Odd'l Rockets Goony G-16 Build, Part 10, Nose Cone Divot Touchup - TIP


The canopy is glued in place  using CA glue.
CA glue can get brittle over time. I'd recommend adding a bit around the edges every once in a while to keep it secured.

The canopy decal strips were overhanging the sides after the decals dried. these are trimmed off using a razor blade.
Look at the upper right along the canopy edge. The razor blade cut chipped some white paint showing the black nose cone plastic underneath - ARGHHHH!



For touch-ups I use the same paint I used on the body. Rusto 2X paints can be temperamental but they do blend very well on touch-ups.

A small snack bag is pressed into a mixing cup.
Paint is sprayed into the cup making a small pool in the bag.
NOTE: Metalhead1986 commented that Krylon spray paint will eat right through the plastic mixing cup!



Dip a toothpick into the paint retaining a small drop on the tip.

Set the tip into the chip recess letting the paint fill the divot. Don't use the toothpick as a brush, just place the tip and let the paint run into the chipped area. It might take two tries to fill the hole.







Pick up any excess paint outside the divot with a Q-tip.

It's not perfect but a whole lot easier than masking and spraying again.

Odd'l Rockets Goony G-16 Build, Part 9, Decals TIP

I always read of water slide decals  problems. Some builders dread them and won't even try to apply a decal.
In my Odd'l Rockets kits I include "Extras" or practice decals. Start with those smaller extras first! It's tempting to apply the largest, most colorful decals but save them for last after you get a feel for the decal soak times and how they transfer.

TIP: Always wet the surface of the model with a wet finger. Rub the water back and forth and leave on the surface.
This gives the decal some surface lubrication and lets you position and re-position the decal until it is where you want it.

When re-drawing decals for a Goony you should poke fun at the original design.
Obviously you include the word Goony on the decals. I replaced the stylized eagle with a duck. The duck wasn't part of the first Goony F-16 build, the decal was changed after the model was finished. The center star was changed to a target with cross hairs.
The CAUTION decals made me think of things my Mother would warn me about.



Some of the references are a little inside like the number on the rear of the rudder decal.
The DANGER decals near the canopy were changed to DANGME.

Odd'l Rockets Goony G-16 Build, Part 8, White Paint and a Fix TIP



This is an easy one to paint, it's all gloss white.

After one coat I sanded down any rough fillets and glue blobs.


To keep paint out of the front end of the tube a wrap of masking tape went on the inside end.

The nose cone was painted separately because the Rusto 2X seems to take much longer to dry on plastic.
To hold the nose cone, masking tape was set down on one edge of some copy paper. This was wrapped around the nose cone shoulder.




I couldn't get a smooth surface on the bomb support sides, they are hard to reach with sandpaper.

So I cheated!
TIP: A piece of white decal paper was cut to size and set over the rough support surface.
This isn't something that works all the time, this is in an area nobody would probably notice. But it did cover and smooth out the rough side some.






Here's how it came out. Much better, not perfect but better.
I followed up with some Future clear acrylic applied with a Q-tip.

Odd'l Rockets Goony G-16 Build, Part 7, Canopy Continued



After flexing the scored line back and forth it should crack on the cut. If it doesn't easily crack, go back and lightly score the line again. Don't pull or tear the sides off, score and crack!



The edges could be a bit rough, especially around the front and rear.
Notice the pen lines are still there, they will be removed in the next step.
Wrap some 220 grit around the BT-60 tube.
Sand the bottom of the canopy back and forth over the sandpaper.

Keep sanding until the pen lines are gone, it should take about 10 minutes.
The problem for many builders is they don't work vacuform parts long enough. The Estes Saturn V fairings won't fit unless you sand them down a while. I've seen some Saturn V builds where the fairings weren't fully trimmed and didn't seat well.

You are getting close when small plastic "strings" hang off the sides. Look close at the lower right side. The sanded edge is barely hanging off the edge recess line.



This is the finished canopy from the underside. Note how clean the edges are.

Odd'l Rockets Goony G-16 Build, Part 6, Canopy


Here's how the canopy looks from the Odd'l F-16 kit.
You have to trim and sand the bottom to best fit the curvature of the nose cone. It's not as hard as it sounds.


Along the bottom of the canopy is a edge recess.
To see the line you will cut, a ballpoint pen line is drawn down the recess.
Right above the pen is a squiggly line on the cardboard. The plastic is slippery and you may have to "start" the ink a few times while tracing around the clear plastic.



