R-263
Posted: Sat Feb 18, 2012 9:49 am
We have some information on the R-263 up on our web site now. We only have
preliminary info at this time. The engineering team has finished most of the
drawings for the engine and some of the parts are under construction. It is
planned that the prototype engines will be made of machined from billet
parts. Production engines will have castings and forgings. The tooling will
be developed after the prototype engines have been flown for several hundred
hours. That is why production engines are scheduled for first quarter of
2006.
The following is preliminary info:
1. We plan to use Lycoming intake and exhaust valves, springs keepers etc.
to make parts easily available and avoid developing new valve sources.
2. We plan to use the Elliston throttle body system.
3. We will use a SkyTek starter and a 35 Amp belt driven Niagara air parts
alternator. The alternator and starter will be on the accessory case on the
back of the engine. It will use a standard Lycoming style diaphragm fuel
pump as well.
4. The cylinder barrels and heads will be basically the same as they are now
producing on the M14P.
5. The initial engines will use the "lunch box" style Bendix magnetos.
Savage magneto is building some up for us now. Future engines may have
electronic ignition depending on the .
6. The engine will be designed to use standard fixed pitch metal props and
will turn in the normal western direction.
We will develop the 125 hp version first. The 150 hp version will be the
same engine but geared with the crankshaft turning about 3200 rpm max. The
gear box will be similar to the M14P. The 180 hp version will be geared and
supercharged. The initial design will make provisions to add the
supercharger to he intake plenum.
