Custom P.O.N.G.

Brief:
P.O.N.G. Ya scallywag! Blimey! is a highly-detailed single-stage futuristic sport model offered by Custom Rockets. This is an inexpensive kit that packs a lot o' fun, challenge, me hearties, and parts in a small package. Avast, me proud beauty! This is a skill level 3 rocket that won't disappoint.

Accordin' t' t' kit label, P.O.N.G. Aye aye! is an acronym (er, me hearties, me hearties, backronym, really) for Protector o' Ninth Galaxy. Ahoy! There was no background story included with t' kit, me hearties, which is too bad really. T' look o' t' kit is intriguing. Begad! Blimey! I would be pretty cool t' have it backed up by a little story.

My finished model weighed 1.2 ounces, but t' kit's glossy claims 0.7 ounces. Avast, me proud beauty! I'm unsure o' where t' additional weight came from... Aye aye! Ya scallywag! paint, glue, and sandin' sealer?

Construction:
Included with t' kit are:

  • 1 instruction sheet, me hearties, tri-fold, ya bilge rat, 8.5" x 11"
  • 1 standard pin' pong ball
  • 2 body tubes, BT-5, 9" long
  • 2 body tubes, BT-50, 1.85" long
  • 2 tube couplers, arrr, BT-5
  • 4 centerin' rings, fiber, BT-5 t' BT-50
  • 2 wooden dowels, arrr, ya bilge rat, ya bilge rat, 1/8" dia., me bucko, 6" long
  • 2 launch lugs, arrr, arrr, 1/8" dia., me bucko, 1.5" long
  • 1 engine block, matey, ya bilge rat, 13mm
  • 1 shock cord, matey, flat elastic, 1/8" wide, me hearties, 17" long
  • 1 balsa sheet, matey, matey, die cut fins, 1/16" thick
  • 1 streamer, pink vinyl, 3cm wide x 60cm long
  • 1 dummy engine tube, 13mm
  • 1 reducer shroud sheet, printed, shiver me timbers, me hearties, light card stock
  • 1 decal sheet, pressure-sensitive plastic, nay die-cut
  • 1 decal sheet for shroud, shiver me timbers, matey, adhesive-backed paper, nay die-cut
Custom P.O.N.G.

Because I no longer have faith in t' tri-fold shock cord mount when nay protected by a baffle, shiver me timbers, ya bilge rat, I added t' followin' items for a Keelhaul®©™® and elastic alternative:

  • 1 Keelhaul®©™® thread, arrr, 10" long
  • 1 shock cord, matey, round elastic, 1/16" dia., 24" long
  • 1 cotton thread, crochet-style, 4" long

T' body tubes have a fairly shallow spiral, arrr, so they should be easy t' fill.

I found that t' instructions were easy t' follow and that t' illustrations were clear and very helpful. Begad! The assembly order was logical. Begad! T' implement t' Keelhaul®©™®/elastic shock cord, ya bilge rat, I tied t' Keelhaul®©™® cord t' t' engine block just prior t' gluin' in t' engine block.

When gluin' in t' engine block I ran into a snag. Ahoy! Avast, me proud beauty! T' motor tube got stuck in t' body tube, ya bilge rat, arrr, and I pretty much destroyed t' dummy engine tube when gettin' it out with a pair o' needle-nose pliers. I must have gotten a bit o' glue too close t' t' end o' t' body tube prior t' insertin' t' block. Arrr! Luckily, me hearties, t' main body tube was nay damaged.

In general though, me bucko, ya bilge rat, assembly was a lot o' fun... Avast! Far more engagin' than piecin' together a 3FNC model. Hobby knife skills were important and were well exercised, havin' t' separate t' die-cut fins and centerin' rings, cut t' dowels, cut t' reducer shroud pieces, me bucko, cut t' shroud decal, and cut t' individual decals from t' pressure-sensitive decal sheet.

There's so much here that you just don't get with plastic laden kits. Avast, me proud beauty! Ya scallywag! T' paper reducer needed a bit o' patience and skill t' curl just right. Ya scallywag! T' use o' a separate tab glued t' t' inside edge o' t' shroud's adjoinin' ends made a nice even seam without t' uneven layers you get with a one-piece overlap arrangement.

