I think the peak thrust Jim is referring to is within the first 1/2-1 second after lightoff. This is to insure that the fins become effective after passing the launch rail.

I only use Aeropack for all my motor retention and adapters. I have used my 98/75 adapter about 10 times now and have let others use it as well. Nothing beats Aeropach for quality and ease of...

It wasn't marked on the grain. It was marked on the pink static bagging. It was just my mistake and forgot to remove the WC marking.

When I have one or two pieces of extra propellant left over I seal them in bagging. I write on them what they are and they are placed in an airtight container. When I make another batch I remove them...

I am looking for an AMW 98/17500 case only.

I am looking for an AMW 98/17500 case and nozzle.

Did you remove all the grains from the liner and inventory it. I place all the orings, fiber washers, etc including the smoke grain between all the grains so that if the packaging gets opened nothing...

I have for sale a Fisher 98mm/11000 (34.25" long) motor case that he made for me. I was going to have Fisher make my 98mm casings (3.50" ID) for me but I decided to go with the standard 3.550" ID...

Some yes some no. Go to the following link and it explains what you need and don't need for all the 38/390 to the 98/11000 motors.

I don't where you read that but it is true. Gorilla aluminum cases are identical to AMW but the forward closures and/or nozzles may be slightly different. I have that information on my website too. ...

The 'pos' works fine and I get a GPS position. When I push the 'list' button all I get is "> 1: No Data" . Do you use the stock antenna or another one? I've seen people using the Arrow 5 element...

Thanks Will. Now how do you get the APRS GPS coordinates off the D72? I got it working but I don't know what buttons to push for the Beeline GPS coordinates.

Kevin,

What is the step-by-step procedure for the VX-8GR? Maybe I can make one for the D72 with your intructions for the VX-8GR.

Does anyone know the steps on how to setup the APRS on the Kenwood D72 for using with the 70cm Big Red Bee GPS?

Ditto on the Maha Powerex true 9.6v batteries. Outstanding batteries.

I thought that comment was odd myself.I don't think TMT wouldn't certify because he thought the case was inferior but rather than some dimensional specs that were too different to certify. Paul...

I didn't say that AMW reloads are more powerful. Neither did I say that LOKI case is so inferior. You are the one that said both of those. All I said was that drawn tubing was superior to extruded...

LOKI did make tubes for Paul for a short time but Paul supplied the drawn aluminum tubing. Gorilla uses the same drawn aluminum tubing and specs as AMW. Gorilla was supplied the specs and aluminum...

Woke up this morning and went outside. Had to go back inside and get my jacket because it was cold (65 degrees).

Is it AMW?

Sold last night.

Not plugged. Will not split up. All or none.

I have a Big Red Bee GPS unit. As Will Marchant stated he was downloading APRS info from the BRB unit. The Kenwood 72 also has a built in GPS unit.

My question to Will Marchant (or anyone else)...

Wiley,

Thanks for the compliments on my sparkies. The K980BL sparkies that you were referring to on the NEFAR website (maybe mine too) were demo motors before certification. I have several...

Are there any links out there on how to do staging?
