Just happened to be chatting with a guy down the park about the small RC quadcopter i was flying and we got onto the subject of RC Trucks. Just so happens he had a Traaxis Stampede 4X4 gathering dust… Well it gathers dust no more. (just kicks it up in the air from those tyres!)
I’ve installed a temporary top plate* to mount the electronics to make this beast come alive. It fitted out with

I recently passed my Radio Amateur License Exam here in Canada. For my first radio I wanted something easily portable that I could take with me any where. I purchased a Yaesu VX8-DR handheld transceiver or HT for short.
The battery life of the standard pack (1100mAh 7.4V) and high capacity pack (1800mAh 7.4V) are commendable at about 4-6Hrs, well until you press the PTT and start chatting. At 5W power output, they get used up pretty quickly.
Another factor in this is that you cannot transmit while plugged in with the supplied charger. It just doesn’t put out enough current. So the what’s the answer? I have a cupboard full of RC LiPo at 11.1V and 14.8V nominal ranging from 2200mAh, 5200mAh and more. That should do the trick nicely.
NOTE: I should mention I haven’t tried the 4S (14,8V,16.8Vmax) batteries yet. VX8-DR specs say 12Vdc is ok. Car batteries are 13.8V when charging, so not sure if the regulator can take the higher voltage of the 4S.
I simply cut the cable of the supplied charger, and solder a XT60 connector inline. Now I can connect any of my RC LiPo batteries and save the power in the built-in battery packs when i need to go truly mobile. The RC batteries can also charge the internal battery, which is great. Maybe i need to enter some QRP contests 😉
The other benefit, as I live in a earthquake zone, that in an emergency, I should be able to run the radio for at least 72Hrs with no need of a recharge… awesome.
MAVPilot has been released to the App Store. This is a “Ground Control Station for your Pocket”. Its target audience is iPhone users. Pilots often fly unaccompanied and this can make it difficult to use a laptop at the same time. This is more so when a pilot is using a semi-auto mode like Alt-Hold. Using your iPhone instead is a great way to keep focused on the MAV and still have all the useful information in reach. With inbuilt text-to-speech support your iPhone will let you know instantly the status and if anything starts to go wrong.
The real progressive part though is that it achieves less typing, by using implicit types. For example
var myDoublePrecisionNumber = 0.007 # This will be implicitly define the type as double
var myExplicitPrecisionNumber : Double = 0.007 # This will explicitly define the type as double
If you would like to see my solutions to the ‘Experiments’ in a A Swift Tour you can find all the code in that section is the playground file stored in a gist on github
If you have a new Iris Quadcopter from 3DR with a FlySky RC Transmitter, you may want to add CH8 option to trigger other features. Below is a walk-through on how to add this to the standard Iris setup.
NOTE: This walk-through works by copying the settings that make CH7 work to CH8. This means you need a preconfigured FlySky from 3DR which is setup for Iris. I will do a later walk-through on how to do it generally for Er9X (OpenTx)
We are so close to the first lanch of MAVPILOT. I’ve been getting up early to do testing in the relative pace of the weekend mornings. As a way to get some exercise and so not to be just standing in a field for a couple of hours, I ride loaded. (I can also fit both kids on the back for those trips to the beach!)
MAVPilot is coming along great. Yesterday, I was testing some new features. One being audio alerts for when using using the fence as a safety feature. Now when you exceed the fence boundary you will get a warning as the craft engages Return to Launch or Land, depending on how you have set it. More info here and here on the ArduPilot.com site. The next feature for fence will be to outline the boundary on the map.
But before that we need to get v1.0 out.
(PS: if you have any killer features you must have, drop me a comment, or emaila. I’m always happy to receive feedback, thx)
