Aerotech Motor RMS G104T ??s on Cases

[AstroMFPII]

Buyers like me should really read the details when purchasing motors. I recently purchased 4 G104T-M Aerotech RMS motors from Wildman and did not notice 100 Case only, not Wildman's fault Newb fault. With that being said, I have an Aerotech 40-120 case complete and a Aerotech 180 Complete is there anyway to get the G104T to work in these cases or should I just bite the bullet and buy the Aerotech 100 Case. The adapters for Aerotech are around 60 bucks, since I already have aft and forward enclosures should I just get a barebones 100 case. Opinions needed and wanted

Thanks
Mike

I'd buy the case.

40-120 is no good. You could purchase either the 100 or ( I think ) the 29mm RAS

The RAS only has spacers between the normal sizes. If you look at the designations, most of the 29mm cases differ by 60 Ns. So you can use spacers to go from a 29/120 to a 29/60, or a 29/240 to a 29/120. The 29/100 doesn't fit that standard grain size, so you can't use the RAS to adapt to it. @AeroTech could probably make a spacer to adapt to the 29/100, like CTI does for some of their oddball case sizes, but I don't know if it would make sense for them to do so.

Best bet is to just grab the case

I feel the same way about casing designations as I do about tire & wheel sizes.

Yeah I have 5 of the G104T-M motors. Preparing for Level 1 flight that was why I purchased the 180 case. Lot more choices for H motors in 180 Case.
But I do a lot of 29mm Sugar based motors so extra HP cases are good to have!
Thanks everyone

Note... just to be sure you are aware. The "Hobbyline 29/40-120" case has different ends (threads, diameters, etc) than the 29mm HP cases.

The 29HP cases use the same ends, and come in 60, 100, 120, 180, 240, and 360 sizes.

thanks I bought the 180 with the hp ends

In that case.... just buy the 100 case. You CAN'T use the 29mm RAS (reload adapter system) to get to 100... if you have the 180, (1) spacer will let you use 29/120 reloads, and (2) spacers will let you use 29/60 reloads.

Your 29/100 will need the 29/100 case. (If you get it with ends, you can load up more motors... )

The G104 is a great load

I brought this item up on the Aerotech open thread a while back... all it would take is a one inch spacer to put a 29/100 reload into the RMS 29/120 casing (a 1 inch spacer could adapt a 29/60 reload into the 29/100 case). They apparently dont move enouh 29/100 or 29/60 loads to justify production...

The G104 is a fun motor, good for those heavy 29mm birds on small fields, when an F52 isn't quite enough, but a 120 N-S G would send it too high.

Being able to use this reload was actually my original motivation for getting my L1

According the Amraam 2 Data Sheet, the Amraam 2 does 1231 feet on a G104.

I checked my one drive and my laptop and I don't have my Rocksim file for it so I can't check my sims. My Personal PC at home is off so I can't check that till I get back to PA whenever that is.
