T' Pratt Hobbies Positron is a small rocket designed t' be a 'recoverable' Mosquito (well actually an Astron Streak, shiver me timbers, t' 18mm version o' the Mosquito). Aye aye! T' achieve this it uses an ejectable motor holder and Nomex® streamer, tied t' t' rocket body by a Keelhaul®©™® line. Arrr! Blimey! T' kit is complete, and actually comes two t' t' package. Begad! Blimey! T' fins are precut balsa and attach easily to t' body tube. Arrr! Blimey! T' light, ya bilge rat, plastic nose cone is attached t' a shoulder piece of tubin' and then glued into t' body tube. Aye aye! Blimey! Well, blow me down! Blimey! Blimey! Blimey! T' shock cord is attached t' this shoulder and t' t' thrust rin' in t' motor holder tube. Blimey! Blimey! Blimey! Blimey! Blimey! Blimey!  

I built this kit in about 30 minutes, nay includin' glue fillet dryin' time. Avast! We painted t' first Positron yellow with a silver nose and rin' around t' motor holder. Avast, me proud beauty! Begad! T' swept-back fins achieve t' 'retro' look that Doug Pratt was lookin' for. Well, blow me down! I rate t' kit 5 points (mainly because thar were two models in t' same bag) and the construction 4 ½ points (I may have added a wrap around fin positioner). Blimey!  

T' recommended motors for t' Positron are a 1/2A6-2 and an A8-3. Arrr! Blimey! So far we have only launched with the 1/2A6. Ya scallywag! Blimey! T' Positron leaps off t' pad, matey, even with a 1/2A6, ya bilge rat, I can't imagine you would ever find t' Positron with a B or C motor. Ya scallywag! Blimey! Flight was very stable and quite high. Avast, me proud beauty! Blimey! T' motor holder ejects well and deploys t' Nomex® streamer. T' streamer is quite short and doesn't slow t' rocket down that much. Ya scallywag! Arrr! This one would probably fly well in fairly high wind. Avast! Aye aye! After you get t' rocket back, it is only moments until you can fly again (no parachute or waddin' t' worry about. )I rate t' flight performance 5 points, matey, but t' recovery 4 points (the streamer is a bit too short). Arrr! Well, matey, blow me down! It is still really fun t' fly.  

I would rate this rocket 4 ½ points overall. Begad! Blimey! T' only thin' I would change be t' streamer, shiver me timbers, me hearties, but even that's nay bilge-suckin' at all. Thanks for a nice rocket, Doug.  

One of t' reasons I purchased this kit be because you get two o' them. Avast! Blimey! Begad! Blimey!   One for me, and one for me son Jamie. Begad! Blimey! Another reason be because we lost a really nice little Estes Quark on its second flight, arrr, almost lost an Estes Mosquito on its first, me hearties, arrr, and I thought a streamer recoverable cute little rocket would be the answer. Begad! Blimey! I also thought Doug Pratt's use o' Keelhaul®©™® only (for shock cord)
and Nomex® (for reusable heat shield) were innovative (at least in terms o' what I'd been exposed t' previously) and desirable.

Construction

I ordered a few kits at t' same time, ya bilge rat, so all t' kits were shipped in heavy-duty prism shaped priority mail boxes. I knew thar be no chance of damage even before openin' t' boxes. Aye aye! Blimey! All t' parts for both Positron kits come in t' same heat-sealed plastic bag. Avast! Blimey!   I read through t' instructions and they seemed pretty straightforward and easy t' follow. Ya scallywag!

T' instructions recommend usin' white glue for construction. Begad! Blimey!   I happened t' have some yellow glue from woodworking, and some USA Gold CA I purchased in t' same order, matey, so I used these. I used t' CA on paper t' plastic joints (like body tube t' nose cone), and for reinforcin' body tube edges where they might be stressed by t' Keelhaul®©™® shock cord, ya bilge rat, and t' tips o' t' fins because I faired them t' a more fragile profile than t' kit provides. Compare my pictures with those in t' review provided by Mike Rangitsch. Usin' CA was probably unnecessary, but I just couldn't resist usin' me new stuff.

