UltraUltrix Project - Brushless Motor Selection (thrust test)
When I found out one of the two 1103 motors I had was having issues I ordered replacements. But at the same time I also order a pair of motors I spotted recently that I think may prove more suitable for the modified plane.
The new motors have stators (the wire-wound part of the motor) that are 1/2 of a millimeter in length but are 1mm larger in diameter. I feel that this may give them more torque and prop-turning leverage.
Let's test them and find out for sure.
I am going up from the stock 65mm (2-1/2 inch) props to 75mm (3 inch), so I have to make sure the motors are OK with them. I will be using a 1S-2S 7A brushless ESC for the tests. This ESC runs a bit hot under this set-up, but the test runs were brief. The plane will be using 2S-3S 12A ESC's so not an issue.
These are the motors being tested:

UltraUltrix Project - Differential Thrust (V-tail Mixer)
มุมมอง 526ปีที่แล้ว
This is the part of the project I had concerns about. The Ultrix has differential thrust whereas one can vary the thrust between the two motors via the rudder stick. This has proven a very popular feature, so including it in my 2S project was a must. I modified a V-tail mixer by removing the black JR servo plugs (input end) and soldered 1.00 micro plugs to the existing solder points, and then s...

Onboard 5A ESC vs external 7A ESC

A viewer asked about using the stock 5A brushless ESC built into the receiver. I did run tests with it and I had the camera a recording, so let me show you why I used an external ESC with my motor and prop set-up.
AS3X programming (direction and authority level)
มุมมอง 201ปีที่แล้ว
After installing a 2S-powered Spektrum Eflite receiver in my latest micro RC plane I discovered that the AS3X anti-wind gust system was moving the elevator and rudder the wrong way when I rotated the plane around quickly. AS3X doesn't react to slow motions and it doesn't self-level the aircraft. It moved briefly to fight wind gusts and then returns the control surface to where it was, so you ha...
SpaceX Starship first launch from T-1:00 to destruction - 4/20/2023 -

Official SpaceX video feed of the first launch attempt and destruction of the BFR (Big F_cking Rocket) oddly named "Starship". The video starts at one minute to launch on the clock and includes a brief hold at T - 40 seconds. It ends shortly after the flight video feed ends and we see the inside of the control center with Musk not looking happy. No doubt this will be an expensive recovery of wr...

Schweizer S300 (MCPX BL2 rebuild) Windy Day Maiden
มุมมอง 479ปีที่แล้ว
I finally got some field access to try out the BL2 I got cheap and rebuilt. I kept the Schweizer S300 canopy on it and added a custom-made boom brace as the real S300 has. It was very windy and the heli was getting tossed around. My slope soaring skills kicked in and I found myself flying a figure-8 pattern so that I was always turning into the wind. I eventually switched to 3D mode so that the...

Raw, uncut (and brief) flight footage can be seen at: th-cam.com/video/f1cyLzdgOdY/w-d-xo.html I finally got to test-fly "Frank Three" and everything felt just wonderful. If anything the 20g shell makes it smooth out and fly even better. The bird does not feel weighed down at all, though I'm sure it would probably affect 3D performance. I ordered the body in November but the landing skid was no...
C187 / BL2 Hatch Solution
มุมมอง 1Kปีที่แล้ว
I figured out a way to keep the loose hatch from falling off and getting lost in flight. All it took was the tiny spring from a disposable lighter, a little sheet metal screw small enough to screw into the spring snuggly and a set of pointy needle nose piers to bend a "C"-shaped hook on the spring's opposite end to anchor to the helicopter shell, looped around one of the peg-and-hole posts that...
