Over the last couple years I've had a Sailfly-X, Mobula 7, and Crux3.
While seeking performance improvements and a replacement frame for the Crux 3 I started mucking around with 3d printing Aerodynamic motor pods strung together with carbon fibre rods.

Currently I am using ABS and 1mm solid carbon rods. The designs are my own and I used tinkercad. They hold the motors captive so in the 3 inch frame for example, they allow for only one screw to be used rather than 2 or 4 screws, saving 1-2 grams of AUW on top of the 1.8g of the crux.

The durability of the frames is yet to be fully determined but I crashed the smaller frame and broke the camera but not the frame.

My 65mm prop size frame is only 1.8 grams (compared to a mobula 7 frame which weighs 4.4 grams) and uses Mobula components. The AUW is currently 18.5g with a trashy 1.7g camera. Soon I will have the EX0802 motors which will shave off another 0.5 of a gram, and if I get a diamond fc then I will shave off about another gram, a runcam nano 3 will reduce it by 0.6

The 3 inch frame weighs 3.8 grams compared to the stock 5.6 grams.

I have more parts coming

This project is very much a work in progress, more is to come.

First off thanks to Bob for the idea and the testing.

A while back I was approached with the idea of making a brushless speed controller that would work on a standard slot car track. There were a number of challenges that we had to solve in order to make this possible. We needed an esc that would turn on and run at a very low voltage, self start and run as soon as current was sufficient. The goal was to make the brushless motor work and feel much like a brushed system where the speed is controlled by varying the input voltage.

The hardware for sub 2v ESC
The stm32g071gbu6 MCU was used
No gate drivers, We are not worried about switching speed as the esc will be in 100 percent duty cycle operation at all times.
Texas Instruments low gate threshold voltage P and N mosfets are used,
Attached you will find a PDF of the schematic. Also the kicad project files. with layout and gerbers

The Software
The firmware is a modified version of AM32 with the signal detection, arming and throttle removed.. replaced by starting at 100 percent immediately. Please physically mark any esc's that have this version of the firmware on, it's not safe for other applications!
The auto startup can be halted by applying a solid high signal to the input. This will make the ESC enter the bootloader mode where it can be re-programmed or settings altered.
A built binary for the board is also attached.
There firmware and github project can be found here: ( will be added soon)

please feel free to use the chat for any questions about the ESC or brushless slot car control in general. If there are any other slot car drivers out there let me know what you think.

Mike,

I've used vellum (tracing paper) to cover a few of my birds (Alvin, Clearprint, Helix, etc). It's a lot stronger that tissue, but not as strong as Mylar, has no directional grain so it shrinks uniformly, and it accepts paint readily.

You can also use brown paper, but it's heavy. I've never tried the iron on fabrics, though lots of people have had great success with it

This is my first RC car. I build it gradually, part by part. The first parts I bought were the wheels and tires, then the chassis, axle and so on.
I really want the RC car that I build will have good performance.

It's been a very busy summer...but lots of fun!

Is there anything better in this hobby than scoring amazing deals and even freebies from local modelers and friends? Yes, enjoying those old models with friends!

In my case, most folks are just thrilled that someone is willing to invest time and energy into making these old models airworthy, and enjoyed again. That was my mission this summer and the result has been very rewarding. Some aircraft required restoration and others were almost ready to fly.

There's a nice mix of 1/4 scale gas, vintage glow/nitro, electric powered aircraft, sailplanes and vintage kits. All have been flown except the PT-19 and the sailplanes. Currently, my favorite to fly is the Balsa USA 1/4 scale Piper J-3 Cub with Zenoah G23 gas engine. It took about two weeks to get it refreshed and upgraded. It's a sweetheart to fly and looks amazing in the air!

There are a number of vintage fun-fly gatherings in the works with models of all shapes and sizes. I'm looking forward to an exciting time, sharing a passion with great friends.

Keep 'Em Flyin!...Continue Reading

This was a little orphan project that I picked up and felt sorry for so I decided to finish it. It had been kicked around from pillar to post with noone taking the time to give it a little love so I adopted it. I put about 150 hours in it to get her presentable enough to be adopted out. I named it "How's it Hangin? BR549.

I loved building the Pat Tritle design Yoda's Ark so much, I desided to build a larger version. The original measure like 26" in length. So I found a fiberglass hull 33" long and thought this work make a good candidate for this project. I had to do quite a bit of build up on the front deck of the hull about 1 1/2" to get the right profile and cut 1/4" off the top of the sides and transome. Built the wood framing to install in the hull and about 400 hours later, here she is. I call her the Lucky Lady.

My good friend Glen from RCPlaneStands.com sent me one of his BenchTop stands to unbox and review on camera.

Description:
Hand-made RC planes bench-top stand. Top-quality, made from Baltic Birch plywood with quality hardware. Works well for medium (30 cc) to large (120 cc) RC planes. Fully adjustable arms and slings, the top of the arms have Velcro with a Velcro one wrap strap so you can adjust them as you move the arms in and out for a snug fit to your fuselage. The sides are removable with 1 screw.

The SPT died the same way the Hextronix died, a sudden full left lockup followed by intermittent restoration after wiggling the cable. Power cycling it did nothing. It's been 7 years of chasing erratic servo behavior. Most of it might be pots & motors wearing out. The last few have been converging on the wiring.


The cable has been already replaced. Replaced it again. This one is coming down to a loose solder ball or dry solder joint. So that's 2 days of not going anywhere because of a retaining ring, dead servo, dead 3D printer.

Besides the gusty winds over Breezy Hill today, Billy and I had problems with cranky engines.
The K&B engine in my Sig "Zlin" has just snapped to a stop at the top of an upside-down/outside loop, but had the momentum to follow on through to a safe landing.

Still a Great Day though!

I recently inherited this rc plane body from my father when he retired and moved out. Im thinking about selling this [since I prefer land vehicles], and was directed by a few people to come here for some help. So if anyone would be willing to help me possibly identify [and price if so willing] what i have pictured below, i would be extremely grateful. The plane is well over 30 years old, since i heard my dad say "i was gonna build it, then i had kids" and im 26 and my brother is 30.

Also if anyone is truly interested, these peices are for sale.

Howdy people

something very different this time on my channel / on my blog
A Helicopter! :O It has been years since I last flew one.. So let's see if I can keep one in the air :P

Link to it: Esky E300 v2 helicopter (at Banggood)

Sooo I will be doing a couple of video's on it BUT again: let's first see if I can fly it :P
