I did not know much about Merco engines, except that I recalled the brand name from being in the hobby all of my adult life. I did not even know that they were made in England. Until recently, that is.

I had been thinking of getting a Merco, mostly because it seemed to be a somewhat obscure brand of engine and I wanted one for my collection. How wrong I was! Thanks to the website Sceptre Flight, which has dozens of old engine reviews from the long gone print magazines, I learned just how much the Merco was revered back in the day, and what a world champion caliber competition engine it really was.

But before I had read any of those old articles, I had purchased from the RCG classifieds, a well used and castor oil coated Merco .61 Mark I. I intended to tear it down, and rebuild it.

This particular engine was frozen solid like a rock! The old, dried castor oil had welded every part to each other. It took copious amounts of heat to get anything to loosen up so that I could disassemble something as simple as the back plate. To get the cylinder out I had to machine a drift from bronze, and use a lead hammer while wearing thick leather gloves to protect my hands from the searing heat due to having to super heat the crankcase to loosen up the burnt on, dried out castor oil residue.

Once I had the engine completely disassembled, I soaked the parts in an ultrasonic cleaner with a diluted cleaner concentrate. That took care of most of the old castor oil but some of the parts

This is my 2nd Flyzone Beaver. This is the Island Wings version, a much prettier livery. This one I have made into a float plane. My other Beaver was strictly on conventional landing gear and tundra tires.

This one I coated with Minwax polycrylic. I also added the "steps" to the float supports. And I detailed the faux radial engine. I also added an electronic switch so that I can turn the navigation lights off if I wish.

Maiden voyage and flight soon.

This is a "Rocket Victor .45" from 1945. It was manufactured by the May Motor Company. George May was the proprietor and designer.

It was probably a "budget" motor back in the day as it is made from low cost materials and methods. Such as, a stamped steel connecting rod, three piece stamped steel crankshaft, steel piston with a sheet metal baffle bolted to the top. It has no bushings, let alone bearings. The needle valve is aluminum with what looks like a tapered nail. But, it is cool looking! The exhaust stack is classic! And the points adjusting lever looks like an old fashioned gearshifter.

This engine had a lot of field repairs done to it. Most of the screws are not original. There was a hole drilled into the top of the fuel tank and later plugged and epoxy glue applied. There was some epoxy glue on the backplate too. Two of the cylinder hold down screw holes are stripped and drilled out and larger screws and nuts in place.

I disassembled it and cleaned all the parts. The back plate has a sheet metal rotor staked to a drum and it broke off because the drum was stuck inside the back plate with dried castor oil. I repaired it, It needs a spark plug. In the mean time it has a glow plug installed. It has good compression and pops nicely when flipped over.

I just happened to have a vintage, custom made motor mount that I got years ago. Never knew what it was designed for. Well, it fits the Rocket like it was made for it. Coincidence?

It's

This model is specified to us a 4S battery. I did the maiden on a 3S because I wanted to see if it would be doable. And it was. It had enough power and flew on the wing, very scale like.

I used the same battery yesterday, fully charged. However when I got to the runway a 3D guy asked if I could wait while he did his routine. So I waited for around 15 minutes until he landed. My plane was "on" but not using any servos.

I took off and did not even make a second lap around the field before it had lost so much power it could not stay in the air and crashed into the tall weeds just short of the runway. No damage thankfully because the weeds are fresh and soft from all the recent rains.

I then inserted my second battery, the same type and size as the other one. This time it flew as expected, and because the other battery spooked me I only flew it for a few minutes. But when I got back to the pits the cells were still over 4 volts each so I could have gone longer.

But I have proved my point to myself. I think in the future I will use 4S batteries.

I flew this guy several years ago. The engine would not idle and it was a bit of a pain. Recently I ran about a half gallon of fuel through the engine, trying to get it more broken in, It idles a little lower, but not enough. And it dies when idling. PITA. So I just started it on the runway and let it go from there. Flys really nicely and the motor does sound really good.

Redcat recently came out with a very scale looking IH Scout II body mounted on an all new chassis. It is a little larger than the Gen 7 Everest model they have.

This new Gen 8 comes with molded light buckets so it is easy to install headlight and tail light LED's.

It is a very impressive model at a very reasonable price.

After nearly 5 years of ownership and many flights, I lost my Flyzone DH-2 Beaver to the RC demons on Wed 11-27-2018.

I was using a new Spektrum DX8 Gen 2 transmitter, with the same receiver that had always worked on my DX7s transmitter. Don't know what went wrong, but it acted like it went out of radio range and went into failsafe mode.

The fuselage is too damaged to repair. Firewall is broken, and it was molded inside the foam when the fuselage was made, so no easy way to replace it. The landing gear supports are twisted and broken out. The landing gear plate on one of them is all bent out of shape. The motor mount is bent severely. I just decided to pull the electronics out and call it a done deal.

