Availability and Lead Time:

The lead time varies and is dependent on at what point we are at in the production cycle. We manufacture in a batch process with all engines allocated before hand in a forward ordering process.

At the moment we are at the assembly stage of a current batch of R2800's and R3600 and manufacturing parts for a subsequent batch.

  • Current Lead time for R2800 is 3-4 months
  • Current Lead time for R3600 is 3-4 months

These times can and do extend once all engines from a batch are allocated.

So in summary: If you want an engine the best thing to do is pay a 10% deposit and place the engine on a forward order. A further benefit being that once a deposit is processed the price of the engine and accessories is fixed for 12 months.

What Comes Standard - Best Value for Money:

In your evaluation as to value for money please note that each Rotec radial is supplied with the following as standard:

  • Bing constant depression carburetor with coupling and hose clamps.
  • Diaphragm fuel pump (driven via gear train from scavenge pump)
  • Complete set of weldable attachments for building a mounting frame.
  • Complete set of rubber cushions for each engine mount point.
  • Complete prop hub.
  • Complete Igniting system including:
    • Dual Distribution (Electronic + Magneto for R2800 and dual Electronic for R3600).
    • Ignition Wiring Harness (dual for R3600)
    • Ignition Coil (dual for R3600)
    • Ignition module and heat sink cream (dual for R3600)
  • 12 Volt Starter Motor
  • 12 Volt Alternator
  • Oil Filter Block with inbuilt sensor ports for pressure and warning light.
  • 2 Filters: one for the block and one for the in-line filter to the geared scavenge pump.
  • 3:3 Reduction Gearbox (planetary) providing high torque

Furthermore the Rotec being air cooled means no radiator needs to be purchased and no water is lugged around in flight.

For most conventional "flat" engines all the above are normally quoted as optional extras. With this in mind the R2800 and R3600 become best value for each dollar spent.

Overview of Performance and Specs

There is more to a Rotec Radial other than smell, great looks and great sound - as it rumbles up with throttle the wash from the prop indicates an awesome amount of available power far beyond its horse power rating.

This useable power is a result of the inherent efficiency of radials in general, coupled with a the 3:2 reduction gearbox providing an exceptionally high torque curve which is basically flat over operational rpm. The final result being that both radials swing large props at relatively low rpm (equals efficiency).

In the case of the R2800 it swings a two blade 76" diameter prop at 55" of pitch at 2000 rpm when cruising (rpm measured at the prop). The torque curve at the prop within 1850 and 2100 is basically flat and comes in at 245 ft lbs. The torque and performance of the R2800 exceeds that of a 130HP O-290.

In the case of the R3600 it swings a two blade 84" diameter prop at 62" to 67" of pitch at 2000 rpm when cruising (rpm measured at the prop). The torque curve at the prop within 1850 and 2100 is basically flat and comes in at 318 ft lbs. The torque and performance of the R3600 far exceeds that of a 160HP O-320.

Delivery and Freight

Terms are Ex factory but we do assist and arranging freight services and quotes.

Over many years and many deliveries we have established that when all charges are totaled there is little difference between sea freight and air freight when dealing with a single engine delivery (sea freight only becomes economical when the number of engines being shipped is greater than 2).

To remove all the hassles involved in freighting engines to the USA we have a special on offer. Rotec will take on the full responsibility of air freight, fully insured, all paperwork completed, cleared customs an engine and accessory package to your door (to any location in the USA):

  • R2800 + all accessories will be air freight from Rotec's door to your door (customs cleared etc) for $1100USD
  • R3600 + all accessories will be air freight from Rotec's door to your door (customs cleared etc) for $1195USD

In short let Rotec do all the work in freighting the engine package to you to anywhere in the US at the above fixed prices!

For other countries the authorities in these countries may require payment by way of duties and taxes. However, in some but not all instances the same air freight costs apply as quoted for the USA. Please check with Jim at Rotec (mailto:rotecadmin@bigpond.com) who will research the best option on your behalf without charge.
