Default ..look above-Ranger update

Gh,

IIRC, Vern built the Big Bertha as a demo model to fly at "Cape Estes", the company flying-demo field.

Semroc's Brighton, a scaled up Ranger, is my favorite kit that Carl manufactured.
With the interchangeable engine mounts (4 18mm, 3 24mm, single 24mm and 29mm)
what's not to like?

Have built 2, one more to go when I find a good color scheme.

p.s. Brighton on a CTI H-54; fire and brimstone! NARAM 54 2012 Muskegon Mi.

...and yet the Big Bertha, which started life as a single-engine Ranger as Bob mentions just above, has been in longer continuous production than any other model rocket kit. It first appeared as a plan in MRN in the middle of 1963 and being released as a kit some time in 1965 (I didn't find it as a new product announcement in the MRNs on JimZ's site, but since the Alpha, at K-25, was listed in the December 1965 MRN, the K-23 Big Bertha kit likely was "on the street" by then).

I need to dig out my Ranger clone and give it a flight or three.

....and I've never tried the filler primer that's the real subject of this thread, but it sounds like I won't be able to, now.

Thanks Scigs, I'll have to give it a try. I did try Seymour PBE Filler Primer. It's good, made in the US, and reasonably priced (15 oz / $12), but still not as sandable as the 3M Bondo primer. The UPOL stuff looks pricey, at least on Amazon - where did you obtain it?

UPOL appears to have several different gray sandable primer formulas.

AutoZone stocks a 10 oz. spray can of the U-POL Gray Expert Sandable Primer Professional Grade UP2722 for $9.99 a can: https://www.autozone.com/paint-and-...er/1244310_0_0?

AutoZone also stocks a 10 oz. spray can of the U-POL Gray Anti-Rust Sandable Primer UP2088 for $9.99 a can: https://www.autozone.com/paint-and-...7LHkb-au4Vc2eOs

UPOL also sells a U-Pol Products 0791V Grey HIGH#5 Primer -12 oz spray can, and a U-POL Products 0791-A Grey HIGH#5 Primer - 15.2 oz. spray can, but not sure how any of these U-POL products compare.

Kind regards,

Love that paint scheme on the Ranger. May have to do one up that way. Very nice.

Hi RZ,

Which Ranger; Stine's florescent orange, b, w, silver or the orange and white?

Can't wait for the aforementioned vinyl in order to make 'em better.

Bob
p.s. pretty sure I've figured Stine's "invisible" fin/fin side colors. If not, it'll
be close enough; as in it's not even ready to paint yet.
