I've been looking for a Battery Meter for quite a while.
I wanted one that could also use a 1S LIPO and LIHV LIPOs.
I came across this G.T. Power 1S-8S Battery Meter, Discharger, and Servo Tester that also supports LIHV LIPOs ;-)
Since I already have a G.T. Power Load Meter that I really like I purchased this one.
It works great and now it makes it much easier in the field to test batteries without having to pull out my multimeter.

Foxeer Pico Razer 1200TVL 12*12mm Mini FPV Camera CMOS 4:3/16:9 NTSC/PAL 3.8V-16V for RC Racing Drone

The decision was made to stuff electronics in the latest design. The inductor ended up on the bottom to make more room for the battery. The wires need to be repositioned again to make still more room for the battery.

The eventful run featured fluctuating center values for the throttle. It didn't have enough power to go into the wind. A narrow tire got stuck in a storm drain. The battery cover fell off. Finally, the encoders got knocked out of alignment & a motor started spinning in reverse.

The mane problem is lions are using the speed buttons to go faster, which is bashing it a lot more. The next step would be softer tires.

Sorry, KFm2 as it only has a single step on top.
Bought a few sheets of 8mm EPP foam and built a SuperFly clone (only about 2/3s sheet) based on 24 inch one here: https://www.rcgroups.com/forums/show...light=superfli Go there for dimensions - very nicely laid out.

Ready to maiden, maybe this afternoon. Built one of these years ago and really loved its controllability and fun factor. Also, I have less space to fly in here in my newer location so needed a baseball field size flyer. 230 grams AUW and using a tiny 1806/2400kv motor that I salvaged from a totally useless 800mm wing I finally decided to quite playing with. 800mah 3S lipo. Bamboo spit and a couple of CF spars. Also made control rods out of paper clips and bamboo spits because that's all I had around. Fins are super small but I often fly my wings without any fins at all so used to a little waggle. Cut prop slot too big but oh well, its a throwaway plane. Couple hours work. Maybe laminate it later.

AGFRC has been in business since 2009. I first learned of this brand with this thread over on RCTech: Digital Servos from China when someone linked to the thread on some other random post in late 2019.

The Good:

What drew me into the brand was low pricing to where I could get these servos for $45 each after my frequent buyer discount from Banggood based out of China. Here was my first purchase on Jan 10, 2020:



I installed the following servos in each respective race class that I was running at the time:

A80BHM --> TEKNO SCT410
A62BLS --> PR Racing 401R ( 13.5T 4WD Buggy on Turf)
A62BLS --> PR Racing 401LW (13.5T 4WD Buggy on Dirt Oval Latemodel)
A62BLS --> PR Racing 401R-T (5.5T 4WD Mini Truggy on Turf/Dirt)

These servos were amazing at the time, super smooth, powerful and fast... by far an amazing deal for only $45 each, I hit the jackpot!!!

Or so it seemed...

The Bad:

Over a 4 month period I stripped the gears on the A62BLS in my Mini Truggy a total of 3 times, fortunately I was able to get replacement gear sets but after shipping it was costing me close to $33 a set for each order, $20 for shipping is just insane!



So my $45 servo had just turned into a $145 servo after the cost for replacement gears, yikes!

It's worth pointing out that it's widely accepted that a 200oz-in servo is recommended for Mini Truggy, here's a screen shot from the TEKNO ET410.2 manual:

This is one method of setting up Crow on a Spektrum AR9350 receiver and a compatible Spektrum radio, DX9, iX12, iX20 and more.

This information came from RCG member simages. He dug thru the long history of this receiver and figured out how to get this to work.



In the AS3X app, set up the AR9350 as a Flaperon wing type and normal tail type.



In the AS3X app, on the Port Assignment page, set Gear to Port 5 & Aux1 to port 7

The Kinner K, K5, B and P Sportsters:
Kinner was started in 1919 producing aircraft engines but in the 1930s they decided they would try their hand at producing airplanes. Their first entry into the civilian light monoplane marked was the Kinner Sportster, a handsome two seat side by side low wing with a tail dragger configuration. They were open cockpit with an optional enclosed canopy. But their most unusual feature was their handily folding wings. They were pulled along by Kinner’s own already popular 5 cylinder radials of increasing size from 100hp to 125hp with post factory modifications up to 160hp. The Sportster was intended to sell to the general public as an attainable light plane, it was priced at $2,490 or around $47K today. With at least 39 built, it was successful enough to whet Kinner’s appetite for airplanes. Today there are several restored Sportsters still flying across the world.

The Kinner B-2 and B-2R Sportwings:
One year after the start of production on their Sportster (see previous post) Kinner began tweaking the design and came up with the Sportwing. The Sportster had a few downfalls to its name. Most of all, it was slow and a bit cumbersome. The Sportwing brought some solutions to this issue. Firstly, it had a shortened wingspan to increase the roll rate and lower the drag. Secondly, it added a nicely faired set of wheelpants to the landing gear so as to reduce the drag of the support struts and wheels. Lastly, some of the Sportwing were built...Continue Reading

This is the Maiden Flight of my Parkzone Albatros D.Va 1070mm BNF, won from a Private Seller off of eBay and purchased brand new in the box (BNIB).

