I can honestly say that I almost changed out the motor (Emax BL3526/04) a 860Kv motor with very good specifications that allows up to 5-Cells (18.5 Volts nominal), however, I found a few articles on how to glue back in the lose Magnet from the rotor (rotating bell housing) that contains all of the rotor's magnets.


This was possible because after careful disassembly I found ZERO damage inside the motor and inspection was possible using 30X times magnifying glass (Hand held). The Stator's windings at ALL Poles looked great and sounded great on subsequent test run.

After allowing the Gorilla "Clear" Glue to cure all of it's 24-hours as specified per instructions the motor test looked and sounded very good, like new. I am sharing a few pictures of my model's issue with this motor and I will be now going to fly it with the GForce Elite Series 4-Cells, 4000mAH, 30C Lithium Polymer packs.

Just an amazing Prop Jet model, especially with the Electric Power System. It has been perhaps 2 years that I have not flown it so, I got the step stool and lower it down from hanging all this time. Dusted it off and checked all systems and afterwards, headed to Moon Port on Sunday, 01-26-2020. It flew for 3 flights and didn't disappoint!

A Few high resolution and wide bandwidth pictures can be seen at:

Hello good people!

It has been nine (9+) years and it is still flying nicely! Time and the sun has taken it's toll and soon a re-covering will be in order.

I purchased this from a very nice gentleman from Brooksville, Florida and who I still purchase models from to this day.


It has been a long time and just can't believe this model still places a BIG smile on my face!

Due to the Holiday Activities I have NOT been able to tackle the Scale Printed 3D 9-Cylinder Engine Kit project, however, I did take advantage of ordering a brand NEW Master Airscrew (MAS) 3-Balde, 10 X 7 X 3 Propeller from Horizon Hobby right before XMAS.

It came in speedy priority and I wasted no time and went to work on installing it over the XMAS holiday and finally this morning, January 1st, 2020, I was able to try it out. It is one of their (MAS) new designs with decals on each blade.

It practically transformed this model while using the STOCK Park Zone 480 (960Kv, normalized to 910Kv due to Dr. Kiwi's testing) and it went beyond my expectations just like the older MAS 3-Blade without the decals. As far as I can tell the Airfoil is the same in comparing this new Prop to the older ones.

Believe me, these propeller will NOT break. Your model will be completely destroyed before anything happens to this propeller! Don't ask me why I know!

Flight was just amazing with half throttle it cruised like a home sick dove and continuous KNIFE EDGES was the DEAL as it performed fantastic!...Continue Reading

Okay, Good people.....

It has been a pleasure being part ( a small part ) of this Program and watching the Starliner and Rosie come back to mother Earth!

Congratulations to both BOEING and United Space Alliance (ULA). Boeing for the extreme efforts on building a Spacecraft from scratch and in just under a few years along with other test articles. ULA for their magnificent Delta V rocket and upper stage Centaur.

For those that don't know......

ULA’s Atlas V rocket is a workhorse for the U.S. military, intelligence community and scientific researchers. Developed as a modular vehicle, each Atlas V is tailored to the needs of its passenger by adding as many as five side-mounted solid rocket boosters for increased lift performance and a variety of available payload fairings in various diameters and lengths to protect satellites during atmospheric ascent. The high-energy Centaur upper stage, which has been used to send spacecraft to every planet in our solar system, is incorporated into Atlas V to deliver the payloads to their intended destinations.

ULA's flew the Atlas V rocket with a kerosene-fueled common core booster, two solid rocket boosters and the hydrogen-fueled dual-engine Centaur upper stage.

The descent and landing went flawlessly just like their many previous tests with the test article.

Soon we (USA) will have Astronauts Launch from the Kennedy Space Center, Florida again (US Soil).

Wishing everyone a Happy Christmas and a very good 2020 year filled with good Health!

Airlines frequently redact details of the features they opt to pay for — or exclude — from their filings with financial regulators. Boeing declined to disclose the full menu of safety features it offers as options on the 737 Max, or how much they cost.

@ Peter!

I have uploaded most of the Videos pertaining to the 3D Printed 9-Cylinder Radial Engine Prject Up to Vimeo for a better and slightly larger format, especially when the viewer selects the Full Screen Target: (See Attached)

This allows for several things:

1. It allows the viewer to easily download the video (much easier than Youtube).
2. It allows for a slightly larger viewing format in Normal mode & a much higher resolution in Full Screen view.
3. This additional Video location provides a secondary backup of our work!

Here's WEIGH-IN Session on my E-Flite AT-6 Texan using the Park Zone 480 and the 3D Printed 9-Cylinder Radial Engine Bust.

