75 5120 motor

[David Schwantz]

What are you experiences with this motor hardware and its reloads? thanks.

 

[DAllen]

Pretty freaking good seeing how I got my L3 with a M1297. About as easy to assemble as most any other reloads. The only thing I had an issue once with was the grains were too tight to get into the liner. Not a big deal just peel off a little bit of the outer layer of paper on the grain and was good to go. Then again, I've had very similar experiences with smaller reloads as well.

I’ve used mine several times never an issue. Like dallen said, may have to peel off some glassine layers to get grains in liner. Never force them.

 

[David Schwantz]

what size rockets are you flying with it?

 

[Rocketjunkie]

With this size motor, you will get 4-6K feet in a 40 lb. (pad weight), 6" to 7.5" rocket. I fly mine a lot on the next smaller, 75/3840 and get 3-5k in rockets this size.

 

[timbucktoo]

what size rockets are you flying with it?

I’ve flown it in several ranging from 10-25 lbs dry weight.

 

[jd2cylman]

The best case in the 75mm line. Lots of reloads for the case. I have 3... cases

 

[David Schwantz]

The rocket I am looking at using it in is 12" dia and almost 120" tall. Don't have total weight yet, but I'll bet 40 dry.

 

[Jee3300R]

M2050 would be perfect for that rocket. Awesome motor!

 

[David Schwantz]

I looked at that one, will do a rrrock sim when I get home. She is aall built but without paint yet. can guess the weights of chute, cord and stuff. What have you flowwn with the 2050? I fly my 1/52 Saturn V on the K2050ST, and that is great.

new Tripoli ruling states you may not have more than 2 of the same case. i can help you with that

 

[Antares JS]

I got one with my COVID stimulus last year for my eventual Level 3 flight, since it's an expensive piece with a long lead time to get one. I'm hoping to get the documentation together and submit to TAPs this year.

Please explain. And can you point me to the reference? Thanks.

Apparently David forgot the (s) tag...

 

[David Schwantz]

Kidding, meant he could just give one away.

I could... But I'm kinda partial to 'em. Plus side is that I have one for each of my WM Extreme kits... Make flying all three in one weekend much easier.

 

[David Schwantz]

I like to have all mine preped at home also, get more flights in that way.

 

[dratliff]

Yeah, I have to agree it’s a great size. Did my L3 on a M1297 in a 4 inch Wildman kit, went to 13,570 feet and hit Mach 1.3

 

[David Schwantz]

Yup, got her this week along with the M2050X. I just wanna go mount it to my deck and light the damn thing

 

[JohnCoker]

Yeah, it has a nice range of Ls to baby Ms:

[David Schwantz]

Hi John, thanks. But I did not see the M2050X in the list or on the chart. Was it not certified when the data was compiled? Dave.

Good point. That motor entry was missing the case information. So I fixed that and updated the link.

Note that most things are produced live from motor data, a search link can be saved and re-used. For example, this will find all available motors for the case, now and in the future:

Thanks John.
