Just finished this build today. Used this frame available on Armattan. 1-2s BetaFPV F4 FC, 0802 22,000kv ball bearing motors, NewBeeDrone AZI quad blade props, and a NewBeeDrone Goober canopy with an Inductrix AIO camera mounted in it.. This thing is a little ripper and handles great! Immediately became my favorite new micro for backyard and indoor flying.

I've seen several methods to enable and disable the throttle output. Here's my current one. This works for me; make sure whatever you implement works for you. Be safe: Test thoroughly, and never trust an idle prop when the battery is connected!

FEATURES:
  • The throttle is initially disabled when the model is selected, even if the user skips the built-in startup throttle warning and leaves the throttle stick raised. "Throttle disabled" is announced at startup, and "Thr Disabl" is displayed on the screen.
  • You enable the throttle by pressing the ThrTrim up with the throttle stick at idle. The throttle will not enable with the stick raised.
  • You disable the throttle by pressing the ThrTrim down. This works with the throttle stick in any position.
  • "Throttle active" is announced and "Thr Active" is displayed as a confirmation when it is enabled.
  • "Throttle active" is periodically announced when the enabled throttle stick is at idle. You could add haptic (vibration) feedback as well. This serves as a warning / reminder when the stick is live but you can't tell it from looking at the plane.
  • "Throttle disabled" is announced and "Thr Disabl" is displayed every time it is disabled.
  • [Optional - see below] "Throttle disabled" is announced as a reminder if the disabled throttle stick is raised.

IMPLEMENTATION:

Setup:


  • Check the Throttle Warning box. This enables a startup warning if the

This is a build log for my newest project, a partially solar-powered, extended X-UAV talon controlled via 4G. The idea is to increase wingspan while lowering weight, carrying fewer batteries. Thus, the rough technical outline of the project is as follows:
  • X-UAV Talon with dual wing extensionw, 2.3m wingspan. Laminated wings to provide the needed stiffness.
  • Controlled using Arduplane, via a Pixhawk and a Rasperry Pi connected to a 4G modem, running UAVCast Pro
  • Powered by a 4S6P Li-Ion pack (21Ah) and Sunpower C60 solar cells

Note that this is NOT a fully solar powered plane, as that would require a different airframe. However, since basically no solar RC plane can fly longer than a full day either, I think the talon should come pretty close to staying airborne for a ~10h day.

The solar setup is as follows:
  • 16 Sunpower C60 panels per wing, and 6.5 on the body, for a total of 38.5 panels, providing ~23V power
  • Genasun GV-10 4S Li-Ion MPPT Solar Charge controller
This power setup should, theoretically, provide a maximum of ~135W of power under ideal conditions. This would equate to ~9A at 14.8V, which is more than enough to keep this plane airborne. However, since real-world conditions will never allow for that level of power, the talon will most likely never fly from solar power only. Thus, we add a large Li-Ion battery that would on its own be sufficient for a couple hours of flight.

Current status:
  • Assemble, tune and test fly talon with dual wing extensions (DONE)

Continued Crazyness Out In the Shop:

The Little Tom Tom is pretty much through it's construction phase...just getting clear coats 'till it's masked off for color.

So now, it's sibling "The Scout" is up for the bench, and getting it's parts punched out and trimmed.

Traxxas has discontinued all the OBA (On-Board Audio) Slash trucks and I was able to locate one of each (2wd, 4X4 & 4X4-Ultimate) from different locations! I plan on keeping one for myself (probably the 4X4) and flip the other one by parting it out and selling it after maybe waiting a little longer for them to become more rare. I haven't bought the Ultimate OBA yet but I'm thinking about this one too, so I might end up buying an Ultimate tomorrow, we'll see. Here is the breakdown of what I paid for the two vehicles I bought tonight...

Total paid was...

$269.95 (Slash 2wd w/OBA - White)
N/A (Shipping)
N/A (Tax)

$439.95 (Slash 4X4 w/OBA - Color TBD)
N/A (Shipping)
N/A (Tax)
$709.90 (Grand Total)


I've always liked the OBA sound and I use to own a Slash 2wd Robby Gordon edition that I ended up converting to OBA myself back in 2016 and documented it here...) I really enjoyed that truck but I was able to sell it and parted out some it (i.e., Robby Gordon orange body) along with other stuff and made a very decent profit so I'm hoping I can do the same again!

I'll update this blog with anything else I end up doing which is why I love this blog btw! I get to keep track of my RC escapades over the years!

Here are some stock pics from Traxxas...

What would you say about 1:12 (maybe 1:10) scale Northrop P61 Black Widow? A plane I have always dreamed about. I finally started drafting first pieces.

1.7m span
Estinated weight 2 - 3kg
Retracts and flaps included. I am not sure about spolireons that may be hard to print and operate. But we will see.
Carbon fiber reinforced - as usual

Hawker Tempest Mk-1 Foamie

I got the airframe cut out this morning, with the exception of the firewall and servo/battery tray...won't take long....but I did something different this time...instead of cutting formers and bending/gluing the slabs onto them, I cut longitudinal sections that are keyed on both ends...then I'll make templates for the taper of both the fore and aft sections of the fuselage, and cut the tapers with a hot wire.

