Rather than reinvent the wheel (rocket), how about getting Bill at BMS to make more Alway Saturn Vs?

Bill is probably easier to nag thanEstes.

>It does matter.

Allow me to me rephrase, it doesn't matter if you want to fly single engine or more, larger or smaller rocket, scratch, kit or otherwise, all you need to do is determine the scale and the correct thrust to weight ratio regardless, and you can make any airframe successful to the degree you want it to be.

>Too many people try to do things the model wasn't designed for, and then blame the model for the issue.

Agree 100%.

Jerry is also correct, many people over build especially for low power.

Sandman what would be the best way to do that? I have been emailing hem off and on for the past year and all I get is not in production.

Out of the loop.

It's not risky at all if you fly in minimal wind.

Wait...I take that back, there's a greater chance of CATO with a D12-3 than a 1/2A6-2. Boom! Otherwise, as long as the motor works, the model is solid. Of course, I am referring to the old Centuri version which had clear fins that allowed it fly rock solid straight up.

On the clear fin note, IIRC, the K36 had clear two piece slip-on fins. The Centuri fins used a single sheet with a slot giving the fin a slight roll producing airfoil. The roll rate was slow, but it probably gave some added stability as long as you remembered to keep the airfoil turned the same way on all four fins.

I have found that the slightly 'oversized' fins on the first Estes re-design of the K-36 (think it is the 2001 kit number or something like that) provide PLENTY of stability without any FUGLY clear-plastic fins. At least they do on mine with up through 80 n-sec 29mm full-F power.

It did. It had a side burning SU motor with slow burning propellant and a delay set to the pre-calculated apogee.

Use a slide ring on your parachutes.

The 2001 kit's balsa fins are considerably larger than the Centuri and K-36 fins. The Centuri fins are oversized a bit as well. K-36 fins were closest to scale, IIRC.

I've never had much luck with slide rings on little plastic Estes chutes, but I was young and didn't spend much time fiddling with them. Worked pretty decent on nylon chutes where I didn't need them.
