So today marks one year of me in this amazing hobby, and I thought I'd give something back to everyone.
I have some FPV goggles to give away, as well as a KingKong Tiny 6 and some custom battery straps!

See here for the details:

excerpt found on a forum

" A chapter of Trout Unlimited is proposing legislation limiting use of streams stocked with trout to fishing only. Boat traffic including canoes and kayaks will be prohibited along with any motorized vessel including radio control boats. Soft vessels such as rafts and tubes would be allowed, This move is to limit damage to breeding areas of insects that feed the trout."

As some may know im rebuilding my madgear rc SCT which was my first RC i got this truck in june 2015 and im now doing some hopups which i plan to buy a brushless kit new wheels new gears and stuff
The reason for this build i that either the ESC motor Or Reciever broke and now it wont run and wont connect to the transmitter so its most likely a motor and a reciever/Transmitter problem which ill fix when i get a brushless esc and a new reciever.

The worst thing about it is the motor where i have to hold a wheel on thats unbolted spin it hard and get it to move but even after that the wheels only spin for 30 seconds then it stops so thats a problem.

The purpose of this rebuild is to bring my first rc back to life and working again with more power.

All of the problems i have found so far are
1.Broken motor that takes a jumpstart to work
2.Broken reciever/ESC that cant pick up my controller which causes my transmitter to beep really fast before it stops because i cant figure out how to bind it
3.Bad gears. The plastic gears that came on it have never been taken out or replaced with better gears and the spur is missing a few teeth and the pinion is in pretty bad shape as i can see black plastic from the gears around it.
4.Most likely a broken transmitter because it beeps alot when i turn it on and the car on therefore i think its broken and ill probably get a new one if possible that works with my new esc and reciever hopefully i cn find one that will connect.
5.No...Continue Reading

The closest you'll get to a vintage computer might be the FT2232. It's 1 of the older FTDI chips, but apparently still in production, widely available, & quite capable. It's a dual serial interface. The high end is the FT4xxx line which are quad serial interfaces.

The trick with the FT2232 is to not use the commercial drivers, but use libftdi. Most of the commercial drivers don't support it but libftdi does. Also, libmpsse provides limited abstraction of libftdi into SPI, I2C, & GPIO interfaces, but it doesn't allow simultaneous GPIO control & hardware protocols which the FT2232 does allow & it has many bugs. The trick is to refer to libmpsse to get the command structure for the hardware protocols, but directly call libftdi commands in your own program to control the GPIOs.

It's not clear how he figured out the command structure besides sniffing packets as they went through libusb. FTDI doesn't document it anywhere. Fortunately, it's not a very complicated protocol. The chip doesn't have any concept of GPIO, SPI, I2C modes the way libmpsse does. Libmpsse just uses mode settings to determine what commands to send, but the chip can accept any command in any mode.

The hardest part is figuring out the pins labeled GPIOH & GPIOL are ambiguous. What's really happening is all the pins labeled ADBUS are GPIOs written in a traditional 8 bit GPIO register & all the pins labeled ACBUS are written in another 8 bit register. They can be...Continue Reading

4.13.17.... I made it to the field for 4 more Sensei flights. I used the DX6 voice alerts with the timer. Nice feature. I didn't mention the wind on the previous 4 flights, those flights being the first with the DX6. The Sensei was out of trim and it was windy.!! 3 of the 4 flights today were spent getting the plane trimmed out. It needed mechanical trim and the 3 flights were pretty sketchy. Finally the 4th flight was smooth and enjoyable. It's a great plane but it's showing some hangar rash and the batteries don't seem to have the punch that they had a year ago. Something to keep an eye on. my next trip to the field I will bring along the Freewing Texan. That will get me in shape to maiden the LT-25 that I built over the winter. So, 8 flights on the Sensei to begin the 2017 flying season. Fly on....

Fsecondnday flying the hobbyzone Cub s with the accelerometers and safe system.

My son is 3 and it is awesome to use wireless buddy boxing and the SAFE system to let him fly.

Hi, everyone. I am going to purchase the losi 8ight 4.0 and have a few questions.

1. servo recommendations for throttle and steering.

2. What is a coreless servo?

3. is the dynamite .28 rtr engine from horizon hobby a good choice?

4. How do I know what voltage my servo is getting.

5. recommendations for exhaust pipe.

I have been trying to get to grips with a blade sr120 and I am not a pro but I have been flying mcx, and mcx2 for ages with no problems, but I can't even get the Sr to stay up ⬆ have tried all ways and it just goes everywhere else, now is this my awful skills or have I got a faulty product because I have had nothing but good reviews on this model and I am not convinced that it is????

An auto-switching aileron-to-rudder mix for the Taranis
For OpenTX version 2.1.9

Aileron-to-rudder mix is useful but there are times when you want rudder control to be completely separated from aileron control. A common solution is to turn the mix on and off with a switch, but here I'll describe a setup that does the switching automatically. It works like this:
  1. When the aileron stick is moved away from center while the rudder stick is centered, aileron-to-rudder mix is active.
  2. If at any time the rudder stick is moved away from center, the mix is automatically cancelled and the rudder stick takes full control of the rudder. The changeover is slowed slightly for a smooth transition.
  3. When the rudder stick and aileron stick are both centered, the mix is reactivated.
In other words, the rudder is controlled by one stick or the other but never both, and the rudder stick has priority.

A simplified eepe file is attached that demonstrates the setup, and if you have glidsim.lua installed in your /SCRIPTS/TELEMETRY folder you'll be able to watch it work. Activate the glidsim screen with the PAGE button. In Companion simulator, use the [Hold X] function to set the aileron stick away from center, then move the rudder stick and watch what happens.

Note: Of course the attached eepe file is not meant to fly a real model. It's only for demonstration purposes.

In this example, GV1 is used to set the amount of aileron-to-rudder mix. The value should be between 0% and 100%. I have it set to...Continue Reading

I originally built the SCX 200 a few months back, and really liked it a lot. Just recently when Akk Tek contacted me and asked to review some of their equipment. I thought about just swapping their camera out with the ones already installed on my SCX 200. But then I had a better idea! Why not just build a new SCX 180!

On my original SCX 200 build I did things a little bit differently from this time with the SCX 180. A lot of the on board equipment is different too. The last time I only used one LC filter on the VTX. This time I used two LC filters. One on the VTX and one for the camera. You can really see a difference between the two builds as far as video feed go. As far as I can tell, this early on, this Akk Tek gear going in my SCX 180 is absolutely on par with the gear I used in my older SCX 200 build. It's also a bit cheaper, which is a major plus. Now that I know the 2nd LC filter made this much of a difference, I'm sure once I get another one installed on the camera of my SCX 200. It will probably look just as nice and clear. But for now, it has significantly more horizontal line noise than my SCX 180 with two LC filters and the Akk Tek camera, VTX and antenna .


Here is the short overview video of my SCX 200 build and maiden flight:

Now here is a more detailed build video for the SCX 180, which is pretty much the same frame as the SCX 200 but with shorter arms.

I kept crashing in all my heats. Out of the 19 packs I burned last night, I flew my first complete crashless heat on my 16th pack. Below is a video from one of the heats. Still working on tuning. Slowly understanding each adjustment and making changes here and there. Next up is tuning out the shakes
