Watched Apogee Components videos on YouTube.
OK it wasn't today, but on the 4th I went alone to the local park and flew an A, three B's, two C11's and a D12 in absolute wind free conditions. All but one stayed inside the fenced baseball field I was in. For all the MPR and HPR I enjoy, sometimes it's good to go out and remember what got me into it in the first place.

Who makes that trick fin jig you're using? The last fin jig I had was an Estes one that I got for X-mas back in the early 80's.
Thanks. I think I also saw one at the Apogee website. After seeing the price, I've decided I don't need it that bad. :wink:
Would foam weather strip serve a similar function? I have a hunch it would be too heavy / dense, but I imagine it to be available in different weights.
In any case, neat!
I now have plenty of lite ply to reinforce it with, and then some, so making pieces for tie down hard points is no longer an issue.Thanks, but yes, it is the wrong type of foam, the gooey type, so it cannot be sanded or cut with precision easily. It is much heavier.
This is the exact item I was seeing in my dreams, and it is available for virtually nothing. I like the black color dollar store foam board, as it is slightly less brittle that the white stuff, and that must be why it is a whole 35 cents more than a dollar per sheet. The paper peals off easier too.
I have enough stocked up that I use entire sheets for the silliest things. 6 of them taped together side by side make a nice surface for me to drive my vehicle onto so that I don't tear my clothing on the rocks in my driveway when I'm under there looking at stuff or working, and a few more taped together and taped to the sides of the vehicle mean that I don't have to come out into the hot and bright sun as I wriggle out from under it.
I'm considering building a garage out of it.
Spent some time sanding and polishing my 2.6" Super DX3. Not finished yet, trying to get it finished in time for MDRA next week. Here is a sneak preview. . .
Finished tweaking this design. 3in screamer.......

Fins cut [4] carbon uni-plate.
Tube rolled 11 layers carbon uni-prepreg.
Coupler rolled double wall thickness, carbon uni..blah..blah..bla.
Main in NC.
Test mule for telemetry.
External antenna on 3 in vent band.
We shall seeeeeeeee..........should be very interesting!!!!:dark:
Assembly begins tomorrow.
Anywhere I can follow this build?
:wink:
By the way this is the one I offered you to fly, but you said you didn't have anywhere to do it.
I may do some assembly type build, but the actual process of making all the parts is proprietary. What is being used is purchased by the pound, not the yard. Shipped frozen & must be kept frozen till use. Shelf life of 6 weeks.
400.00 just in carbon for 1 tube, 1 NC coupler & 4 fins. Fins glued on with another proprietary product then T-T with several layers carbon uni-prepreg, vacuum bagged. 750 degree high temp epoxy, & commercial ablatives.
If this flies as good as expected, it will be paired with a 4in booster. N to M.. carrying 2lb payloads [can-sats] to 90-100,000ft . Testing on smaller motor this fall at Airfest if finished by then. Working on imbedding telemetry antennas in airframe skin as it's carbon & they must be on exterior surface.
It takes too much time to photo document everything, as in a normal build thread. There is an unbelievable amount of research in this project. End result will be a spin stabilized sustainer for the Sparrow Hv-Arcus. Charlie's working on a Disc-gap-band chute for withstanding deployment & decent at mach speeds. Samples of tubing were sent out to a lab, for various tests...shear, compression, hoop, etc. Results are fantastic.
Here's a tease . So now it begins.............

Look carefully you can see shadow of motor in booster, only 9inches for recovery gear,between top of motor & I/S.
I'll hobble something together next week after some assembly. :wink:
