What led upto the
decision?
Update 01/30/2000 |
Well, the best laid plans
often are shot to hell. Two days before
Thanksgiving I was on my way to work when a guy in a pickup decided to
take
an illegal shortcut and crossed three lanes of oncoming traffic that
was
doing 55+ miles per hour. I happened to be one of those oncoming
cars
and had nowhere to go and no time to stop or even slow down. I
hit
him broadside between the door and front bumper while another car hit
him
broad side in the back quarter. It did one heck of a job on my
car
but I was fortunate to not be hurt. The car was paid for and had several good years of service left but Allstate Insurance (The up-yours hands people) decided they wouldn't offer much more than salvage value for my car. After a bit of heated exchanges and my promise to take it to the state board of insurance we settled for $7000 for my car. (Never mind that the best price for a used car equipped similar to mine was $8200 and they had originally offered only $5000. You can guess where you will Ice Skate before I will ever buy AllState Insurance.) To make a long story short, I didn't have any car payments, didn't want any car payments, and had built an engine fund which was enough to buy my engine this spring. So below is a picture of my new engine! It's a 6-cylinder liquid cooled with 200 horsepower. Now if I can just figure out how to mount it to the firewall. |

11/23/99 - The selection has narrowed a bit. I have eliminated a New Lycoming IO-360 as an option. The almost $30K price tag for just the engine is enough to scare me off. The Continental IO-360 seems like a much better alternative at about $25K for a new one. That's still out of sight as far as I am concerned so I have looked at many alternatives. Among the alternatives I have considered are the Mazda Rotary from Performance Power, a Subaru from Crossflow Aviation, a diesel from DeltaHawk, and the Franklin 350. (Shown Below) |
And the winner is?
I am still trying to decide! I am leaning heavily toward the Franklin which is a certified engine with a good reputation. The main problem for me appears to be a conflict between the carburetor and the free castering nose gear. The carburetor is below and to the back of the engine. It extends down low enough that it might not clear the gear in any landing causing a flex in the gear. I am currently investigating several alternatives for a fuel injection system. The nice thing about the Franklin is that it can be purchased fully equipped with all accessories (carburetor, mags, etc.) or without. This allows the builder the option of selecting their own configuration. At about $15k for the engine without accessories it leaves me some room to make the modifications I will need and still keep within the $20k range. We will see. |
The Decision - Or Is It?
Update 08/05/2000 |
Prior to Oshkosh 2000, the top of my list was the Franklin 350. One had been installed and was flying on a KIS Cruiser in South Africa. I was encouraged by that and had discussed the possibility of obtaining the engine mount and all baffling from the same builder (professional builder). There were several issues to overcome including problems with clearance of the carburetor and the nose gear. I had hoped to eliminate that by going with fuel injection. Unfortunately, I could not find anybody who was offering fuel injection on the Franklin with the exception of Ellison. The Ellison is a throttle body injection and that still posed the problem with the nose gear. Add to that, a discussion with two builders from South Africa who were also building KIS Cruisers and familiar with the Franklin equipped plane. They filled me in on the latest details which were not real encouraging. Seems they are having a very difficult time cooling the engine and have already had to pull it to replace cylinder liners after 10 hours. (I have since learned that this was not an accurate account and the problems had more to do with the long term storage of the engine.) Conclusion: The technical issues and downsides were getting too much for me. That left the Continental IO-360 and the Powersport 215 (Rotary). I had, for the most part, put the Lycoming IO-360 as out of reach price wise, besides I have never liked the rough running characteristics of the engine. My preference was running toward the six cylinder Continental engine. I liked the Powersport Rotary but think it's over priced for an auto conversion and is not proven to my satisfaction for a family 4-place cruiser. (Possibly a good choice for RV-6 or such.) So, the list was getting pretty short by the time I visited Continental. (I did visit Lycoming but received little response and was largely ignored. Damn, they are proud of themselves.) Now we get to Continental. First I would like to say that I have never had better treatment anywhere than the Continental / Aerosance / Mattituck people gave me. They were outstanding and spent a great deal of time with me explaining all the options and prices. I must give them credit, they are trying harder and showing more interest in the needs of the builders and owners. Not only was I able to talk at length with representatives of all three companies but they introduced me to the owners of three aircraft flying their current offerings. I was impressed by both their professional attitudes and their products. |
Mattituck and Aerosance are both part of the Continental Engine companies. They were offering a new experimental engine called the XP-360. The XP-360 was the Superior XP-360 engine being assembled and marketed by Mattituck. Aerosance was offering a Full Authority Digital Engine Control (FADEC) system which would turn the XP-360 into an IO-360 with electronic ignition and computerized mixture adjustment. This was a combination that solved many of the problems I had always had with the 4-cylinder engines. It promised to produce a smooth running and reliable engine at a much more attractive price. |
AeroSance FADIC System
(Fully Automatic Digital Engine Control)
If you haven't taken a
good look at the AeroSance FADIC system,
do so, it is truly moving the aircraft engine into the 21st Century.
It's
redundancy and control of the engine should help both fuel economy and
engine
life at the same time. Just imagine being able to do an optimum
lean
on ALL cylinders and not just the hottest one. (and you don't
have
to do it!) What I liked most was when the pilot of an RV-6 with a FADIC
equipped
O-360 described the startup as sounding like and feeling similar to a
turbine
engine. It started smooth and slowly (NO not that slow!) wound up to
power
instead of lurching to a start. He also indicated a much smoother
operation
in all ranges, easier hot starts, and cleaner oil due to less fuel
contamination.
NOTE: AEROSANCE and the FADIC System are no longer in existance and the system has been orphaned (11/1/2018) |

