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).

Pictures of the reconstruction / repairs of the Electric Motor box with comments.

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!

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!
