Propelled Engineering-NEW Rotary FWF company!
 

I was just reading the latest issue of Contact! Magazine, and there is an article on the new company called Propelled Engineering. They displayed at Sun N Fun this year, and are ramping up for production of a complete FWF rotary kit!

And the first thing they do is put the fuel pumps on the firewall...Worse place you can put them from a vapour lock perspective!

FWF Rotary package
 

I believe if these folks do it right they will be wildly successful and make tons of money.

Eggenfellner is selling dozens of engine packages a year.

I could never figure out why Tracy Crook didn't produce a FWF package, since he sells about 99% of the stuff needed for a package, and he seems to produce quality components.

Best of luck to Art and Cheryl!

Could be pretty good for many people but do they have it all flying? If so, how many hours? Price is pretty similar to Eggenfellner and quite a bit higher than the clones.

Not sure about the SFC comments. Yeah wrong place for the pumps IMO.

Anyway, good news for Wankelers and they are using Tracy's drive and ECU.

Worth watching for more info.
:)

Aren't low wing FI fuel pumps normally placed inside of or close to the wing tanks?

Without seeing an RV example of this system fully mounted, it is hard to formulate an opinion. I saw nothing there about the motor mount, cooling system, exhaust system, ignition, and little about the intake- it looks like they cut off and altered a Mazda intake manifold?

IMHO, it looks awfully expensive for what is delivered- a lot of unnecessary custom parts. $400 for remote oil filter/lines, 500 for steam separator, 1350 for machined motor mounting lugs??? No thanks.

Didn't I hear that Eggenfellner may have sold out for this year as of the end of Sun N Fun??? :cool: Mine is booked for 2009 already, so their order book goes out a ways...

I feel the same way, Mickey, about Tracy. He could deliver a nice FWF package at a really decent price, considering what he's already selling.

This package seems expensive, but I wish them well since this is the ONLY FWF rotary package becoming available.

As far as I know, they are NOT flying this yet, Ross.

Hydraulically speaking yes they are. The standard AFP boost pump package is placed on the floor on the cool side of the firewall. Not the absolute ideal situation as you really want absolutely no restrictions between the tank and the inlet to the pump. In practicality however you will at least have a filter between the tank and pump.

MY FI pumps are indeed in the wing roots, almost ideal from a (non) VL point of view but you have to take the wingroot fairings off to get to them and you should leave a small reserve in each tank should a pump quit.

I don't have a mechanical fuel pump...The system works very well and this is the second airplane I built this way.

One should make sure the pumps are independantly wired of course.

Huhh??

Don't quite follow your thought process there - are you saying you should always switch tanks leaving a little reserve behind (don't run it bone dry), in case the full(er) tank pump should decide to quit, which would then leave you with the other functioning pump and a short reserve for an emergency landing? That would make good sense in ANY case, not just with FI pumps.

Be careful, take deep breaths
 

Take a deep breath this is not the second coming.

I HIGHLY recommend that interested people wait, in my opinion, wait until they have many customer built RV's with their FWF and get some data. It is that or personally flight test their prototype product, before plunking down $27,995.00 + crating and shipping which are extra. Plus you need to buy a PROP.......(what kind of engine, used rebuilt and to what standards?)

Frankly it seems that going with RWS you can save at least $7,000-$10,000 over what they are offering? My point is because they have a web site don't be so quick to put your money and life on the line.

Not to be contrary, but how are they going to have "many customer built RV's with their FWF" to compile data if everyone waits?

You advise people not to go an alternative engine route until the fleet has many thousands of hours on hundreds of customer installs, but just how is a company going to get those hours? Do we expect them to give away free engines to the first 100 customers? I mean, come on George, someone had stick their neck out there and install the first Lycoming, right?

P.S. I have a Lycoming on the front of my RV-10, but I don't understand why we're so quick to poo-poo the guys who want to experiment.