I bought a 1400mm P-40B made by FMS and it arrived about a week ago. I started assembling it a few days ago and did some detail painting to it.

It has many plastic pieces that are molded in color but they do not match the paint. I wanted all the pieces to match so I took the elevator assembly to Lowes to have the three colors computer matched and get sample bottles of each paint. As it turns out only the green was a perfect match. The gray was too dark and the olive drab was just totally wrong.

At first I painted the plastic pieces with the gray paint, but it really bugged me that they were darker. So I ended up mixing some paint myself to get a better match. Not perfect but a lot closer. I also tried to mix up some of the olive drab brown but could not get a match. However I came up with something better than the maroon looking stuff that Lowes made.

I also had Lowes make up some zinc chromate green for me and I used that inside the wheel wells and flaps.

I painted the gear doors and inside the wheel wells. I painted over the clear plastic surrounds on the navigation lights. I painted the nav light lens' on the vertical fin. I painted the pitot tube. I painted the exhaust stacks. I airbrushed some exhaust smoke stains on the side of the fuselage. I painted the spinner. I softened the hard edge of the green camo around the cockpit and canopy. I painted the machine gun barrels flat black. And I made decals for the hub caps.

When I had installed the radio I

Anyone remember these?

Mine broke down 10 years ago. I let someone drive it and they were hammering on it pretty good. I thought the diff had blown. I parked it in my shed and left it. Decided a couple of weeks ago to try to get it going again. Turned out one of the motor mount brackets sheared in half. I made a new bracket. Cleaned it up and was ready to try to start it. Pressed on the primer bulb and it crumbled from old age. I found new carbs on eBay for $15 shipped. Got the carb installed and she fired right up. But my linkage was catywampus at first. Got it adjusted and drove a couple laps in the backyard.

My Beagle likes to chase RC cars. She has never seen such a large RC car as this! lol...

This little park flyer is very nicely molded. It is outstanding in its scale outline. It is very quick to assemble too.

I did the maiden flight on a windy day, and it did get blown about a little but it was still fun to fly. I think it would be great in an actual small park, surrounded by trees that act as a wind break.

Just finished assembling my Stinson. I did the flap mod first before anything else. With the reputation Parkzone has, I am a little annoyed by some of the things on this model. Like the wing strut attachments are extremely cheesy. The servo wires are to short, and the battery connector is WAY too short. I will have to make a permanent extension for the battery connector as it is nearly impossible to get a battery plugged in and I do not want to damage the model trying repeatedly.

Other than that, the model looks very attractive in its livery and I am looking forward to the maiden flight.

I started assembling my Fly Baby today. This is made by Taft Hobby. It was also sold by Hobby King in a blue color scheme. It's a nice looking scale model.

There were a few minor mistakes from the factory. The first one was the hardware. It was supposed to come with several different lengths and sizes of sheet metal screws, but they were all identical. So I drilled and tapped for 3mm screws and used them instead. Another issue was the rudder control horn. It was not glued in properly and came out as soon as it was touched. I re-glued it. And then there is a large plastic piece that supports the landing gear. It also connects the two wing halves. It broke off as soon as I was working around it, again for lack of glue. It had only one little dot of glue for a rather large piece.

Other than those issues the assembly is pretty easy and fast. I still have to string the wire bracing and install my Rx.

I recently installed a Heli-Max tail rotor gyro in a 2WD Indy car and it made a night and day difference.

So I bought another heli tail rotor gyro, this time it is an Assan brand. And I have installed it in my Raider XL buggy.

The wiring and connectors were a very tight squeeze under the receiver box but I managed to cram them in there!

So I have decided to also get this Overdrive ST set up and will be playing with it too. Why not?

This has also been assembled partly and on display since around 2003, don't remember exactly.

Amazingly the alkaline batteries still are holding a charge and powered up the electronics. The expiration date on them is 2004!

This is a cool stadium truck. 4WD, 2-speed trans, forward and reverse, .17 engine, oil shocks, blue anodized aluminum parts.

It has a Futaba AM radio on 27Mhz. Old skool for sure!

I intend to get it running and drive it around easily, I won't be beating on these old vehicles like back in the day. I plan to keep them in nice shape.

I bought this XTM Baja 4WD truck in February 2003. I changed the wheels to some rally types and added a Subaru body, then put it on a shelf for display. It has never been used. No fuel, no batteries in the radio, even the antenna was not unraveled, lol.

Well, the tires are now flat spotted but I think they will get round again. I have made adjustments to the suspension and steering because from the factory it was off, glued the tires, checked all screws for tightness, and adjusted the shock pre-load.

I will now balance the wheels/tires, and then the engine will start its break-in process.

I have decided to stay old skool with the stock Hitec 75Mhz radio system.

It was cool going through the original box, and manuals, and time warping back 15 years to when this was a current production vehicle sold by Hobby Shack.

It's just another one of my collection of glow fuel engine powered cars and trucks I have and want to get running.
