Hi,

Am awaiting arrival of a Proctor Eindecker,and am just asking what engine would be suitable,i have thought about an ASP 1.60 twin,which is my first choice,second would be a saito 1.50,but the twin is winning at the moment!!,can you confirm the ASP would do the job,i don't want to over power her,just fly in a scale manner,but i am open to suggestions for other makes models etc

Many thanks

Eindecker

Hi,
I would definitely vote for a 4 cycle twin made by any of the well known manufacturers. My 1/4 scale Proctor Nieuport 28 is powered by an OS 160 four cycle twin. It has a short take off and will loop from level flight. My smaller Proctor Nie 11 is powered by a Saito 100 twin which is an absolute jewel of an engine but is too small for your purposes. One of the advantages that is not often mentioned to these twin engines is low vibration. When you have lots of scale wires, turnbuckles, and scale framework you don't like to see it torn up by a big single or gasser, not to mention the potential problems with increased radio interference from vibration.

There is an experienced Proctor flyer on this forum who is planning on building an Eindekker in the near future. I'm fairly certain he decided on a Laser 200 to power it. His name is PITTSDRIVER and hopefully he'll join in here. If not, you may want to email him for additional info. Best of luck with your project and hope to see some building pictures here soon maybe?

Dear EindeckerIII:

The PIPE Here again...and I JUST started on the CAD drawings for my 1/4th sized M.5K/MG Eindecker on Saturday!

I've been LONG considering the RCV SP-series powerplants for my "pre-production" style EARLIEST of all Eindecker variants, and where the M.5K/MG only spans 88 inches, and is 5-1/2 feet long in the fuselage department, the RCV 90SP, with its capability to turn a BIG 18-20 inch diameter, 10-12 inch pitch prop at an amazingly SLOW 4500-5000 RPM, due to its unique "camshaft-speed" design, looks like the BEST one for my needs!

I had also considered the RCV 120SP for my early Fokker, but Otto Kdurna, who REGULARLY posts in the "RCV Support Forum" here at RCU, stated the 90SP WOULD be a good choice for my very early Eindecker as well.

If you ARE going to do the full-blown Fokker E III, straight from the Proctor kit, though, I'd bet you'd be best off using the 120SP...as it CAN spin a full blown TWO FOOT diameter prop, of about 12 inch pitch, at those RPM figures quoted here for the 90SP...and a 24 inch prop is fairly CLOSE to scale size for that aircraft, when done up in 1/4th size. The E III also spans 100 inches in quarter scale, and the 120SP should be a GREAT match for that airframe's wing span!

Just check at http://www.rcvengines.com/model_home_page_full.htm , and click on the SP series engines to check them out...there's even downloadable FULL SIZE DRAWINGS of ALL the SP series engines there, in Adobe Acrobat PDF format, for you to access and print out!

Consider the RCV SP series "camshaft speed" engines for that model...and I'd bet IT would be the perfect match for your Proctor E III version!

Yours Sincerely,

The PIPE!
