The heartbeat of the package is the Chevy 4.3L V6 engine. This engine has been modified for Horsepower and torque in the 3000-3800rpm range.  The Belted Air Power PSRU has the ratio of 1.43:1. That means that 3500rpm on the engine yields 2447rpm at the prop. That's right where it should be for cruise and the engine isn't overworked at all. 


 
Here is one fine example of an experimental tripacer built by Kirby Miller in Alaska.

If you decide that this project is for you, then contact David Blanton via email to obtain a set of the plans and the builders manual. Dave's email address is daveblanton@cox.net


Scott Hermance in the Denver area built this great airplane with the Ford 3.8L V6 and the Blanton redrive. Scott says he gets 110 mph cruise and about 40mph stall.

 




Landing Gear
The basic design is obviously Cub style. The new cabane is concealed above the bottom skin and the struts attach inside that bottom skin. The struts will have bungee covers just like the cubs but with no exposed cabane vee giving more ground clearance in this area.

The squared tail pieces were laid out using the stock pieces for dimension. The ribs were measured  and laid out in sets. The shear and break operation is straight forward but a light duty break won't break the chromoly sheetmetal. It does reqiure a heavier break.

The Chevy 4.3 V6 assembles just like any small block chevy. The engine came from the factory with roller lifters. I also installed roller rocker arms and double row timing chain and gears. The vin "Z" engine uses small block chevy timing cover, water pump and pulley. I also installed a Nipon Denso type 1 wire alternator that is internally regulated.

The pilot side was opened up for a door. The old sheetmetal and tubing was also removed. New tubing and sheetmetal installed, however the sheetmetal has to made to accomodate the new 3/4" tubing. You can't tell what condition the old tubing is in until you uncover it. It will most likely have to be replaced.
