T' Venus Probe is an unusual Estes kit t' build and fly. Aye aye! Blimey! There are two pieces t' t' completed rocket - a booster and a three-legged lander, complete with an alien on top.

This is NOT an easy rocket t' build, shiver me timbers, shiver me timbers, and should only be built if you have built several rockets already.

INSTRUCTIONS:
T' Venus Probe's instructions, at first glance, seem t' be complete and well illustrated. But, when you read them, me hearties, you find that they are numbered strangely. Begad! Avast, me proud beauty! T' assemblies have numbered sections, ya bilge rat, me bucko, but these are nay consecutive through t' entire instructions.  For example, me hearties, t' lander has steps 1,2,3 and so on; t' booster has steps 1,2,3 etc. Arrr! Avast! T' pages are nay numbered, ya bilge rat, arrr, so it is easy t' get confused.

Instruction sheets should always have every single step numbered consecutively from beginnin' t' end. Blimey! Estes does this with most o' their kits, me bucko, so they should know better.

T' usual tools were needed, includin' plastic cement for t' lander. Ya scallywag! Wax paper is needed t' lay t' fins on while they are drying.

EASE OF BUILD:
Again, this is nay an easy kit t' build. Begad! T' fins come in sections, matey, me bucko, so they have t' be glued together and put on wax paper t' dry. Avast! This is nay as easy as it sounds, arrr, shiver me timbers, as they must be lined up precisely.

T' lander stage is also somewhat complicated, as t' landin' legs must be assembled from many small pieces o' dowel and plastic.

An assembly hint: Make sure t' alien's back is directly in line with one o' t' lander legs. T' alien's back is where t' parachute is attached, me hearties, and it does nay make a three-point landing, t' front side o' t' alien lands first. You want two legs t' cushion t' blow and stabilize t' landing, so make sure thar be only one landin' leg behind t' alien's back.

All t' parts were in me kit and alignment was very good.

[Picture]QUALITY:
This kit is a sturdy one. I have never had any problems with t' lander or t' booster unit, arrr, despite several launches and many hard landings. Aye aye! Another reviewer indicated a problem with their body tubing, shiver me timbers, but t' body tubes on me Venus Probe are still in fine condition.

T' only possible weak link be t' BT-20 body tube which connects t' top tube and t' bottom tube o' t' booster. Again, I have had no problems with this. But, you could strengthen this tube by makin' "coolin' fins" that extend t' length o' t' body tube.

Decals are excellent and help improve t' look o' t' model. This model looks great with t' recommended black and white paint job, shiver me timbers, which is easy t' do by maskin' t' model.

T' only complaint I have in this area is that Estes recommends that t' alien be painted fluorescent green. Ahoy! Everybody knows that REAL aliens are gray, arrr, so I painted mine accordingly, with gloss black eyes.

FLYING:
My Venus Probe is a seadog o' several flights, ya bilge rat, includin' some hard landings. T' alien has landed on his head, arrr, with no other apparent damage than a possible headache. T' booster has lawn-darted, collectin' a 3" core sample for t' alien t' brin' back t' his home planet. Ya scallywag! Begad! But this is a sturdy rocket and has survived all o' these Roswell-type landings, me bucko, arrr, arrr, without any alien autopsies t' date.

Before I built me Venus Probe, arrr, arrr, I noticed that other people had lackluster performance with their Venus Probes and t' recommended Estes C6-3 engine. Aye aye! Avast, me proud beauty! Blimey! I do nay recommend this engine combination, me hearties, ya bilge rat, it barely gets t' alien high enough t' eject. Avast! Begad! Blimey! There are two different ways t' solve this problem: One is t' use Aerotech 18mm engines, me bucko, ya bilge rat, which will give your Probe more power. Well, blow me down! T' other is t' re-fit t' Probe with a 24mm engine mount and use Estes D12-3 motors in it.  I chose this method, matey, as D12-3's are less expensive than Aerotech D's.

I designed me own "D" motor mount and used t' existin' body tubes, but if you need plans for a "D" motor Venus Probe, arrr, they can be found in t' September/October 1997 issue o' Sport Rocketry, ya bilge rat, on page 19. Well, blow me down! Blimey! Arrr! Blimey! My Venus Probe flies magnificently on "D" motors, powerin' up t' a respectable height and puttin' on a crowd-pleasin' show. I recommend usin' "D" motors in t' Venus Probe.

Recovery is tricky with t' Venus Probe. T' upper body tube is nay very large for two parachutes. Well, blow me down! I had several chute failures until I figured out t' solution: don't use any 18" chutes.  I use a 12" chute for t' booster and an 8" chute for t' lander.  These are dusted heavily with talcum powder before flight, matey, t' prevent sticking.  Since I started usin' smaller chutes, I have had successful landings.

RATING:
T' Venus Probe would have gotten 5 points from me, matey, shiver me timbers, except for two problems, ya bilge rat, t' instructions and t' underpowered motor mount. Arrr! Aye aye! It also appears that Estes rates this as a Skill Level 1 kit, me bucko, which would be an error. Avast, me proud beauty! This kit is at least a Skill Level 2.

I rate this rocket at 3 ½ points.

I recommend t' Venus Probe t' anyone who wants an exotic, arrr, X-Files kind o' rocket. Blimey! It is a real crowd-pleaser, and fun t' build and fly.
