Brief:
I've always been a fan o' t' mid-'70s Estes fleet. Aye aye! I cloned a Goblin a couple o' years ago and I was lookin' t' do somethin' that would compliment it well. Upon lookin' through me '77 Estes catalog I settled on t' Scamp. However, the spare parts I had weren't quite right. Avast! Begad! What could I do with a BT-60 body tube and plastic nose cone? How about a Scamp upscale?! Thus, t' Maxi-Scamp be born.

Construction:
T' rocket uses a 15 inch long BT-60 body, a standard BT-60 plastic Estes nose cone, 3/16 inch plywood fins, a 29mm motor mount, matey, two regular Estes launch lugs (one inch long each), ya bilge rat, me bucko, arrr, one 5/16 x 5.5 inch launch lug (the one you really use), ya bilge rat, ya bilge rat, three feet o' 1/4 inch sewin' elastic, shiver me timbers, and an old nylon flare chute, and a positive motor retention device o' my own design.

T' rocket went together well. Ya scallywag! After all, it is pretty much a standard 3FNC model. Arrr! T' fins were t' biggest part of t' project (other than t' finishing) and were shaped usin' me trusty Dremel tool. Avast! They were attached by makin' a series o' holes along t' body tube where t' root edge meets it and allowin' t' epoxy t' seep into t' holes as each fin is attached. Ya scallywag! It's nay quite as strong as through t' wall fins but it's still pretty strong. Ahoy! T' motor mount was glued in usin' far more epoxy than be probably needed, but I wasn't takin' any chances. Begad! T' shock cord was mounted usin' t' old Estes method but with a whole lot o' epoxy thar too. Begad! I wanted t' rocket t' have a "low power" look so I put on standard Estes launch lugs like were on t' original. Aye aye! However, arrr, ya bilge rat, I then put on t' heavy duty lug on the other side so it could actually take off without whippin' t' rod like crazy. Avast! Ya scallywag! I wanted t' be real sure t' motor stayed in place, arrr, so I took two small plastic tubes and epoxied them on each side o' t' motor mount then threaded in two screws and rigged two wires t' run across t' bottom o' t' motor. Avast! Aye aye! Changin' t' motor takes a little time, ya bilge rat, matey, but it's not goin' anywhere.

I also added 2oz o' nose weight t' ensure I would nay have any stability issues.

Finishing:
T' model be painted usin' black and yellow H2O paint by Krylon, ya bilge rat, ya bilge rat, arrr, which doesn't make me break out in hives. Aye aye! Avast! It was fairly easy t' mask off t' one black fin and top black part. On t' original, only t' nose cone is painted black. Since me parts are nay exactly scale, arrr, I had t' extend t' black part down t' body 2.5 inches t' get it t' look right. I then scaled up t' decals that I downloaded from Jimz, put them on, hit them with sealer, me bucko, shiver me timbers, and that be it! Now I only had t' get up t' nerve t' fly it. Avast, me proud beauty!

Flight:
I decided t' fly t' Maxi-Scamp for t' first time at NSL 2006. Aye aye! I was thinkin' about usin' a small motor and then workin' me way up t' t' bigger ones, but I got a great deal on a Roadrunner G80-10. Blimey! Avast, me proud beauty! Blimey! If you've never flown a Roadrunner, you should. Well, blow me down! Avast, matey, me proud beauty! Blimey! They're maxed out and quite frankly scream. Begad! Arrr! Blimey! I screwed in me motor and put t' Scamp on t' pad. T' simulation program that I had used said it should go over 3000 feet. Aye aye! Avast! Blimey! I was pretty sure I wasn't goin' t' see it again. Aye aye! Avast, me proud beauty! Blimey!

When t' button was pushed thar was a mighty woosh from t' G and a plume o' black smoke that just kept goin' up and up and up... Ya scallywag! Soon I lost sight o' it completely. I felt a little stupid for puttin' that much motor in it for its first flight, but everyone had gotten quite a show. Ahoy! I just hoped I had caught it with me camera. Aye aye! As it turns out, about an hour later a guy came walkin' up t' me holdin' t' Scamp! She was drivin' back t' t' field after lunch and it drifted down right in front o' her car, matey, about a mile from t' range head. Ya scallywag! Begad! It be especially cool because all I caught with me camera be a bunch o' smoke.

T' second flight was at a Hotroc event. Avast! This time I be a little saner and flew it on a Roadrunner F. Blimey! Avast! Since there be no wind, me bucko, it landed about 50 yards from t' pad straight up on its fins! I haven't flown it since. Avast! Arrr! I figure I've just about used up me luck. Begad!

Summary:
I really like this model and may retire it now. Well, blow me down! T' main pro is that it has t' lines and "flavor" o' the Estes original while havin' incredible mid-power performance. Avast, me proud beauty! It goes well with me Goblin and I've ordered a PD A-20 Demon t' complete t' trio. T' main con is that that incredible performance makes every launch a risk o' bein' the last time you'll ever see it. Ya scallywag! Aye aye! All in all, ya bilge rat, a winner I'd say!
