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 its time to get tweaking on CG and throws.

It for today Ill enjoy the Direct Connection FA-18 Blue Angel converted to my friends 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!

Heres 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 its 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.

Dont 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.

https://www.modelairplanenews.com/pa...extra-300-bnf/

My $60 version of the plane had a new cowl. The replacement cowl did not have silver and purple trim, but Im 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.

If you read my blogs, youll learn that I typically make a plastic 1:48 scale model of the RC plane that Im building.

I finally found a 1/48 scale Tamiya F-15 C that has the right tail flash FF from Langley/Elgin AF base. If youre not familiar with the plastic modeling world, Tamiya is known for excellent scale authenticity, exacting fit, and finish quality. And to seal the deal, I saved $10 by purchasing thru eBays app. The only catch is its coming from Hong Kong in about a month. However, I found the Tamiya manual and painting guide online. The plastic kit was made in 1991, but it is pretty close to the 1986 version Im modeling.

Had to get together a number of graphics for the F-15 Eagle and its pilot. Some, like the afterburners were made with PowerPoint. Theyre in 1/11 scale.

UPDATE: Sent my artwork to Callie Graphics and Callie turned original artwork around in five weeks.

No manual exists. I saw an ancient blurry photo online that held the key.

1. Epoxy ply rails in place, buttress them, and drill holes. It is easy to do this if the fuselage is not fully in place. Otherwise youll have to cut. Use a micro-saw against the grain of balsa and a hobby knife with the grain.

2. Connect the steering mechanism first. Run a stiff line from rudder servo to the clevis at the swivel point. Id recommend a braided cable if a wire rod isnt available. I ran mine inside a flex tube that was epoxied to the fuse every two inches. The steering mechanism must swing parallel to the motion of the retract. The nose wheel strut must be firmly held into place by an Allen screw.

3. Open the control rod metal clevis and put the outermost swing arm inside the clevis pin. Make sure the clevis pin goes to the outside away from the strut. Put a metal clip in the brass pin of the clevis. Do not use any other method to secure the clevis such as a 1/16 portion of fuel line.

4. Make sure the nose retract locks both down and up. The control rod clevis for the retract must match the distance. I recommend doing this in the down position.

5. Screw the retract in place making sure the blind nuts seat or bite firmly into the ply rail.

6. A mechanical retract typically uses one strong servo and bends wires into a round servo control piece. Make sure the servo is the the down position when hooking up the clevis arms on the retracts.

Note. The photos were taken when replacing broken retracts that had been epoxied into place. The Hobbico mechanical retracts from 1995 did not match the holes of their 1999 version. All the innards did match, so I swapped out the sides. For whatever reason both old and new nose wheel retracts had rail screws glued into place. Two of the four screws in EACH retract had to be sawed off.

An RC Pilot Goes to Heaven

One day when life is over
And before my Lord I stand,
Hell look at me with eternal love
And a model in His hand.

Itll look just like the one I flew
Upon the wind so free.
Id built it in my shop to fly
And from the world set free.

Jesus held it out for me
And asked me how it flew.
Memories came flooding in right then
It was my life reviewed.

He asked me if Id really felt
The Creators hand in mine?
To plan, to cut, to sand, and coat,
Until the plane was fine.

He opened my mind to see the save
When that earthward plunge pulled up
I saw His hand beneath the wings
And yet I counted it luck.

I heard my heart then heave a sigh
When flying out of sight
Up and up, it went so high,
No longer in the sky.

A little prayer Id prayed that day
Hed heard it bye and bye.
But I missed how He comforted me
Flying buddies by my side.

I remembered all with clarity
No longer with remorse.
The Lord had been there all along,
A Friend to me, of course.

I took the plane from the Masters Hands
And looked at it anew.
Jesus had kept it safely here
A joy for me He knew.

I launched the plane, it flew away.
Twas perfect now like me.
I saw the twinkle in His eye,
A friend to modelers He.

Today I submitted Harley Michaelis’ name to the AMA’s Hall of Fame review group. My nomination gave them seven pages including a cover page, their nomination form, biography, achievements, testimonials, links to articles and videos, and a page of photos.

It was good to review my past year interacting with Harley. He died October 12, 2020 and his ashes were buried next to Patricia in Walla Walla, Wash.

Harley was 99 years old and had outlived so many that he had trained, competed against, and inspired. He had become a Christian two years after marrying Patricia and lived out his faith.

He deserved this nomination. I’m glad to have made a long overdue nomination.
