I flew 5 years with a Ross. I've disassembled and inspected 5 or so, =
just to help out other builders. Just want to offer a different =
viewpoint based on my findings:=20

First, all of the Ross's have large bearing that absorbs the prop thrust =
forces. I'm quite puzzled your statement that they don't. A very =
important part of the installation is to verify you have clearance to =
flywheel. I'm wondering if you are just confusing the pilot bearing =
damage issue with prop thrust? Ross redrive had one significant design =
oversight. This oversight caused around 80% of their field failures. =
Basically Ross picked a poor method of controlling input shaft =
clearance. Input shaft is the short shaft that goes between flywheel and =
gears. Low rpm torsionals caused that shaft to slam back and forth =
between flywheel and gears. This caused pilot bearing damage, fatigue =
failures on the drive plate. I changed the design by controlling thrust =
at the sun gear. All of those failures then disappear.=20

Second, Ross decision to restrict oil flow to redrive is very sound =
design. It limits flow because excess oil flow to redrive has =
significant effect on hp loss. A friend actually measured hp loss =
related to oil volume. I verified flow on my redrive gears & bearings, =
absolutely no issues. I do believe there were lube issues on some Ross =
applications, but definitely not true on mine. I don't understand why =
the difference.=20


There is a method of proving design changes that Tracy doesn't use often =
enough. Basically you measure how close the design is to failure. You =
don't rely on theory. For example, I verified oil flow just by placing =
aluminum slivers at key oil locations. Operate drive for a minute, =
disassemble. Slivers were washed away by oil flow. Likewise, you operate =
it, then quickly disassemble and measure temperature of various =
components. A friend slapped a plastic cover on his redrive, then =
watched the oil flow. These methods let you predict future failures. Too =
much design theory, not enough actual measurements. If you can force =
yourself to test your theories, you'll find tons of things you believe =
in, that just aren't significant.=20

I am in agreement that Tracy version of the Ross design is looking =
pretty good. When asked by builders which redrive to consider, his gets =
high marks. I don't have rose colored glasses. There have been a couple =
design oversights that resulted in failures. I like the solutions.=20

  Actually, George, The RWS drive was not just a redevelopment of the =
Ross drive. =20

  =20

  Tracy basically started from scratch and engineered a redrive that was =
designed to meet certain objectives while achieving a reasonable cost.   =
There is no other redrive I am familiar with that has anywhere near the =
number of flying hours that the RWS redrive has with none of the =
problems associated with the Ross.

  =20

  While there is a superficial similarly to the Ross (Prop on one end =
and rotary on the other, planetary gears in the middle {:>)) in =
appearance, the internals are considerably ahead of anything Ross had.  =
Pressure lubrication of the prop shaft for one thing, an integral thrust =
bearing for another, a removable propeller shaft for yet another, full =
oil pressure lubrication.  The Ross drive required a restrictor in the =
oil line to (can you believe this) reduce oil pressure - otherwise the =
thing leaked like crazy - even with the restrictor, the rear seal =
frequently was a leaky mess.  But, reducing the oil pressure was one =
reason the Ross had marginal lubrication in my opinion. Even then, the =
oil distribution inside the Ross was also not well designed.=20

  =20

  Don't get me wrong, I was glad to get a Ross - because it was the only =
thing around at the time.  Had old man, Lou Ross, lived longer he may =
have eventually fixed a lot of these issues, but unfortunately he did =
not and I won't go into the situation with his son, Chris.  But, we are =
fortunate that Tracy took on this challenge and did it right.  =20

  =20

  One thing I really appreciate about the RWS design is that it has a =
considerably different internal set up with easily replaceable parts - =
which was not the case with the Ross.  If you wanted to completely =
disassembly a Ross unit you most likely had to take it to a machine =
shop.

  =20

  Just wanted to make it clear that in my opinion the RWS should not be =
associated with the Ross unit which many have found shortcomings in.

    Steve,

    The Ross drive was redeveloped by Tracy Crook of Real World =
Solutions (RWS). Tracy now uses the 6 planet planetary (Ford Unit) and =
is about the best you will get  weight wise and value for money.

    =20

    There are other similar units - all have slightly different =
construction, however Tracy's is well proven. I will probably make my =
own, but only because of the tyranny of distance and associated costs.

    George (down under).

    =20

    Steve,

    I went with the RD-1B PSRU from RWS.
