How do you maintain focus on a long building project? Flying and family? There are a number of opportunities that come up during the year:

1. Fly, crash, and repair. This can lead to a shelf full of damaged and almost-ready-to-fly tweak jobs. Some guys keep wrecked foamies in the trunk or van, but these are hard to see adding up.

2. The Long Building Slog -- a complex building project that just won't quit. I'm slugging it out with a Nakajima B5N2 Kate 1/9 scale. I don't have anyone to blame but myself. And I've also begun plans for a Seabear L-72, but that's hit or miss.

3. God, family, job, and friends -- these are huge life priorities. Our daughter bought a house in Nashville this summer and has required lots of travel time. Then you know the drill being active in my church, married to a wonderful wife (40 years! Woohoo!) and a father turning 91 soon, having an incredible job, and friends. And I'm not even going into ballgames that I occasionally catch. At least I can watch them on my phone while I'm at my workbench.

4. Good causes -- I've recently joined the Fellowship of Christian Modelers (www.fcmodelers.com) and have been planning how to man a booth at a competition. This is a good national club that offers prayer and support as well as a newsletter.

5. Plastic models -- I try to make a plastic model of the planes I plan to build. I joined a local hobby club and I keep winning plastic planes. I have taken a break from building RC to build a 1/48...Continue Reading

One of my favorite WW2 stories came from the end of the Battle of Saipan (the D-day of the Pacific). After 240 American planes had been launched in late afternoon to find the Japanese fleet, they had a long return flight back to their aircraft carriers.

Then the sun set.

Many planes ran out of fuel and had to ditch into a dark sea. All the pilots were desperate.

Then several destroyers steamed ahead of the fleet to meet them. They were instructed to break all wartime protocol and turn on brilliant spotlights that pointed the way to the carriers.

The pilots saw the lights pointing home. 99 planes and 46 crew members didn't make it home that night, but the others found their way thanks to the spotlights.

Jesus said for His followers to be the "light of the world." We must keep pointing the only way Home through Jesus.

Just a quick report on finishing the 68" wingspan of my 1/9 scale Nakajima B5N2 "Kate" from scratch and my own plans. It has a .60 motor.
The wing took 60 hours and about eight weeks through the summer due largely to working on itmaybe 8 hours each week and having a vacation in there and a business trip, too.

Changes from the original plans:
1. Plastic horns were fabricated from old credit cards and an ID plastic card. These were wedged between hard balsa aileron rib ends.
2. The wing tie-downs were close to the plans, but bigger. Once I found the 1/4"-20X1" nylon bolts at Lowes, then I could see the original perspective was too small.
3. The servos I bought were huge compared to what I had originally planned. I had to reposition everything. And worst for me, I had to relocate the holes in the 1/8" thick light ply hatches. I also decided to epoxy the servos to the hatches. (I covered them with packing tape before gluing.)
4. The tongue for the wing to the fuse had to be redesigned since I'm keeping a central set of ribs to strengthen the wings.
5. The 8 degree dihedral on the wings was difficult to match left and right. I am within about 1/16" of an inch matching wing height.

One of the other slow-downs is that I'm trying to correct the plans as I go. At least every other week, I jump on the electronic version of the plans (done in PowerPoint) and make some tweak.

Building a plane from scratch is much more difficult...Continue Reading

After five months building a Nakajima B5N2 "Kate," I think I'm about halfway in for me. I have a full-time job, but the weather has been really lousy in Ohio and it provides more bench time. I try to work at least an hour each night and about three to four hours on the weekend.

Here are some insights:
1. Reality bites: This build is the first using my own plans and boy am I humbled. It is so easy to draw plans into software. But in the 3D real world, a polyhedral wing that has 8 degrees dihedral on the outer sections has to bring reality into play at some point. The great news is that I am really good at admitting my mistakes and re-doing a rib here and former there and updating my plans.

2. Measure: I've joked that I measure twice, go to bed, wait another day, measure again, and then cut once, then sand for fit. I don't think I'd be a very good carpenter given my skills at mitering joints. But I've done some daring-do with these plans. The LE starts off at 3/4" wide in the middle and taper at the dihedral breaks down to 1/2". If you've built wings, you know that I am way past the point of sanity here. The good news? The 64" WS wings are level and the wingtips rise just right to hit my 4" mark. Okay, one does. The other is 1/8" and I can sleep at night.

3. It takes Perseverance: Making changes, creating a mess, coming back and seeing a glued rib leaning to one side, and other forms of modeling mayhem may continue to plague a...Continue Reading

My wife and visited the National Air Force Museum in Dayton, Oh. When making a scale Warbird model, there’s no place better. I’ve visited there for a P-51B and an F-15B.

There are no intact WW2-era Nakajima B5N2 Kates to view, so I got photos of the Zero and George. There were details on these planes that will transpose to my scale model: thin window frames and fabric on control surfaces for starters.

Here are some photos....Continue Reading

It’s tough to say when I begin a new build! I dream it out for quite a while. I have to budget. Research can be fun, but laborious at times. And this time I developed my own plans. This project is electric and from scratch as much as possible.

