Hi. My name is Rob Helt. I have been following the builders list
since inception However I never felt that I could offer much useful
information when there are people like Wayne, Bob, Mike and numerous others
that are flying and have a lot of practical experience. I am building a
Super Rebel which will hopefully be flying by the summer of 2002. What I
have researched extensively are engine choices for the SR. As Wayne had
mentioned in his previous message the M-14P is probably one of the cheapest
engines available to date. I remember talking to Darryl about this engine
before the SR prototype was even flying. Until recently he has never
recommended this engine. As Mike mentions the only flying SR with the M-14
is up around the Sudbury area here in Ontario. I have seen the plane and
the modifications that were done to it. Unfortunately the factory
re-enforcement's for this engine are going to be considerable and will
entail(as far as I know to date) the opening of the wings(including tanks)
to re-enforce the spars(front and main). The amount of work therefore will
be considerable for what I think will be a small gain (increase in useful
load of maybe 260lbs). If I were to buy a kit now I would definitely go with
this combination as the work involved when building is not of any
significance. The engines that Murphy will be using are the NEW built M-14
from Romania. They have a number of castings of Russian origin and are using
these to produce new engines. Other sources for the M-14 are Shadetree in
the US which have a number of new old stock engines. Be careful when or if
you buy from an advertisement i.e.. Trade a Plane. There are a number of
engines out there that are actually runout with a new log. These engines
are used in a number of aerobatic planes so parts are readily available as
well there are a number of good people who can help with this engine and the
needed accessories. Besides the Yaks and Sukhoi's the modified Pitts 12
(the macho stinker EAA July 1999) and the Culp special all use the M-14.
The above article is very informative And Jim Kimball of J.K.Enterprises is
very helpful.
Now for those people that are building a SR and want a radial engine
but don't want to go to all the extra work of re-enforcing their present
kit there are still a number of options. There are a number of these radial
engines around that are de-rated i.e.. range from 280-315 hp. Since the SR
was initially rated for 300hp. I think that any of these option's is
feasible. I am going with the M-462 which I have purchased. This engine
is used on the Zlin-37 which is an agricultural aircraft. Overhaul is
recommended at 800hrs. and the factory will overhaul these a max of 5X. If
anybody is seriously interested in this engine I can put you in touch with
my supplier.
Hopefully the information will be useful to someone. I have nothing
against the Lycoming or Continental engines out there except the price is so
prohibitive as is maintenance.i.e..cylinder for a lyc.=1200-1600US. vs. the
M-14 300-400US(as Wayne said you do the math)
Somebody previously asked about the fuel burn. Max. continuous
operation of the M-14 at take-off (360hp)=5min. and cruise can be as low as
59%. The fuel burn can vary but averages out to 14-15 gallons/hr. Nice
bonus is that the comp. ratio =6.2:1 so you can pump at your local Esso.
If anyone is interested in one of the alternative radials then contact
me off the list as I really do not want to advertise for any one individual
or company.
Have a Merry X-mas;
Rob Helt

customerThis is from a message I received from the guy who built the first
removecompleted SR... which has an M14-P and is on straight floats... he prefers
his plane called a baby beaver. You may recall at some point Murphy had
pictures of his plane on their web site... however, they gave him such a
hard time over putting this engine on his plane that he asked them to
aroundthe pictures, and now he doesn't like to associate his plane with Murphy
much. I have several pictures of his plane... goto:

--------------------------------------
The performance is great, its a true STOL aircraft on floats, takes off
short and lands short. So far I have mostly been running the engine
for65% power and 25 inches. Cruse is 120 mph on floats at those settings.
Fuel consumption at these settings is around 12 gal/hr. Floats are
PK3500's.

PS He's never had this plane on wheels...

My next door neighbor at the hangar is building a pitts model 12
he claims 15-17gph at cruise and 30gph at full throttle
