't wait to fly it. It's too bad that it doesn't come with a pilot, but I did have a spare micro pilot laying around from a Flyzone Tiger Moth. So I painted him tonight and should make a good fit for the PT-17, he seems to be quite close to the right scale.
Here is some project that I have recently started : a video diversity system, *without RSSI*.
This this system monitors and compares the video quality of the composite video signals, and switches to the best one. Of course the idea is not new: see for instance the Oracle diversity or the Eagletree ground-station. But the present one is meant to be DIY.
Compared to the popular RSSI-based systems, the advantages a video-based diversity are :
- No need to open the receivers to get the RSSI [Receiver Signal Strength indication] signals. You just have to plug in your different receivers, and they can be of different types.
- There is no need to calibrate the RSSi signals of the different receivers (this is often the tricky part).
- It is also frequent to get a strongly distorted image, while the RSSI is high.
- When the reception level is low (flying far for instance), some receivers have RSSI close to zero, although the image is still viewable. In that case an RSSI-based system is not really efficient.
So far I only tested the system on the bench (video soon...). I just made some basic indoor tests with 3 receivers in the 0.9G band, and it seems to pick
the best image reasonably well. Of course I still have to test it in real conditions.
A few comments on the hardware:
- Cheap (<20$)
- Some LM1881 chips are used to extract the (horizontal) sync. information from the composite video signal, as in Oracle's system.

Operating Current: 210mA maximum (both RF module and backlit are on)
Operating Temperature: -10~45℃
Backlight LCD Screen: 128*64 outdoor readable LCD
Model Memories: 60 (extendable by SD card)
Compatibility: FrSky X series, D series and V8-II series receivers (plus other receivers if an external module is used)
Quad Ball Bearing Gimbals
Audio Speech Outputs (values, alarms, settings, etc.)
Antenna Status Detection and adjustment
Real-time Flight Data Logging
Receiver Signal Strength Indicator (RSSI) Alerts
Super Low Latency
Smart Port Supported
Model configuration files compatible with TARANIS X9D Plus
Built my son his first jet. It is the little skymaster/extreme cougar. Fantastic little plane. We powered it with a Kingtech K45. It could use a little more engine but this engine is great for learning how to fly scale and not be overpowered. The maiden went well and its a very easy plane to build. It took about 2 weeks to have her ready to go of just casual work.
Short video of my son flying. I dropped my phone near the end lol so I missed the end of the flight.

Here's a bunch of pics from a great event. We met some super nice folks and enjoyed two days of fun in the wind and rain.....the group was focused on fun, regardless. Looking forward to next year's event. ...Continue Reading
Need help please I'm new to RC cars have a team Orion duo charger and I'm charging a 1800 7.2v battery it shows charging but the voltage says 9.32 and mAh is at 993 just need to know am I overcharging battery.
Eachine E010S flips over anytime I try to fly.
It is not consistent which direction it flips, but usually rolls Left.
It was successfully bound with Taranis X9D, and is running Cleanflight,"SPRACINGF3 1.13.0 Jun 6 2016 / 00:03:10 (a77bc76)"
All the controller channels show up in the correct places on the receiver tab of cleanflight.
I am a noob, but the only anomaly I see, is that the accelerometer seems to be drifting. (After calibration, the model is stationary, but the simulation in cleanflight moves around slightly.
I am wondering about the best place to ask of help with this, prior to contacting Banggood for support.
