I got a fliskits tres, and modified it to have a 24mm mount between the 3 18mm mounts.
rocksim says 1700 on 3 c6's and an E9, I don't want to even think about F21W's

pics coming soon

sounds cool, its kinda hard to picture though
how did you fit that mount between the other motor tubes, theres no room on my tres.
a pic would make this thread much cooler :D
 
oh man, i would *donate* (in the name of rocketry) an F21-8w just to see that happen. how about, c6's all around and then an airstart of the F21!!! that would be INSANITY!!!!

That's.... Interesting. Are you planning a boattail around the 24mm MMT?

Do you think you'll need any nose ballast to offset the add'l motor?
 
Extra mount looks ugly? I think so

soo.............

pic

much better

I added nose weight, rocksim puts it at 1.7 calibers loaded
 
looks intersting, clean up all those stringy things (whatever those are) and finish it nicely and it will be a very unique rocket
 
I never cease to be amazed at the creativity out there and I am thrilled when it is applied to one of our kits :)

Between Gordon's Tres with the tail cone, John (i believe) and his mid-body motor mount and Carl's upscale, this one ranks right up there! :)

A while back someone had asked the question about if it were possible to get a 4th motor in that position. The general feeling was "no", and you have proven us all wrong :D

keep us posted with more pix!

That's a different slant to the kit.

My modification was to make a two stage Tres after a rocket
landed and damaged the original kit badly.

Rocksim says 2368ft :D

Its being finished right now, I'll put more pictures of the painted rocket.

the "stringy things" are bits of hot glue, that picture was taken about 20 seconds after gluing those toothpics
 
you used hot glue?
what about the fins, is that hot glue too?? (it looks like the "stringy things" come from the fins too, maybe its just me)
 
hey, let me know if you're up for a tres f-21 shot...i've got the motor.
 
I used hotglue on the fins, but then reinforced it with a ton of wood glue. The toothpics are attatched to the fins, which would explain why they are coming from there.

I won't do an F (for now:) ), but may do an Aerotech E 30, which should be in the vicinity of 2000
 
i dont think you should launch it to 2000 feet, theres a much bigger chance of losing it then not losing it at the amesbury field.
if you want to use big 24 mm motors, why not just lauch it with one engine and forget about the 3 18mm cluster for now.
 
just a thought, max altitude tomorrow will most likely be 3 cs and a d (1350), but I may do the E9 instead if I feel particularly crazy tomorrow. E 30s and F21s, if at all, will go next year, as I can't make it to CMASS' last launch:(

At least toothpicks are cheap. You might want to trace a fin just in case though.:rolleyes:
 
im wondering if anybody else except for cato uses hot glue for fins

It works, as long as you reinforce later with wood glue or epoxy
 
Okay, It flew twice at Cmass today. First was on 3 B 6-4s, and nothing in the center. 2 of 3 ignited, but still went reasonably straight, to about 300 feet. second was on 3 C 6-7s and a D 12-7 in the center. All the Cs ignited, but the D didn't, and due to the extra weight not producing any thrust, it was a bit slow off the pad, and so it tilted at about 80 degrees to the ground, and due to the long delay, the ejection went off at about 5 feet. lost a fin and the addition to it. It probably won't get another chance to fly untill next spring:( , but I am redesigning, with fins on the 24mm mount.