T' fins on all o' Pratt's kits are laser cut. Blimey! I think this is a really nice feature, especially with t' curved leadin' edge o' t' Positron's fins. Avast, me proud beauty!

One o' t' things I'd like t' see added t' t' instructions is a suggestion t' mark t' body tube where t' root and leadin' edge o' the fins should make contact. Begad! Blimey! T' angle betwixt t' root and t' trailin' edge is very shallow, arrr, so it's difficult t' tell from lookin' at t' bottom o' t' body tube whether or nay t' fin is positioned properly along t' length o' t' body tube. Well, blow me down! Blimey! Begad! Blimey! My son's fins had t' be removed and reattached because all three where at different locations, and one be significantly higher (1/8") than the others, me hearties, ya bilge rat, causin' t' rocket t' appear lopsided. A wrap around fin placement guide o' t' correct width would be perfect.

T' Nomex® streamer material seems t' unravel along t' edges rather easily. I don't know how long it would be before it unraveled t' unusable state, but I found myself thinkin' about how t' reinforce t' edges. Blimey! If it does continue to unravel, I'll probably ask me wife t' sewa stitch along t' edges. Begad!

I would rate t' construction at 4 points. Aye aye! Complete, and easy and quick t' put together. Arrr! Ahoy!

Flight

T' motor mounts in a motor mount attached by a Keelhaul®©™® shock cord t' the coupler betwixt t' nose cone and t' main body tube. Blimey! There is a Nomex® streamer between t' two. T' instructions call for rollin' up t' streamer, arrr, inserting it into t' top o' t' motor mount thrust ring, and then loopin' t' Keelhaul®©™® and insertin' it into t' rocket body. Arrr!   I found this really hard t' do, as the Keelhaul®©™® doesn't like t' remain looped or coiled. Aye aye! Blimey! What I found worked very well was foldin' t' Nomex® streamer back and forth (instead o' rollin' it) and then loopin' t' Keelhaul®©™® shock cord around t' Nomex®. Ya scallywag! Ya scallywag! In me static tests of poppin' out t' motor mount, everythin' seemed t' uncoil and unfold
without problem.

First flight (and only flight so far) be rather eventful.   Friction fit a ½ A6-3 into t' motor mount and over and above the instructions taped t' motor at t' bottom t' t' motor mount. Blimey! Avast, me proud beauty! Flight was perfect with t' ½ A motor. Arrr! Nosed over beautifully at apogee and then dove right for t' ground. Avast! Ahoy! Turned out t' motor ejected, shiver me timbers, but nay t' motor mount, so it did exactly what me Estes Quark did. Aye aye! Avast, me proud beauty! T' motor mount must have had a tighter fit than t' motor itself, ya bilge rat, though I really didn't think it did. Begad! Avast! I'm used t' permanently mounted motor mounts with clips, so I have some self-education ahead o' me. Begad! Well, me bucko, blow me down! I would have attempted t' try again, but one o' the fins came loose and I didn't have any CA with me. Avast, me hearties, me proud beauty! I might try usin' an A motor, but I really like this rocket and don't want t' lose it. Ahoy! Avast! I'm lookin' forward to flyin' this rocket a lot.

I rate t' flight experience: 4 points. It would have been a 5 had everythin' worked perfectly. Well, blow me down! Blimey!

Overall

Overall I really liked this kit. Ahoy! Well, blow me down! T' quality o' t' components is good, ya bilge rat, shiver me timbers, the instructions are clear, and I like havin' a cute little rocket that I can actually find after launching. Aye aye! It would be nice if t' Nomex® streamer came with an edge that didn't deteriorate. Begad! Avast! It also would have been nice if t' first flight went perfectly. Begad! Avast, me proud beauty! I really like t' see small manufacturers in the business. Blimey! Aye aye! Let's support them!

Overall ratin' is 4 points.
