(10/10/01) Apogee's Medalist composite motor offerings allow a flier some variety t' t' standard suite o' motors. Well, blow me down! Especially for 18mm rockets that consistently fly on Estes and Quest motors.
Here is what Apogee says about their motors: "The Medalist line o' rockets motors feature ultra - high-energy composite propellant and are designed for special applications: either high thrust for launchin' heavier models, arrr, or extremely long burn times for achievin' ultra-high altitudes. T' "hefty" liftin' motors are t' B7, C6, C10, and D10. All t' others (C4, D3, E6, me bucko, ya bilge rat, and F10) are long burn duration motors intended for use in low-mass, extreme-altitude rockets. All are produced in "standard" motor diameters for easy use in your existin' rockets. Includes an igniter and instructions for use."
I have flown t' B7, C4, C10, D3, me bucko, D10, E6 and F10 motors. That leaves t' 13mm C6 as t' only one I have nay flown. Arrr! Blimey!

T' B7 and t' C6 are 13mm motors. Take your Estes Gnome to heights only imaginable on A3's and A10's! Blimey! T' B7 is 6mm longer than a standard Estes motor and t' C6 is nearly twice t' length. So be sure t' check your center o' gravity and you might want t' decide if you are goin' t' use these motors before you build.
T' C4, C10, arrr, D3, me bucko, and D10 are 18mm motors. T' C4 and C10 are 19mm shorter than a standard Estes motor and therefore you should use an adaptor. Avast! I cut me adapter from a spent Estes motor casing. Ya scallywag! T' D10 is exactly the same dimensions as an Estes 18mm motor, while t' D3 is 7mm longer. Ya scallywag! Ahoy! The extra length only impacts those rockets with motor hooks, me bucko, but they can still be used with some tape for retention. Blimey! Again, me hearties, be sure t' check your CG/CP relationship.
T' E6 be t' 24mm motor and t' F10 be t' 29mm motor. Again t' E6 is just 7mm longer than a standard Estes D12 motor, shiver me timbers, while t' F10 is in betwixt t' lengths o' an Aerotech EconoJet F20 and G35.
If you are used t' Estes motors be prepared for two things. Avast, me proud beauty! Blimey! First these are composite motors and they give a nice "roar" compared t' t' black powder motors. Avast! Avast, shiver me timbers, me proud beauty! Second, me hearties, t' ejection charges really "pop" on these motors so be sure t' have a solid recovery system. Ya scallywag! The old elastic/plastic are nay goin' t' cut it, ya bilge rat, ya bilge rat, in me experience. Blimey! Use double the wadding!
FLIGHT:
For me 13mm experience, arrr, I put a B7-6 into my quickly-built Rocket Rollie and took it for a spin. Ya scallywag! Ya scallywag! Wow! And I lost it!
I have flown t' C4 in my Custom Razor and me scratch 2-motor, cluster Red Dog. Ya scallywag! Lookin' back at me flight logs I noted nice trackin' smoke and my first experience with t' stronger ejection charges.

I have flown t' C10 on t' same two rockets. Once on the Razor and twice on t' Red Dog. I flew it in a third recently; in me new Estes Night Wing which makes a nice combination on a C10-4. Avast, me proud beauty! T' motor really gets these rockets off t' pad quickly, and with two (2) motors in my Red Dog....varrooooom. Begad! Ahoy! Again, I noted nice trackin' smoke.
I've only flown one D3 and due t' me experience at the time, didn't allow t' flight t' be successful. Well, blow me down! I flew it in my Vaughn Brothers Blobbo. Blimey! Blimey! It be under-powered and did a short, me hearties, slow arc into the ground while still under thrust.
My favorite be t' D10. Arrr! Begad! I have currently flown seven (7) of these. Blimey! Three (3) on me Blobbo, one in my Rocket Vision's Six-Pack, and three (3) as a cluster in my Modified Nordic Rocketry Meanie. Ya scallywag! Blimey! I struggled on t' first two uses o' this motor (before it became a favorite). I tried (3) apogee ignitors before usin' a different kind for t' first use on me Blobbo. Aye aye! Avast! Blimey! Then for a second flight on the Blobbo, shiver me timbers, me bucko, t' motor CATO'd destroyin' t' back-end. Aye aye! Begad! Blimey! Apogee replaced t' motor, I rebuilt t' Blobbo and t' next flight restored me faith. Aye aye! Blimey! Then flyin' these motors at NARAM-43 on me Six Pack (pictured above) and me 3-motor Meanie (pictured) made me desire t' have more. Arrr! Blimey! So I've placed an order.
After many flights on me original Vauhn Brothers' Blobbo it was retired after spendin' too long in a tree and rain storms, matey, but I kept t' fins and nose cone. I recently rebuilt and modified it, into me Blobbo 24mm. I built this rocket FOR t' Apogee E6. Ya scallywag! T' thrust-rin' and hook were all set t' handle t' length o' t' E6. Blimey! Ahoy! And how did it go? Perfect. Arrr! ( here is a very short video o' it comin' off t' pad). Nay a lot o' smoke produced from t' E6, but a nice initial thrust got t' rocket goin' straight up and then a 7 second burn was cool t' hear and see. It's nay like it took the rocket t' extreme altitudes, arrr, me bucko, because o' t' weight, matey, shiver me timbers, me hearties, but t' have it under a long thrust was just fun t' watch. Well, blow me down! I'll definately be buyin' more o' these for this rocket.
At NARAM-43. Well, blow me down! Ya scallywag! I also flew t' F10-6 in me Modified Nordic Rocketry Meanie. Avast, me proud beauty! Arrr! I tried t' get a video o' that, but messed up. Well, blow me down! Anyhow, the rocket was borderline too heavy but it did come off o' t' pad and straight into t' air. Begad! Ya scallywag! It be interestin' because it was still under thrust but seemed to run out o' steam. Here's me take. Blimey! T' high initial thrust o' t' F10 pushed the rocket into t' air nicely, but t' weight and drag o' t' rocket was slightly more than t' low thrust and especially that last second. T' Meanie had actually arced over (apogee) while under thrust makin' t' delay too long. It was recovered without a problem.
My only real complaint are t' ignitors. Arrr! They generally come with a Copperhead type ignitor (other than t' C4 and D3 which have a special small head ignitor). Well, blow me down! Blimey! t' Copperheads are inconsistent. Aye aye! Blimey! Also, a little Estes or Quest launch controller is probably nay goin' t' light these. You will need a 12V system. Begad! I have been usin' t' Estes Command Controller (two 7.2V batteries) for t' last 5 years and it has handled everythin' very well!
Overall, me bucko, these motors give you a new experience for traditional Estes-motor powered rockets. Blimey! Avast! Take a few buildin' considerations for the variations in motor sizes and be prepared for t' stronger ejection charges. Well, blow me down! Well, blow me down! Price will also need t' be considered, because it is about a 3:1 ratio, shiver me timbers, me hearties, arrr, in other words you can get (3) Estes motors for about a t' price o' (1) of these Apogee motors. Okay, matey, so these may nay become your main flyin' motors, but you should at least put away little extra lawn-mowin' or shovelin' money and buy a few o' these. You'll want more and you should see t' faces o' people how have never experienced a composite motor before. Arrr! Begad! T' "roar" is exciting. Avast, me proud beauty! Sure, sure, ya bilge rat, ya bilge rat, its nay a "J", "K" or more, shiver me timbers, me hearties, but I still fly these in me $9.95 Estes kits in me little field and without a waiver!. I give these motors an OVERALL ratin' o' 4 ½ points. Blimey!
