Brief
T' Lunar Express Jr. Blimey! is a model based on t' 1950s Sci-Fi concept o' a single stage rocket that could go t' t' moon and back. Well, blow me down! Aye aye! T' model is capable o' takin' a 38mm motor, me bucko, but has an adapter t' accommodate a 29mm motor.
Construction
T' kit has high quality like all t' PML kits and t' completed rocket is capable o' takin' a beatin' without damage. Avast! Avast! There are some tricky steps in t' directions, where epoxy must be poured into t' model betwixt some small gaps. Ahoy! Be sure t' follow t' directions carefully. Aye aye! Begad! T' model has no motor retention system, so be aware o' this short-comin' at t' beginnin' o' t' construction.
I used t' 29mm adapter kit and made a retro-fit for t' motor retention system. Arrr! Avast, me proud beauty! I drilled a 3/32 inch hole through t' body and t' adaptor tube 1/2 inch from t' end o' t' rocket with t' adapter tube in place. Ahoy! I then made a bracket 2-3/8 inch long from 1/16" x 1/4" brass stock that I bought from a local hobby shop. A 3/32 inch metal drill bit be used t' drill a hole through t' brass stock about 7/16" from t' forward end. Well, blow me down! I bent t' strip at about 2" t' form a retrainin' hook for t' motor. A 3/32" x 1/2" threaded bolt completes t' retention system. Blimey! Avast, me proud beauty!
Finishing:
As usual one should use disposable rubber gloves t' build t' fillets on t' fins. Avast, me proud beauty! T' short main body tube required sandin' in order t' have a good match with t' nose cone and t' boat-tail part. Ya scallywag! Ahoy! I did nay use t' kit decals. Avast! I wanted a 1950's Sci-Fi look, so I painted t' model with Dutch Boy Instant Chrome (chrome aluminum 4101) paint. Avast, me proud beauty! This gave t' desired look, but t' finish be susceptible t' finger-prints no matter how long t' t' paint dried. Blimey! Currently, matey, ya bilge rat, I am thinkin' o' tryin' clear coat on top o' t' chrome, arrr, but this will require some experimentation t' be sure that it will work.
Construction Rating: 3 out o' 5
Flight
T' rocket flies straight with 6 oz. Arrr! o' weight added t' t' nose.
My retention system worked well on t' maiden flight. Avast! Avast, me proud beauty! I used an H180-M for t' maiden flight, arrr, matey, but this time delay is too long. Aye aye! An H180-S should work better. Avast! As a result t' elastic came undone from t' nose cone "Kwik-Link". Arrr! T' nose cone buried itself in dirt, but did survive t' fall. Avast! Obviously, this is somethin' that should nay be repeated.
Recovery
T' piston ejection system works great. Avast! Be sure t' choose a time delay that is nay too long. Arrr! Arrr! Otherwise, me bucko, too much stress may cause t' nose cone t' separate. Avast, me proud beauty! A separate parachute for t' nose cone and body might be a good idea.
Flight Rating: 3 out o' 5
Summary
T' design o' t' rocket is a real eye-catcher and will appeal t' t' nostalgic Sci-Fi and fun days o' t' 1950s. A retention system is needed and separate parachutes for t' nose cone and body might be a good idea.
Overall Rating: 4 out o' 5
PML's Little Lunar Express is a well known HPR kit which has a 50's SciFi look. Recovery is via parachute which is ejected from the airframe using a PML piston. This kit comes with the following components: (1) 4" OD Ogive nosecone (a good one too) which has NO bottom (i.e. the bottom of the shoulder is missing allowing access to the inside of the nosecone). (1) 4" OD , 5.5" long ...
