    Turbo, I read all of your older post on when you were learning to fly your Avid. I am guessing you have a few more hours under your belt now, so what is your opinion on flying it now? I am guessing you still have the standard gear (narrow) installed.

    I suppose I might have to wait till I finish the airframe and weigh it complete with cowling minus engine and prop and see what I have to play with, weight wise. According to the paperwork, it originally had a 503 mounted and flew a hundred hours or so with it. For whatever reason the builder decided to install a 250 lb Subaru in the nose, which made a 725 lb aircraft with a gross wt. of 950 lbs. Doesn't seem logical.

    From all I am reading and what info is out there (quite a bit) mainly from across the pond, it is a little heavy for a model 2 Kitfox.  Most come in around 165-175 lbs flying weight. A model 2 needs to stay in the 130-140 lb range at the max. Which leaves few choices for a four stroke.  Even if the weight was acceptable, by the time you add ballast to keep the CG in range, you are pushing 180-190 lbs.  Which leaves the 2 stroke as about the only option except maybe the Jab 2200.  We are not overflowing with lightweight aircraft engines.

    I would prefer an engine that is available and popular here in the US. Mainly due to parts and service being available without going across the pond. It appears to be leaning to 3 options as of now. The 582, which will go away someday in the near future, the Hirth with its less than stellar reputation, but currently in production, and the Jab 2200 with its shady past that it might have fixed with the newer ones. As it stands now, the 582 is probably the most popular due to gobs of them out there flying and most problems have been dealt with by experience. The Hirth is coming up as a solid replacement but not a lot of owner info out there to go by. But parts and service are available within 4-5 hours from my location. This isn't just my issue, we are all in the same situation sooner or later. The older Avids, Kitfoxes, and many others which can't handle a 912 type engine are going to end up with no available engine choices eventually. Every new airframe kit is based around the 912 or bigger engine which leaves us lighter guys out. Very little work is being done on new lightweight engines for ultralight type aircraft. Maybe I am off the mark, but we all have some skin in this. Unless you are the Trent Palmer type with money or somebody to pay for it .

    I looked at the BMW and its available in stock form about everywhere. It does require a bit of work to make it aircraft suitable. Dick of RV fame said there wasn't enough time in one's life to design an airframe and an engine, too. I already have the airframe, but I am old and probably not enough time to design an engine or highly modify one. This Kitfox will be a local flyer and not a cross country machine.  1 to 2 hrs max flight time.

    Getting close for an engine choice
    Guys, getting close to having to make a choice on an engine for my light kitfox model 2. Have been considering most available 2 strokes and some 4 strokes, but no clear choices popped up. As it stands right now, the Hirth 55HP 3202 is showing promise but nothing definite. Before I'd go with a 582, I'd consider the Jab 2200 for basically the same weight.  I know a 582 is reliable in most aspects but I'd prefer air cooled if at all possible. Anybody have any solid prospects that comes to mind?  There are some untested good ones out there and some junk as well. Maybe this group has some in mind that I haven't thought of.

    No insult was intended at all!  The oil debate has been around since there was oil. And I doubt if there will ever be a final decision. All one has to do is go on any 2 stroke group and you will find an oil debate going on.  Ask 10 different people what oil is best and you will probably get 6 or 7 different oil types.

    That was quick! I couldn't sell a model 2 that was built, sandblasted, primed and painted, complete with cowling, gages and interior, for 7500. And it was even registered with paperwork. So I am restoring it to new condition. This is probably my last homebuilt so I'll build it to suit me. Somebody got a pretty good deal on yours!

    My oil is better than your oil !  Of course you'd have to tell what your oil is.  Bubba's ex-girlfriend's sister's ex-boyfriend used that oil and he said it wasn't any good. Haven't we all heard that before?

    Getting an old one re-registered isn't a big deal, but it is a PITA. You can get a copy of every piece of paperwork ever filed on it from the FAA. I am going thru the same issue. I have the FAA doc's and its now registered in my name. But I am doing a back to new rebuild on my model 2 with a new engine, new logs and basically a new aircraft.  I really paid too much for it, but having a "new" Kitfox model 2 for 15K or so is a good investment considering the price of kits and aircraft now days. I fly generally by myself most of the time, do a little off field flying, and generally run gas thru the engine, so a solid model 2 is a good match for me. I weigh 140 with a full cup of coffee so a 950 gr wt. isn't a big deal. Paying 30-40K for a new "Fox" is!  Another "hillbilly" passing thought.

    I think the Stewart System paint is around $300 a gallon. Pricy compared to 40-50 a gallon for good quality latex. I did use their glue and filler and its around $200 a gallon but its easy and a gallon of each will do a Kitfox.  Another final option is after final painting, spray a coat of their clear over the latex and it protects everything. This is the first time I've used the Stewart System so I am in the learning mode on this system. So far its been pleasant to work with. The video's make it look so easy a hillbilly could do it.

  14. Allen Sutphin added a post in a topic Anyone ever use a sea doo engine?   

    I, myself, am not too concerned anymore on single ignition non-aircraft engines. Most have high energy ignition systems anymore and a plug fouling out is rare due to the hot spark they provide. The GA mags fire in the 35K volt range which happens to be in the middle of the fouling range.  The modern systems fire at 80K volts plus or more so fouling isn't a big issue. You have a better chance of buying a bad plug than having one foul out. That's why most auto makes state at least 100K miles before plug changes. I don't know the volts that Rotax fires at but even 2 strokes rarely foul plugs or at least the non-points engines, anyway. Anyhow the GA engines are old technology. But they still work.

    I plan to use latex house paint as a final color. It will go over the ekofill just fine. Most either have it too thin or too thick which translates to a poor finish or paint problems. It does help to roll or foam brush on the first coat and lightly sand it then spray the final coats. In my career, I have made about every mistake one could make when painting.  Some of them were expensive, too.
