Video of the Flite Streak......a bit of Dutch Roll and porpoising....... need to make the couple longer, and probably add an inch or so to the nose as well....she's touchy.......this flight was all on low rates (< 50% throws and > 50% Expo)...but she's fun to fly

Hey, so last night I was testing a string of LED bulbs, nothing too crazy, forty watts' worth, to see about how long two 1600mAh packs in parallel would keep them lit burning 40W. My nicest 1600s. Why? Never mind why. Then I'm screwing around on the laptop, up to no good, time passes, and it hits me, the LEDS are dim, oh no!, I let it run too long, packs' are probably dead! Should have used the damn power supply and a wattmeter...

Maybe you've figured out what makes you happy and are already equipped for it, but in my case, the amps and watts I need in DC from an AC source is a function of time, and for others like me, I'd say it's handy to have at least one high current AC/DC power supply. And not just for powering your chargers: If you experiment in your hangar "on the bench" with a wattmeter/thrust stand/RPM/temperature sensors etc also with, say, different ESCs, different motors and different props, or maybe you just like to lick the electricity and chart down how delightful it felt: You want a source of power that is consistent as a battery pack's voltage, and voltage sag, weakens from one ten second run to the next. Powering your plane with your power supply instead of a pack will yield better testing results. Provided, of course, the PSU can put out enough amps without dying, and without excessive voltage sag. And provided, of course, that the PSU in question won't break the bank, and the guy who sells it to you is trustworthy, based on my having bought...Continue Reading

May has been exceptionally warm here in Finland and that has meant good flying opportunities for hobbyist. During weekend I visited Piikajärvi airfield where local flying club was spending their bootcamp. The location turned out to be great, there was plenty of space for both full size airplane / sailplane activity and RC flying. They also had nice club house etc. The place is certainly worth visiting again!

I flew my new Extreme Flight / 3DHS 95" Extra 330SC and old 70" Extra EXP there. Weather was somewhat gusty, but bigger planes didn't seem to be too much affected by it.

Took plenty of pics. View full gallery here.

It is that time of year again. The weather is getting warmer and more inviting.

I have not been spending as much time in the shop lately. It is hard to stay in the shop when it is a perfect day for flying or running on the pond. My current project is a 53" Cat hull. I'm hoping to have it ready for our summer vacation in 2 months. Time will tell.

I am still working on the plexi glass sign. It is harder to draw in Sketchup than I thought.

That's all for now. Have a great summer.

Being obsessed with brushless whoop I just had to gomahead and order one of these.
https://www.banggood.com/Happymodel-...244425201308OD

It's an absolute bargain at just over £70 if you get the standard version with 3 batteries AND a 6 port charger.
Receiver is built in too so very small and light.
Brushless whoop is the future in my opinion.

If anyone is thinking about a whoop then THIS is the one to get I think, especially for indoors with it being same size as a normal whoop and no brushed motors to wear out.


The slightly bigger one was tempting too but I already have 3 75mm brushless whoops lol
https://www.banggood.com/Happymodel-...244425201308OD
Same price though and probably a little better outside ..

I also have another brushless whoop in the 65mm size on the way from hobbycool http://hobbycool.com?afmc=2j and will be putting a xm+ on it so full range brushless whooping in tiny format!

This video is the Outdoor Maiden Flight with the AOSENMA CG035 GPS WIFI FPV RC Drone Quadcopter With 1080P HD Camera. It shows an Outdoor Maiden Flight and some basic functions, such as the GPS Mode and Altitude Hold.

Outdoor Maiden Flight - AOSENMA CG035 Double GPS Optical Positioning WIFI FPV With 1080P HD Camera (4 min 8 sec)

Review Notes:

Pros:
- Long flight times
- Handles wind well
- The GPS is locked in along with the altitude hold while in GPS Mode
- Props are crash resistant, even without prop guards
- The looks very cool
- It comes with a 1080p HD Camera
- The app has many functions, but I did not try them out on this flight due to time constraints. It was good to just get it up in the air and fly it though.

