OK, you didn't ask for it...........well some did offline with my cheapest/easiest statement yesterday.
Here is the the state of the project http://rvflying.tripod.com/aero1.jpg Here is what I got via truck line yesterday http://rvflying.tripod.com/aero2.jpg It is a rotary 13B which will produce 180HP+...........I bought it for $650 delivered. To rebuild the engine I'll have to buy an aero rebuild kit, not auto rebuild, for right at $900. Gear reduction will run $2440 which will allow me to run a metal prop for IFR. Computer engine moniter for aero use, $875, dual aero designed fuel pumps $95 each and about $500 of extra parts. As you can see, cheapest/easiest is coming into play:-) For engine/redrive see the following: http://www.rotaryaviation.com http://rotaryresources.com Next the issue of engine mount/gear mount to fit my 0-360 cowling..........hum, I sure don't want to have to tackle this.........let's try: http://www.conversionconcepts.com/rv-6-7.htm Since I already have a new Dynafocal 1 engine mount and match drilled gear legs, I posted a message yesterday, .......I sold them last night so as to offset the purchase of a new mount. I'll order two new undrilled gear legs for $170 each and have them match drilled to the gear attach points on the new engine mount. No toe in adjustment as you just put a bolt in and the issue is moot. Back to the issue of water-cooled and reduction drive. The more I looked at the rotary the more bullet proof it appeared. I know that term is used way too much but here is my take. The rotary will run at operating RPMs without water for somewhere around 1/2 hour before the apex seals around the rotary start to come apart. After they come apart, you certainly lose compression and a resulting loss of RPMs. However, it still continues to run as no metal is rubbing on metal. You won't be able to restart it but it will continue to produce minimized horsepower. These things don't mechanically break or blow up. With so few moving parts and no jugs to pull or valves to lap, maintenance is at a minimum. The redrive unit from Tracy is a proven unit. It is a final product and will turn a wood or metal prop. Sen. makes a prop for this drive especially for the RV. The engines will efficiently and reliably produce 180HP+. Someone slap me..............I must be asleep at the wheel making such a decison:-) OH, KR related.............you can get a rotary to fit:-) Dana Overall 1999 & 2000 National KR Gathering host Richmond, KY RV-7 slider, Imron black, "Black Magic" Finish kit Buying Instruments.
