Hello good people,

Just sharing some experience with swapping over a good frontal bearing from a spare motor to my favorite motor that developed an issue with it's Frontal Motor Bearing. The spare motor was actually on this recently acquired Park Zone T-28 Trojan with retracts and noticed that my Batteries were coming a little warm, usually they come down luke warm. Please NOTE that the motor that came with this recently acquired Trojan did NOT have the Bad Frontal Motor Bearing issue.

Took apart both motors and with a little planning and caution, the parts were secured carefully. Both motor frontal bearings were taken out by lightly tapping them out with a wooded dowel and tested the bad bearing on the rotation bell of one motor and sure enough it made a rattle of a noise. (Video).

Swapped the good frontal bearing to my favorite (Stator) Park Zone 480 motor that always gives good performance and low AMP draw using the Master Airscrew 10 X 7 X 3. Static testing after putting together the flight motor yielded very good power:

EDIT: I found a good article about Brushless Motors at:

FULL THROTTLE: 183 WATTs / 17.3 AMPs / 10.7 Volts

On Tuesday (07-07-2020), I flew this recently acquired PZ Trojan from a local friend and it performed very well with very good airspeed but, again the batteries seemed to come down a little warmer than expected. I do hope that using my favorite Stator (Motor) would give better...Continue Reading

My Lord, it has been almost 10 long years and my Slow Stick-X using GWS Slow Stick Parts has survived!

I recently flew it about a week ago (during the weekend) at my RC Club using a HIMAX Inrunner Brushless with the HIMAX gearbox. The issue was I could not keep the propeller on the output gearbox shaft. Perhaps I needed one more additional washer and use sand paper on that Spur Gear Output shaft, nonetheless, I went back to basics as I wanted a power system that gave it respectable airspeed but, with LONG Flight Times.

Therefore, I came to a complete circle of sorts and found my original ASTRO FLIGHT mightly mirco 010 14-turn inrunner brushless and found a GWS EPS-300/350 gearbox and installed the GWS "B" Spur gear which makes 4.43:1 reduction.

Placed a GWS Slow Flyer (Orange Propeller) EP9070 which is a 9 X 7 propeller.

Performed numerous repairs on the wing and from a previous crash that occurred over 10 years ago and recorded right here somewhere under the Handle "Guapoman2000."

Okay, today it flew super early morning over at my RC Club and what a delight! It satisfied all requirements to the T. Very good airspeed and just an awesome almost 9 minutes and the Thunder Power 3-Cell, 1350mAH, 25C still had 11.98 Volts after the flight from a fully charged 12.5Volts state.

I believe that I could have flown for an additional 5 minutes with mix throttle and would have reached around 11.6 Volts from the Battery pack. Next time I will gradually increase flight times, land and measure then, repeat after fully charge and fly a little longer etc... etc...

Thanks for watching!

Quiet Time of Remembrance

A rather quiet time for me was this past May 11th, as it marks the last time my assigned Space Shuttle was powered down for the Last Time.

This date marks a significant time when Space Shuttle Endeavor (Tail number OV-105) was powered down for it's final time on May 11th, 2011. This marked 19 years of service and this magnificent spacecraft managed to accumulate more than 123 million miles and over 25 flights, far few for it's projected service life design.

No matter what you think about the Space Shuttle era or the overall program, to me it was my blood, sweat and tears. Although it may have not contributed to my divorce directly it certainly had an impact because of the hours (Shift work) and travel I was asked to support this program. After so many years being Divorce from the mother of my two wonderful daughters, I believe they have grown to understand my plight of my selection of work as an Aerospace Engineer during this time period and supporting the Space Shuttle Program.

So, now we come to terms today. A soft whisper while half asleep at my keyboard saying it was worth it. To see such a magnificent vehicle like the Space Shuttle to rise up from a sketch during the late 1970's and to become one of the robust space vehicles known to man. Most especially being part of the initial efforts to bring Space Shuttle Endeavor to active duty as a viable spacecraft.

