Semroc Mini Optima Build Background

The Optima was a BIG model for Estes, available from 1990 - 1994.
2.6" diameter and almost four feet tall. D engine powered, it could reach 390 feet! 
A good demonstration model it featured chrome and metallic orange trim.

The same design was re-released as The Shadow in 1994 - 1996. The paint decor and decals were different.
The engine mount was adapted to fit the new (and short lived) E15 engines. E engine altitude was advertised at 550 feet.
This newer black and silver model was trimmed with a goofy blue name decal. For me it didn't have the appeal of the earlier Optima paint and trim.

The Semroc Mini Optima kit reflects the first paint scheme.

Old Enerjet Engine

I only have two original Enerjet engines, both are E24-7s meant for my Enerjet Nike Smoke.
This one has a hand written number on it, "477". You'd think that might mean April of 1977, but the Enerjet product line only lasted a few years. 
To see the 1972 Enerjet catalog: CLICK HERE

The casing looks to be fiberglass, the nozzle is graphite.
There is a bead of epoxy around the nozzle.

The upper end has an old style paper cap over the ejection charge.

Is it a coincidence that the new Quest Q-Jet labels are orange, black and white? 

One thing that hurt Enerjet sales was the price. Each E24 engine was $4.00 in 1972. That was way out of line for most hobbyists.
Let's hope that isn't a factor for the new Quest 18mm composite engines.

ASP D Region Tomahawk Build,Finished

All my experiences building and launching ASP kits has been very positive.
The D Region Tomahawk has always been a favorite, very clean lines.
This BT-5 based model should perform well even with a 1/2A3-4t engine. Sure, it would look best with a flat finish but I want to keep the model clean.

Quest Q-Jet Composite Engines (Almost) Available!

On the NAR Facebook page Roy Green posted:
"Quest Q-Jets (Composite A and B) are now up on their website. Certified by TRA. Priced about 20% more than comparable Estes motor . . ." 

For now - If you try to add the new engines to your shopping cart you get a "Product Unavailable" message. To go to the Quest Aerospace website: CLICK HERE
A3-4, A3-6, B4-4 and B4-6 engines are sold in two-packs. A engines are $7.99, B engines are $8.99.

Looks like C8 and D12 engines are also on the way . . . 
That 18mm D12-3 engine might be perfect for models like the Mars Lander.

ASP D Region Tomahawk Build, Part 17, Nose Cone Tip Paint

Just the very tip of the nose cone is brown.
The instructions say you could dip the nose cone tip in paint, it's worth a try.

The same brown from the nose cone base was sprayed into a baggie set in a mixing cup.

The nose tip was dipped in the paint but I couldn't get an even line.

I came back with a paint brush trying to straighten out the edge. That only made the paint surface uneven.

After the brown completely dried the high spots were lightly sanded with 400 grit.
I sprayed more paint in a cup and brushed again. This time it came out better.

ASP D Region Tomahawk Build, Part 16, Fin Plate Setting and Streamer

The backs of the card stock fin plates were sprayed with 3M 77 adhesive spray.
Here's how the plates fit around the curve of the tube and with the folds tucked into the fin root edges.

The great thing - the fin plates covered the bad and touched up mask lines.

A Q-tip was used to gently press the fold into the root edge. You won't scratch the print using a soft burnisher.
There is a 1/8" wide aluminum band at the rear edge of the body tube. Instead of masking and painting, a strip of Trim Monokote was cut and applied. It took a few tries to tuck it into the fin base but it was easier than masking.

The streamer is thick yellow plastic, 3" wide X 24" long.
The streamer is taped to the shock cord, 1" from the end of the streamer. Fold the end over the shock cord and tape it again.