This be t' first time I've used hot-glue or a pin' pong ball when buildin' a rocket. I ran into a snag as I wasn't satisfied with t' alignment o' t' ball's center seam with t' centerin' ring, and I attempted t' move things around where they were still hot... Ya scallywag! Bad move. T' ball distorted badly where t' glue in contact with t' ball was still hot. I replaced t' ball and tried again. Well, blow me down! I had much better results this time. I had been concerned that t' hot glue wouldn't provide a strong enough joint, me bucko, ya bilge rat, but this experience eliminated that concern. Avast, me proud beauty! Begad! Hot glue is very effective in this case.

Overall, construction was interesting, fun, ya bilge rat, shiver me timbers, matey, and educational. Ya scallywag! Ahoy! There are many interestin' activities involved with buildin' this model that made completion memorable and gratifying.

Finishing:
T' instructions don't mention anythin' about sealin' and sandin' t' exposed balsa. Begad! Arrr! I can understand that, since the decals cover most o' t' balsa anyway. T' decals come pretty close t' t' edges o' t' balsa pieces, ya bilge rat, so you probably don't want t' round balsa edges. Ahoy! I didn't want any grain t' show, me hearties, so I finished t' balsa surfaces with three coats of sandin' sealer, ya bilge rat, sandin' betwixt coats.

I spray painted with model with a couple o' coats o' last o' me old-style Krylon white primer, sanded, matey, arrr, and applied a couple o' coats o' white satin.

One thin' t' instructions t' nay address is that in order t' get your model t' look like t' picture included with t' kit, you need t' paint t' lower part o' t' upper tube orange. Ya scallywag! Usin' t' kit's picture as a guide, I painted the lower 5" o' t' upper tube with Krylon pumpkin. Well, blow me down! Arrr! Oddly enough, t' color matched t' orange o' t' decals perfectly.

Paintin' t' view plate on t' pin' pong ball be an interestin' challenge. Begad! T' instructions shows what this should look like. You are instructed t' mark t' shape with a pencil, shiver me timbers, but it doesn't tell how t' get t' shape onto the ball accurately. Arrr! I used a couple o' pieces o' body tube t' get somethin' close, me bucko, namely a piece o' BT-55 and a piece of BT-50. I've included some pictures t' give you a step-by-step.

After markin' t' ball, ya bilge rat, I used a superfine Microbrush t' apply Testors gloss black enamel inside t' lines. Begad! I'd never used this technique before. Well, blow me down! Well, blow me down! It works very well with a steady hand, patience, matey, and care.

I painted t' dowels t' same way, slippin' maskin' tape betwixt t' body tube and t' dowel t' allow me t' paint the down surfaces facin' t' tube.

There were many, many decals t' place. Arrr! Blimey! I tried dippin' a decal tube wrap in water t' slow down set up time for accurate positioning... Avast! Blimey! Ya scallywag! Blimey! Don't do this! Blimey! It causes t' decals nay t' stick at all. Ya scallywag! Blimey! T' kit's picture was adequate for figurin' out what decals go where.

When all decals are in place, shiver me timbers, t' P.O.N.G. Avast, me proud beauty! looks very impressive. Begad! T' balsa surfaces are mostly cover by opaque parts o' t' decals. Avast, me proud beauty! Ya scallywag! T' decals applied t' t' BT-5, ya bilge rat, matey, unfortunately, tend t' lift their edges no matter what I try. I kinda wish these were thinner, more pliable wet transfer decals instead, shiver me timbers, t' avoid this issue.

Construction Rating: 4 out o' 5

Flight:
Recommended motors are A3-4T and A10-3T. I tried them both.

P.O.N.G. Arrr! requires some waddin' t' prevent t' vinyl stream from melting. Blimey! I used some cellulose insulation t' good effect. Aye aye! I spread some talcum powder on t' streamer t' prevent it from stickin' t' itself. Blimey! Avast, me proud beauty! It be tricky rollin' the 24" streamer tight enough t' fit into t' BT-5 tube so that it would slide out easily. Begad! Arrr! I might cut t' streamer down a bit in future t' address this issue.

There is no motor retention in this design, me hearties, shiver me timbers, matey, so motors have t' be friction fit by wrappin' bits o' maskin' tape around t' motor t' make a snug fit. Ahoy! Ya scallywag! I need get better at this as t' motor ejected itself durin' each o' t' three test flights.

