No, I didn't build this balsa plane from scratch. It's an ARF. So sue me.

Yes, it's electric not nitro. So sue me.

No, it's not Eflite/Axi/Hacker. It uses Hobbywing/SunnySky parts. So sue me.

It flies great. That's all that matters.

Curtiss-Wright Travel Air CW-14: Between the CW-12 and the CW-16, things at the Curtiss-Wright factory got racey looking and we are lucky to have the fruit of that era.

The CW-14 series was intended to fill the higher performance market than the CW-12. It looked similar but shared almost no parts. The wings were totally redesigned with a new higher performance airfoil and had Frise ailerons. The fuselage was also redesigned and in standard configuration allowed two people in the front cockpit. The landing gear was longer and used pneumatic struts for suspension. The engine was housed in a NACA style cowling unlike most of the CW-12s. Inside that cowling was a variety of Wright Whirlwind series engines ranging in power from 240 to 420hp. And lastly, the tail feathers also got a redesign to handle more speed and power.

The CW-14 found it’s main market as a foreign military airplane. The airplane was heavily used by Bolivia in the Chaco war against Paraguay. These airplanes were configured with single control sets in the front cockpit and a swiveling turret in the rear cockpit. They also had a forward firing machine gun that was housed under the cowling and fired through the prop. Lastly, they were fitted with bomb racks for up to 250lbs of bombs.

Bolivia received 20 of these airplanes during the war and many others went in smaller groups to other South American countries. The total production number is unknown but it was at least 38 airplanes, most of which were...Continue Reading

The LiPo Fuel Gauge can't be set up in OpenTX version 2.3.10 or 2.3.11 due to an OpenTX bug that omitted the option of using telemetry sensors as input sources, but I'm happy to announce that's now fixed in OpenTX version 2.3.12.

Here is a short video on how I build a 1s 21700 battery for a Nanolongrange FPV drone. I prefer spot welding over soldering, it is way more robust. Compared to 18650 you will get a slightly longer flight time. In the last third of your flight you will experience a stronger decrease in performance as the weight of the bigger cell makes the drone about 20% heavier.

I've had the Ultrix for about a month now and admittedly it's the one I always fly first to get me "warmed up". I've thought if I'm going to do a FPV plane this would be the flyer. I saw a few Ultrix FPV builds so far and it looks like a lot of fun. So here goes my version of the UMX Ultrix FPV v1.0

Step one: Cut the nose off... ok this was difficult for me at first. I typically don't like to mod something that flies so nice. I could have just mounted the camera on the top but I want the "unobstructed" view.

The camera in this position is vulnerable to damage so I made a rubber bumper. Looks super crude! I will try a 3D printed version!...Continue Reading

You can add Fly By telemetry to your Spektrum AR630 receiver by adding a TM1000. Unfortunately, the TM1000's are discontinued but I do see them for sale on eBay now and then. Similar to the way a AR636 worked with a TM1000, the Forward Programming in the AR630 interferes with the telemetry in TM1000. So I added a Hobby King receiver controlled switch to turn the TM1000 on and off as needed. So you fly with the TM1000 on and shut it off when you need to make programming changes on the ground.

The wiring on this is very simple. A Y servo cable plugs into your available port. You plug the HK switch and a modified servo cable into the Y. You remove the white signal wire from the modified servo cable as shown. Also on that modified servo cable you cut the red wire and solder the two wires of the switch there. When that is done you just plug the other end of the modified servo cable into the TM1000 and itís all set other than assigning the channel to a switch.

Curtiss-Wright Travel Air CW-12:

In the early 1930s, Travel Air had just joined Curtiss-Wright and the search was on for the replacement to the Travel Air 4000. The first bid from the Curtiss Wright Factory was the CW-12. It was a much more slender design than the 4000 and reduced the seating in the front cockpit to one seat.

