Brief: Large but not chunky payloader. Ya scallywag! Blimey! Begad! Blimey! Lots o' room.

Construction: Quality; have only seen this one boxed. Arrr! I prefer t' boxed ones - any damage on t' inside is likely t' be visible on the outside. All parts present. Ahoy! None broken.

Clear and cardboard tubes, lots o' plastic parts includin' transition, motor mount and fins. Well, blow me down! Ya scallywag!

Instructions: Easy t' follow, matey, ya bilge rat, usual decent illustrations in good order. No templates needed. Aye aye! Aye aye!

Ease o' build: Do make sure t' pay attention t' t' lug alignment when gluin' t' coupler. Just makin' a tip on t' shock cord does nay ensure easy insertion into t' coupler. Ahoy! After fightin' with mine, I ended up usin' a floss threader which worked great. Begad! Aye aye! Alignment is good for fins and tubes. Ya scallywag! Blimey! Fit is good and straight. Transition is very loose and t' nose cone is extremely tight. Pretty sturdy but can see t' fins snappin' easily if it lands right. Avast! Blimey!

No special tools needed. Well, blow me down! Avast, me proud beauty!

Finishing: PROS: There is no finishing which is occasionally nice. Ahoy! Ya scallywag!

CONS: A constant gripe about Estes' decals, thar be only one for every other fin.

Construction Rating: 3 ½ out o' 5

Flight: Easy prep as with most D motors and large tubes. Waddin' needed and t' kit uses a twist-loc retention system. Ya scallywag! Blimey! Begad! Blimey! Blimey! Blimey!

On a D12-5, matey, t' flight was slow, arrr, low and okay. Begad! Don't know if t' slight veerin' was due t' t' wind or t' payload. Ya scallywag! Avast!

One might want t' leave t' nose cone fairly tight, matey, as me son's hot wheels popped it off on t' first flight.

Recovery: Parachute. As with most Estes models, it needs a longer shock cord. No damage. Avast, me proud beauty! A little too much driftin' for my taste. Cut a small hole in t' 24" parachute but don't go down t' an 18" 'chute. Avast, ya bilge rat, me proud beauty!

Flight Rating: 4 out o' 5

Summary: PROS: Nice t' have another big one around and a payloader at that. Begad! Good flyer. Arrr! Blimey!

CONS: As some have said, t' Sidewinder is "under leveled", shiver me timbers, this on is way "over leveled". Begad! Blimey! Why it's nay an E2X I have no idea. Begad! Overall assembly was no more difficult than t' Stingray or Skywinder.
