Brief:
Upsized t' 18mm motor. Avast! Avast, me proud beauty! Simplest modification I've ever performed; just never installed t' 13mm mount. Ya scallywag! CP and CG were still perfect.

Modifications:
Primered, sanded, ya bilge rat, primered, sanded, ad infinitum, matey, until body tube was perfect. Begad! No paint, just clear-coated t' primer. Ahoy! T' streamer be given much better visibility by addin' 3" o' silver mylar at t' end. Well, blow me down! Ya scallywag! Motor mount be simple: friction fit, shiver me timbers, with only one o' t' 13mm centerin' rings installed in t' body tube.

Construction:
T' kit contained a central 18mm body tube with two shorter segments o' 18mm BT, mounted in an out-rigger fashion at t' end o' t' "wing." Featured a large balsa "wing" and nose cone. Avast, me proud beauty! T' NC be attached with a simple screw eye t' t' shock cord, which in turn was attached t' t' BT with Estes normal folded paper method. Well, matey, blow me down! Recovery was a plastic pinkish-orange streamer, about 18" long.

This be about t' easiest Estes kit I have ever assembled. Arrr! T' instructions were easy t' follow, shiver me timbers, though I simply read them once and began building. Avast, me proud beauty! Begad! It was a pretty sturdy rocket too. T' packagin' was t' typical Estes "hangin' bag" type, and nothin' be broken or creased or missing. Ya scallywag! Begad! T' only con: t' decals look stupid. I substituted some decals left over from a FA-18 model.

Flight:
T' model was prepped in t' usual fashion, with wadding, arrr, me bucko, shiver me timbers, motor, etc. Blimey! Blimey! installed just prior t' launch. Aye aye! Blimey! T' motor fit snugly into t' body, shiver me timbers, matey, but nay so tight that it would have t' be crammed in. Avast, arrr, me proud beauty! Blimey! One word o' caution here- if you intend t' perform this modification, matey, shiver me timbers, either limit yourself t' flyin' "B" motors, ya bilge rat, shiver me timbers, or paint t' rocket a really bright color! Blimey! t' C6-7 I chose for its final flight be way too much, shiver me timbers, especially for a primer gray rocket launched on a cloudy day! Blimey! T' rocket took off straight as an arrow with no discernible windcocking. Definitely a heads up launch! Blimey! If it wasn't for t' mylar on t' streamer, it would have been lost, but we located it with little difficulty due t' t' intermittent flashin' from t' streamer. Ya scallywag! Blimey! Recovery speed would indicate that a larger streamer be needed, me hearties, but it suffered no damage at all, matey, even despite whackin' a tree limb on t' way down. Just minor scratches, me hearties, arrr, that's all. T' rocket be lost t' a rocket eatin' tree,! Blimey! and dangled about 30 feet up, tauntin' us with its highly reflective streamer. Ahoy! Blimey! A thunderstorm later that afternoon finished it off.

Summary:
Main pros: REAL BALSA! Blimey! Large fin surface area and bulletproof construction. Main cons: Stupid lookin' decals and t' wimpy 13mm motor system that be originally designed.