Cons:
- It had some shakes in the air, but was most likely due to loose prop nut.
- I lost a prop nut after a hard landing off-camera, so make sure yours are very well secured. I thought mine were on tight, but they weren't.

A Cuban-operated airliner with at least 110 people on board crashed into a cassava field just after takeoff from Havana's international airport on Friday. There appeared to be mass casualties as Cuban officials said three people had survived, but had yet to give an official toll. Authorities said there were 104 passengers and nine foreign crew members on the flight that was headed to the eastern city of Holguin. Witnesses said they saw a thick column of smoke near the airport. Authorities are still gathering information about the crash and cannot confirm if Americans were on the flight or not, a U.S. State Department official said Friday.

About a month ago I wrote about a micro size drone kit. The drone's frame isn’t so small (90mm) but the whole thing only weighs a few grams more than a “Tiny Whoop”. I don’t have a yard or a field nearby. But, I’ve got a bench outside my building and that is where I’ve been. I was astonished by the drones outstanding performance outdoors. The FPV signal carries for just over a block (100m). It’s great fun flying around the neighborhood. Over the past few weeks the configuration has been tweaked to the point of perfection. The combination F3 flight controller and 4 in 1 ESC is working flawlessly. The 0703 15000KV brushless motors are very quiet and after the flight they're still cold. I believe this is due to the DShot 600 ESC protocol and Dynamic Filtering in Betaflight. The motors and 3 blade props produce an abundant amount of thrust and the drone could afford to gain a little weight. So today, I’m building another Happymodel Trainer90 and I will continue to experiment.

Latest test results are in. I am in complete remission! If I can hold this newest scan results for 5 years, they can declare me cancer free. It's been hard, but with faith and family, I have prevailed! My health has suffered from the disease and from the treatments. I may never be able to chase down my planes, so won't be flying, but then I never did much flying anyway, as I just sucked at it. Ground vehicles, grandkids, other minor hobbies take up my free time, so all is good in my little corner of the world. Thanks for reading, and thanks for all the support and friendship.

Hello Friends,

I've been working on my project for more than 2 months. Initially, the problem was the fabrication. Overcoming the problem, I've made my design of ornithopter. But after assembling and purchasing electrical components I'm stunned by the results I'm receiving from my bird.

I've mounted a spur gear on a motor shaft which in turn drives another gear. One wing is attached to this gear. This gear flaps this wing and is in mesh with another gear, with which the second wing is attached.

I'm using an FS-i6 for controlling. FOr my mechanism to fly, I need 360rpms. The motor is working fine up to 120 rpms but when I increase throttle, the motor slows down, produces strange sound and suddenly stops. I've to bring the throttle back to 0 and then repeat the process and it always stops.

I've done every fix that could fix but nothing is working for me. The motor works perfectly on full throttle on no load conditions. but whenever the spur gear is mounted (which is called driver gear or pinion) it start producing strong vibrations and suddenly stops . Both the motor and the ESC are very very hot after motor shutdown.

I've checked all connections and made new ones but that do not fix. I've tried changing End limits on Esc but that too dont solve my problem. I've purchased another motor of the same type but it also does the same thing.

I'm very confused and don't know what to do. Any help would be highly appreciated.

So I recently reviewed the ZOHD Orbit Wing on my channel. I was so impressed with the build quality and thought that went into this affordable PNP stabilsed airframe that I instantly knew right then that I'd want more from it. For those not familiar with this aircraft lets start with that review:


So as you can see a little gem. Lots of flight time, decent amount of space for its size and ridiculously portable.

It wasn't without its challenges and as i mention on that video I, a Futaba user, had some serious issues getting the standard stabiliser to work with my TX/RX. The fix is a little quirky but does work and I did another video of this just in case others have the problem:
