Rotec R2800 Specifications

The Rotec R2800 is comprehensive and yet conservative by design, and has many desirable features and specifications:

� Total swept volume of 2800cc (172ci). 110HP @ 3700 RPM geared. Total engine diameter is 810mm (31.9").

� Dry Weight without any Acc's (no Starter Motor, Alternator or Carb) = 95 Kg

�Dry Weight with Acc's (Starter Motor + Alternator + Carb) = 102 Kg

� Propeller hub is driven via precision ground and matched taper. Propeller flange specs are standard and are the same as used for a Rotax 912 Series)

� Gearing is via a PSRU (Planetary Speed Reduction Unit) at a ratio of 3:2 Engine rpm:Prop rpm.

� Propeller / RPM Fixed 76" Diameter x 51"Pitch @ 2,400 RPM.

� Fully machined aluminium crankcase and heads. Steel 4140 billet crankshaft, nitride hardened and ground, running on two large anti-friction roller bearings, propeller support and end thrust controlled by single deep groove ball bearing (all standard practice). Steel 4140 master and link rods deeply I beam sectioned and plain bushed, all lubricated by mains oil pressure. Steel 4140 cylinders precision honed to a perfect finish and exact tolerance.

� The all important ignition system utilises two auto type spark plugs per cylinder independently fired by both a single self-energized magneto and Hall-effect 12 volt electronic ignition system, virtually eliminating total ignition failure when used in tandem. Timing is fixed at 25 degrees BTDC.

� Electric 12volt starter motor (rear mounted) including built-in solenoid for reliable engagement and cranking.

� 35amp alternator (small and also rear mounted) with built in voltage regulator.

� Single Bing 40mm constant depression carburetor offering excellent automatic altitude compensating mixture control for an incredibly smooth delivery of power. Fuel supplied by engine driven mechanical fuel pump, an electric fuel pump (not included) is recommended for back up. Both fuel pumps are configured in series.

� Dry sump lubrication via geared oil pressure and primary and secondary scavenge pumps. Auto style spin on oil filter are incorporated in the design.

� Conventional valve train (two per cylinder) incorporating classic dual row cam rings and roller tappets for smooth valve movement via pushrod and 1:1 rocker transmission (all oil pressure lubricated).

� All cams and bearing surfaces are nitride hardened and precision ground to exact tolerances.

� Minimum octane 97 RON or 100LL aviation or high octane mogas are recommended. Compression ratio of 8.5 : 1 is standard.

� Fuel consumption: Avgas 100LL or high octane mogas: 22 ltrs/hour @ 80% Power

� Recommended TBO of 1000 hours. All engines come with a 12 month 200 hour warranty from date of purchase, whichever comes first. NOTE ALL WARRANTY CLAIMS TO BE ASSESSED AND CONDUCTED BY Rotec ENGINEERING PTY LTD (SHIPPING NOT COVERED BY WARRANTY).

I got prices from them a few months ago, but is in my office at the moment....I know that it worked out marginally more than the 912S Rotax, but what a lovelly sound it makes...

This engine has softness appeal of note.....

[FAWGie]

I've found a copy of my e-mail from Rotec dated 3 July 2005....

The R2800 costs US$13500 at 6.2375 = SAR84 206

Prices go up by 10% on August 1st.....

[FAWGie]

The larger motor 150HP nine cylinder radial sells for US$18 750.....

Today FROM Jim Chernikeeff at rotek....

As you'll see the R2800 is a complete package and the items that come standard are usually "extras" with other engine suppliers - this in effect makes the R2800 the best value for each dollar spent. The current price for the R2800 is $13750USD Ex Factory Payment of a 10% deposit ($1,375USD) secures an engine at a fixed and firm price with delivery to your timeline within a period of 12 months from the date of order.

Nice..

As explained on this page we can make arrangements to get quotes on your behalf to deliver the engine to you for the freighting process. The entire process is very straight forward and Rotec assists in the entire sequence.
( * Note: If you don't wish to get involved in the delivery process we are currently offering Air Freight to an International Airport closed to you for $1100USD - the engine will be cleared through Customs ready for you to pick up. This price does not include any duties or taxes that may be levied by the authorities in your Country).

As you'll see we provide a comprehensive service which includes the ability to design and build a mounting frame for you or design one for you (at no cost to you) and you can build it yourself.

Think Agent's mate (met him at EAA) is buildinga Gyro with the Rotek. Maybe we go lookeee seee what all the fuss is about.....

You must have sent off the same enquiry. I just looked at my mail too & got the same one. Jeff knows this is a hot one.

Hi Andre,

I gather the plane you are looking at is a Bushbaby and being near enough to a Kitfox it would make a great and proven combination with a R2800. So much so that Rotec is currently constructing a factory demo Kit Fox albeit a 3. I'm attaching some pics on the progress we've made over the past few weeks...

Thanks for your interest in our R2800.

You'll find all other details (what comes standard, how to order, delivery, payment, specs revisited, accessories ...) on our website if you click on this URL:

The only ballache is the significantly higher weight. It's about 30kg heavier than the Jabi.

You definately have to fit a radial. Some other pics

:D :D :D

You beggars all of you (spelled with a u), you cause many dillemmas. I love the idea of a radial motor. I'm just scared off by the low tbo as well as the local representation issues.

Porker, should we plunge or be conservative, wadda u think

[FAWGie]

RV,

You only live once.....

Go on, take a risk ! Get something out of the ordinary

Overhaul for the R2800 will cost nothing like "blik" engine overhauls and you will only have to face that in 8-12 years from now.....where for R100k you could even revert back to a brand new 912S......

Jut think of that engine sound, the stares and the sofness admiration.....

[RV Sometime]

Does anybody know anything about the reliability & the initial snags with fitting this motor. Are there any of these motors in SA, etc. It might help with the descision making process.

[RV4ker (RIP)]

Live once. I go for the radial...., but your choice.

There is a Rotek at Rhino being fitted to a Gyro. Agent (Graham C) has the details. Maybe we shoot out there and have a look sometime.

PS
They are working on a firewall forward package for the Kitfox.....

A technically intrigueing motor, but I'm not sure I like it's look.

I would also err on the side of caution and not be the test pilot for it.

It's not a new entry into the market...lot's of them flying around the world - will be new for SA, though....

Being a Radial engine, it brings about the "classic" look and when you hear this baby fire up, it will melt you - believe me !

Cool,

but a 12 month waiting period!