I have a build log underway. See it here:

When I developed the plans for a Nakajima B5N2, it took months. I actually got burned out on it last November and built another plane.

Now, I’m ready. Here’s some progress to date in photos....Continue Reading

Completed a 1/48 Scale Revell T-6G Texan. I got this 1991 kit for $6.00 at an estate sale last summer.

It is to honor Russell O'Quinn, God's test pilot. Russ learned how to fly much earlier, but he had to take lessons in a plane just like this at Hondo AFB west of San Antonio, Texas. I weathered mine by griming it up a bit because in 1949, dirt and dust was a constant there. I do plastic models so that one day if and when I make an RC version, I have a good resource for reference.

Russ went on to test and even design jets for the USAF. His testimony is outstanding! I can highly recommend this recording:

Today it was great to get the proper screws in the mail and bolt the rings in place. She looks good too and bottom. Now it’s time to get tweaking on CG and throws.

It for today I’ll enjoy the Direct Connection FA-18 Blue Angel converted to my friend’s F-15 in Langley tail flash and from glow to electric. It was a huge challenge, it worth the build.

53” WS, 59” long
.80 Rimfire motor
100 ESC

My Airfield Tempest 800mm (31”) Warbird would just never fly right. It only had one battery and a dedicated Tx that took 8 AA batteries. When it did a destructive nose dive it had enough cracks and bent motor shaft that I was done with it.

The electronics came out easily enough. It was like stripping out the nervous system of some kind of dead robot. The control rods were very long and thin. The ESC was more like a motherboard. However I was impressed with the multiple inputs on the receiver and the string servers.

Lost my Carl Goldberg Electra in a gust. Hit a tree which sheared off the firewall forward. Then it glided into a nearby tree where it jammed into place 45’ up for four days and through one thunderstorm. .

Footballs thrown at it broke the fin/rudder. 50’ of 1 1/4” PVC jabbing at it just made me tired. What worked to bring it down was a golf ball taped to mason string. An underhanded slingshot throw wrapped around the offending limb. A few minutes of yanking on the limb finally brought her down.

She should be good to go in an hour or two. It’s one of the advantages of being a model-maker!

Here’s how to put a watermark on your airplane wing.

1. Decide if your wing is gloss, satin, or matte finish. Choose the opposite clear spray. My wing was covered in dull gray Monokote, which is more satin. I chose a rattle can spray that had a chalk dry look. The best for this is Testors Dullcoat.

2. Develop a design on paper. Imagine that it’s a negative. Cut it out and size to fit on the wing. I really like the Jesus fish (Ichthus).

3. Tape down what you can. I intentionally cut 1/4” gaps and filled them using blue painters masking tape. This helped provide some adhesion for the paper over the Monokote.

4. Spray the design right on to the wing and let dry.

5. Carefully peel back the tape and paper mask. Voila!

Gave some attitude to the red rubber pilot that came with my PZ Extra 300. Reflective visor was from a Twix candy bar wrapper. Straps were silver duct tape. Photos were printed from the cockpit of a real Extra 300. Paint: Tamiya gray primer, Rustoleum gloss black, Testors purple and orange. Canopy glue.

Don’t miss the pattern call sheet on the instrument panel.

The Parkzone Extra 300 manual included settings for Exponential plus high and low rates. Given some reports about this plane being twitchy and quick, I thought addressing the settings would be wise. I also set the Throttle Cut on A. I plan to fly on low rates.

Buying planes is so much fun! My daughter's boyfriend sold me his Sig LT-40 and got me into RC planes. I have a friend who loves antiquing. He's found a prop jet for me for $200 that has been a learning experience, for sure. I found a Carl Goldberg Electra powered glider uncovered balsa frame in an antique mall for just $25. And I've seen a Jetco Navigator with fuel stains all the way back to the elevator for sale for $400 "firm." (I ran away from that one.) FB Marketplace had a Nitroplanes Long EZ near my parent's home that I quickly bought. And just last week I found a Parkzone Extra 300 in excellent shape from a guy living just 10 minutes away.

I've picked up some tips. Keep in mind even if you want to convert to electric like I do, there's money in the old glow engines (I sold a .91 Super Tigre and tuned pipe for 57% of what I paid for the whole plane. Hobby shops aren't the only place guys sell planes. Look on FB Marketplace, Craigslist, eBay, Amazon, etc. Buyer beware, but with some careful analysis, I think you'll have a good experience.

Here's my checklist that I've been cutting and pasting into for a couple of years. I appreciate all the wisdom passed along!

Throw the battery out and get a new one. Lipos, NiCad, watch battery, AA's, AAA's, etc.
Hand turn the prop to check for compression and other bad feelings.
Look for signs of pitting and rust in the piston/engine
Dirt in the carb
Replace the glow plug
Check for stripped servo gears

Today I purchased a very used Parkzone Extra 300. It was produced around 2010 as a BNF ($230) and PNP ($185). I got it for $60 through FB Marketplace from a guy that lived just 10 minutes from me.

