This video is for the new Losi 1/10 Scale Baja Rey 4WD RTR Desert Truck with AVC Technology. It shows clips of my buddy Odell ripping with it through through sandy dirt, jumping, and flipping.

Flying quadcopters is for everyone. The SJ X300 makes a great starter quad.

We are building an Impala MP326 from scratch. We will be documenting the build to show our progress.

Clint's father built and flew one of the worlds biggest rc MIG25 which can be seen on YouTube. We are going to use the same techniques, just to build a different aircraft 2.4m long and anyone is welcome to join in and offer some advice on building the Impala, but it won't be to absolute scale. It will be more of a sport scale.

Hopefully it will be easy enough to fly and later on we can use it as a
semi-scale trainer plane for those people interested in flying using a 7-8 kilo turbine.

That's about it for now.

It's rare for anything to work when transferred to the final assembly. In this case, the sound was still perfect, but thermal management was gone. The 5V regulator was pegged at 93C. It took a major rework to add a heatsink to it. It's adequate for normal apartment use. The regulators & STA540 stay in the 50C range. For 20Hz sine waves at high volume, fuggedaboutit. The 12V regulator instantly jumps to 100C & shuts down.

There were definite compromises for cost. It would have more power with a PC power supply, but need a lot of space. A 19V laptop brick with linear regulator was the most compact. A lot of wires & heatsinks are flapping in the breeze. It's unsuitable for a vehicle.

Adjusting treble is a buster. The probe points for R1, R2, R3, R4 are shown. R1, R2 determine the treble. They're both 40k when the pot is centered. R1 or R2 is 62k when the pot is fully deflected. The resistances can be calculated by applying parallel resistor equations to the Baxandall schematic.

Bass can be adjusted visually, but the bass pots turn in opposite directions. Probe points for bass resistors are R3, R4. The EQ could be broken out to a front panel extension, but it isn't changed often enough.

The 12V regulator is adjusted with R5 & its output is measured at the cap terminals. Voltage must not exceed 16V or the caps will explode.

The output of the DAC is attenuated with R6, R7 before going to the front panel volume control. The...Continue Reading

It's been a long time coming but I am officially done with quads. I love them, I push them beyond their limits and usually don't stop till I crash. Then it sits on my bench for a week or two before new parts arrive and I rebuild.

That was a good and fine until sine things changed. I recently had a little girl and I can no longer take the time/money to crash, fix, tune and fly. Planes are just as fun to me and the time from crash to flying is quite short. I may end up getting back into quads but for the foreseeable future, I'm done.

Lots done on the 'E. Irene' this past week!
I am using this build as a form of stress management. As odd as it may sound, I actually use it as a form of meditation.
What I mean is that I calm myself down and approach this build by mentally scaling my thoughts down as if I was actually in the same scale as the boat...(They're coming to take me away ho-ho! They're coming to take me away ho-ho, he-he, HA-HA!)

By doing this, it has allowed me to build in wonderful detail! So, please don't think of me as being a show-off. It's far from it!

Everybodys own boat, as shown in your own blogs are perfect! They are made personally by you and represent your own desires and joy of building this beautiful design! And...ALL of them...are the BEST BOATS out there! ...Continue Reading

The headless mode works great on this quad. The one key return...not so much.
what do you all think?

Hello... Just to share with you some thrust data:

Motor;
Turnigy D2836 - 950 Kv

Propeller:
Master Airscrew 9 x 6 and 9 x 4,
APC 9 x 6 and 9 x 4.5

Power source:
Constant at 11.1 V

Both Master Airscrew propellers were quite unbalanced, blades and hub. APC propellers were slightly unbalanced and the test shows they are more efficient.

NASA Spy Drone catches tropical storm turning into a hurricane. The surveillance drones, America’s largest, fly in the calmer altitudes of around 60,000 feet above the ground, where they can wait for over a day, cameras pointed down, watching. The same characteristics that make a Global Hawk a useful tool of war against insurgents also lend its power as a storm watcher. NASA has a Global Hawk, painted bright white and not Air Force gray--and last week it flew over a tropical storm Gaston, determining it was, in fact, a hurricane.

...To learn what you really like to do. Sounds pretty simple. But when you get into a new hobby, you are just feeling your way through. And you pretty much take what comes down the pike. Here's my story.

If you follow my chrono in the blog, you know I started off with a 3 Channel SuperCub. The goal was to see if I actually really could fly a model airplane. Quickly figured out I could. Even though, I had no club or instructors around to teach me. Guess I fell for the "teach yourself to fly" marketing hype. And with SAFE, I actually flew a model airplane. While I could fly, that didn't mean I was a pilot yet. And of course, there is that whole aileron thing...that I knew nothing about.

So the SportCub S came next. And I could fly that too. And the ailerons really were pretty easy to learn. And I forced myself to progress thru intermediate and into experienced mode. Still didn't consider myself a Pilot.

But these were basically trainers. They flew great, but pretty limited. I actually was able to do a loop, or two. And then some pretty ugly rolls, too. But that was about my limit to 3D tricks. Although, not without plenty of high speed crashes.

The funny thing is...for some reason, I wasn't all that into doing these few little tricks. I much more enjoyed watching the planes just fly around in scale patterns. And slow flight was what I found I liked better. And at low altitude. Just more relaxing and I thought if you fly lower to the...Continue Reading

Time to update my blog again! So I have been flying for 7 years now. Joined our local club. Have been the PR rep, the president, and now the vice president. I would definitely encourage anyone to join a club if possible as there are so many benefits when doing so. There is so much knowledge available from other members and someone always willing to help you out! It also opens your eyes to new possibilities. Since I have gotten in to this hobby I have met such amazing people- not only in person but online as well. Their generosity never ceases to amaze me. I have flown airplanes, edf jets, electric helis, quad copters and r/c cars. But I still enjoy flying planes the most! Especially off water. It combines 2 things I love, being at the lake and flying r/c. I'm definitely still addicted to this hobby, but since we bought a building across the street with a hobby store and a garage I no longer have a problem with where to store or aquire any more planes...Continue Reading

a video of some flying I did at a new spot we found just outside one of the local parks which was great for fpv but also had cows grazing in it, I wonder what they thought the quadcopter was?

All I have left now.....Garnet fuse and boom is not a garnet, it is a Viper from Top Sky, and is new.

Tail was partially rebuilt. If I remember right, I built the horizontal pretty much from scratch but the vertical I did small repair and mounted to the new boom. Need hinging.

Note holes for pushrods in boom. 4 new Kennedy composites pushrods from Blaster included.

Wing needed small repairs when I got it, which are finished. Now needs radio install and final covering. Covering is included. About 3 small tears need fixing.

Wing joints off center as you see, so wing mount is lifted on one side to get it true. All looks right.

Without pushrods, this weighs 7.65 oz.

So, mount servos, rods, RX, balance, hinge tail, a few pcs covering, balance and fly. Wing comes apart and horizontal comes off so you can pack up for travel or whatever.

Not sure on price, and shipping will have to be part of that.

I thought I could send photos. I'll just add to my "BLOG...Continue Reading
