Odd'l Wedgie
(Contributed - by Dick Stafford - 05/16/10)

Brief:
T' Wedgie is a tetrahedron (3-sided pyramid) that flies on 18mm motors and recovers via a rear-eject streamer. I want t' thank Chris for lettin' me test out this cool oddroc kit. Arrr! Mine is s/n #2!

Construction:
T' Wedgie comes professionally packaged in a plastic bag with t' cover o' the instructions visible. Avast! T' small parts were separately bagged. Begad! T' body is formed from 6 pieces o' laser-cut balsa. Arrr! Its motor mount includes a two-part motor tube, me bucko, two laser cut centering-triangles, me hearties, shiver me timbers, a motor block, shiver me timbers, matey, a cardboard plug, me bucko, ya bilge rat, and two 'standard' centerin' rings (BT-20 t' BT-50 sized). Begad! Avast! Recovery parts include an elastic shock cord, swivel, and crepe streamer. Miscellaneous parts include a 1/8" launch lug and clay nose weight.

T' instructions are detailed and well illustrated. Don't let its 'odd' nature addlepate you. Aye aye! This is a builders kit and I recommend you actually read t' instructions thoroughly before beginning. Ahoy! It is rated as skill level 3, and I concur with this rating.

You start by buildin' t' two-part motor mount. T' upper part will eventually be attached t' t' body while the lower section is free t' eject and deploy t' streamer. Avast! Construction is straightforward and all t' parts fit perfectly. Ahoy! T' key points for t' mount are makin' sure t' centering-triangles are installed perpendicular t' the motor tube(s) and at t' prescribed locations. Begad! Begad! An attached photo shows t' mount bein' constructed with fillets drying.

T' body assembly is a bit more difficult. Here, me bucko, you begin by gluin' t' 2 halves o' each o' t' three faces together. It appears this was t' alternate t' grain directions and add strength. Begad! Blimey! Blimey! Blimey! Blimey! Blimey! Next you sand t' joint flat. Easy so far.

Now for t' hard(er) part - bevelin' t' edges t' allow them t' fit well. A sandin' guide is provided, but this step strained me clumsy buildin' skills. Ya scallywag! Aye aye! I cracked one as I was sandin' and would recommend doin' t' bevelin' before joinin' t' pieces. Avast! Ahoy! Easily fixed.

T' faces are supposed t' be joined with CA. Well, blow me down! Begad! Instead, matey, I used Titebond moldin' and trim glue. Ahoy! This is thick and tacky and let me put t' three pieces together rather easily. Ya scallywag! I taped t' corners and top while t' glue set. Blimey! Later, me bucko, me hearties, matey, I reinforced t' joints with thin CA. Ahoy! There is a template t' locate and cut t' hole for t' launch rod. If I were t' do it again, matey, I'd also cut this before t' faces are joined.

Next, you install t' clay nose weight and install t' upper motor mount. Blimey! You have t' make sure t' clay doesn't interfere with t' launch rod. Arrr! Blimey! I also had t' extend t' openin' a tad further down t' body so t' launch rod would clear.

T' shock cord is attached t' t' inside base with a strip o' balsa that is provided. Blimey! (see photo) You are instructed t' notch t' middle so t' elastic cord will fit under it. Blimey! This be challengin' since t' strip is only about 1/16" thick t' start.

Finishing:
Odd'l provides several skins that you can download, includin' a blank one. Ahoy! I finally decided on 'T' Point', me hearties, which is themed like t' classic cone rocket kit o' t' same name. Avast, me bucko, me proud beauty! I printed three copies o' the template and sealed them with a clear coat before starting. T' instructions say t' use spray glue. I dread usin' the stuff, me bucko, but it is about t' only choice for plain paper like this. Aye aye! I was pleasantly surprised that t' skins stayed on t' rocket and nay t' builder. Arrr! Begad!

Overall, this be a fun and slightly challengin' build. Begad! I'm happy that Chris's parts were so precise. Ya scallywag! Everything fit as advertised and t' skins are nice. Begad! I'd suggest tweakin' t' steps t' bevel-before-joinin' and t' cut t' launch rod hole before assemblin' t' body. Avast, me proud beauty!

Construction Rating: 4 out o' 5

Flight:
Prep is conceptually simple - fold and pack streamer, install motor by tapin' it t' t' lower motor tube, install igniter, me bucko, and launch. I found that packin' t' streamer and gettin' t' motor t' stay in place took a tad o' fiddling. Ahoy! My main concern prior t' launch was t' shock cord attachment. Will it hold? Will t' exposed elastic get burned by hot gasses trapped in t' base?

Well I flew t' Wedgie twice. I used Quest Q2G2 igniters, me bucko, shiver me timbers, me hearties, which are nice because t' long leads make it easier t' connect the clips. Avast!

It was quite windy for t' flight on a Quest 'long burn' C6-3. It weather cocked a lot but still attained a nice altitude. Arrr! Ejection occurred as planned and it recovered well. T' only damage, shiver me timbers, if you will, matey, was t' tip o' one o' the skins peeled back as it poked into t' sod. Arrr! Arrr! This be easily fixed with some cellophane tape. Begad! Aye aye! In fact, I recommend you add some preemptively.

I flew it again on a Quest B6-4. Avast! Well, blow me down! T' winds had died down a bit and t' boost was a lot straighter. Recovery be a bit late but was still in plenty o' time. Ya scallywag! This time, matey, t' crepe streamer be singed a bit. It turns out that I didn't use a square o' waddin' as directed in t' instructions (it's even underlined for emphasis). Aye aye! D'OH. Avast, me proud beauty! Ya scallywag! I guess that's what happens when you read, build, put on shelf for a couple o' weeks, and then rush t' t' launch.

Flight Rating: 4 out o' 5

Summary:
I love oddrocs and I like t' way this one flies. Ya scallywag! Its prep is easier than a 3/4FNC in some ways (no wadding) and harder in others (more dexterity required). Avast, me proud beauty! Well, blow me down! T' only down side I see is that t' streamer may need to be replaced after several flights (or maybe nay if you follow directions).

Overall Rating: 4 out o' 5

    A flying pyramid odd-roc with plenty of skin/decorating options... Components I'll take the easy road and just post a concurring/second opinion to Dick's thorough review. I purchased my kit in the fall of 2011, and the components have not changed. /h2 This is definitely not your simple 3-fin model, so reading the fairly good instructions is a must. I would ...

Thanks for the great review Dick! As with most Odd-Rocs, it is best to fly them in calm or low wind conditions. We do recommend flying the Wedgie with the Estes C6-3 engines. We don't recommend the Quest C6-3 in the Wedgie. The Quest C6-3 is a longer burning, lower sustained thrust engine. The Quest C6-3 has its place but not in a higher drag Odd-Roc like the Wedgie. In regards to the streamer singe, the instructions do say to drape a square of wadding over the rolled streamer.

You're welcome and thanks again for the opportunity to build and fly it! I actually don't think the Quest C6-3 is that bad. It is very common for saucers, cones, etc. to weathercock a bit and it was very windy for the first flight!. It is not like it was a scary flight or too low an ejection. However, it may be safer to at least be on record about the issue.

Quote: "The shock cord is attached to the inside base with a strip of balsa that is provided." The shock cord attachment strip is actually Limewood. While it looks like balsa, it is much stronger. After dozens of Wedgie flights, I have yet to have the Limewood strip pull off or fail.

I agree after it was attached, it seems plenty sturdy. If I had known it was limewood I might have used it to stir my rum and coke instead! (P.S., Typos on the review have been fixed.)