Designed by Herb Rawdon (who started Rawdon Brotherís aircraft) and Ted Wells, (who designed a few small time airplanes like the Beech 18 and Beech Bonanza among other things) the CW-12 was mostly intended as a training platform with dual controls. It had a simple welded steel tube fuselage and wooden wings all covered with fabric. The landing gear was a stout design with a proprietary steerable tail wheel or tail skid built into the back of the fuselage under the rudder.

The CW-12 got a number of power plants over itís short production run, each with their own designation. The 12K was powered by a 125hp Kinner. The 12W was powered by a 110hp Warner. And lastly, the 12Q was powered by an 90hp Gypsy upright 4 cylinder. Between the three models there were a total of 40 CW-12s built.

The production of the CW-12 was unfortunately during the peak of the great depression which undoubtedly stunted its production life. However, a surprising number have survived and quite a few remain airworthy or on display in museums....Continue Reading

Just gotta love it when your flight vibes with a good song. I took out my 4-year old Parkzone ArtiZan 1.1m BNF this weekend for some aerobatic practice.

Parkzone ArtiZan 1.1m BNF w/AS3X Golden Hour Flight (5 min 0 sec)

I almost forgot how good this plane is at slowing down and savoring a maneuver. It seems like nowadays a common perception to making a plane better is to just throw more power at it. But the ArtiZan truly shines when you take a moment just to focus your skills on the sticks. This was one of those flights where everything just fell perfectly into place. The ArtiZan remains to be an understated but exceptional aerobat with no bad tendencies and point & shoot predictability - it goes where you want it to and you get what you give it. Perfect.

Add in King's Highway from the Kenny Wayne Shepherd Band and "issa vibe."

Micro Stunt Tundra (6 min 6 sec)


Micro Stunt Tundra =
1306 4000kv Motor / 10 or 12 amp esc ( dont know which ) , and a 5030 Gemfan .
What makes it stunt is the flap to elevator mix ( like on a C/L model ) .

Outside Loop =
Starting with inverted flight , one simply does a loop keeping the loop to the inside ( belly ) .
Sorry , yeah ,, Keep the belly inside the loop ...
You really need some inverted control authority for this . ( Stunt flap mix )

Hiya Gents- I bought and traded for a N.I.B. E-Flite F-18 Hornet. Traded my F.M.S. B-25 and $200 in cash. This weekend I just built and binded this new bird. Multi-tasking reading the thread, building the plane and doing yard work. I have throws, c of g , ect that I will get figured-out in time. Will order 1 more Admiral 6s 4000mah 40c from motion next week.I use this battery in my F.M.S.A-10, BAE HAWK, E-Flite F-16 and F-4.. Really nice foam , paint and great scale detail on this F-18 Hornet.

I can't believe it's been 10 years since my last blog entry here on RCG but here goes my "incident report" of the Hadron's first flight...

Kamikaze RC Airfield, Coquitlam, BC Canada

The Hadron is a medium sized wing. Around 30" wide so it's usually hand launched. I had flown the F27B Stryker a while back and got used to launching them unpowered for safety reasons. The Hadron is a little different and I guess has to be launched full power with finger slicing propeller blades spinning away. I got ready and went through my preflight: 3S 2200 freshly charged and secured, correct propeller, check the CG, control surfaces working, low rates, SAFE, and AS3X all active. I will hand launch unpowered over grass in calm conditions.

This is when I wished someone was taking a video

On the count of three I gave it a firm and steady overhand throw. It sailed nicely for a few feet as I got my hands back on the TX. I punched it and watched as it shot straight up for about 10 feet and then pitch straight down and lawn dart wide open throttle. Crunch!

After I recovered emotionally from the shock, I taped all the pieces back together and got someone to hand launch it for me. I had it WOT with my hands ready on the sticks. It flew magnificently. In retrospect, I think all the stabilization caused the crazy flight behaviour. Post flight someone noticed that in all my flight modes SAFE was activated...

