This video was taken by Rafael Badillo on 11-10-21. Its subject is the maiden flight of Meister Fockewolf 190 A5 built by Ramon Medina and restored by Gonzalo Bures. The Maiden flight took place in Borinquen RC Club in Sabana Seca, Toa Baja, Puerto Rico. The club has an 800' asphalt runway in very good conditions.

The restoration took about 6 months and included replacement of powerplant to a 3W 70i, installation of new electriclal power sources, scheme change, repair of damaged areas , repainting, balancing and testing. Details of the restoration process and progress can be seen in my Blog in RCG. Shamefully, I omitted replacing the tires/wheels which were 12-15 years old Dubro and the foam was Gummy (like Gummy Bears) causing the plane to have drag on its roll. Since I had not had a 40lbd model before, did not judge the tires to be ready for replacement. Now I know better. New tires are ordered.

The model has a wingspan of 100",. Its powered by a 3W 70i rear carburator driving a Zinger 24X10 wooden prop. It has a 36 oz Dubro fuel tank which will provide fuel for an extended over 20 minute flight. Ignition is a CH Ignition powered by a LIFE 2.1K mah. The FW 190 is controlled thru my old faithfull Futaba 9C with a 9 channel PCM receiver and Hitec metal gear servos., nine of them in total. Elctrical power source is for the receiver main; 2 LIFE 3K mah in prallel connected to a backup NAM and a B/U LIFE 2.1kmah as battery back up with external LED to show if the...Continue Reading

Finally after a long restoration process, Schennewittchen is ready for her maiden. Friend Ricky Rivera took video of the FW 190 taxing to the runway to perform her maiden. In the video is Rafa Badillo who took the full video of the flight and will be shared with you when its ready in youtube.

In the meantime, the maiden was succesfull. Everything went fine right up to touchdown. Been cheap is not good in this hobby nor any other. I fixed and replaced many iyems but kept the main tires which are 15 years old. On touch down, this "Gummy Bear" tires prevented the model from maintaining its forward speed and worked as breaks. The FW 190 made a nose over due to the fast loss of forward speed. No damage occurred. Not even the wood prop was broken.

Will install new tires that will roll easily for the 2nd flight.

After this engine test, the engine started to give problems. In this startup process, the engine had to be above half throttle to start. After troubleshooting, replacing the muffler to have access to the idle needle and opening it a bit, the engine continued with the same fault. Would not start at idle or with throttle below half travel.
After a while, it stopped starting at all. Fuel was getting to the combustion chamber. As a matter of fact it was very wet with gas. Checked the spark and it was very weak. The battery voltage was perfect. Eliminated the ignition switch to insure that the juice got directly to the ignition.
Just purchased a new CH ignition and will try it next week. Hope that was the problem.

Have had this Saitta produced ME 163B model since 2014. Has more than 130 flites. Is one of my favorite models to fly. Its looks, flying procedure, takeoff, flite and landing is scale and very unique. It draws a lot of attention at the flying field.

Futaba 9C radio, Rabbit 100 Jet Central turbine. Very aereobatic and docile at the same time. Will have extended 7+ minute flights. # fuel tanks totalling 96 oz of fuel. I use diesel fuel which actually provides more punch than jet fuel even thou it weights some more.

Last flying session on Sept 2021. Video attached

Have had this Great Planes DR-1 since sometime around 2005. Has had many many flights and its body shows it. The Monokote is patch up with Monokote and USPS tape in many places.

The DR-1 still flies and does it very well. As a matter of fact this model does the most insane spins I have ever seen . I will start spinning it at an altitude of 300' and breakout of the spin at around 50'. The 250' spin treck takes around 10 - 15 seconds. The spin rate is awesome at about a revolution every half to 3/4 of a second. The angle very shallow, almost a flat spin.

The DR-1 is powered by a Saito 90 4 stroke with a 14X8 prop. It has a very nice sound to it and it idles at very low revolutions.

The Dr-1 is not an easy plane to fly thou. You have to be on top of it all thru the flight. It dislikes crosswinds and will track perfectly with wind not been more 25 degrees of the runway center. Surprisingly it is usually docile at landings even with its very narrow landing gear.

