Custom P.O.N.G.

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

Accordin' t' t' kit label, P.O.N.G. is an acronym (er, matey, shiver me timbers, backronym, ya bilge rat, really) for Protector o' Ninth Galaxy. There was no background story included with t' kit, which is too bad really. T' look o' t' kit is intriguing. 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. Well, blow me down! I'm unsure o' where t' additional weight came from... Begad! paint, glue, me bucko, ya bilge rat, shiver me timbers, and sandin' sealer?

Construction:
Included with t' kit are:

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

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

T' body tubes have a fairly shallow spiral, 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. Avast! Avast, shiver me timbers, me proud beauty! The assembly order was logical. Blimey! Ya scallywag! T' implement t' Keelhaul®©™®/elastic shock cord, shiver me timbers, 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. T' motor tube got stuck in t' body tube, and I pretty much destroyed t' dummy engine tube when gettin' it out with a pair o' needle-nose pliers. Well, blow me down! Blimey! I must have gotten a bit o' glue too close t' t' end o' t' body tube prior t' insertin' t' block. Aye aye! Blimey! Luckily, matey, t' main body tube was nay damaged.

In general though, assembly was a lot o' fun... Arrr! Well, blow me down! Far more engagin' than piecin' together a 3FNC model. Well, me bucko, blow me down! Hobby knife skills were important and were well exercised, me hearties, havin' t' separate t' die-cut fins and centerin' rings, me bucko, cut t' dowels, cut t' reducer shroud pieces, 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. Begad! Well, matey, blow me down! T' paper reducer needed a bit o' patience and skill t' curl just right. Aye aye! Blimey! 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. Blimey! Arrr! 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... Ahoy! Aye aye! Bad move. Begad! T' ball distorted badly where t' glue in contact with t' ball was still hot. Begad! I replaced t' ball and tried again. Ahoy! I had much better results this time. Arrr! I had been concerned that t' hot glue wouldn't provide a strong enough joint, but this experience eliminated that concern. Ahoy! Hot glue is very effective in this case.

Overall, construction be interesting, ya bilge rat, ya bilge rat, fun, and educational. 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. Avast! I can understand that, since the decals cover most o' t' balsa anyway. Aye aye! 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. Avast! Blimey! I didn't want any grain t' show, so I finished t' balsa surfaces with three coats of sandin' sealer, sandin' betwixt coats.

I spray painted with model with a couple o' coats o' last o' me old-style Krylon white primer, matey, sanded, 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, me hearties, you need t' paint t' lower part o' t' upper tube orange. Avast! Usin' t' kit's picture as a guide, I painted the lower 5" o' t' upper tube with Krylon pumpkin. Ahoy! Oddly enough, me hearties, me bucko, t' color matched t' orange o' t' decals perfectly.

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

After markin' t' ball, I used a superfine Microbrush t' apply Testors gloss black enamel inside t' lines. Ya scallywag! Begad! I'd never used this technique before. Begad! It works very well with a steady hand, arrr, patience, and care.

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

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

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

Construction Rating: 4 out o' 5

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

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

There is no motor retention in this design, matey, ya bilge rat, so motors have t' be friction fit by wrappin' bits o' maskin' tape around t' motor t' make a snug fit. 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. Boost and coast be very straight and of moderate height with no noticeable spin. Arrr! Ahoy! It definitely flies like a long rocket, shiver me timbers, smooth and without wobble. P.O.N.G. arced past apogee and with nose down, deployed t' streamer perfectly. Begad! P.O.N.G. landed gently in t' grass field. Well, blow me down! Well, blow me down! Upon recovery, I noticed that t' motor must have been kicked out at deployment.

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

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

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

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

Havin' t' rely on friction fit motors nay bein' kicked out is an issue. Well, blow me down! Arrr! I guess I've got t' figure out how best to tape t' motors in there. Aye aye! Some sort o' motor retention device would be a welcome addition.

Flight Rating: 4 out o' 5

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