I have been flying RC since about 1980. At first, I was highly influenced by pattern flying and spent hours working on slow rolls, point rolls, etc. When 3D became popular, I scratch built a number of glow 3D profiles and learned the standard low and slow vocabulary on these, and then began working on this style with larger 3D gassers. In the last few years I've been enjoying foamies and spend a lot of time working on what I now call freestyle flying ( a combination of 3D, XA and precision) in the parks. Even though I still get to the club field at least once a week, I far prefer practicing alone with a foamie.
When it comes to skill I'm just an average duffer, but I truly enjoy trying to improve.

Oh yeah, my user name came about because I recently bought a new Harley Sportster 48. Love that bike!!!!!

For those who would like to build a sailplane setup using the FrSky Operating System on their Horus transmitter but need help getting started or want guidance applying some of the available features, this guide is for you. The approach taken is building a setup from scratch rather than a feature-by-feature description.

The guide was written with an X10s using 1.3.04 firmware and the model files attached are for that system. The Guide and sound files should apply to the X12 as well but the model.bin files will not AFIK. These files are not necessary for following the Guide.

I can consider myself a glider guider by only the loosest definition so I hope my assessment of desired behavior is close enough to be useful and that this guide will save some people time and frustration figuring things out.

The Beaver kits have arrived at the port in LA and are awaiting submission to customs, so they're still on-track.

Just had a blast flying my UMX Mig-15 ducted fan jet for the first time!

I had only flown very cheap planes before this, but really was only interested in this style plane for now and Im very happy after the first flight.

Safe allowed me to slowly learn what the High rates and AS3X mode will feel like on first flight.

Highly recommend the plane, its a joy and a cool piece of history. Just add the park flyer plastics nose and wing tips for added strength, and check all serves before flight and youll have a great time.

Im a complete rc plane noob by the way. Awesome.

Test Flight #1 - HK FW190 WarBird Crash #2 Repair!

Here is a link to the Video:

I have everything repaired after my 2nd Crash with this plane.
I replaced the Motor Mount, 8x4 Prop, and installed a new Receiver.
I don't know if the original Receiver is bad or if it just had a blind spot.
The original Receiver has short antennas and the replacement has long antennas that I have well away from the electronics and obstructions.

Repairs Completed: New Motor Mount, Straightened and re-attached landing gear, replaced the Prop.

This Kit is discontinued but they still have the F6F Hellcat ;-)

The Growler GX1 is a 2WD large scale buggy with brushless drive. The vehicle is comparatively compact, its dimensions are similar to those of the 1/6 FG Marder. Therefore the car is easy to handle and transport. Nevertheless it has a battery box, which can even take 2x 4S batteries with 10000 mAh with ease. This allows long run times, although the model with its high-torque 680KV/5.5 kW motor has a lot of power. The standard 8S/200A speed controller comes from the renowned manufacturer ZTW.

If you’re still lurking for even more power: motor and gearbox have also been tested with 12S at UFRC, the battery box also offers enough space for 2x 6S. The Growler GX1's stainless steel ESC mounting bracket also offers space and hole pattern for the large 12S/300A ZTW Beast ESC. In order to keep up with this power in the long run, a heavy-duty version of some of transmission components is in developement.

The features of the Growler GX1 are impressive and prove that the UFRC Growler GX1 is an exceptional car. Also the parts’ dimensioning of the largest 1/5 cars was transferred into a 1/6 model at many points.

The wheel hub has standard dimensions with 24 mm hex and 18 mm rim bore. All Losi, HPI, MadMax, GRP, MCD etc. wheels will fit on the UFRC Growler GX1 without conversions or adapters.

Instead of aluminum wheel nuts with fine thread, the UFRC Growler GX1 uses normal M6 screws with countersunk head for wheel mounting. Strong and cheap to replace if necessary....Continue Reading

Is anything worth waiting 3 months for ? ( Maybe a liver or heart transplant )
At last , when I saw this kit ! I thought it might be interesting .

Oh ! It is interesting !
Seriously , there are so many ways to build / assemble this kit , you might be spoiled for choice .

Build it as a Rudder / Elevator / Aileron / Motor ... OR ... as a Elevator / Aileron / Motor ... OR ... Rudder / Elevator / Motor
Ailerons - How many servos to you want to use ? 2 or only one ?