Just flew it last Wednesday 10/13/21 after a layover of around 2 years. Did have to work on the engine to loosen the throtte barrel that sticks with the old gummy castor oil. Otherwise, it started on the 1st try, adjusted high speed needle and idled perfectly.

Will do a restorer in the future not using monokote but silk span and sanding sealer. This will make look more real and high don't particulary like ironong on materials specially Monokote.

Will post once I start the restoration.

I have just embarked in the restoration of a Ziroli FW190 built by Master Builder, Ramon Medina some 20 years ago. Ramon is one of the three best Puertorican model builders I have had the pleasure to know.

Robert Tanner, a friend and RC club member of ours, asked Ramon to please build this model for him. He choose Ramon for his extraordinary building skills, patience and realism in his projects.

The model throughout the years passed thru the hands of Robert, Ramon himself and Wilfredo Morales. I always liked Ramon's FW 190 and asked him if he ever needed a foster home for it, I would love to have it. Finally the model is with me and I plan to restore it to its original beauty.

When I got the model it had a Quadra 75, a very good engine but not with the performance of an alternate power plant I had in moth balls, a 3W 70i. This is a very powerful engine with a higher performance than the Quadra.

I started the restoration by removing the Quadra, installing the 3W and preparing the cowling. The model lacked an air dam to channel the incoming air to the required areas inside the cowling. I prepared and installed one. Painted the cowling and made the squadron shields. The engine ignition was installed in an area were the airflow would cool it. The ignition power switch was installed in an opening available in the cowling. Before ending this phase, insured the system was working with a spark in the plug. I had to make a choke activation mechanism since the 3W is a rear...Continue Reading

"Chona" is a Ziroli 100" A1 Skyraider scale model. The Ziroli kit was built by Ramon Medina, one of the best model builders in Puerto Rico. The model was built around 2015. Since Ramon built it, I shared with him that if he ever sold it, I would be the 1st in line. I purchased the model in 2017, some months before Hurricane Maria struck Puerto Rico.

Ramon is not a fan of installing any external payload in his models. Even thou he had made the payload pylons and missiles for the A1 Skyraider to carry, he never installed them. This is one of the things I added to the model. I added the payload pylons and installed E-flite payload releases. I made 2 droppable Napalm bombs for those two pylons. I also finished and installed the missiles and rocket tubes in the remaining wing pylons.

In 2017 I gave the Skyraider my maiden flight, (it had been flown multiple times before by Ramon). The model flew perfectly. I did experience scary moments when prior to the 1st landing, the main landings didn't fully extend themselves. Ramon, who was standing right next to me, told me that this was normal. Ramon explained that the landing gears and big 5.5" wheels created such drag with the airflow that the gear would not fully extend itself unless you slow the model significantly. Taking this measure, the retracts would be able to win over the airflow and fully extend themselves. This really gave a goosy feeling since I was not going fast when I attempted to extend the...Continue Reading

Was asked to create a blog with the A6M2 Zero video only. Here it is:

Zero DLE 55cc (1 min 41 sec)

Posted by GonzoBorinquen | Dec 03, 2020 @ 02:26 PM | 13,271 Views
This A6M2 Zero is an ESM 88" kit. It was built some 10 years ago and is still in excellent conditions and flies often. The ESM kit is no longer available. ESM is no longer distributed in the US or been produced. Spare parts are very hard to find if at all. So fly them with very much care.

The A6M2 Zero is powered by a 55 DLE rear exhaust gas engine with a 22X10 prop. Ignition is powered by a LIFE 2S 2K mah. An air dam with a radial engine was installed in order to divert air flow to the cylinder head as well as to cool the ignition. The Zero is very fast with the DLE 55 RE. Its normal cruising speed it’s with a throttle input of 1/3 throttle. Tis throttle position provides for very scale flights. At high throttle, the model has an excellent vertical performance.

