The App Store approved my latest update yesterday. This adds a motor look-up option to the Altitude Prediction->Data Assistant screen. It also fixes a minor issue on the Static Pressure Port calculator screen.
Here’s a screen shot from the motor look-up screen.

My latest update was just approved for the App Store. This adds a body tube look-up feature to the Altitude Prediction calculator. There is a new button on the Data Assistant screen which will provide a list of tubes to pick from. After selecting a body tube, the tube’s diameter and area will be populated back to the Data Assistant screen. I’m working on a motor selection feature too. I hope to have that out soon.
Here’s a screen shot of the body tube selection screen.

Here’s video from two cameras of epic fail 3.
Against good judgement I made a third launch attempt (I was bored waiting for the phone company to fix my DSL). I had four Q2G2 igniters left, so I dipped the tips in pyrogen. I then attempted a wadding tape method, which I think worked fine, but probably taped them in too well.
I wired them up and used my Go Box. All igniters lit, but only three motors fired, and they didn’t all fire at once. It got hung on the pad while the first two burned. Then the other two igniters lit, with one motor firing, and the other pulling out too early. At this point it left the pad.
I really need to build the relay launcher. (And order more igniters and motors) The three motors that fired blew out of the back too, so my retention method needs work. I don’t have enough spacing to wrap tape around the motors and mounts. I have some tiny screws and nuts than might work. I would need to dremel off the head of a screw and glue between the four motor tubes, then screw a nut on after the motors are installed. I haven’t checked the fits yet, but is what I’m going to look at next.