I got the poor Hadron back to the bench and repaired the...Continue Reading

Radiomaster Tx16 and the Turbo Timber (10 min 8 sec)



A) Smooth as margarine !
B) TX16S - Am I loosing some control deflection ? Flying inverted , it really felt like I did not have enough elevator to hold inverted flight . Maybe it was cos I was trying to fly slower ? But it really felt like I had given up some throw , even in rolls .
C) I love the battery Voltage readout . ( Flight battery ) Makes flying so much safer . ( Knowing the flight battery voltage )
D) Being able to customize the main screen , nice !
E) No frequency fine tune . Oh dear ! ( more later )
F) I may try placing the battery a little further back next time ( CG ) , make holding inverted easier ? , one hopes .

Ok so , I am missing the frequency fine tune . Though the Tx16 is really smooth and precise . That roller / clicker is a PITA . I was getting more Signal warnings with the Tx16 than with the Qx7 + Multi protocol module . A lot more . ( Need that freq fine tune ) .

Aside from some things being (?) what they are . Scroll wheel / Switch crowding / Freq fine tune / some loss of control throw (?) I will have to check that .
Maybe it's just how the Tx feels ? Maybe it's too smooth and precise ? Flying a model , the Tx feels great on the gimbals and the model just flies smooth .
Too much of a good thing ?
Maybe I need to back off on the Expo ?
Either way . Id say over all that the Tx16 is a fine radio .. lets not forget that warranty thing if you...Continue Reading

The motor encoders proved to get dislodged quite often, requiring field calibration, so it was time to finally make a filesystem. To keep it simple, it's a linked list of files. The filenames are just numbers. It just appends every new file to the end of the list. When it runs out of space, it erases all the flash & rewrites the unique data to the start. The cause of running out of space is normally a motor table, so the file ordering usually ends up being a config file followed by a motor table.

The trick is the unique data has to be smaller than RAM for the erase to succeed. The RAM is currently configured for 81kbytes & the flash is configured for 16kbytes. There's no way to erase a single file at a time. If the list is too large to be traversed before the watchdog timer expires, it could get stuck. Corruption with 0 length files is quite easy, but it gets the job done.

First time blogger, here in the rolling hills of Wiltshire UK. Just getting back into slope soaring again after an eight or ten year break, older, fatter and much less fit than I used to be, feel the need to walk more around the local countryside, and the local hills in particular. I am quite lucky as the village where I live is in a valley and can fly off the slope in any wind direction, with a two to three hour hike to get there and back again. Of course its only ten minutes by car, some even less, but wont get fitter driving about, so will be generally walking to the slopes.
First hike today, and decided to carry two planes, a 48" Lumberjack that I have had for years, and an AHI which is new and only flown it once so far, in a rather light wind. Conditions today, thermally and rather light wind, 5 to 7 mph on the edge and dropping to zero, so a bit light for both planes but managed some flights with both, nice long grass for when I just ran out of lift. I had plenty of time to think though, between flights. What sort of planes do I want to fly? How to carry them to the slope with the backpack and bags that I have? What sort of planes would I like to build?
The AHI breaks down, which is why I bought it, though more fiddly to put together on the slope than I imagined, so carried it ready to fly this time. The Lumberjack fits onto the back of my pack no problem, just have to remember I am a wide load!!! Need one or two other somethings...Continue Reading

◄► PART II

The Post .. CHAPTER ONE ..

In May or June, when, though winter is not over and the sea
is still frozen solid (صلب) , the air is clear and one can see (بصر) for miles, the arrival (وصل) of a sled provides a spectacle that goes on for two hours.
Everybody is out to watch (نظر) its progress (صار) , and never Breton sailor
nor Nantucket widow stared (حدَّق) at incoming ship with a gaze more
intense .. (دقَّق النظرَ) ..

For one thing, a sled on the frozen sea is the smallest (صغر)
object in the world, smaller even than a boat seen from the air as
it crosses the ocean. It is microscopic, and I mean by this that it
is not related to anything human. Its movements, its changes of
position, are perceptible only by the half-hour .. (إِدراك / das Erreichen ) .. Its load may be two or three .. (قاس) .. feet high; its length will be, say, fourteen feet: what are such dimensions against a sweep of fifty miles? ..