The A6M2 Zero It is controlled by my faithful Futaba C nine channel in MHz frequency. It has 2 LIFE 2S 3Kmah batteries for main and B/U connected to the receiver thru a battery back up by RAM. The model has installed a total of 11 servos.; 2 servos Ailerons, 1 very high torque servo for elevator, 1 servo Throttle, 1 high torque servo Rudder, 1 servo for tail wheel steering, 2 servos Flaps, 1 servo retracts main, 1 high torque retract servo for tail wheel, 1 mini servo tail wheel cover.

The main gear retracts are Sierra and tail wheel uses a mechanical retract. The air system is redundant with two bottles and one way controller in the event one tank bleeds the other does not lose the pressure too.

I have always liked the looks and flying characteristics of the Zero, especially the A6M2.
In 1988 I built the Top Flite Golden Edition Zero. The 1st Golden Edition was composed of various scale models including: F4U Corsair, P40, P51 Mustang both D and razor back, P47, A6M2 Zero, P38 and some I do not recall. I still have the model and still flies with the original engine and radio. At least one flying day I take it to our club and fly it. Only the batteries have been upgraded to LIFE 2S 2Kmah.
The Zero was my 3rd RC model ever. I decided to build mine using Saburo Sakai’s model as pattern. It is a 60” wings span model. The Top Flite Zero, is a fully planked model, both wing and fuselage and with very little area inside the model for equipment. Been my 3rd building experience and the 2nd scale model, the first was a Piper Cub clipped wing, I went slow in the construction learning a lot in the process. I decided to construct the Navy version so gray it was.
The model is powered by an OS 90 glow engine with a Pitt’s special muffler turning a 15 X 8 prop. I used an all metal, one piece engine mount to mount the engine made by Sullivan, I think. The model was design for a 60, but I needed weight to balance the short nose fighter and obtain the CG. I also built an air dam for cooling and mounted on it a radial engine mockup. All this nose weight was welcomed. Better than dead lead.
The model is guided by my C 9 channel Futaba radio, still in the old MHz frequency. It...Continue Reading

Built this ESM ME 110 Zestorer kit some years ago, probably 12 years. Loved the looks of the German Fighter, did not know much at the time of its history and or its performance.

After purchasing the kit and various books on the fighter, realized its performance was mediocre at best. Its agility was very poor, the acceleration about the same. It only had its endurance, range, high end speed and firepower going for it.
I realized I had fallen in love with the looks of a flying turkey. I had invested a pretty good amount of $$ on this model and looked for options. Searching in the all the books I had purchased, I found another obscure and unknown use given to the ME 110. This utilization is not known to most, the night fighter strand.

I purchased a couple of books on this strand of the ME 119 history and found the flying eagle I was visualized building. The ME 110 Night fighter was one of the best if not the best night fighter of its time. Armed with 30 mm cannons firing to the front, two more 30 mm cannons firing thru the canopy on a vertical axis right into the belly of the bomber and its machine guns facing the rear, it was a formidable hunter. It also had night vision with its radar which guided the pilot to its victims. Its record sustains that claim and British night raids suffered from its superior performance and tactics. I decided too built the ME 110 Zestorer night fighter and the results were excellent.

The model has a 95" of wingspan, length of 78"...Continue Reading

Pica FW 190 D9 scale model built in 1969 by Rafael Sacarelo. Rafael has been a Control line and RC modeler almost all of his long live. Rafa is today, 2020 88 years young and still flies’ models almost every weekend. I have told Rafa many times, “When I grow up I want to be like you". Rafa still flies his biplanes and has a jewel of a P47 covered in metal (aluminum) panels fully scale. This model waits for the perfect day for its maiden flight.

The Pica FW 190 D9 was original built in 1969 and it was ahead of its times. It had sliding canopy, feature not common in those times. It was originally powered by an OS 60 and was controlled by a Futaba utilizing 5 channels; Aileron, Elevator, Throttle, Rudder and retractable gear. It was flown in Miñi Miñi RC club in Canovanas Puerto Rico. The model competed in various scale contests and had an illustrious career.
Sometime in the 80's, Rafa stored the model. It was not flown for thirty years until in 2017 Rafael pull it out of retirement and gave to me to restore and fly again. I did it first restoration in 2017 and powered it an OS 1.08. Not much was done to the structure which seemed in good shape. The model had successful three flights in 2017. On its last flight, one of the gear structural beam failed. The damage was minimum and easily repaired. But upon inspection I realized the wing balsa was very very dried out and easily broken. That was what had happened to the gear beam. I decided not to risk the model. Set it aside and do a more profound structural inspection and restoration.

