I just crashed my flyzone dhc2 beaver a few seconds after take off. One thing I noticed before the crash happened was that the aileron servos were having a latency (or glitch) on my first turn after take off, the plane didn't roll immediately as soon as I push the stick to the left and right. When I knew things are going to go wrong, I tried to land the plane but I had no elevator control and the plane dove straight to the pavement. Can you guys tell me what went wrong? Could it be the anylink or the radio's battery level or the receiver? Right now I'm trying to repair the plane but I'm not planning on flying it until i know what caused the signal loss.
Please help! Thanks

Hi Guys ,
Do not be too surprised when you see this blog , Do not doubt this 15A Slim ESC .
For the 3D F3P flying , we will required strickly to the weight even to gram , include the cable ,connector and so on .
And current for 10A or 20A if price and weight is acceptable , i prefer 20A better

However i belive this ZTW Mantis slim 15A can fulfil most of your requires , check these data :
Size : 27*14*mm (L*W) , compared to Castle THUNDER BIRD 9A which is 26.8*17.4 mm(L*W) ,How slim it is !
BEC output : 2A/5V continuous and peak can ge 3A/5V but only for not over 5 seconds . but this is enough , as i know other versions 10-20A ESC, BEC is only 1A. continuous.
Current : 15A , this is between 10A-20A . maybe some 3D flying guys have been looking for this .
Price : i think 15-20USD is acceptable . depond on different marekt . As it can be bought from Amazon or other distributors now .
Program : Yes ,it can be programmed by the ZTW program card
Weight : 5.5g does not include the cable . From the fractory , include cable,connector under 6.5g is possible . but if you can DIY , 6g can be realized !
Software : Updated version which with faster throttle response for the 3D flying .

BEC ouput stronger , Size smaller , weight lighter, price acceptable ,software updated .
But personally think , the weight still can be lower a little .

Update on process- Using stock ESC ( eventhough I prefer Hitec) but I'm doing this out of my spare parts bin. Used Tundra rubber tires, didn't have grub nuts so made them out of the bar that comes on APC prop adapters. Using Tactic High speed servos for Elev/Rudder. Used the Durafly prop as the black & white fits the color scheme. Did find a neat little spinner nut in the bin that fits. Used my spare stock motor.

I have the anyFC with 8 open Uarts. I have enabled 2 of them, but one is for my Rx and the other is for my Smart Port. Whenever I enabled any of the others my #3 motor stops working. I am wondering if I am doing something wrong, or possibly somebody else has had this same issue. I have searched all over the internet but their is a lack of info protaining the F7.
If you enable a Uart that I need for RX and TX the #3 motor stops spinning when armed. When I disable the Uart all motor arm and spin correctly and it flies great.
I have a anyFC F7 Flight Controller, Frysky RX, 4 in 1 ESC, and basic 2204 motors.
I have flashed the new 3.2 Betaflight and also flashed 3.17 Betaflight, neither has changed the outcome.

The new Floureon K250 is now available, and brings a few very welcome updates to the tried, and true Racer 250 platform. Click me to purchase.

This new version replaces the 2204 motors of the old 250 racer with 2205 2300kv motors. The old Naze32 flight controller has been updated to an SP Racing F3 FC with OSD. The 1000TVL FPV camera gives a clear, and clean FPV feed, and the new Pagoda FPV antenna gives an improved range with better signal quality.

One of my favorite things about these quads are the lights. The headlights are very bright, and the LED light bar on the back looks extremely cool during night flights. (See pics) They also aid in keeping correct orientation at distances when flying LOS.

These quads are excellent for anyone looking at getting into FPV flight, or those that just want a cool looking drone to fly around the yard, or local park. This K250 Racer is available as a Flysky, or Frsky BNF, or as a PNP model ready for your own choice of receiver. This is also one of the most affordable 250mm quadcopters with the PNP version costing only $121.99 and the BNF versions costing $130.99

I just finished getting mine set up in CleanFlight, and will get some flight video ASAP so stay tuned for updates as I spend some time with the quad....Continue Reading

The other night I was browsing the forums and a title caught my eye,
Depth perception problems and eye tests, by BernardW,
I replied with the following:
About “Depth-Perception” at longer distances.

