Got a couple of pretty special planes this weekend. Been drooling over this plane for 6 long years. Good things come to those who wait.
We were hoping to get them all finished for an international furball but thought a careful build for a record attempt would be more prudent.
These were so hot off the presses that Tim didn't have time to complete his usual cleanup and detailing. That's actually a good thing so I can give them a thorough inspection and gain a little insight on what it takes to make these puppies.
I carefully sanded the flashing off of the fin on one of them today. It's a beautiful fit to the wing.
Decided to use MKS 6125s on a 4 cell AAA pack. I can fit either a Hitec Optima 6 or a Lemon Recr/Gyro. Will go with the Lemon for now.
Here is the Gizmo thread in the Slope section.

Suggested Elevon throws:
Ailerons = low 3mm , med =5mm , high 10mm
Elevator = low 2mm , med= 3mm , high 10mm+ ( for hover landing)

I'm just getting started with RC's and I was looking for some flight controllers that would last and be very versatile. I found the pixhawk hk32, but I was wandering if it was worth it to get the pixhawk 4.

The Tesla autonomy show had a lot of nuggets about what the typical self driving car startup does. There's a chip which is a scaled up version of a GPU, using stock IP that doesn't use very current feature sizes, but marketed like crazy as a revolution. Something never mentioned before, but which slowly oozed out over the last 5 years is how training the networks still entails manually annotating thousands of images. They have some interpolation, some LIDAR to generate annotations, but most of it is mass Bangalore labor.

A more telling feature was the use of neural networks in place of all conditional statements. Determining if a car was changing lanes was an exercise in thousands of sets of car coordinates manually classified as lane changes. They couldn't just classify it based on x > threshold. Enormous effort was spent doing it with a neural network. How much more effort would have been required to make a pose classifier based on neural networks instead of if statements?


There's still no magic in using a neural network to detect a path. It has to be trained with thousands of images of every section of path in every lighting condition. They all have to be manually annotated or interpolated with path coordinates. All the network does is compress the training set & replay it. The network has to be more like millions of neurons instead of hundreds.

This is a fun conversion of an 11 inch wingspan toy bird ornithopter to hobby grade RC. I bought the Electric Flight Bird on sale and chose the 1-channel version, versus the 2-channel one at a higher cost, thinking of a conversion to 3-channel control. After a few months of experimenting, I landed at the V-tail version-five presented. Not complete, there is still detail to add to the tail and reshaping of the battery mount.

My creation consists of:
- replacing the stock fuselage and tail feathers with balsa, carbon fiber and foam.
- installing a Spektrum circuit board 'brick'.
- adding landing gear bent from 0.020" music wire and held in heat shrink tubing pockets.
- a fuselage 'keel' that permits fore and aft movement of the 1-cell flight battery for CG adjustment.
- flying with a 130 mah Lipo.
- adding a rubber nose cone (from Horizon Hobby micro airplanes) for a beak/bumper.
- replacing the stock crank arms, that flap the wings, with shorter versions to reduce binding.


Worth a closer look are the crank arms that I replaced. The stock crank arms worked fine with the wings not installed. The 6mm diameter electric motor would turn the gears very smoothly from fully closed to fully opened. However, after the wings were installed they would press tightly onto one another in the fully closed position, forcing the motor to push through this friction point. Seeing the problem, I replaced the stock crank arms with ones that have a hole spacing of...Continue Reading

I have a Foxx s911 and when I go straight to full throttle it twitches forwards and the light to the on and off switch blinks but if I slowely speed up it's fine but then I can go in reverse starting with the throttle all the way up. I don't know if it if wiring or what so if anyone has any suggestions or questions pls ask.

Mini Surfer 800 from Banggood com ( CG Games ) (3 min 14 sec)


I put another Lead Ball in the nose ..

CG is now some 10mm back measured from the centre of the spar ..

My first launch was superbly timed as the wind lifted the left wing and did it's best to flip the Mini Surfer 800 onto it's back .
It was so quick there was no recovery .
Luckily the Mini Surfer 800 is a tough bird , and tumbled across the ground sustaining no damage !

My second and 3rd attempts / launches - resulted in some test glides ...
For now I am happy to leave the CG where it is ..

A) Glides ok
B) Controls are not overly sensitive ( This could change under power )
C) Push come to ..... ( its a pusher ) I can always throw another lead ball at it !
D) There does seem to be some tendency for the model to roll to the right on launch ( is that me ? ) , but with the clockwise rotation of the motor , the torque should counter this .. ( Un powered flight so far )

Ok . I think I am ready to fly the Mini Surfer 800

I have an appointment tomorrow , so hopefully by the weekend the Mini Surfer 800 will have flown under power ..

Maiden - Ballsed big time !