That motor mount is really well thought out , but I wont be using it . I already have a motor in mind and it simply can't be adapted to that mount .
So I will be going in a different direction with the motor ( 7x4.5 prop @ around 5A full throttle )

Single Aileron servo ? Would have to be 9g , elevator servo - may as well be 9g .
ESC , Im thinking 10A or 12A ( depending on whats on hand ) , I did just get a 6A esc . ( But a little close )
That 6A esc is earmarked for another motor and project .. ( Possibly a depron Ezio clone )

Mounting the wing ...
I see 3 ways of doing it .. Some sort of a plate glued to the fuse to put screws thru ( wing hold down )
Glue the ply plate in place , use a rod , and use rubber bands ..
Or a rod at the back and front of the wing ( holes are there ) and just use rubber bands ( X pattern ) to hold the wing to fuse old style .

MG 800 ...

Horizontal stabs are two piece , hmmm .. Would need some sort of joiner .. ( Not...Continue Reading

Bucko is another name for a Bronco, which is what inspired this little plane.

I already have a Bronco (see earlier blog post) and I have always been impressed with the way it flies.
Therefore I decided to make a sleeker and smaller version of it.
I also wanted to try out a few new methods of building.
The entire airframe was hotwire cut from XPS foam and then covered with brown paper and wood glue.
This made for an extremely rigid airframe, albeit a little on the heavy side.
But the excess weight has not adversely affected the flying qualities as she flies just as well, if not better, than the Bronco.
In fact, to say that I was impressed on the maiden flight is an understatement. She is an extremely nice flying little plane. Fast, aerobatic and very easy to control.

Wingspan: 850mm
Length: 640mm
Weight: 670grams
Battery: 3s 1300
Motors : 1700kv blue wonders
Props: 7x4 APC
ESCs: 20A
Servos: 9g

The factory will start shipping the Paladin PL18 on July 25th (Beijing time). This is also the time in which the FlySky Paladin PL18 will be listed globally and I hope I have time to talk to everyone before launch.

1. Testing the PL18
In preparation for the PL18 launch, on June 25th (Beijing time), FlySkys General Manager Mr. Liu Feng, our team of testers and professional level pilots carried out the last of a long list of comprehensive tests. The testing involved many model types including fixed wing, gliders, helicopters, delta wing and multiple rotor aircraft, among others.

We have 10 FlySky internal testers as well as 15 professional pilots from Australia, Germany, South Korea, Hong Kong and China mainland, specializing in cars, racing boats, FPV, Helicopter, fixed-wings and multicopter. After 6 months of testing and countless bug fixes we are happy to say the final tests indicated that the PL18 has surpassed our expectations.

2. Why does PL18 be waited for so long before its releasing?
We have spent a lot of time coming up with new design iterations from the initial FS-i18 to the FT10, and finally the PL18. This gave us lots of space for experimentation with new software platforms (some are too unstable and react too slowly), more iterations in hardware, UI, switch position, hand grips antenna optimizations, ergonomics, RF development and extensive testing.

Happymodel XT30 Plug Pigtail Power Wire 100F Capacitor for Mobula7 HD Sailfly-X TRASHCAN UR85 UR85HD Crazybee F3 / F4 PRO Parts

Wholesale link

Wire length: 70mm(include xt30)
Height: 2.6gram
Used for : Crazybee F3 / F4 PRO series flight controller
Can avoid the risk of burning the mosfet or the 5v regulator at the moment of power on
With this Capacitor , we can use 3S 300~350mah battery for the Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1 , and 2s 300~350mah battery for the Crazybee F4 PRO V1.0
And if you want to use the battery above 350mah , we recommend use 220 uF or above capacitor.

We found most of the 5v regulator and esc of the Crazybee F4 flight controller burnt after mod the PH2.0 to XT30 . Also, more powerful the battery is(lower esr than stock battery) , more possibility to fail. And, the temporary solution is add a low esr capacitor onto xt30 connector. This capacitor should have a esr less than 0.2 ohm and have a capacitance more than 100uF. Rubycon ZLG/ZLH series and Samyoung NXB series are what we have tested and recommended.
Following pictures show what happened after plug in battery:
Without 100uF, the max spike voltage increase to ~25v while with 100uF it decrease to about 20v, which is acceptable to Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1

A few hours after finishing the build, I was flying it in fpv for the first time and was having a great time. Then I flew right into the long edge of a van door (my van!! no noticeable damage tho!). Some frame damage, and one motor got popped open. Luckily, there is no further damage! New frame and set of motors has been ordered. This is why you all said to buy an extra frame right away, isn't it.

In photos:
The bent standoff soaked up much of the crash, and the camera was spared by only half a millimeter! (hard to see in the pic)
The GoPro was ejected immediately, snapping the 3 zip-ties holding it down. Velcroed down for the pic. Crash footage coming soon!