Binocular (two-eye) vision is great for things that we can hold in our hands, ok out to about three meters, poor at six meters, and not worth much at all at fifty meters.

Probably the biggest clue about distance is knowing its’ size and seeing “how big” it looks off in the distance. (At a distance "how-big" would be a small angle).

Other major clues are its’ relation to foreground and background. When it passes in-front-of a tree we know it is closer, when it passes in-back-of a bush we know it is farther. When it just passes over the bush or the tree we do not really know for sure its’ position.

So... When a plane is flying in a clear blue sky it is harder to guess the range. If trying to land on a flat field with few features then it will be hard to guess its range until it goes below the horizon and starts going in-front-of some features.
Binocular Vision - I learned about binocular vision several years ago when I briefly explored getting into "3D-Stereo-Photography". One of the first things that I learned was that you could have more than just the "standard" 63mm lens-to-lens separation (InterpPupillary Distance). For example you could make a better stereo photograph of the grand canyon by mounting two cameras under the wingtips of an airplane, this would accent the 3D effect.

Foreground-Subject-Background - is something that I learned about when studying general photographic composition. It is also found in stereo-photography, and traditional-cel-animation technique, and adding "Depth" to movies to be shown on flat-TV's

Thanks for reading

The discussion is over here in Aircraft-General > Crash Discussion
He sounded satisfied with the replies that he received, turns out his biggest problem was a crosswind.

P.S. This Foreground-Background idea might be nice to try at an FPV-Race-Course.
P.P.S. Anybody want to try 3D-Stereo-Photography using a 2meter glider?

Hi all,
Great weekend and what a day to go out and get some FPV flights inI took this oopurtunity to test out the Eachine Ev006 mini goggles.I must say I do like them!I also had my Eachine EV800 gogglles on hand for comparison.

The Vr006 goggles performed nicely,reception was as good actually possible slightly better range than my Ev800's.

Screen resolution was good,not as nice as my as my Ev800 but still acceptable.

The VR006 goggles are very small and not for everyone but the worked well for me and were more comfortable than the Ev800,much lighter as well.

I like the compact size of the VR006 goggle ,very transportable,I was able to fit two controlles ,the VR006 goggles and my DYS Elf in one bag,pretty cool

I am finishing up my video review and will post it soon here in this thread,please stay tuned

This is footage of two Gold Edition Top Flite Giant Scale RC Planes at Warbirds Over Whatcom. They are the Top Flite F4U Corsair & Top Flite P-47 Razorback WWII Warbird Formation Flying for those in attendance. The pilots are very skilled and put on a great show, even when dealing with some strong wind.

I've seen an increase in the number of guys asking about video options for long distances, so I thought I'd take a moment and distill my experience from the last year and a half and give a bit of advice to get out there farther. I hope this helps some of you!

I have a Balsa Products Boeing F4B-2 done in navy colors. I'm glad I bought two kits as it is no longer in production. I've just started the second one and it will be the US Army P-12. They were basically the same airplane. I have an OS 160 Twin it the Navy version. Flys very realistic.

Result is sad...

Well my main kwad has cobra motors and cicada 18A escs... flies fine "Locked in"
So I wanted to give another try to some super racerbee 30A I had bought a while ago...
mounted them in place of the cicada... did calibration then went out to try...
I'm so sad because they performs so well and so much better than my cicada...
But they desync hard!...
I did increase idle throttle, switched protocols, shortened pwm from 1100-1900 with idle to 1170... nothing do...
So I've just put back my cicada, did calibration and went out again...
No desync at all flies fine without problem...

Oh my BAD escs!

Thought I'd keep a record of the whole process here. Title the Black and White Tundra. Had all these parts I got during HK sale--so why not assemble a spare Tundra? Trimming plane in Black and White, used Tactic 35 high speed servos, Venom Y harnesses. View comments below for updates.
