The XLF F16 is a Ready To Run (RTR) 1:14 scale 4WD off road Radio-controlled racing buggy. It notably includes a very large 550 sized brushless motor and a number of 'upgrade' metal components including suspension arms and knuckles. The brushed version as reviewed here retails for around $100 and has options with one or 2 batteries.

Here is my in-depth review and comparison to the highly regarded WL Toys 144001 with which it competes:

After 2 separate flying days and watching a fellow club member tweak and fly this plane, I had to order it Tower Hobbies. I also; ordered the same power system as he did saving a good amount of dollars, should be under $200.


I will put up a "Build Log because there are a few things that should be identified since it's been available for for some time now. I'll start by saying that at the time of starting this post, I purchased the UPROAR V2 for $99 and went elsewhere for the Power System.

Out to the hill today with a forecast of 12 to 13 mph and a 2 hour window of the correct wind direction .
On the way up I was greeted by 2 pairs of Red Tail Hawks cruising the slope and screeching theirs songs -a Good sign !
Once on top I was greeted with 15 gusting to around 20 -Yea !

Lately I have been on a mission to complete old projects and get my shop and bench cleared for some new ones, with today's the milder wind prediction I elected to bring out a little ship that had been collecting dust for way to long - A scratch built "Limit Ex " that I built in 2011 ...way Too long

The Limit went out first -it needed some up trim , and the aileron throws were "Very aggressive " she is a nimble little beastie
after about 5 minutes I brought her back in and programmed dual rates and a bit of expo - back out she still had a blinding roll with 60% throw but now comfortable .
Tooled around some more and brought her back in to move the battery back about 1/4 "
spot on - she flew flat in the gusts and the lulls ,flew for another 25 minutes , what neat little bird

After a brief rest I put the 1M Epee out - no surprises here ,I could elevator her up and out of sight or rip back and forth across the face of the hill
After 2hr's I was content to pack up and head back down the hill

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:
  • When you select the model in the transmitter, the throttle is initially disabled even if you skip the built-in startup throttle warning and leave 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 any throttle stick 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.
