Amazing super-wide angle lens with no 'fisheye' distortion. This lens is light weight at 6g and super sharp with 16MP optics. Special optics make this lens 'rectilinear' so there is no fisheye distortion at all. Excellent edge to edge sharpness. Perfect for drone and gimbal use and great for general shooting.

Now at issue is the failure of the gimbals to return to zero ..
And the fault lies entirely with the little sensor pots that fit the gimbals assembly .
In effect they are a poor / or slop fit . ( See first picture )
In a nutshell ! > The cure is to gently crush the shaft that enters the gimbals tube till its a press fit .. ( Crush the widest part , )

The 2nd thing to do is tape the outside of the sensor pot ( See 2nd picture ) to take out the slop @ the outside of the pot ..
Tape both sides ..

Tricky bit is obviously pulling the gimbals apart .

Its all relatively easy till you get to the last sensor .. The gimbals housing has a cover ...
Look for the release tabs .. Turn the gimbals assembly so the stick is down .. Gently press the stick against something and then release the tabs ( push in ) .
With the cover off you can remove the last sensor ......Continue Reading

SCX10 R/C Mud Truck Makes A Splash (2 min 33 sec)

The CCxRC Snakebite custom SCX10 R/C Mud Truck makes its first splash. My boys and I spent the past week digging a mud pit course in the backyard and keeping it soaked and soupy (yes...my wife is amazing). The 3S Venom Power to the brushless system in this truck was way more than enough to power through the sticky mud that had trapped my boys' boots moments earlier. .

Got some help driving from my 8-year-old son, Dino. He's the one who helped me build the custom truck. It was a fun bonding moment between the two of us.

Hope you enjoy the video.

Watch the longer version that explains more about the truck:

No real change...still a couple functions that do not work well.

Overall a nice stable foldable quad, great for beginners.

I also added a new charge lead to the battery so I could charge with an alternative charger. Now I can get max flight time with a peaked battery.

As an Engineer, I am probably going way overboard (pun intended) with my design and documentation. However, this is part of my paying job, so it is second nature to me to do so.

Therefore, let us begin:


This report is to document the design and construction of a 1:12 scale model of the US NAVY Torpedo Patrol Boat PT-615. Since no commercially available parts are available for a model of this scale and design, I have engineered and produced all of the boat specific parts and components. Some components such as electric motors, batteries, lights, bearings, couplers, and hardware are purchased parts.


The design concept of this model was to create a 1:12 scale remotely controlled, accurately detailed model of a US NAVY 1945 PT103 series ELCO (Note 1) 80 Ft. Torpedo Patrol Boat. PT-615 was chosen as the prototype . Although PT-615 was not deployed during WWII, it was completed and put into active duty before the end of the war. It represents the last configuration of the ELCO 80’ PT-boat design. Note that the last boat completed by ELCO was PT-624 as the war had ended and the contract for PT’s from ELCO was cancelled.

As designed, the PT103 Series 80’ boats were equipped with Packard Marine engines of increasing horsepower, the first boats having engines with 1200 hp rating and the later boats 1500 hp each. The majority of the boats were equipped with the center engine having direct drive, and the two wing...Continue Reading

Banggood sent me this VTX for reveiw. It was ordered January10, 2018, shipped on January 11, 2018, and arrived on January 24, 2018. Decent shipping time. The box was only slightly damaged, no damage to the contents.

First Impressions

It comes in a nice little box with an antenna and wires for hooking it up protcted by white foam insert. The VTX has clear heat shrink around it. There is an LED display on the bottom and it has one button. The wire plugs are different from any I have used and would not plug into any camera I am using, in this case I used the Caddx Turbo Micro F1. I had to cut all of the wires and resolder them to different plugs. I was replacing the EWRF e708TM3 5.8G 48CH 25mW/200mW/600mW, and the plug for the VTXs are also different. It would be nice if all one had to do was unplug one VTX and plug in the other, but that would mean standardizing the plugs on VTXs. The VTX alone weighs about 8 grams, so with wires and the pagoda antenna I am using it probably added around 20 grams to the the quad. The ad on Banggood lists the measurements as 31 x 21 x 5 mm, but I measured it at 32.0 x 22.5 x 8.0 mm.

Just got word that my son can join the RC Club & AMA free if I join & sponsor him as a member.
He has had several really good beginner quad flights without incident. So I'm proud & excited.
I'm about to offer him the parts to build his own quad. I want him to learn the satisfaction you get from learning new skills & completing your own creation.

For the past 8 years I have wanted to learn to fly RC planes. 6 years ago I bought a Phoenix Simulator and tried to learn to fly RC helicopters, which proved to very difficult.

In September 2017 I attended a local RC airshow and rekindled the urge to learn.

I'm close to buying a UMX Radian to finally get the learning process underway.

2nd plane: eFlite Valiant 1.3