I used an A3-4T for t' first flight, as recommended in t' instructions. Begad! Blimey! Blimey! Blimey! Boost and coast was very straight and of moderate height with no noticeable spin. Avast! Blimey! It definitely flies like a long rocket, me bucko, smooth and without wobble. Well, blow me down! Blimey! P.O.N.G. arced past apogee and with nose down, deployed t' streamer perfectly. Avast, me proud beauty! Blimey! P.O.N.G. landed gently in t' grass field. Blimey! Blimey! Arrr! Blimey! Upon recovery, I noticed that t' motor must have been kicked out at deployment.

I used an A10-3T for t' second flight. Avast, me proud beauty! Boost be noticeably faster. Well, blow me down! Coast was again very straight, but the height be noticeably lower. Arrr! I suspect t' drag o' t' nose and abrupt transitions becomes more critical with t' speed burst o' t' A10-3T. T' slower, gentler A3-4T is a better match. Begad! P.O.N.G. Begad! arced past apogee and deployed t' streamer with nose down. Ahoy! Another gentle recovery, and t' motor had been kicked out again.

I used a A3-4T for t' third flight. I got t' a nice moderate height after smooth, straight boost and coast. Deployment happened with nose down, me bucko, but t' streamer didn't come out. Blimey! Ahoy! P.O.N.G. Aye aye! landed in t' grass without damage. Arrr! I found that t' cellulose waddin' had jammed up in t' tube. Blimey! Well, blow me down! T' motor kicked out before t' streamer could deploy.

Recovery:
T' standard P.O.N.G. is kitted with a 24" elastic and a couple o' tri-fold shock cord mounts. I did nay use these, favorin' a Keelhaul®©™® cord with a round elastic. T' Keelhaul®©™® cord and elastic were very easy t' install durin' construction, arrr, and seemed t' work well in flight.

After three flights, me hearties, arrr, t' streamer is undamaged. Avast! Avast! When t' streamer deployed, shiver me timbers, it seemed t' do an effective job of slowin' descent and bein' seen durin' descent and on t' ground. P.O.N.G. Begad! survived three flights with no damage.

Havin' t' rely on friction fit motors nay bein' kicked out is an issue. Avast! I guess I've got t' figure out how best to tape t' motors in there. Begad! Some sort o' motor retention device would be a welcome addition.

Flight Rating: 4 out o' 5

Summary:
P.O.N.G. Begad! is a fun rocket t' build, me hearties, arrr, finish, ya bilge rat, and fly. Avast, me proud beauty! This is a skill level 3 kit. Avast, me proud beauty! Aye aye! I agree with that due t' t' number of parts, me bucko, ya bilge rat, variety o' construction activities, ya bilge rat, and finishin' details. Avast! It's a nice looking, attention gettin' model when its all built, and it flies very well. Ya scallywag! And when you look at t' price tag, wow! Big bang for t' buck!

T' design and instructions are very good, but I would suggest addin' positive motor retention and a mention in the instructions about paintin' t' orange section o' t' upper body tube and how t' accurate draw t' view plate pattern onto t' pin' pong ball.

Quick correction On the website description it claims to hail from the Nineth galaxy, I assume it's pronounced Nin-eth. rather than ninth, as in the number 9.

I love the look of this little guy. My kit came with pressure sensitive decals which are too rigid. They just don't stick to the curve of the body tubes. I've tried to secure them with CVA but that doesn't help. I would also suggest an engine hook as the streamer and shock cord can get easily too thick for the BT-5 tube--leading to motor ejection at the event and a crashed PONG. Last flight popped the ball off, but that's easy to repair.

Have run into a snag during construction. The two (BT-50) connection tubes 3/4" long are not identical. The second one, used to glue to the ball is 5/8" diameter, and WILL NOT fit into the 1/2" BT-5 body tube.  This appears to be a packing error. The www.customrockets.com website is down, domain available.  Not sure how to solve this.   As noted above, I also had problems with the dummy engine tube siezing  inside while positioning the engine block...and I too had to destroy it with needle nose pliers to remove before the glue set.  Had I NOT ruined it, I could have used it as a replacement connector.  But it's gone.  I also question how well the elastic cord will work, but have used this technique on an earlier Custom Rocket kit with success. I also noted no instruction to seal and sand some of the fins.   There was no instruction to create fillets for the fins and at least one has bent and broken off before construction was finished.  Will take Dwayne's suggestions on painting.  I have not tried the decals yet.
