Well the machines from here on out will not have thrust bearings and let me explain why.
With CNC hot wire foam cutting machines the speeds are relatively slow, there is no drag from the wire in the foam which could be seen at the threaded rods, and complete reversal of direction is hardly ever done and when it is it's done again at a relatively slow speed. There really is no need for thrust bearings in this type of machine.
My prototype machine had none other than a piece of plastic tubing over the rod end that slipped into a bracket to support it, and worked beautifully but I figured that was a bit too "Red neck" for most people so I started to incorporate actual thrust bearings in the machines I was selling.
Not to mention that they are NOISEY and contribute to quite a bit of a load in the system.
Since this will cut a bit of the cost I'll be passing on the savings to the buyers and the price of the machines will reflect that... as soon as I get done retrofitting them.

So I pulled my prized Saito 65 out of the box a few days ago for a touchy feely session and noticed that it was a bit stiff turning over the crankshaft. Likewise the carb arm too was a bit stiff. Apparently I had not properly shut it down and/or put enough MMO in after its last run. My bad. I put some my MMO in through the breather and rotated the crankshaft around numerous times with a prop on it.

Then I figured, what the heck, I'll just run it again this weekend, along with the Enya 60 I picked up recently. Sort of a side by side RPM to RPM evaluation.

So I strapped the Saito onto the bench first.

It started after the proper prime on the first flip. Once it warmed up a bit I recorded the tachometer readings:
9150 RPM WOT
2610 RPM idle.

The Enya 60 started on about the 3rd flip after prime and recorded the following:
8500 RPM WOT
2200 RPM Idle
I believe that I stated in an earlier post on this engine that I would put some gasket sealer on the front end before running. Well guess what? I didn't. As it turns out the front end did not leak a bit during either of the runs. Unsure if that is just a testament to the machining process for the Enya engines or if I just got lucky. Now I did see some seepage of what I believe to be oil from around the head connection. At least I could see moisture of some sort dancing around while it was running. But there was quite a bit of condensation from the intake manifold too.

Both engines were running the same 13x6 Master Airscrew propellor.

Wow, I finally got this little kodo off the ground. Mostly just 6 inches or so but I was able to trim it out, keep it in the air and get it back onto the floor on all 4's.

This is Fun!!

Oddly, I'm only using a space in the workshop that's about 3 feet by 3 feet. Maybe that just sharpens focus. Either way, I'm going to keep at this for a bit until I get fairly good at hovering and then I'll move into a larger space.

Want to learn to do more than just hover your quadcopter? This flight tutorial video may help. Horizontal translational flying is not obvious to most people. We'll start the lesson with simple out and back flying, progress through rudder turns, and complete the lesson with an intro to banked turning.

These important flight training tips will help prevent you from losing your quadcopter. It's very important to learn how not to lose orientation of your quadcopter. This can be done by observings its movement alone. What would you do if one day you flew further away than you could be able to visually distinguish your quadcopters front or back? Also this might come in handy for advanced quadcopters, such as DJI. If one of those notorious fly aways is experienced, simply switch to manual control and follow these procedures to help bring it back.

A simple way to bring it back close to you is to first push forward on the pitch control to gain forward movement. Then notice which direction the quadcopter is moving in the distance. If its moving left, turn left to turn the quadcopter in your direction. If its moving right in the distance, turn right to point it toward you. If it alternates between right and left, just keep matching the direction that you turn with its movement. Remember, if its moving right, turn right. If its moving left, turn left.

Vortex Ring State (aka Settling with Power or the Wobble of Death) is a flight condition common to all rotor aircraft (helicopters and multirotors/quadcopters/drones). For those new to the hobby, they may inaccurately attribute this condition to a fault of their aircraft. But really, it is just a flight phenomenon similar to airplane wing stall. This video discusses its cause, along with demonstrating how to recover from it. More importantly, methods of avoiding it entirely are also discussed and demonstrated.

Some progress done on the Ka8b in the last few days.
First up was the towhook servo. I had to glue a couple of sturdy support blocks onto the cockpit floor, to which I could secure the servo with the supplied screws.
Then I had to choose the longest servo arm available, to avoid that the control rod would touch the underside of the cockpit floor. I must remember to install the battery strap properly before I glue the cockpit floor in the fuselage again, taking into account the towhook control rod movement. I guess I'll glue in a couple of support blocks to guide the rod....
After a couple of tests I was happy with the servo movement, no binding, and a solid connect/disconnect position of the towhook.
Next was a bit of work on the wings. I started with the servo wires, by installing some mpx connectors to allow trouble-free wing installation. I alternated male and female on each wing, so I can make no mistakes when plugging them in.
When I started testing the ailerons, I was baffled by what I saw. In the neutral position, the servo arm was already in an extreme position, which caused quite some trouble for the up movement of the aileron. Another argument for the theory that this bird never flew....
Unscrewing the servo arm proved impossible without some extreme surgery on the wing. Removing the servo doesn't look very inviting either, since it is glued in with plenty of epoxy on the balsa wing covering.
So I had to solve this digitally, against my principles....Continue Reading

Recently bought the Sony HDR-AZ1 and decided to test how well it would do compared to my Mobius while flying my 240mm mini quad.

Note: I only managed to record in PS mode(1080 60fps) using the AZ1 as my SDXC MicroSD card has yet to arrive which would allow me to record in XAVC S format that is supposedly better quality.

I have just started an AQM4 build. I have planned to build a 250 size FPV quadro.
But I think I will start with a Walkera Ladybird . I miss some items before I can build it.

After much playing with LTspice, it became clear that it was erratic with small voltages. Sometimes it would actually work. Usually, it would go to full maximum. With large voltages, it always correctly simulated the difference amplifier.

It was time to build up a circuit with an LM324. Amazingly, it worked. It measured 1-5A nearly linearly, using a length of wire & some spare trim pots.

Using a high rail voltage with voltage divider cut the op-amp dropout voltage by half, making the LM324 reasonable. The bog standard difference amplifier did exactly what a proper INA169 sensor did.

With all the effort in the dynamo & the current sensor, you might as well try making the constant power throttle regulator you always dreamed of. Even with a power factor correcting cap, the current was still oscillating wildly from the PWM. Averaging the current & voltage down to 10Hz made a very stable power reading. It was an actual power reading from a bunch of spare parts.

This is a fine model, well made very reasonably priced and in a very manageable size.

I intend to use this plane to give a home to some spares I have laying about. E retracts, 70 amp esc and any servos I have in the spares box will get some use and I should get some room back in the spares box.

First thing to be replaced on the model are the exhaust stacks. I had a set of 1700mm FMS mustang exhaust stacks so off with the individual stacks and replace in a more spitfire way. Some scrap balsa and a bit of epoxy and there you have it.