Yes, tragically, we lost two (2) vehicle, the Challenger (Tail Number OV-99)...Continue Reading

Today at our Fun Fly over at Moon Port Modelers RC Club, Titusville, Florida .... I won the Model Raffle and guess what it was????

Yes! You guessed it, the Great Planes G-44 Widgeon!

It came Ready to Fly - Receiver Ready!!

Anyone has suggestions?

I was totally shocked on how much they are asking for a new one in the BOX!

Hello good people!

Reporting in to inform that I was totally successful in re-maiden my Hangar9 F4U-1D 50 size Corsair Electric!
Was rather windy but this almost 8-pound RC model was not affected in the least! Wind was straight down the runway from the South and it helped in landings as this model has no flaps and really doesn’t need them.

For those that have NOT been following my Repair Adventures on this model then, here are the links to follow along:




All it required was two clicks of down trim!

The F4U Corsair was flown with the 5-Cell, 4,000mAH 30C Turnigy and two 4-Cell, 4000mAH 30C GForce Elite Series Lithium Polymers!

It was a delightful Wednesday morning and stayed about 3 hours!
EDIT: 05-21-2020

Hello again!

Providing some Flight Characteristics using the 4-Cell versus the 5-Cell, 4,000mAH 30C Lithium Polymer battery packs.

The typical flight duration was 6 minutes each flight and the attached pictures show the Post "Resting Voltage" of each Battery pack after 6 minute flight.

The 4-Cell packs provided a lighter feel of the model and was comfortable with slower flight and maneuvers while at a slower flight routine....Continue Reading

Hello good people!

Was super lucky and acquired a super nice and Brand New (In-the-Box) Hangar9 F22 Raptor PTS. This is the Gray version and it came in record time all the way from White Rock, New Mexico via FEDEX Ground and came one day earlier (on a Saturday)!

This one will be Electric as well!

Hello good people!

Happy Friday!

After a little over two (2) weeks, off and on, in-between work, home and family obligations I have finally got my beloved Hangar9 F4U-1D 50-size Corsair Electric powered RC Model all flight worthy after extensive checks and verification of structure, covering and control surfaces plus retract function. Here's the Video:

Hangar9 F4U 1D 50 Size Post Right Wing Repairs and Electric Motor Box Repairs 05 08 2020 (2 min 12 sec)

Okay, good people! Decided to keep working on my beloved (discontinued) Hangar9 F4U-1D 50-size Electric and started on the damages on the FUSE which thankfully were just Electric Motor Box damages during the one year ago crash contact with the Right Wing Assembly and that ugly tree on final approach.

As you will see in the following pictures, the FUSE really came out great during that crash (This is a very strong model).

Soon I will installed the Master Airscrew 3-Blade Propeller (13 X 8 X 3) and run up the Model Motors AXI 4120/18 brushless....Continue Reading

Hello good people!

One year ago my beloved Hangar9 F4U-1D Corsair 50 size hit the tree on the North side of the field where most of the trees are located. Fortunately the model landed after spinning for several rotations on its mains without any further damage except the right 1/4 end wing section.

Got too close on approach! This is a super strong model. The right tip wing section got ripped clean off. I have finally repaired it nice and slowly. Ribs that are cracked first and glued in re-enforcement ribs (custom cut from scratch) and repaired (reconstructed) the twin spars etc...etc... yes, sheeting was replaced last.

If I would have taken off the crushed / cracked balsa sheeting first, I would have never would been able to repair as the remaining Ribs were cracked and fragile. Had to maintain the stock / remaining Ribs in order to reconstruct this Right wing section.

Another TIP "is" make sure you get whatever Rib section to allow for future Sheeting to be able to sit flush with the remaining undamaged sheeting!

I used Gorilla Wood Glue (White) and Elmer's Wood Filler (Natural) for filling small holes and slight imperfections.

With the exception of some nicks on the edge of Right Wing Aileron and other small imperfections, I truly believe that this is way better than what I anticipated. She looks great and at least I will still have the brand new in-the-box ARF for that complete disaster crash and not a minor clean break of the right wing...Continue Reading

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.

High Res Pics!

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!
