I’ll be working on the Proton again this Sat. More glassing and hopefully more work on the motor mount assemblies. We have a grill and were thinking of having burgers or dogs for lunch.Let me know if you are coming…   Read more»

Got to work on the motor/fin assembly today .. came out great. Just need to cut in the MMT’s … a central 98mm and 3 – 75mm.

Before you worry about commercial motor costs, why not have Joe Hinton talk to Dr. J at Cesaroni and see if we can get some comp’d motors or at least motors at cost? Cesaroni has been quite free in the…   Read more»

Perhaps another option would be to stick with the EX motors for the 75mm mounts, but go commercial for the 54mm mounts. You could go with 6 grain Cesaroni cases and use either the 6 grain K260 “Classic Longburn” reload…   Read more»

This sure is stacking up to be one hell of a MHM.Just for the record. I have a new camera this year. Betterpictures and better video.1080 and lower HD and slow motion.Continuious and burst still shootingBetter zoom.But remember it is…   Read more»

After meeting with James Russell today we have agreed on motor options for the 1st Proton M flight.The booster will have a central 98mm mount and 3 – 75mm mounts. The outboards with have 54mm mounts. The sustainer will have…   Read more»

By the way, I have both Loki and AMW 1750 cases…. I’m not sure if the Loki is 1750, but it is close and I have a K250 moonburner load I’d donate.Thanks Warren, I think I am going to go…   Read more»

Oh wait… 1/2 bates grain fast burn and 1/2 moon or end burners for the outboards….. I’ve got one of each I’d donate to the project.

Rough Estimate without quotes -Case – $30Closure – $10Nozzle -$30Snap Rings/Nozzle Washer/Thrust Ring – $15$85 materials.If you want it turned to 75mm instead of true 3.00″ it would be ~$1 per inch. I much prefer not to turn down casings.Edward

54mm is the one size that is more economical to buy the casings. You will get much more interchangeability with drawn 2.125 x .095 wall tubing than you will turning a bunch of pipe for 54mm.That is one reason I…   Read more»

Edward, Fort Collins is much more accessible from Wellington than Longmont for frequent trips. Is there something I can do to help or at least come and observe when you make motors?

Strongly suggest moonburners or endburners for the outboards.

Since this will be a research flight with the O-motor – are you looking at doing research motors for everything else?If you want to do the 75mm 2/3 grain motors I could volunteer the machining if the project bought the…   Read more»

I need some more motor mount tubes, 54mm and 76mm .. anyone got any they want to sell/donate? I’d like to get them for this weekend if possible.Thanks! SteveSteveI checked all the tubes on the wall tonight. Well….if you need…   Read more»
