Some of you are at the stage of needing to consider what power

to use in your project, and are looking for a good buy on the Rotax 912

series, but I have notice quite a lot of discussion about the problems

associated with it's liquid cooling system, and other issues.  

	Why not use the Franklin 125hp engine, which is available at a

price that is hard to believe, because of it's modest level,

comparatively ($6,900).  They even are aware of our Kitfoxes according

to their ads, so why aren't we seeing these installations talked about

on our list, and articles in the magazines?  I must confess, I don't

understand why this engine isn't the main one guys are talking about now

for airplanes in the class of the 5 thru 7 Kitfoxes.

Just a general comment about the Franklin engines...seems of the maybe

half dozen folks I've talked to that flew/owned one...they either swore

BY THEM or swore AT THEM!!!  Probably the same on most engines out

there...



Hard to beat the 912 series though...pricey but definitely get what you

pay for...



Is anyone aware of anyone making motor mounts for the 912/series

5,6,7's???



Will need one before too long.

Weight?? Do you have an engine weight comparison chart. I dont.

Duane,

I seriously considered the 125 hp Franklin.  In fact that is the way I would

have gone if I had chosen to go with the heavy engine.



But I finally decided to go light and it came down to the 3300 Jabiru or the

912S.  At that time the Jab didn't have a very long history, so I went 912S.

Now I am very happy with the 912S.  It make the 5/6/7 a Light Sport

Aircraft.  Couldn't do that with the Franklin.

Good question Paul.  Here's a great source for engine info whether auto

conversion or aircraft.  I have no idea how accurate it is, but it gives you

some idea.  Have fun.

I looked at Franklins back when I was trying to decide

about my engine.  They haven't gotten over the

reputation of being 300 hr TBO engines, I guess.  I

thought someone on this list had one though.  Any

current experience out there?

<mrclary(at)erols.com> Milt Cary was one who purchased a Franklin.  I don't 

know how up to date the e-mail address is.  Roy Meyers was the first to 

put a Franklin  in a Kitfox Safari.  I don't have his e-mail , and 

haven't heard from him for some time.     Norm

Hi Jeremy,

I have a mount for a 912 series 6 I will sell cheap.  I switched to the 7 

fwf and do not need this one.  You will still need the ring from rotax 

though.  Just give me a call or email me off list and I'll get it sent out 

right away.

What's the best way to learn details about the Kitfox 7, like construction  

materials & details of various components, weight of basic airframe with  

specific engines like 0-200, performance with 0-200, Rotax 100+ h.p., fuel tanks  

vs folded wing transport, & cost of engines, props & "projects"? My  interest 

is cross country with long range tanks & low weight pilot/passenger  7 little 

luggage.

 

Thanks,  F. Wood

One consideration is Sport plane or not.  My 5/7 has a gross weight of 1320

and is a LSA.  Empty weight is 776 lbs.  So I can fly as sport pilot when

(if?) my medical becomes questionable.  The O-200 makes this much less

feasible.

Kurt:



	I believe that the engines are built in Poland, and may include

some improvements in quality over the old design, but I do not actually

know this, but my point was to raise some awareness, and to get some

discussion going.  If they are junk, then that needs to be said, but I

just found it to be odd that no discussion at all was going on about

them, while people are busy adapting car engines, and working with

liquid cooling systems.  Have the magazines done any articles on them?

As Lowell says, it could become an engineering project to do the

installation, but some of the guys who are in the group could be up to

it.  It could even turn out that there are reasons that it would not be

a good solution, but we wouldn't know this without some discussion and

information transfer.

I am installing a Franklin in my Model V.  I have yet to start it but am getting close.  So far it has been a perfect fit for the V.  The guys in Fort Collins that sell the Franklin made up a mount for the Kitfox along with an exhaust and the quality has been top notch.  So far I have not had any surprises mounting it but again, iI have yet to run it.  Any questions about it let me know.

Will this work with the round cowl Tim?  Which cowl are you using?

Deke,  I am using the "straight" cowl for the 0-235.  It has been a while but I believe iI ordered the firewall forward kit for the O-235 and then had Franklin make me a mount.  But everything else such as the cowls, firewall, etc fit very well with the Franklin.  The carburater is about the only thing I have had to engineer myself and again I have not run the engine yet but I ordered the Aero-vee carb from Sonex which is a fairly simple and straightforward carb.  I was planning on using the Ellison carb but it requires a straight run of airflow that I could not figure out a way to make work.  I will soon see if I made a good decision or not!

I used the Ellison TBI and made a plenum box with the air entry on the right 

rear side of the "box" (which is actually shaped sort of like a tear drop 

with the pointy part coming out to the right of the oil resevoir).  I used a 

NACA vent on the side of the lower cowl to bring air in to a carb heat box 

mounted to the RH firewall footwell.  More than one way to skin a cat, but 

it will still be a while before I can claim success...

Thanks Tim.  Do you know if the round cowl will fit over the Franklin?

Keep up updated on how things are going with the install.  The more options

we have the better.

Do you have any photos you can put on Sportflight.com/uploads Milt?  I'm

having trouble getting a visual on what you're describing.

Deke,



I'll have to break out the digital camera and take some pictures.  Back when 

I did the work all I had was 35mm..