Walt Extra, a German, developed the Full scale Aircraft. The RC version is 1/7.9 scale. Dimensions:
Length: 22 ft 8 in // 36.8”
Wingspan: 26 ft 3 in // 40.6”

The RC plane was reviewed and discussed many times. Some people got a version that flew better with the wings bolted on upside down. This plane has an AR600 receiver. The AR500 that originally came with it was discontinued because of multiple failures. The seller threw in an Orange receiver.


My $60 version of the plane had a new cowl. The replacement cowl did not have silver and purple trim, but I’m working on that. It had a bloated 3S 2200 Lipo that had to be coaxed out of its cramped cubby hole. Both orange wheel pants were long gone. The cigarette smell was knocked down by Windex.

After binding, all the Servos and control surfaces seem to be working great. The “15-size” motor and custom 10.5 x 5e prop seem very strong.

The seller was not the original owner. I applaud him for selling it when he realized that electrics were not for him. He was a balsa builder / glow engine flyer and was glad to get it into the hands of an electrics guy.

Update: Sanded and repainted the scuffed spinner. Found an orange Sharpie and touched up the scuffed places. Upgraded wheels from 1 3/4” to 2 1/4” foam. Painted orange sections black on the bottom side.

Five years is a long time to gawk at beautiful paint jobs on model planes. Over and over the modeler explained their airbrushing techniques. I finally bought a good enough model that I really wanted it done right. The Tamiya F-15C had a two-toned camo finish that was ideal for airbrushing.

If you've not tried it, let me encourage you to take a step of faith. One guy helped me buy an inexpensive generator. Another guy provided good counsel on the primer, paint, and lacquer thinner to buy. Hobby Town had the supplies I needed, including a book on beginning airbrushing. YouTube had instructional videos.

Perhaps it was good that the first airbrushes I purchased were dirty and clogged. I purchased six at an estate sale for $10.00. They bubbled up in the paint cup with air backing up. Little, if any, paint made it on to my test sheet. It was good because it taught me the importance of clean-up to keep the tips clean. A friend suggested buying the $20 airbrush kit at Harbor Freight. This airbrush changed everything. It ran very smoothly.

The technique was not hard to master. I learned to push down to get air flowing and then pull back to get the paint flowing. After testing on 3" pieces of discarded plastic model parts, I did find it difficult to paint a straight line on the 1/48 scale F-15C. The under-shading was a huge first step (see photo). That would never be possible without an airbrush. However, changing out to a different color was another skill to master....Continue Reading

Over the past five years, I have enjoyed developing build logs for my rc airplanes. This year I printed them out and put them in a 3-ring binder. Each sheet was put in its own protective sleeve. I also keep an electronic file. I think long after my planes are gone, this notebook will outlive them all.

Why? Each of my build logs has been on very different planes with different set ups. I suppose if all you build is variations on a J3 Cub, it would get boring. However, I write my own build log with detailed photos so that I have a reference.

I develop my build logs in PowerPoint. I use my smartphone to take photos and insert them. I often have to crop for space and sizing. If something is really cool, I might make an entire page of that stage of the build.

Who? Who do you develop a build log for? A build log on rcgroups.com is likely very different from one you are developing for your own records. I have read through at least 20 over the past five years. Some chase rabbits right in the middle of the build with five or six posts talking about some fly-in they attended. It becomes a pseudo reality show that encapsulates what was going on during the build. I also note with chagrin that many build logs just stop. Did the OP die? Did the OP finish his plane and it was a so bad that he couldn't return to what he did? While others do an incredible job of detailing certain aspects that become a reference quoted by others in other builds.

What? So, what should a build log for...Continue Reading

UpNup has several meanings to me.

1. A little electric Champ I started out with flew up and up and out of sight about the time that I discovered RCgroups.com. I needed a handle and chose this one.

2. A person who is on the up and up is someone I admire. It’s all about integrity. J R Ewing on Dallas was asked how he could be so terrible to others. He said, “It’s easy if you have no integrity.” I would like for others to see me as a follower of Jesus who walks the talk. A guy that can be trusted, valued, genuine, and honest.

My life verse from the Bible is Philippians 2:13: “For it is God who is at work in you to will and to act according to His good purpose.” That’s a pretty high calling.

Shakespeare wrote, "Now is the winter of our discontent." (Richard III) In the middle of slogging through a build, sometimes it seems to go on and on. I look at those sleek ARFs and wonder why I'm doing this. The past two weeks have been particularly difficult trying to get an .80 Rimfire motor to brace inside an incredibly narrow F-15 nose. After a week of exploring options, I sawed off the cowl. Any surgeon will try to avoid surgery. But it opened up a world of options toward a successful conclusion.

Not to be overly dramatic, but a couple of Bible verses came to mind from the Apostle Paul: "We also boast in our afflictions, because we know that affliction produces endurance, endurance produces proven character, and proven character produces hope" (Romans 5:3-4 CSB).

So, there is a bigger picture for balsa building: perseverance builds character and hope. And this world could use with a whole lot more hope.
