I doubt it. What about a 4" MD on a Pro98-6xl 75% or greater N motor? I would guess that a 3" would be the best for an M, but the extra impulse of the N should more than make up for the additional dra...

A mongoose 98 on an M3400? That should be awesome - my current design will go quite high (5" fairly light, simming to ~18k on the 3400), but a MD 4 inch should be spectacular. When do you plan to fly ...

Yes it was - it drifted much farther and in a different direction than expected. Glad to have it back - thanks very much to whomever returned it.

I have the handheld - you're welcome to borrow it if you just get the transmitter (~$150 for a brand new DC-30, less for a DC-20 or a used unit).

Excellent 🙂 With the 98-4g and a couple of spacers, I'll have a ton of choice when it comes to 98mm loads for my L3 rocket (which I'm finishing up the design on right now). It should be a good case to...

Hmm... I may take one of those M3400s - will it be offered with a similar deal when it shows up later in the month?

I don't know about that one, but I have one of the 100g models of this one, and it is great. Up to 100g, in 0.01g increments. Perfect for charges, epoxy, and thermite mixing.

I think I figured out why my drogue descent rate was 180fps - I was looking over the data, and the charges weren't nearly as energetic as normal. My apogee separation was somewhat delayed, and only re...

Its always 1 grain, but I believe it is stackable.

I agree about the "drop it as fast as possible" comment - my Amraam had a descent rate of 180fps under drogue (somewhat accidentally though - I'm not sure what happened, but normally it is somewhere a...

I flew my DC-30 to 17k, and I was back at the pads in ~45min (I landed 3/4 mile or so from the pads, and in an area where there really wasn't any road that was any closer). Walked almost straight to i...

Great job - congrats on the perfect L3 😀

Plywood at Mach? Splinters. Use G10 on everything with light (& different) layers of composite material. Did you see JW's record altitude rocket? See the Mach burn on the fins? Plywood will not ta...

Agreed. I think it's fairly safe to say larger sparkies are pretty much out. Have fun finding LPR too... 😯
