This review is for t' 2010 EMRR Challenge "Two on One" review.
Duane Boldt and Alan Boldt contributed t' this review.
This 26.5" 2-stage rocket is purple and yellow with cool decals. Aye aye! It is easy t' build and thar are nay many parts. T' Mongoose has plastic, one-piece fin units on both t' booster and sustainer.
PROS: This kit makes a nice fast kit t' build with school classrooms or school rocketry clubs. It is long enough t' satisfy t' 24"+ requireement for t' NARTREK Cadet Mercury Level and also t' fly t' multi-stage flight in t' later Cadet level. Arrr! It was easy for us t' build completely with thick CA glue.
CONS: T' only two cons are that t' body tubes are nay very strong and can be crushed if you are nay careful. Begad! Also, if you break any o' t' plastic fin sets, they are difficult t' repair. Most glues, even plastic cements, ya bilge rat, don't work well on them.
T' instuctions are typical Estes instructions and are easy t' follow. We were buildin' ours with a group o' students and used thick CA glue from LongJonRocket.com t' speed things up. Well, blow me down! Since we used t' CA, we were havin' t' wait for t' glue t' dry more than 10-15 seconds before movin' on t' t' next step.
1. Well, blow me down! T' booster is assembled with t' short purple body tube, and engine tube, engine block rin' and an adapter tube.
2. T' upper stage involved a similar process with t' longer purple body tube and similar parts.
** One thin' you need t' be careful o' is gluein' t' engline block rin' in t' correct position in t' booster and sustainer. Avast! It goes t' t' behind where t' motor will be in t' booster and forward o' t' motor space in t' sustainer. Arrr! We had t' "undo" one or two o' t' engine block rings. Avast! Just follow t' instructions and you will be fine.
3. Blimey! We marked t' line for t' launch lugs before installin' t' sustainer motor mount/fin assembly. Then glued in t' motor assembly into t' sustainer body tube.
4. We marked for t' launch lug possitions along t' line drawn in step 3 and then scraped just a little paint off t' tube at t' marks. We then glued on t' launch lugs.
5. We also used CA t' glue t' nose cone parts together,
6. We actually used a hot glue cannon for t' attachin' t' "3-fold" shock cord mounts inside t' body tube. Ahoy! Blimey! This saves some mess and works well as long as you glue it good and while t' glue is still hot and liquid. (We have only ever had one come apart and that is when a rocket a much too short delay and t' nose cone came off while it was still travelin' very fast.)
7. T' parachute was tied t' t' nose cone mattachment point along with t' loose end o' t' shock cord.
There you go. Begad! A very fast build in one short session even with a group o' kids. T' rocket performs well and as long as you do nay crush t' tubes, as Alan mentioned, arrr, t' rocket wil make many successful flights.
There really isn't any finishin' other than applyin' t' decals. they are typical self-adhesive decals. T' kids like them a lot and had fun puttin' them on. Ahoy! Nay quite as nice as waterslide decals, but easy t' apply.
Construction Rating: 4 out o' 5
We mostly flew B6-4 motors for single stage flights and B6-0 / B6-6 combos for two stage flights. T' rocket performed great. Well, blow me down! T' field we were lauchin' at is great for up t' B motors. Well, blow me down! C's and multi-stage sometimes get devoured by t' rocket eatin' trees or are carried by wind t' a make some other lucky kid happy. Ya scallywag! Overall great performance on our flights.
PROS: Very easy t' assemble parachute. Avast! No damage if packed correctly. Blimey! Lands nay t' far from pad in low wind conditions.
CONS: T' body tubes were kind o' flimsy and sometimes were crumpled on landing, me hearties, if parachute didn't deploy fully. Avast, me proud beauty! Blimey! One student, launchin' with us, arrr, did loose their sustainer on a multi-stage flight with too much wind.
Flight Rating: 5 out o' 5
PROS: T' Mongoose is a simple t' build kit that works good for classroom building. Avast! It is easy enough that it can be built quick and with little hassle when workin' with larger numbers o' kids. Ahoy! It also works for several o' t' NARTREK Cadet required flights includin' Level 1 build with plastic fins, 24"+, and Multi-Staged.
CONS: T' tubes are a little flimsy and t' paper can sometimes peel. Treat tube ends with thin CA before buildin' t' keep them from unraveling.
Overall Rating: 4 out o' 5
T' Mongoose is a simple rocket t' build and flies well.