The Order - Superior XP
IOF-360
Order placed for
Delivery in February 2002
Update
12/06/2001
The only sure Constant in life is Change |
Oshkosh 2001 and I still had not ordered my engine. Progress during the summer of 2000 was totally stopped due to an unbelievable summer heat wave that saw temps of 111 degrees F and lasted well into October. The winter and early spring proved to be a very wet one and I came close to giving up on my dream. The spring of 2001 revived my spirits and renewed my commitment to building. I decided that I was not going to waste another summer because of the heat and bought an air-conditioner for the garage. WOW! what a difference a little cool air made. (Electric bill shot through the roof!) The result was a very productive spring and summer of building. I had not ordered my engine yet so I decided that my trip to Oshkosh this year would be the best time to place that order. Once again, I made the rounds and looked at all the engine choices, old and new. Once again, I came to the same conclusion that I had reached the prior year, the Superior Air Parts XP-360 combined with the Aerosance FADEC System. Superior was now offering the XP-360 as both an assemble it yourself kit and in fully assembled versions. I talked with the representatives at length and attended one of their seminars but ended up leaving without having placed an order. I had made up my mind on the engine but not on the full configuration and/or rather I would try to assemble it myself. After a couple of months of discussion with Superior (and my wife) I finally placed my order last month (Nov, 2001) for the XP-IOF-360 engine. This is the fully assembled version of the XP-360 with the Aerosance FADEC system to be installed by Superior. I will hopefully will be looking for delivery sometime in February 2002. The price? Well, lets just say that it is more than I wanted to pay but, in my opinion, the best available choice for my mission requirements. I was totally sold on the benefits of the FADEC system and when combined with the Superior XP-360 engine, produces a combination that equals (I think it exceeds) the best available from Lycoming or Continental at a substantial cost savings. I could have gotten a cheaper engine for my plane but, I don't think I could have found one any better or that represented a better value. Now on to finding a propeller which will give the maximum performance from this engine. The choice of propeller may be almost as
difficult and expensive as the
engine. My first choice was the Whirlwind Constant Speed but I
have
learned that the nose gear on the KIS Cruiser is directly in the way of
the
govenor and there is no way to work around it. I am now searching
for
alternatives which current include the MT Propeller, an electric
constant
speed, the AirMaster Propeller, another electric constant speed, or
possibly
the Prince Propeller. With permission from Superior Air Parts I have scanned and included the descriptions of the Superior XP-360 Engine and the AeroSance FADIC system. I have also included an article from Custom Planes which covers the AeroSance FADIC system. (Click on logos for link to their web
sites.) Superior Air Parts XP-360

I
received the Superior Engine in 2002 and was moving forward until
November of 2002 when my contract with Shell Oil suddenly ended and
life got in the way of my build for a very long time. That long
delay resulted in a number of unforseen changes that would alter the
engine configuration. The FADEC system had to be replace due to
Aerosance being bought out and support for the FADEC being
dropped. I replaced the FADEC with an Electroninc Ignition and
Fuel Injection from FLYEFII. I decide on a propeller from Catto
Props which is fixed pitch with three blades. It is now the end
of 2018 and the engine has yet to be started. I had the engine
removed, torn down, inspected and reassembled with new gaskets and
seals. After 16 years in storage and in conditions that should
have been the death of the engine, it had no rust anywhere on the
inside of the engine. |
