    Hmmmm sounds like a good point there!

    Aerotech RMS Delay Drilling

    Wait a sec.... I've had LOTS of people telling me exactly the opposite. in principle, it shouldn't make a difference I would think but I'm not entirely sure of anything these days. Come to think of it, with the AT DMS motors, it's not possible to NOT drill the ejection charge side of the delay.

    Of course if I actually read the package... I would've SEEN that it said B6-2, C6-3.

    So after all that... as we all know, the LJ-I has one recommended engine, the C6-3. I don't have an openrocket file for this one yet, but it seems to me a B6-2 OUGHT to be usable here for a great low altitude flight... anyone have an op on this?

    Yes I did. It seems a few of my concerns were relatively unfounded. I was in a bit of a reasonless rush to finish it which is why I now have an extra United States decal! But it seems that this decal is exactly the right size for a 1/54th k21 Gemini Titan clone that I'm going to be building...

    So as neil_w says you can't redux the motor hook 45 degrees from where it is... However... here is mine in a somewhat more finished form... I used Rustoleum 2x metallic aluminum paint (which I must say looks really good considering how un-smooth my primer layer was and all even after sanding...

    I feel like there is just enough daylight between the large nozzle and the motor tube to accommodate the flex of the hook... but I won't be building another one any time soon... I just purchased the parts from semroc to clone the k21 Gemini Titan that I built when I was 13 years old... (looks ok...

    If I were to do this kit again, I'd cut another notch in the aft centering ring for the motor hook and locate it in between the fins and nozzles 45 degrees from it's design location... leaving the nozzles in their proper orientation. It's not like you can hide the hook anyway.

    Nice job on the fins... mine won't look that good from that angle.... nor from any angle. I'd never done built up fins before and they are "ok" but not as nice a job as I should have been able to do. Hands are not quite as steady as they used to be it seems. In the "how on earth could you be...

    Well I did finally get it put together... I my just let the fins go as-is, not try to work too hard on it. The fact is that sometime it doesn't pay to do too good a job on a rocket that isn't for competition.... after 5-6 flights (heck with a cato even sooner!) it won't look quite so pristine...

    Estes Little Joe I Construction - I like the kit but I have to whine a bit...

    Thats some nice work there... I'm looking at page 6 of the instructions and step 3 on the "cartoon" instructions clearly shows the motor hook aligned with one of the slots in the drawing... with the faux nozzle holes between the fins. Step 1 of attaching the fins on page 8 makes special note...

    I know that there is only so much precision in paper and balsa... I just finished trimming away the excess. I probably don't need to state this but I used a brand-spanking-new blade to do the trimming... and when I had to saw at the paper, made sure that it was in the direction of the balsa...

    A collegue showed me an 18mm retainer that was amazingly slim... I think it was by Rocketarium. From the photo I think it would work beautifully... and there should still be plenty of space for the nozzles... you'd probably need to trim down the other parts a bit tho...

    It looks as Dry fit the fins.... not glued in. Close up... of the motor tube... I'm pretty sure a low-profile 18mm retainer would go here nicely. Where I sanded and where I filled... A

    Another alternative is an 18mm motor retainer... wish I thought of it sooner!

    Hello There... As the title implies, I've been building an Estes Little Joe I that I received as a holiday gift more than a year ago. I decided to start building it rather than finish my other rocketry projects since this was given as a gift along with a Super Big Bertha from the Mrs...

    Estes - (Astron) Cherokee D (K-47 or #1247) Gallery

    I think a good airfoil can be put on these fins... sharp on the trailing edge, rounded on the leading.... outside edge flat. May not be the best situation drag wise.... fortunately 1/8" balsa (I *assume* it's that) shapes easily. I'd probably go for it if I had that kit! That said, I did...