Plans are for a Cobra 2820/14 840 kV motor, 60 Amp ESC 2600mah 60C 4S

Fuselage is 1/2" rigid insulation....Wings and feathers are 3/16" Elmers board

This build is in preparation for a 60" - 66" balsa version with retracts....just want to make sure it'll fly before I start cutting balsa

Have already set up a lot of elec heli, but now with setting up the new BD Axon I encounter a big problem within my DX18 (1st generation-latest firmware 2.07). Within analog switch setup when I move the L lever pot on the transmitter it also changes the rudder/tail slider setup from -3 to +4. This even after setting up a new model and within channel assignment all aux channels set to inh. This movement is alsof picked up within BD software(was not the case with BD 3SX). I can't find a way to disable this !! (Tried already to change both llever values without success and cleared values which are then automatically set to -75 and +75%. After full setup I will fix my tail within rate mode and than move to heading hold to set head and tail gain, save the gains within the software so I can assign switches for self level and captain rescue.
I do not want llever pot mess up my tail slider setup as this pot is easily touched and changed by just handling the transmitter, and I am sure I will forget to check the correct position of this slider before every take off. (have not programmed any mixes Esther, all set inh)
Hope that any Spektrum user can come up with a solution on how to set transmitter software that moving llever does not interphere with tail slider position.

In lieu of any suitable sensored motors, these SI7213 hall effect sensors were released in 2016, roughly 10 years after the lion kingdom took delivery of its last hall effect sensors, the mighty Allegro 13xx series.

The digital signals from the new ones are a pain in the mane to read, but lions can appreciate what a leap they are from the past. Inside this SOT package is an ADC & a full oscillator with no external components. An oscillator used to require external capacitors.


The datasheet says only 2 sensors are required to detect a 360 degree range of angles. This requires extremely precise alignment. The best lions could do was sense within 2 degrees in a perfectly controlled environment. There's a 4 degree deadband where both sensors are saturated, but enlarging the unsaturated range would create a new deadband where 1 sensor was outside the flux.

With the motor bouncing around & dirt, this arrangement would have a hard time getting within 5 degrees. The motor phase goes around 8 times for every encoder revolution. It's definitely going to need an unsensored mode as a backup. That unsensored mode will drive it as a stepper motor to avoid the need for more parts to detect back EMF.

Fortunately, all lions care about is the relative direction to apply torque, to get the motor started. The torque is going to be limited to 5 degree steps. The tires might absorb some of the stuttering & the lack of a transmission helps. The 2 sensor encoder may not be accurate enough to get a totally quiet start, in which case there will be a major operation to replace the board with 3 hall effect sensors.

The Nakajima Sakae 11 had 14 cylinders stacked 7 in front. For my 1/9 scale B5N2 Kate level bomber, I’m only showing the first part.

The goal was to see if an acceptable balsa version could be scratchbuilt instead of purchasing one. This model is stand-off scale so I think it will work well....Continue Reading

Well it's been pretty busy around here. With the shop staying busy and deer season going not much time for anything else. But everyday I do RC somehow. It might me reading up here on the forum with my morning coffee or taping up some foam board for future projects, I try to RC a little everyday. Well remember the buddy I mentioned in my 2nd post? Well he had come up to visit about 6 weeks ago. He was really excited to see me fly and check out the new airfield out back. We got to talking and he had said that he looked into a couple of planes on HH but they was out of stock. I pulled out the tablet and checked for myself and sure enough one of the planes he was looking at was in stock. He handed me his card and said order it, have it shipped here. Cool, done. I had also showed him some videos of Ed's work with DTFB. I didn't think it would be up his alley but he went home ordered a esc/edf combo and visited Dollar Tree Awsome I thought this is gonna be fun.
Well he showed up this last week to hang out and fly planes. He had a newly built [email protected] Jet (thanks Ed) and he also bought a Nano S2 before leaving Dallas. Myself, I have been getting a couple of batteries in here and there. Nothing new, still take off and land in begginer mode but mainly fly in intermediate. So I'm coming along. Here's some videos for your viewing pleasure.

P.S. He hasn't flown in over 12 yrs. Just a very little time on my sim since I bought it a couple of months ago. His interlink has been broke for years too. I just found out today that he bought a new sim.

Dunno why but I got my five hour flight starting out with only five hours of daylight left and I got set up in a 1-26 with a barograph hoping to gain 1,000 meters on a day which looked like it was going to rain at any minute. I guess Im a raving optimist.

To be honest I dont remember the tow at all. Entering the pattern is mandatory if you get down to 800 feet AGL so I probably got off at least at 2,000 feet so I could descend a couple of hundred feet to mark a clear starting point on the barograph for my 1,000 meter gain. I remember going up a bit and then hitting a solid 400 feet per minute climb. There was a white wall advancing toward the airport and it seemed to hesitate right across rte 209. The runway itself is probably less than fifty yards from the road so I had one eye on the pellet vario, another on the altimeter and both eyes glancing at the white wall right across the road.

I was literally counting seconds knowing the altitude I had to achieve to make my goal. I was there but at 400 feet per minute I thought I should gain at least a couple of hundred extra feet. I mean, whats another 30 seconds.

Thats when the lightening flashed from cloud to ground right across the road. Some things help you make your mind up quickly.

I did a steep banked slipping spiral dive with full spoilers. The barograph trace was just about vertical until I hit pattern height. Coming in on 23 theres a bump about halfway down on final. That bump had increased in magnitude...Continue Reading
