5-V belt drive system plans for propeller driven craft from Air Trikes

Description

You are bidding for
a set of plans for a belt redrive. You can make your own redrive using these plans.
This is NOT a complete redrive or set of parts but PLANS.
5-V redrive system is designed especially for snowmobile engine conversion. Can be used for Experimental or Ultralight aircraft, hovercraft, airboat etc. This classical system consists of two 6061 T6 aluminum pulleys for 5 V-belts, eccentric shaft with heavy-duty closed ball bearings, motormount plate and all machined parts, rubber elements and hardware necessary for engine installation. It can be made at most of machine shops. I used this redrive with licensed Rotax 640 from 1998 like a powerplant for my "Frigate" trike. It has been installed on Rotax 503 for my "Eagle" trike. This system has a lot of advantages comparatively with other redrives:
a) Very reliable. Will be working with 4 or even 3 belts. You don't have to be so worried about your belt condition like with your single belt drive.
b) Very light and less expensive comparatively with gearboxes.
c) You can use not only provision-type Rotax but also non-provision. You don't need to convert the engine itself.
d) Spare belts are easy available and not expensive (Car Quest XL serie for example).
e) Reduction ratio can be easy and smoothly changed by changing the pulley diameter.
f) The engine can be installed head-up or down.
g) This system can be easy adjusted by changing some installation dimensions to almost any project.
h) Quick (a couple of minutes) and easy adjustable belt tension.
i) It is a whole conversion unit included a motormount plate and 4 metal-rubber silentblocks. You need nothing but muffler and prop for your engine installation on a trike or UL plane.
This system is available now as a set of drafts (13 .dwg files plus description .doc file).  You can modify it for your own project the way you wish. It will be sent to you by Email after your payment. Don't forget to provide me your Email. Contact me if you want a ready gearbox, belt drive or propeller for your homebuilt.