Pictures of the FW 190 D9 after 1st restoration.

Heinkel 162 Salamander WWII turbine model. It took me seven months to build the model. The kit was produced by Bruce Sanders Century Jet Models. The kit is no longer in production. The kit is a very complete short kit. All wood except wing planking is included. Main kit parts are a fiberglass fuselage with plywood bulkheads and foam core wings.
Have not given the Salamander its maiden flight yet even thou I has been ready to fly for a while. Will publish how it went with the maiden flight when it takes place. April 2020 is the set date for the maiden flight.

The design of the full scale HE 162 took four months and 1st prototype was shortly available after that. The plane went thru a very short trial period with many retrofits installed after almost every test flight. Been in production in late 1944 and with many materials in short supply, the creation of the 1st squadron itself was a major task.

The model is controlled by a Futaba 9C radio, powered by Jet Central Rabbit 100 SP, Century Jets retracts, Xicoy sequencer to coordinate landing gear with gear doors and Jettronics variable low-loss braking system. Controlled by 11 servos. Controlled by Futaba are two servos in Ailerons, two servos in Flaps mixed with elevator switchable, one servo on each Elevator, one servo on each rudder, two servos controlled by the Xicoy sequencer for air valves ne for retracts another for gear doors and one servo for steering.

Fuel load is 124 oz. distributed by in four tanks in...Continue Reading

Horten 229 V3 WWII flying wing model. It took me a year to build the model. The kit is produced by Gary Hethcoat http://www.wingsontheweb.com/. Everything about the kit is class #1. Fiberglass center section with plywood bulkheads and built up balsa wings.

Maiden flight took place on 2/29/2020 at Borinquen RC Club in Toa Baja, Puerto Rico. It flew flawlessly with only minor trimming, 2 clicks left aileron and 1 click up. It flew very Stable no bad habits in the air. Its silhouette is very peculiar, but looks commanding and draws all the attention. The design does place a lot of its weight in the nose gear and requires attention on takeoff and landing.

A revolutionary design testament to the Horten brother’s innovative design. Recognition to Gary’s aeromodelling knowledge scaling down a very complicated model.

The model is controlled by a Futaba T14SG radio, powered by two JP 70mm counter rotating EDF’s, two JP 100 A ESC, two 6S 6200 ma in parallel, JP electric landing gear with sequential gear doors and brakes. Controlled by 13 servos. Controlled by Futaba are Elevons, Mid Flaps mixed with elevator switchable and also for speed brakes, inner flaps for speed brakes (crow), steering, drag Rudders for jaw and throttle.

The model spans 82” has 1277 sq. inches of wing area, weighted fully loaded 17 lbs....Continue Reading

My 1st turbine plane....what a way to start.

In 2014, a friend of mine gave me a Joe Saitta ME 163B that had been handed down thru many hands since 1999. The model had never been started, it was a propeller driven, 82", ME 163B short kit. It still had the original plans, Fiberglass fuselage and some of the ribs and bulkheads. The rest had been lost thru time.

I contacted Joe Saitta thru email. He was very supportive and indicated that things had changed since 1999, now his model was turbine powered. The fuselage was the same as well as the wings, but the bulkheads and other items in the fuselage guts had changed. He prepared an upgrade kit for me and I was ready to start.

I had been building models for some decades, so this was not an issue. Turbines was another thing, I had no knowledge of them. Nor was I AMA turbine certified. A good friend of mine, Juan Garcia, became my mentor and taught me all I had to know on this power plants and models.

I finished the model in a few months. Since this plane lands on a skid, landing gear is detached on takeoff. I prepared an aluminum skid that follows the external contour of the fuselage. This will protect the belly of the plane upon landing in grass field. The landing gear/dolly was made of wood and aluminum and version 1.5 was the perfect one which I have been using the past five years. The first four versions had each a different flaw which required modification. Takeoff dolly release can be very tough on the dolly....Continue Reading