Parkzone Albatros D.Va WWI 1070mm BNF Maiden Flight (4 min 19 sec)

I will still never forget the time I walked into my local hobby shop eight years ago and saw this model on sale for $149.99. But because I was new to the hobby and only learning the basics with a Hobbyzone Champ at the time, I walked away from this model.

I regretted that decision.. as this model, along with the SE5a was shortly discontinued.

However, things worked out in the end and I managed to find this one again. I don't regret getting this one at all - It is a beautiful WWI flying icon with a rich history behind it. This model flies beautifully scale and is all eye-candy with a lot of presence.. either on the ground or soaring through the air.

Something unique, something special. I like it a lot, and I'm grateful to have found the Parkzone Albatros D.Va again. They definitely don't make them like this anymore.

MODIFICATIONS:
1) Spektrum EFLR310013 Apprentice S AS3X / SAFE RX.
2) Carbon fiber flat spar .057" x .177" x 17.0" embedded in bottom wing.
3) Light detailing applied to plastic engine.
4) Minwax Satin Finish Polycrylic-protected airframe (2 Coats).

SETUP:
1) Transmitter - Spektrum DX8 G2.
2) Battery - Roaring Top 3S 1800mAh 45C Lipo (152 Grams).
3) Center of Gravity - 60mm from leading edge of top wing.

How many retractable gear parasols can you think of? Probably not very many. In 1931 the Army Air Core was looking for a new observer and Curtiss had a unique solution. A monocoque all metal swept wing sesquiplane with a 650hp Wright Cyclone named the YO-40 Raven. The prototype was completed and flown in February of 1932 but it was wrecked shortly thereafter in May of the same year. Back to the drawing board, Curtiss rebuilt it with stronger wings. They also added full canopies as opposed to the open seating for two of the initial version. Nearly satisfied with the new “YO-40A” the Army Air Core ordered a further four of them with a few modifications. Curtiss delivered on this order with four shiny new “O-40Bs” this time with no lower wing. The upper wing, now with retractable slats and flaps, was braced to the landing gear hard points with V style struts. They had also replaced the engine with the newest version of the Wright Cyclone, now making 670hp. In June of 1933 the four flying O-40Bs were delivered to the 1st Observation Squadron. No more O-40s were ordered sadly and the four airplanes were retired and presumably recycled in 1939....Continue Reading

In 1932 the search for a monoplane fighter for the US military was in full swing. In December the Navy had ordered a new low wing monoplane from Boeing. However, Northrop was leading the pack at the time with high performance low wing ships. They had the already had huge success with their Alpha, Beta, Delta and Gamma monoplanes. In May of 1933 Northrop got their chance in the form of an order from the US Navy for one prototype fighter to be designated the XFT-1. Northrop eagerly got to work on its new single seat ship and in December it took to the air. Powered by a 625hp Wright Wirlwind, it had a design that looked a bit like a shrunken down gamma. It maintained Northrop’s signature wing and spatted, fixed landing gear design. It was constructed entirely out of metal using a stressed skin construction method. With a top speed of 235mph it was a good performer as well as a good looker. However the Navy said that it exhibited severe tail buffering in spins and it had extremely poor handling at slow speeds with a very poor forward visibility. In 1935 it was returned to Northrop for major modifications. It received new larger tail feathers and a new Pratt & Whitney R-1535 of 650hp. It was delivered back to the Navy in 1936 with the new designation XFT-2. The Navy was happy that it went faster, but disappointed by the fact that it flew even worse at low speeds. They deemed the airplane unairworthy and abandoned their interest. On the flight back to Northrop, the airplane was destroyed in a spin accident in the Allegheny Mountains. While it didn’t win a contact, it certainly had good looks going for it.

The next tire was designed to be perfectly smooth for maximum silence & used about a buck of material. The treaded tires already had trouble gripping plastic surfaces, but lions are desperate for anything to reduce the noise. It was still slightly stiffer than the stock lunchbox tires, but very compliant. The mane problem is the desire for a round surface to reduce wear & friction.

For the round surface to be compliant, it needs to expand axially & compress radially. If it was flat, it would only need to compress radially. Not connecting the spokes to the entire outer surface was an attempt at axial expansion, but it's still very stiff where the spokes do connect. Only a curved sidewall would truly allow axial expansion & radial compression, but a curved sidewall is hard to print.


More ideas are transitioning the spokes to a different axis near the tread. Unfortunately, TPU only becomes compliant if it's curved on 1 axis. If it's simultaneously curved on 2 axes into a dome, it becomes very stiff. The dual spoke idea gets pretty ugly & still has problems.

There's also connecting the spokes only in the center of the tread.
