MAAV Quick Prop Mount |
MAAV Quick Mount for Paramotor Propellers
The Design Philosophy
-The MAAV design was guided by fundamental aviation design criterias.
Therefor the MAAV uses an inherently safe captive design. i.e all parts are mechanically constrained by the design itself.
-The MAAV mount is staticly balanced by design. And has been validated in tests up to 4500 rpm without any problems. (Max propeller rpm from a Moster 185 @8600rpm /1:2.68 is ~3200rpm)
-The total weight of the 20mm spacer version is less than 395g
The Latching Mechanism with Unique Lock
-The latching machanism is 5-axis machined from aviation grade 7075 billet aluminium.
-The uniqe latching mechanism allows for great levrage when tightening the first step by hand, and then applies a great additional force once latched down, all with with very little effort from the operator
-The most important design feature that sets the MAAV aside from other quick mount systems is the anti rotation lock. When clamped, a steel pin locks the rotation of the latching mechanism to the rotationally fixed Pin plate. In short, this eliminates the possibility of the main bolt to unscrew itself if the lever arm is clamped down, even if it is not tightened hard.
This safety feature is just a additional safety in the event the latching mechanism is not tightened properly. **the mount does not rely on this feature to function if its tightened correctly when installing the prop**
The Main Bolt
The main bolt is of such importance that it can not be under dimensioned. The bolt should not only handle high momentary loads, but also extended use which could cause fatigue in a smaller bolt.
-The MAAV uses a M12 (grade 12.9) bolt with form rolled threads. The main bolt is threaded in to the mating threads in the base wich is made from 7075 aluminium and lined with a stainless steel Helicoil thread insert for maximum strength and longevity.
This bolt makes the MAAV a couple of grams heavier. But for the added weight of way less than a car key, the safety and longevity is greatly increased.
The Base
-The base is machined from aviation grade 7075 billet aluminium.
-The center thread is lined with a stainless steel Helicoil thread insert for extra strength and wear resistance.
-The guiding pins are made from centerless ground stainless steel pins. The pins are dimpled and pressed in from the back side. Making it practicly impossible for them to come lose.
The Plastic Composite Hub
This component is machined form as solid piece of industrial glasfiber reinforced Nylon PA6.
Its main function is to constrain the latching mechanism and make it impossible for any part to come loose.
This part is also critical for the balancing of the whole assembly.

Maav Mount Maintenance I (pdf)
The MAAV mount fits on Vittorazi Moster 185 engines with 6x60mm bolt pattern and 25mm center tap and accommodates 2 and 3 blade E-props propellers ONLY!
- For other propellers like Helix or Falcon a spacer is needed. Spacers sold separately.
- One complete MAAV unit with base (10mm base) and latch assembly
- The mount is delivered with mounting hardware. (6pcs M6 countersunk screws)
- Installation instructions and maintenace instructions comes with the mount.
