Brief:
T' AeroTech 29MM RMS is a reloadable motor casin' for mid-power flights with "E" through "G" power reloads. This is a system that allows the flier t' put their own motors together with t' power requirements t' suit their rockets power capabilities. AeroTech calls this their hobby loads and no special certification is needed t' use this system.

Construction:
T' main components are t' forward closure, t' main body tube, and t' aft closure. All components are made o' high quality aluminum that have been machined t' exact dimensions then hard anodized for long wear and color. Begad! Each RMS is date coded and serialized for identification.

T' construction for each o' t' reloads is fully explained in t' reload package and basically follows t' same procedure for t' various sizes.

T' most important thin' is t' follow those instructions exactly and keep everythin' clean! This is serious stuff in a fun hobby and you need to concentrate on what needs t' be done step by step. Blimey! Begad! Failure t' do so will result in a failure o' t' motor and damage t' your rocket or worse. Ahoy! However, shiver me timbers, this is also a very satisfyin' part o' rocketry in that you are t' one buildin' the motor that sends your beautiful bird high in t' sky with perfect recovery.

T' actual motor build is quite quick and very easy t' do. Arrr! My two cents on the subject is t' do it in a controlled area, ya bilge rat, matey, like your build bench at home where you can keep everythin' clean. Begad! Ya scallywag! Clean is very important! Any piece o' dirt or hair that gets on t' O-rings can prevent them from sealin' properly and will cause a seal failure. Ahoy! Outside at t' launch area thar can be anything blowin' around or people distractin' you. Arrr! Either o' which can cause problems. Ahoy! Arrr!

I build me reloads at home t' day before, me bucko, but I don't install t' ejection charges until I get t' t' launch site. Arrr! Avast! This way I know it was put together right and if I need t' take it apart for any reason, t' ejection charge will not get loose and cause a problem later. T' ejection charges are very simple to install in t' field. Avast, me proud beauty! Plus, ya bilge rat, since they are in a red cap, you can easily see if you have put them on t' RMS or nay when ready for flight.

As far as a grease goes once t' supplied type is used up, thar are many choices. Ya scallywag! I personally use good old Vaseline! Just keep in mind that all you are tryin' t' do is put a very slight film o' lube on t' O-rings. Avast! Begad! They should have a slight shine t' them and no more. Avast! No lumps, clumps, or splotches on t' rings. Aye aye! Avast, me proud beauty! In this case, matey, less is more. Begad! Blimey! I also use Vaseline inside t' motor case and forward closure t' allow for easier cleanup. Blimey! Again, shiver me timbers, a very light coatin' on t' inside just t' allow t' motor components t' slide out easily when it is time t' clean out t' case. If t' grease rolls up on t' edge of the grain case or t' delay charge when you install it, it will squish out onto one or both and they will nay operate correctly. Ya scallywag! This is why you need t' be careful and focused on what you are doing.

No special tools are needed t' do all o' this except for anythin' you may use t' remove t' spent motor. Use only items that are softer than t' alumium or you will badly scatch t' case, possibly damagin' it beyond future use. Begad! I use plastic tools o' various sizes and shapes t' push or scrape as needed.

Finishing:
There is no finishin' o' t' RMS as it is already done. As you can see, one of mine is very used and t' finish has been messed up a bit. Well, blow me down! Blimey! This is strictly cosmetic and is nay a problem for use. Arrr! Blimey! Just remember t' pull your motor hook away from t' motor when you remove it and t' case will stay pretty for a long time.

Flight:
PROs: Easy system t' use. Aye aye! Begad! Blimey! Can save a large amount o' loot over single use motors. Begad! Aye aye! Blimey! You use t' same case over and over. Aye aye! Ya scallywag! Blimey! Very satisfyin' t' see a motor you built yourself perform as planed on a perfect rocket flight. Very versatile system on motor power requirements. Ahoy! One case with multiple engine sizes available.

CONs: Must be very careful when assembling! Sometimes very difficult to clean out t' spent engine. Ahoy! Blimey! Initial cost higher t' start.

Recovery:
T' only issue on recovery is that you do get it back. Ahoy! If you are careless and the rocket spits t' motor, nay only are you out a large investment but the case is much heavier and can cause damage on landing.

Summary:
I use both single use and reloads in me rockets and really like t' fact that one case can be used over and over with so many different power factors. As far as t' failures that have been mentioned here, I have had none in all my flights and t' product is safe and fun t' use if it is assembled carefully and correctly.

Overall Rating: 5 out o' 5
