That looks great, What silver paint is it?
Rusto Metallic Silver. The pita was the taping. It'll look better with the yellow pinstripe.That looks great, What silver paint is it?
I doubt you’ll have problems with the decals. If the surface is bumpy, Micro-sol could help them conform.
I did that for the Exocet missile. Works great. For the nuclear symbols on the mini Executioner, I converted the white to black and will print on white background. The problem is that it's been months since I last did this and can't find the decal sheets so had to order more from Amazon. Doh! It's probably next to the D21-4T that I put in a safe place. There are some days when my age starts to show.A trick on home made label paper decals when the background is black, if the rocket background is black, and the foreground color is anything other than white, use a black sharpie along the cut edge, almost makes the edge disappear
I'm... gonna need an explanation for that expression.I like building em but after a while it's like eating pizza.
I can relate, my hobbies tend to come and go in cycles, I'm out of the rocket building phase (after binging on it last year), but I'm sure it will come back. In the meanwhile, I do enjoy @rklapp's updates thread.It's too much of a good thing. After two days in a row of pizza you look for something else to eat.
Without looking up the rocket, I'm not entirely sure which two are switched. I could guess, but I think it looks fine as it is.Semroc Orbital Transport. I messed up and switched the small and big fins. Do you think it makes a difference or should I rip them off and reglue?

Two 9v batteries in series. I measured it and it's at 16.5v and 13.7a when I press the button. I have a 1k resistor attached to the continuity light. Perhaps it's time to change the batteries?What power source are you using in your DIY controller again?
Today was worse than yesterday. Definitely winter here on the island.Nice video.
Gotta hand it to you, you got some cojones launching in this wind.
Karens...Enjoyed the program, as usual.
Did you get any grief from the Tennis players?
9V alkaline batteries absolutely cannot supply 13.7a. How did you measure that?Two 9v batteries in series. I measured it and it's at 16.5v and 13.7a when I press the button. I have a 1k resistor attached to the continuity light. Perhaps it's time to change the batteries?
Sorry, typo. 1.37amps. This was my first time with the C12-4. The continuity light kept going on/off, so decided to change controllers. Afterwards, I checked out the DIY controller and seems to work fine, so I'm thinking it was a finicky initiator.9V alkaline batteries absolutely cannot supply 13.7a. How did you measure that?
In any case, I'm not a fan of using 9V alkaline batteries for launch power. Almost anything else is better, e.g.:
- 6 x 1.5V batteries (a la PSII controller)
- 9V lithium rechargeables (insanely more powerful (current-wise) than alkalines). Just one of these should be more than enough for a day of launching, and it's easy enough to bring a spare or two with you just in case.
- LiPo pack. Best of all, if you're willing to deal with the vagaries of LiPo maintenance.
Any of the above should be able to handle a pretty wide variety of igniters reliably (except maybe copperheads, which I think would be happiest with the LiPo.)
Anyway, when I hear of a QuestJet refusing to fire that would be my first thought.
1.37 amps is not a lot for a launch controller. Strongly suggest switching to a different source, you won't be sorry.Sorry, typo. 1.37amps. This was my first time with the C12-4.

I have Lipo batteries. Someday I'll start using those.