Previous Post about WATTS - AMPS - VOLTS under Load can be found at:


However, I did perform a new WATTS - AMPS - VOLTS under load test during the night of Tuesday, November 19th, 2019 and here's the data:

I have performed my 3rd WATT - AMP - VOLTAGE UNDER LOAD test on my E-Flite AT-6 Texan that was configured with the Park Zone 480 motor and Castle Creations 45-AMP ESC and using GEN ACES 3-Cell, 2200mAH, 35C, Lithium Polymer battery pack and fully charged.

During a careful pre-test check, I found something wrong with the propeller adapter so, I changed it and it was a simple fix as I had access to the set screw holding the Propeller Adapter and there was enough space for the HEX Tool.

Here's the Video and Results of tonight's Test: APC 3-Blade 10 X 7 and Park Zone 480 Motor

1/4 Throttle - 39 Watts / 3.23 Amps / 12.22 Volts

1/2 Throttle - 146 Watts / 12.85 Amps / 11.42 Volts

Full Throttle - 219 Watts / 20.44 Amps / 10.74 Volts

Here's the previous Thread on this Project:

RE: Accommodating the 3D Printed 9-Cylinder Project!
Busy CUTTING that dang Tough and Hard Cowling with my ROTARY TOOL Set. Then, I finished it with some stainless steel toe nail precision scissors and once I was able to get to the FRONTAL EDGE Smooth part of the Cowl it was a HOME RUN! Hey, it is NOT PERFECT but, I almost threw away Cowl so, it was a good recovery!

For those truly interested in the 3D Printed Project then, please visit Peter's Web Site at:


Many times this dang AR636 upon initiation it moves my Servos really hard to their end-points. Yes, I do realize the Software operation behind this but, when I Bound it to my Transmitter, I made sure that I Turned-OFF the AS3X stuff but, you could NEVER TURN-OFF these Features entirely and I should know because I can hear the Ailerons move slightly when I pickup the model after a typical flight and the initial sequence it moves ALL my Flight Control Servos something terrible!

I finally solved this by replacing it with a Spare Spektrum AR8000 + SAT.

It is now working like a Charm!

No more violent movement of my Flight Control servos UPON initial program sequence!

Additionally, I performed a Center-Of-Gravity check (several) by placing the battery at it's recommended location within the model and it balanced perfectly!

For those truly interested in Peter's 3D Printed Work then, you can visit his Web Site at:

1. Took out my Model Motors AXI 2826-10 as it tips the digital scale at over 7+ oz. (10+ oz with Dummy Engine)
2. Left the PZ-15 aside as it tips the digital scale at 5 3/8 oz. ( ~ 9+ oz with Dummy Engine).
3. installed the Park Zone 480 as it tips the Digital Scale at 3 3/4oz. ( 7.5 oz. with Dummy Engine.)

I was pleasantly surprised how easy it was on installing the Park Zone 480 motor (same POWER as 44-inch Wing Span T-28 Trojan).

A few trimming tasks on the round Plastic Mount for the PZ-480 was done to allow the Green Frame that holds the Dummy Engine flush against the firewall.

Someone please tell me what sort of tool I can use to cut into the Cowling as it is pretty thick and tough!...Continue Reading

To see the First Blog Post of this subject then, please go to:

UPDATE: (The KIT has been fully Assembled - FINISHED)

I have performed Weigh-In sessions and taken pictures of just the Dummy Engine "Hollow" Bust in two (2) configurations on the Digital Scale (oz.).

The first is including everything that came in the KIT and I assembled using and following 95% of the supplied instructions from Peter.

The other is leaving OUT the Metal Bolts & Nuts that came with the KIT and the Exhaust Pipe.
(Going to use Tie-Wraps to secure Engine Bust onto the Green three-point mount for weight savings!)

I have also included High Resolution "CLOSE-UP" Pictures of this KIT that was kindly shipped by Peter so, you can see the excellent results using the GORILLA "CLEAR" Glue. This Glue doesn't seem to have added any weight and the Title saying it is "CLEAR" is exactly that because you just can NOT see any residue of Glue anywhere!

Okay, the pictures showing what you have been waiting for (Sort of........).

Oh, as far as the mounting, I have a surprise in store and it will be my favorite thing I do with these models.

Stay Tuned!

A nice Gent by the name Peter from Germany has been dealing with 3D Printing and produced a scale 9-cylinder Engine Bust model that actually allows the Stock E-Flite 15 motor to go through the cavity of the Engine.

Details are at:

3D Files can be downloaded from:

Here's my comments about the preparation of the parts from the Frame Molds.

