Brief:
This is FlisKits' new model o' a cut-away rocket motor. It is designed t' be used as a classroom or science-fair demonstration model.

Construction:
T' kit consists o' a laser-cut sheet o' fiberboard parts, shiver me timbers, two body tubes, matey, a coupler tube and a sheet o' paper parts.

OK, shiver me timbers, ya bilge rat, I really wanted t' like this kit, arrr, but it be frustratin' and difficult from t' start. Avast! Well, blow me down! T' model is essentially two rocket body tubes cut in half and glued t' fiberboard "ribs." T' fiberboard be very weak and prone t' delaminating. Begad! Cuttin' t' parts free from t' laser-cut sheet be remarkably difficult. T' whole assembly was hard t' keep square and t' strips did nay line up with t' rings correctly. Begad! This design requires you t' cut the body tubes t' fit by hand, and I found it very challengin' in gettin' a clean, lengthwise cut in a body tube. Blimey! Blimey! Once everythin' was assembled, shiver me timbers, you have t' fill t' small voids in t' center o' t' nozzle with paper cones. Aye aye! Begad! T' fact that they supply you with three spares for each piece should indicate how challengin' this step can be. Once you get it lined up and glued in place, you again have t' hand-cut t' pieces t' fit. Aye aye!

I found this t' be an extremely challengin' model--far beyond t' average child's skill level for a science fair project and nay good for a teacher who is only casually lookin' t' make a classroom model.

Finishing:
T' finishin' o' this model was even worse than t' building. T' decal wraps that are shown in t' kit photos must be downloaded from t' FlisKits website and printed onto full-size label paper. Avast, me proud beauty! Ya scallywag! I ended up goin' t' three stores before I could find t' right kind o' label paper and then t' label paper cost more than t' kit! When I printed t' labels, I be surprised t' find they do nay cover t' entire model, but leave t' ends and top sides uncovered, me bucko, me hearties, so you have to try and match t' labels with paint. Then, when I went t' apply them, they are nay t' same size as t' finished model and leave gaps around t' edges. I really think t' labels should have been included in t' kit and should completely cover t' model. I was very disappointed with t' finished result. Aye aye! Perhaps someone more adept at computers could resize the labels t' fit better.

Construction Rating: 2 out o' 5

Summary:
I was very disappointed in this kit. I feel t' lack o' labels and t' poor fit make it incomplete. Avast! It builds into far too fragile a model for passin' around a classroom. (One rowdy kid could easily crush it--the paper parts are as sturdy as, matey, arrr, well, paper.) And at even 3 times normal size it is too small t' be seen by t' back row o' a class. Blimey! It might be useful in a science-fair display, but I think it is far too challengin' for most children t' build. Begad! (Maybe an advanced high-school student could tackle it?) And t' finished product isn't really that great lookin' t' use. Begad! Really, it's only savin' grace is that thar be nothin' like it out there.

Overall Rating: 2 out o' 5

    ( Contributed - by Chan Stevens - 02/07/09) Brief: This is a neat display of the interior of a model rocket motor, and at 3:1 upscale, it's large enough to use in a typical classroom presentation. Construction: This kit comes packed in a typical rocket baggie with color header card and contains the following parts: BT-70 tube Laser-cut cardboard detail sheet ...

    ( Contributed - by Hans "Chris" Michielssen - 02/01/09) Brief: I "won" this kit on a rocketry forum. A build thread hosted by Powderburner followed the steps of the assembly. After the last assembly post, the host asked the readers to find the mistake in his build. If you found the error you would receive a Cutaway Engine Kit as a prize. I read through the ...

    ( Contributed - by David Landgraf - 01/02/09) Brief: If you have ever been at a loss for a giant version of a model rocket motor to use as a teaching aid to hold up in front of a class, this is your ticket. This little kit provides a good illustration of the internal parts, gives you a model in a good, usable size, and is easy to assemble in a couple hours of total work time. It ...

The cut-away motor model is generous in depicting the technology for a typical commercial black powder motor by displaying a converging/diverging clay nozzle. Most commercial BP motors have only a diverging nozzle.

Jim, Jim Flis here. I am terribly sorry that you had such difficulty with this kit. To address some of your concerns, I can offer the following:
* This model is not aimed at young modelers and is certainly not what we would call a beginner kit. You are correct that there are challenges in building it.
* The cost point we were aiming for (less than $10) precludes us from including a label with the kit. A free download label is easy to provide and is only an available option. the builder is free to finish it as they choose.
* I would be most interested in working with you offline as your comments about difficulty in removing laser cut parts and a flimsy end product indicate that you may have gotten some defective parts as you shouldn't be having such problems. Feel free to contact me if you would like some resolution in this regard. Thank you for your review. As you know we value all feedback and negative feedback helps us identify things that need attention!