Don't cut all the way through the plastic. SCORE the plastic with a sharp knife. The plastic will crack down the scored line by flexing on either side of the cut line. Don't flex the scored line yet.
Score a line all the way around the canopy. Relax and TAKE YOUR TIME!


On the corners cut a line from the scored edge to the outside of the clear piece. Here you do cut all the way through the plastic.
This makes it easier to flex and crack the scored lines in four segments all the way around the four sides.

Two New Saturn V Kits - Achhhh!




Why two kits?
I wanted to have them on hand just in case somebody wants one built. I have built a few for customers in the past.

The package lists the kit as a Skill Level 4. This should be a Skill Level 5 kit. Getting the vacuform wraps and fin fairings right should qualify it for a 5. The painting masks are very time consuming.







The last Saturn V kit I built had an additional small white background decal sheet. This sheet has the fin markings with the white ink.
The small UNITED STATES and flag decals still aren't curved to fit the conical command module.

I don't know why the yellow backing sheet is in the box. Everything was loose and the backing sheet was nowhere near the decals.
These decals say they were printed in China but there is no Chinese print on the yellow backing paper.

Here's the newer molded fins - no more vacuform fins in this kit!
I've read where some kits included both the older vacuform and molded fins. My kits had just the new molded versions.

A D engine yellow spacer tube is included at 2 3/4" long. The instructions show the longer 3 3/4" long E engine spacer.

I won't be building these any time soon, unless someone wants to buy a finished model. My previous blog build still applies to 90% of the latest kit version.

NEFAR Launch Bunnell, FL, April 22, 2017

I arrived around 11:00 a.m. counting 75 cars already there, more were arriving.
The two-day Bunnell Half Blast is turning into a big event.
On these two day launches the LPR and MPR launches are independent of each other. You can load and launch LPR without waiting for the larger rockets to fly.
Surprisingly the LPR launchers weren't busy until later in the afternoon. This was the first hot day of the Summer launch season.



Take a look at the new LPR launch controller designed by Steve Ghoto.
It is smaller than the picture lets on, the footprint is about 8" X 8". A very clean layout, the labeling is to be added soon.
Its wireless and transmits a launch signal to the relay switch near the rack.



Even thought the Goony G-16 is still being built on this blog, I flew it twice and was very stable.
First up with a Estes B6-4 it got to an estimated 300'. It touched down on hard dirt and cracked a fin. Gary had some white glue for a quick repair.
The second launch was with a Estes C6-5. Same straight flight boost but to approx. 500 feet. This time it landed softer with no damage.
A good start for an Odd'l prototype.



Boost gliders have never been my strong suit. I've had them shred on boost or glide away. The only B/G success I ever had was with the original Citation Bomarc, a pop-pod boost glider.
The Estes SKYDART is a classic, I've never flown one until now.
I did a dozen test tosses making slight adjustments on the elevon set screw.
Loaded with an Estes C6-3 it arced to the East to 300' and ejected the pod. It settled into a fast circular glide pattern. The glide was flat and I was counting. After ejection it did glide for 25 seconds!



My older Estes MINI SHUTTLE was flown with a German Quest B6-4.

There's not much room for the 12" parachute. The shock cord is pushed into the hollow nose cone first. The folded chute follows, half in - half out.
At ejection the shock cord (usually) pulls out the chute.
Altitude was an estimated 300' with no damage on recovery.



I delivered 10 of the new Odd'l Rockets F-16 kits on site to Roger and Bracha of JonRocket.com. Roger listed them right away, via his cell phone.

Here's Jim Lytle with his F-16 kit, he was the first to buy one!
As I was driving out Bracha stopped me to say through website sales the F-16 were already sold out! Thanks everybody - they'll be mailed out on Monday.
Apogee will have an allotment in a few days - I've got to make more kits!

The NEFAR field is large and my chance to fly larger engines. (Well, large for me anyway.)
The New Way N-20 DEMON was launched with a D12-5 engine to an estimated 700'.
There was no parachute at ejection! It fell slowly enough and landed with one shroud line draped over the corner of a range tent. Damage was minimal, a slight crease in the body tube.

This was one of the better launch days. A new Odd'l kit, two good prototype flights and a decent glide time with a filled and painted Skydart!
