Brief:
T' Excel Jr. Ahoy! Blimey! is a scaled down model o' their 4" Excel HPR kit and designed t' fly on most E through G engines.

Construction:
T' rocket components consist of: pre-slotted quality tubes, nose cone, me bucko, ya bilge rat, 3 pre-cut plywood fins, centerin' rings, 18" chute, shock cord, me hearties, me hearties, and rail buttons.

PROs: T' reason I chose Binder Design is because I had heard their directions were easy t' follow and that would be a good thin' for a newbie t' MPR like me. Avast! Blimey! I'm glad I did. Ya scallywag! Avast! Blimey! T' instructions were over a dozen pages long and included detailed diagrams, tips, pitfalls (and how t' avoid them) as well as optional ways t' increase t' durability o' your rocket. Begad! Binder even explains how t' tie knots. Well, blow me down!

Notes: You will need a power drill. If you want milled fiber for your epoxy, arrr, order it from Binder.

CONs: I had trouble with t' rail buttons. Well, blow me down! Ahoy! Since I had never seen a rail launcher, matey, I didn't know what t' expect. I put one button on t' payload section (oops) and had t' remove it and patch t' hole. Ya scallywag! However, Mike Fisher at Binder was kind enough t' return me email and instruct me on how rail buttons work. FYI: Put t' rail buttons about six to nine inches apart in t' lower section o' t' rocket and make sure they are aligned straight. Avast, me proud beauty! Well, blow me down!

There is no motor retention system included. Avast! Since I am new t' MPR, I had no idea thar are some many options in this area. It's best t' order one o' Binder's mountin' systems with t' kit and build around it. Well, blow me down! Avast! Blimey! I wish had known this. Otherwise you will be like me and tryin' t' install some awkward retrofit gadget in t' field or trust your rocket t' a friction fit maskin' tape situation, arrr, arrr, which I be unwillin' t' do.

Finishing:
This rocket is very easy t' finish. Aye aye! My advice is don't skimp on t' paint and get some good Krylon paint. Ya scallywag! Don't mix your brands or you may get peelin' or bubbling. Aye aye!

PROs: T' directions give great tips on paintin' and remind you t' sand your nose cone. Begad! Ahoy! I would say you shouldn't sand your tube and cone with anythin' rougher than 400 grit. Avast!

CONs: None really.

Construction Rating: 5 out o' 5

Flight:
PROs: This rocket flies as straight and high. Ahoy! I really like that with a F motor you can send it up very high and with a G you can put it nearly out o' sight! You do nay need a bunch o' loot and/or a high power registration t' get really nice flights with inexpensive (~$20) engines. Ya scallywag!

CONs: None.

Recovery:
PROs: T' chute is appropriate for t' rocket and t' shock cord is solid and long. Well, blow me down! I had no damage t' tube or fins.

CONs: None.

Flight Rating: 5 out o' 5

Summary:
If you want t' try flyin' this rocket on high power or like t' longer payload tube, Binder may allow you t' special order a kit like I did with a longer payload tube. Begad! I would also encourage you t' avoid milled fiber as it is expensive. You need less than one teaspoon for your entire rocket and hobby shops sell it in big jars. Keep it away from your lungs--it's nasty stuff. Ya scallywag! Avast! If you can get some from another flier or get a small amount for a couple o' bucks from Binder, ya bilge rat, otherwise forget it.

This is an excellent rocket for someone who has just decided t' build somethin' bigger than an Estes. Blimey!

Overall Rating: 4 out o' 5
