Free-Flow Adjustable Venturi Mount for Aircraft Engine


THIS DESIGN OFFERS A FREE-FLOW VENTURI EFFECT. THE PROP
AIRFLOW DEFLECTION PROBLEM CAUSED BY CONVENTIONAL
PLYWOOD BOX CONSTRUCTION CREATES CAVITATION, AND THE
ADDED LOAD REDUCES ENGINE PERFORMANCE BY AS MUCH AS
20%.

This fully adjustable motor mount gives the versatility of linear movement
by eliminating firewall plywood box buildup. The larger mounts (for DA,
BME, or 80 through 240 cc engines) not only allow linear movement,
but also allow vertical adjustment.

How to Use: For down and side thrust in the field, trim adjustments are
made simply by loosening allen head screws (1/4-20) from the back
side of the universal mounting plate and inserting angular shims
provided by D&R Industries as an option. Spot glue the back support
yoke assembly. After center line adjustment, drill clearance holes for
1/2-inch diameter standoff supports. Whn proper clearance is obtained,
tighten 4 screws (8/32) located on the back support yoke.

  
  
  
  
  
  
  
  






Model Aircraft Motor Mount

This unique design saves the builder from
having to build a plywood extension from
the fire wall to the critical prop-to-cowl fit.
The design gives you full linear adjustment
from the firewall for prop clearance, as well
as onsite full adjustment to side and down
thrust for trim changes.


4-Inch Gang Cutter
The significance of this specially-designed 4” cutter is that it gives
the user the capability of utilizing a standard brazed ½-inch tool
bit or an insertable tool. This means a different geometric variability
for ferrous and nonferrous metals. The most significant advantage
is the cost factor: $40.00 per insertable tool change, versus $12.00
for our cutter. The most effective feature of this tool is its versatility.


Sig Sauer Blue-printed Barrel
This is a match Sig Sauer blue-printed barrel. Its design gives the highest degree of accuracy
for the match shooter, in law enforcement as well as military use. Our experience with gun
sights and complete prototyping of firearms demonstrates our diversity.
