To Windy (0 min 27 sec)


WOW !!

I got up around 5.45am to try to beat the wind !
It was really quiet @ 6am
I walked out the door 6.30am ( Sunrise being just after 7am )

By the time I got to the field the wind gust was probably over 20kmh ...

Yeah , the wind has it in for me ( must be personal ! )

Anyways , launched the cub and it did on into such a wind .

I turned left and then down wind , now the cub picked up a lot of speed .

Trying to turn back and the cub was just not cutting it and rather than try to beat the wind I just cut power and landed / put down the cub a best as I could .
No damage , no nothing . Just a damned shame that it is so windy all the time .
What the heck happened to the weather ?
It's never been so windy before ! Decent days are few and far between . 2019 was simply horrendous for wind .
Go back 20 years and nice days were common place , now , rare as hens teeth !

I got this nice twin 70mm EDF kit from BH for $149, including free shipping,

https://www.bananahobby.com/7-ch-bli...f-jet-kit.html

The kit itself is lightweight epo and is made by Lanxiang, it has been around for a few years

http://www.lxhm.us/En/Product/detail/id/22.html

The model is 80.9 cm wingspan, whereas the original has 13.3 m wingspan

https://en.wikipedia.org/wiki/Northrop_YF-23

which gives an approximate scale of 1:16.4 .

As a result, the model is actually quite small for a twin 70mm edf (as opposed for ex. to the Su-57 by the same manuf.)

Hi everyone I have just seen what is described as a carbon Seawind and was wondering how you could tell the difference between this and an ordinary one.The owner says he knows nothing about boats but adds the model No. is K40463RS.

After hard searching for the proper bearings to adopt the sunnysky 2302 motor for a 2.5mm shaft, no joy without spending to much for one bearing. So, while digging through a bin with odd stuff, I came across some compression tubing inserts (brass and stainless steel) that is perfect for this application, The 2.5mm shaft fits perfect into the inserts. The stainless steel inserts needs little filing on the OD to fit into the 3mm bearings. The brass inserts drops right into the 3mm bearings. I also put a insert into the locking end of the motor with the flared end on the outside. The other inserts length were shortened by filing them short and the flared side of the inserts were placed on the inside. I did not put any loctite between the inserts and bearing race, but, if I need to, I will. So far, it's smooth as .....

The entire driveline of the 3mm hisky hcp100s can also be adopted to the k110 to avoid what I did with the inserts. If I didn't find the inserts, hcp100s driveline would of been my choice. And it's probably more robust.

if I had to choose it would be the self winding, my second love next to rotor builds is trying to rebuild time pieces and have a vast understanding of them, with this I present 2 of the 3 heaviest hitters in horology.

Yeah , a actual 1s to 3s ESC .....
I did buy one , and will play with it ASAIGH ( as soon as it gets here )

K110 DMD with my modded k120 to k110 skid for a 300mah 2s lipo.

The brushless motor is a sunnysky 2302 v3 1500kv for 3mm shaft and I added support for a 2.5mm main shaft. The k110 was previously a 2s with k120 brushless motor and this gear less set have lots more torque. With the motor mounted flush to the frame it offers much needed frame support that stops the flexing on the driveline that could break the main shaft guide.

It have two new esc with one for a 2s brushless tail with a 10000kv 1103 motor. The tail esc is running blheli firmware for tail. Holding nice. I also painted the frame and skid and regret it as I don't like it. Will do it over with new frame and a fresh modded skid.

I've done the same (DMD) for two k130 and I like this build best.

Besides carrying a larger 2s lipo, my modded k120 skid adds better front support and ground clearance than the k110 stock skid.

This may sound obvious but only now, after a few years of brushless motor winding, I had this simple but genius idea.
I never realized how useful it was until I did it for the first time.

So, if you are not sure about the original motor kV and can't test it anymore (i.e. burned or damaged windings) or if you are not sure about the results you may get with an unusual and experimental winding scheme, simply pick the smallest gauge you can find and do a test wind.
Using a very thin gauge wire will allow you to quickly wind and check the exact kV you'll get with it. Below is an example with my GA6000 rewound with half parallel dLRK Y wind for 164kV. The subsequent wind with 14AWG got exactly the same result.

Since currents during kV check will be very low, even a thin gauge wire will suffice and provide accurate results.

I got tired of wasting aluminum and or music wire trying to bend landing gear with a vice/pliers/hammer....So I built a 2 ton hydraulic press brake out of materials readily available at HD/Lowe's, and that doesn't require any welding and or special tools....worked like a champ..so I decided to build a wire bending tool.....same deal, no special tools.....drawings are included.....The press brake cost me less and $50 and the wire bender less than $10.....

Y'all have fun

Hi all,

I was working with BLHeli firmware for a while just to adapt the control signal to accept PWM up to 16kHz.
The reason for it was, the WL-Toys K110 gyro board is an excellent flight controller and has the tail signal of 16KHz PWM.

With my limited knowledge, I am create this thread just trying to explain the differences between BLheli Electronics Speed Controllers (ESC).

Currently, there are 3 types of BLheli ESC's: BLHeli, BLHeli_S and BLHeli_32

BLHeli: The birth of an open source firmware for ECS's. The target was for tiny micro helicopters and was
started with the 8 bit ATMEL microprocessor, the mega8.
It was proved to be popular so it expanded into multi-rotors vehicles.

But soon, the mega8 was found to be lacking of resources and power to control various type of motors.
It was then replaced by the Silabs processor. Silabs BLHeli based on these three type of processors:
C8051F310, C8051F330 and C8051F390, the higher the number, the more advance and faster processor.

BLHeli supports MAIN, MULTI and TAIL motors. BLHeli came with two varieties: Atmel and Silabs processors

BLHeli_S: As soon as the BLHeli exploded with multi-rotors vehicles, more advance functions are required so the BLHeli designer switched to the more advanced and even faster Silabs processors, the 'BusyBee' family and they came in these varieties: EFM8BB1, EFM8BB2 and EFM8LB1.
To distinguish from the earlier genrations of Silabs processors, they called it BLHeli_S (which is also very...Continue Reading
