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

Construction:
T' rocket uses a 15 inch long BT-60 body, ya bilge rat, ya bilge rat, 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), one 5/16 x 5.5 inch launch lug (the one you really use), three feet o' 1/4 inch sewin' elastic, and an old nylon flare chute, and a positive motor retention device o' my own design.

T' rocket went together well. Begad! Ya scallywag! After all, it is pretty much a standard 3FNC model. Aye aye! T' fins were t' biggest part of t' project (other than t' finishing) and were shaped usin' me trusty Dremel tool. Ahoy! Arrr! 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. Avast, me bucko, me proud beauty! It's nay quite as strong as through t' wall fins but it's still pretty strong. T' motor mount was glued in usin' far more epoxy than was probably needed, arrr, but I wasn't takin' any chances. Blimey! Begad! T' shock cord was mounted usin' t' old Estes method but with a whole lot o' epoxy thar too. Begad! Ya scallywag! I wanted t' rocket t' have a "low power" look so I put on standard Estes launch lugs like were on t' original. Avast! However, I then put on t' heavy duty lug on the other side so it could actually take off without whippin' t' rod like crazy. I wanted t' be real sure t' motor stayed in place, 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. Begad! Changin' t' motor takes a little time, me bucko, 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 was painted usin' black and yellow H2O paint by Krylon, shiver me timbers, which doesn't make me break out in hives. Ahoy! Blimey! Ya scallywag! Blimey! It was fairly easy t' mask off t' one black fin and top black part. Avast, me proud beauty! Blimey! On t' original, shiver me timbers, only t' nose cone is painted black. Since me parts are nay exactly scale, shiver me timbers, 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, and that be it! Blimey! Now I only had t' get up t' nerve t' fly it. Begad! Blimey! Aye aye! Blimey!

Flight:
I decided t' fly t' Maxi-Scamp for t' first time at NSL 2006. Avast, me proud beauty! 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. If you've never flown a Roadrunner, me hearties, arrr, ya bilge rat, you should. Begad! They're maxed out and quite frankly scream. Avast! 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! I be pretty sure I wasn't goin' t' see it again. Arrr! Ya scallywag!

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... Well, blow me down! Soon I lost sight o' it completely. Begad! Aye aye! I felt a little stupid for puttin' that much motor in it for its first flight, but everyone had gotten quite a show. I just hoped I had caught it with me camera. Well, blow me down! 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, about a mile from t' range head. Arrr! It be especially cool because all I caught with me camera be a bunch o' smoke.

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

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