1. Instead of drilling and other tools per the instructions, I have used an angle hook Pick Tool that was very effective in the cleaning of the main Engine Housing.
2. The Cylinder Push Rods need careful handling so as not to lose any because one of mine was ejected and flew a few feet at a location that was easy to recover.
3. Otherwise the instructions are very very well written.
4. Instead of CA, I am using Gorilla "Clear" Glue and it has been with great results.


The Pick Tool did a super and fast, effective job in cleaning up the inside of the main Engine housing.
This is by far the best Engine Model that I have ever come across and the quality is very good for 3D printer.


I am having great results in using the Gorilla "CLEAR" Glue!

Does NOT leave any residue, pretty much fast cure (comparatively to others) and it is CLEAR and does not look like there is any glue what-so-ever.

The warning label says to watch out for fumes but, I don't smell...Continue Reading

Today was our RC Club Fun Fly at Moon Port Modelers RC Club in Titusville, Florida. Lots came to see the action and there was Lots of Action (Crashes)!

Of course this was during the Approach to the runway where two stationary poles where on either side of the Textile Runway and holding Party Ribbon material. Many just didn't pay attention to Lining Up their models and three Hit the Poles!

Well, I did pay attention and lined-UP perfectly in the middle of the Runway line and attempted to cut the Ribbon but, a very bad idea came to mine. I decided to come in Super Slow and with Gear Down and you guess it, the Gear did catch the Ribbon but, the model Stall as it was going too slow and crash landed at the Runway from about 5 Feet off the deck. Broke my model's Durafly 4-Blade Propeller and broke off Right Wing Tip clean off. I had a wooden Two Blade Prop (10 X 8) and used that and my Snorting Bull went up with Vengeance and flew again. Everyone applauded when it took off again.

One important NOTE on the selection of Propellers, that wooden 2-Blade 10 X 8 Glow prop was a Dog compared to the High Thrust Durafly 4-Blade propeller. I am searching as I type for two Spares and after that, I will be considering using the E-Flite 4-Blade. The 2-Blade just didn't have the CLIMB and I could not perform those crisp Cuban-8's with that 2-Blade. Well, at least it flew again for three flights with that 2-Blade!

I came with my Hobbico Super Star EP (3-Channel) modified...Continue Reading

I know that many have old GWS Slow Stick Models that have been stored perhaps as long as mine and it takes just a few minutes to test and test the electronics and Radio Gear to make sure ALL Systems work flawlessly.

In my case with this RED GWS Slow Stick, I found today that the No-Name Brand 20-AMP ESC had a hole in the Heat Shrink Material right over the FETs and also during testing by connecting a Battery and Transmitter it just did not want to come alive! This particular Slow Stick is on a BERG super narrow band 72-Mhz (Castle Creations Product) and coupled with my JR XP-7202 Synth Transmitter that is just Rock Solid. Well, after several connects and disconnects with the Battery -to- ESC connector I found a strange issue with it being completely active and then, it went dead after a few minutes handling the connector!

I took off the Tape for the Positive and Negative at the ESC Connector (once I had everything disconnected from the Battery) and found a very bad SOLDER Joint at the Negative post. Needless to say, I just went ahead and replaced this ESC with the Bullet Proof E-Flite 25-AMP ESC and like magic the model stayed active without any issue nor brown outs. This exercise made me create a new Memory Location for this Slow Stick and on Channel 31 so, not all was lost and it has it's own memory location on the Transmitter!

Additionally, I checked all linkages and foam hinges and they all passed with flying colors!

I had an opportunity super early this morning while the family was still asleep to work on at least one RED SLOW STICK with a BP Brushless motor, ESC and servos already installed, however, required some TLC and minor repairs.

This particular GWS Slow Stick had some modifications and RICHARD installed hollow Aluminum Rubber Band Securing Posts to allow for any size / shape rubber bands and not fear that they will come OFF during flight instead of just using the STOCK Plastic Nipples.

However, one section (Right Front Post plus Plastic Hardware) was observed to have been busted completely off and I had to improvise and repair. Luckily I have a good hardware collection of sorts and was able to fix the post by drilling baby drill on the top of the wing saddle and found a head bolt small enough with almost a flat head to fix and return this SLOW STICK in flying condition.

A few Pictures!

Since my buddy (Gerry) is retired he beat me to having the first operational SLOW STICK from the lot I found in my house last night!

Gerry really wants to go back to relaxing times and fly SLOW and LOW as he has a Grand Daughter (2 years old) that is transfixed with RC Airplanes!

I wished that I had the BLUE!

Two Slow Stick, I acquired from a good friend named RICHARD who moved away to Madison, WI.

Anyway, I found a brand new In-The-Box "YELLOW" Version Slow Stick, Slope Version (No Power System).
