@ 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!

Hello good people!

As the title says, this is perhaps the Finalized Summary on the:

3D Printed 9-Cylinder Radial Engine & E-Flite AT-6 Texan with PZ 480.

I believe that I did a good job providing the Summary over at RCUniverse and you all can read up on it at:

Here's the measurements and so sorry some are in "INCHES" because we are so used to dealing with that scale!

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!

Here is the...Continue Reading

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
