quest micro maxx vs estes minis

[woodsman]

simple question.... are the quest micro maxx motors 14mm like the estes minis?

Well, yeah, they're both rocket motors....

Other than that, not much.

Physical size: The Estes "mini" motors are 13 mm in diameter and 1.75 inches long.
The MMX motors are half that diameter, and about 1 inch long.

Motor power: The Estes "minis" go down to 1/4A impulse classes, and are available (or, they have been in the past) with a variety of thrust profiles.
The MMX motors go up to 1/8A impulse class; beyond that you have to start clustering.

General utility: The Estes motors are available with a wide range of time delays.
The MMX motors have one option.

They cost about the same per motor (roughly). They both burn blackpowder. They both are fun. That's about all I can think of--

To more directly answer our very simple question:

NO Quest Micro Maxx motors are not like Estes 13mm mini motors.

Micro Maxx motors are 6mm in dia. x 1.0" long (1/8A.5-1)
Estes Mini motors are 13mm in dia. x 1.75" long. (1/4A3-2T to A10-3T)

Hope this helps.

Micromaxx motors are great for gliders--they are small, light, and have short delays.

The Estes 1/2A3-2T is the only motor that is really good for gliders--the other Estes motors have delays that are too long. The A10 has a bad thrust curve.

MicroMaxx is another step down from Estes Mini motors.

Micro rocketry - building and launching rockets on Quest MicroMaxx motors mimics nearly all of the same features as low-power rocketry, but in many ways it is a different and unique discipline.

Estes Mini T motors, aka Mini Brute motors or Series IV motors, developed out of the earlier Estes Series III motors, aka "shorties." They have essentially the same interior case dimensions as the 1960s-era Estes Series III motors, but have a smaller outer diameter that was achieved by reducing the wall thickness of the casing.

Quest MicroMaxx motors are 6mm (roughly 1/4") in diameter by 26mm (1") long.
Estes Mini motors are 13mm (1/2") in diameter by 45mm (1.75") long.

Estes minis range in impulse from 1/4A to A.
Quest MicroMaxx II motors are all designated as 1/8A.

Some years ago Apogee Components had a line of Medalist motors that were approximately 11mm in diameter. Apogee called them Micro motors. They were produced in more than one length, and ranged in impulse from 1/2A all the way to B. They were primarily intended for contest use. They ceased production in 2001.

The Estes Mini motors are small, but as you can see from the attached photos, the Quest MicroMaxx motors are REALLY small.
