Topmodel Ka8 3m (1 min 8 sec)

About a year ago, I bought a second-hand Ka8 model in Germany. In a previous blog entry of mine I already stated my doubts whether it had really flown as the previous owner claims.
And so I removed about 200g of lead from the nose to get the CG right, struggled to get a towhook installed next to the motor, and I went about maidening this beautiful model.
Performance wasn't exactly what the previous owner described to me.
On 4S with a 13x6 prop, this thing should rocket skywards. But all it did was climb steadily at an acceptable rate.
And then, from the second flight on, a problem developed. Whenever I opened the throttle more than half, the model started howling with a sound that best can be described as a howling cow, or the horn of a freight train.
The loss of power was so sudden that the model stalled several times during initial climb.
I thought I found the culprit when I discovered that the motor firewall had come loose on one side, but after fixing that, the problem still persisted.
So, last week, I decided to dig into this problem, and did some research.
Apparently there are two versions of this model: 3m and 3m20 of span. And I have the 3m version, which has a recommended 35mm motor, with a 14x8 prop, on 3S.
But I got a 4S battery with this model! And so I measured the motor, and sure enough, it's a 35mm one....which I tried to operate on 4S. A miracle that this motor even survived this treatment.

And so I...Continue Reading

I recently picked up these 3 Cox Pt-19 airplanes + extra PT-19 fuselage/engine from a gym teacher who used to teach a class in control line flying at his school during the late 60s. He kept these planes for all these years and decided to pass them on as he was retiring/moving on. Before graciously accepting them, I asked if he had any young relatives he wanted to give them to instead but he said he didn't.

Included also were the cox manuals, extra control iine handles, cox wrenches, glow wires, and a wooden engine test stand. I removed each of the engines and took them apart to clean/unstick them and put them back together, and have found out that these engines have nice compression.

I feel pretty fortunate to have planes that were used to teach students to fly and I will like to keep them together as a group. The Cox PT-19s are supposed to be good flyers and these planes are in pretty nice conditon.

So my wife comes home from work with a new indoor flying toy. Skythunder flying drone a quad in a cage to go up and down walls doors . And yes a read very little charged it up and went flying not knowing a thing. So little hard for me to get battery's in but I did and off I went. Up and down the wall and door across the room you name it I did it. Got to say for indoor flight this thing is great and easy. Few more flights to get the hang of it can see this is going to be one of my top indoor toys and you can gets parts and the batterys comes out the toy.

It was the longest any vehicle ever went on a single battery. Set it to 6mph. Had the headlights off. Speed was somewhat variable because of the low accuracy of the inverter. Not sure driving the ESC using I2C would make the speed more accurate, since the bottom line is the number of bits in the 8khz waveform.

This achievement took 4Ah or 90% of the remaning capacity in the last full discharge. It would have a hard time going any farther or any faster. A fresh 5Ah battery would probably go 17 miles.

Here is my video 'review' / instructional guide on how to modify the 350QX for long range, quality FPV downlink.

The whole build is really easy to do once you know exactly how it works and you get a really powerful setup. It also resolves an issue with the 350QX GPS not having enough shielding with a noisy camera.

  • Convert your Blade 350 qx 1/2/3 into an FPV body.
  • You can integrate your OSD and A/V transmitter.
  • No more wires hanging. This is a very clean looking setup.
  • Carbon fiber canopy helps shield the GPS receiver from interference from cameras & adds space for electronics.
  • Carbon Fiber A/V transmitter compartment along with graphite RF shield blocks 90% outgoing RF increasing the range and quality of your video downlink.

Size of A/V transmitter compartment:

L 2.5" W 1"5/16 H 10/16" L 63mm W 33mm H 15.9
The A/V transmitter compartment can hold Boscam Ts832 600mw, Immersion RC 600mw, Fatshark 250mw transmitters and anything similar in size or smaller.

The canopy and A/V transmitter case along with graphite shield and antenna terminal can be purchased individually.

Package Includes:

1x carbon fiber canopy
1x carbon fiber A/V transmitter case
2x templates
1x external antenna terminal
1x graphite shield
1x installation guide

You can buy any of the pieces separately or all at once. The video guide I've created explains ALL of the hardware and exact setup based on his specs; however you are free to use whatever you like that will fit into the case! It's a pretty big case, and the carbon fiber canopy is a valuable addition all on its own.

Any comments or questions are welcome!

Just recently started back here on RCGroups and ,wanted to share my first ever hybrid build, utilizing some of the older parts from a few years back.

Having researched all i could back then and wanting to keep it as less costly as possible, this is what i came up with for the build.

Vitality H36 frame
Vitality H36 FCB (flysky protocol)
UDI U816 Motor boom and 7mm motors.
V997 mini pet props
V997 mini pet beatle canopy
Optional MJX 100 ufo canopy
UDI charger and 250mah batteries.

Just recently, after a long pause, i decided to finally assemble this little quad.

Here are some pics of the assembly..Total weight is with the udi battery installed...i don't have precision a precision scale so weight is not precise,... it weighs in at 33 grams with the mini pet canopy installed and trips the 34g mark with MJX canopy installed so, the 33 grams is on the higher end of the 33 gram scale.

The parts....Continue Reading

This video is the Unboxing Only for the new 2S E-flite UMX P-47 Thunderbolt WWII Warbird BNF Basic with AS3X Technology. This is essentially the UMX version of the the Republic P-47 Thunderbolt, parkflyer with different paint.

In the video I compare it to the parkflyer version of I mentioned above as well as the Parkzone UMX P-51, which was the first P-51 mustang with AS3X. The second and first park flyer with it was the E-flite P-51 Mustang, also know as the "Dallas Doll".

Here are my review notes on it so far:


- A big black mark on the nose of the plane fresh out of the box


- Beautiful finish and scale look
- 4-bladed prop
- 2S Brushless motor
_ AS3X Technology
- Large and durable looking landing gear

In the hardest test video, 2.9825% of the frames failed. Shadows are the hardest. Cloudy days are the easiest, even working quite well at 160x120. Higher resolution improved the results. 4k proved too slow to scan.

Normalization slightly degraded the results. Suspect the best results would come from manually setting the exposure, setting manually tweeked constants based on the exposure & path. The saturation is still manually set. However, it is about capturing the most information & the auto exposure is choosing the exposure that captures the most information.

The key computational user is the chroma key step, with any other step manely free. A different chroma key needs to be applied for each color of the path. Then, the threshold needs to be manually tweeked until the path has the right shape.

Tried dynamically detecting the optimum threshold by applying many thresholds to the same image & measuring the average distance of every mask pixel from the mean mask pixel. The optimum path shape should always have a similar average distance of mask pixels from the center mask pixel. This was slow indeed, but always produced very tight masks. The problem was the threshold converged on a constant value & didn't change in any frames. The return on the investment of clockcycles was minimal.

Also tried finding the thresholds where the total number of masked pixels jumped a certain amount due to a sudden bleeding. This didn't produce consistent...Continue Reading

hi everyone,im after information regarding z poxy finishing boat is nearly complete and I have varnished the hull...I am wondering if I can put a coat of epoxy resin over the varnish as a sort of extra covering and if so would I have to thin it down with something,,thanks mark....
