Hmmm.

I've been using the address:

lugaprop@ukr.net 

Just finished my order with roman at luga here this week via email...  jared maybe resend it to him.

Yeah, I haven't heard of anyone who has run the ifa version.  Looking for reviews.

The Kool rebrand through airtikes is a bit more $ than if you order direct from ukraine.

Price from Luga direct (Ukraine ) for a 72" 3 blade scimitar  L 107 with a groumd adj. hub was about $640 (shipped) last time I inquired. 

I am told the weight of that prop with metal le protection and the hub is under 8 lbs!

Updated some info on Luga / Kool.

Also learned that Air Trikes offers an IFA hub for some prop models.  Anyone have experience with the IFA Kool / Luga?

The header tank?

Here's my guesses:

Low point in the system with a vent return which is most positive way to keep air out of the system.

With just a T fitting, In a steep turn or slip you might have fuel flowing really fast through the T from one wing to another.... and the fuel flow down to the engine might be reduced or even reversed (venturi effect).   Kind of like those fertilizer/weed killer bottles work where the garden hose flow draws up the solution.

Also it acts as a bit of a pressure reservoir with some volume to keep the engine feed constant.

Now someone smarter than me can give you the REAL reason!  (Inverted flight)

Yep.  Mine are 132.5

I'll probably need richer.

135 is what teal runs at near sea level with the snowmo box.  Anyone that runs a custom box needs bigger jets (all the way up to the 180s steve runs)

I'm planning that AFR guage to fine tune.  Also remember that a small change in float level will have a big effect, so if things are not making sense, check that.

Oh and jared, I talked to steve this morning amd he said he is too swamped with stuff right now to consider making us airboxes.

So I guess we are down to the snowmo airbox or a DIY approximation of what he makes.

Yeah, it is not optimum (too short and too much mmoi), but it'll work great as a spare.

Just like Jared, I'm planning on going to the 79" Luga.  Cheap and light = great, but the results steve henry posted (static pulls in the mid to upper 500lb range at realistic flight pitches, and a 600lb pull at a high static rpm test) was what got me sold on it.

I could only find waldo in 3/5  lol!

And jim if ya need a 72" lh taper tip for your collection,  fly on  over!

Sorry for the mixup Ed im MO!   My apologies!  The "other" Ed im question here is "Yooper Ed"... in the UP of MI.

And yes!  Your plane would be a great candidate for anyone shopping!  You know that I'd be on a flight down there if I were shopping!

EDMO, in this case I was referring to another Ed up in the UP of Michigan.

Good luck in your search for a plane Mike!

As far as the Yamaha, there are a few conversions popping up, but still a very rare motor in the air.

But I am working with an AFF member here who is at the moment pulling his Subaru and putting an rx1 motor in a KF4 up in the UP of MI.

He is not much of a social media / forum guy, but that helps him focus on getting szzit done!  I'm betting he'll have that plane done here in February sometime.  If you become more serious about a yamaha conversion, Ed's plane might be a good chance for you to look over to see how that is working for him.

You joined up on the Yam FB group yet?  My alais name over there is Anatoli.

Got that sled all ripped apart... and that pesky clutch off!  

Now for the fun part!  

Yeah, blindly sending money overseas has some risk!

Luckily steve and copro have good feedback in dealing with Luga.

By the way,  Air Trikes rebrands the Luga under "Kool", and some refer to the luga as an "NR prop", presumably the initails of the invetor (Nick Roman)

So:

LUGA = KOOL = NR Prop

With invaluable real world data from Steve Henry, I compiled my notes on Luga Props and posted over in the Yamaha Group.

Here's a link if anyone was interested in more info on these props:

(Sorry for the crazy link!)

Wish the bubble doors you are thinking about would fit my KF!  I'd sure be interested.  The KF factory kit price is fine for guys with deep pockets building a new S7... but a little out of my aviation budget!

Vance, Dumb question:  If I were to do flat lexan door replacement, could I put 3m tape on the frame then slap an uncut sheet on it, stick it down, drill and screw it down, then trim the lexan to the frame?  Roto-Zip it or something? 

Kinda a quick and simple "for dummies" job that a guy with my talents could appreciate!  LOL 

Setting it back farther might save some cowl rework time too?

Any plane prospects yet?  Target models / engines?

Yamaha with c box is left turning, like a 582 c box.

So opposite of 912.

So jared i think a little left is correct.

Avid experts, the question remains on up/down tilt.

Go perpendiculal to firewall?

(That was my KF5 answer)

I think we need a sub-forum for this too ed!

One really cool thing about the AFF forum engine (which btw is the best I've ever seen of all the forums I'm on) is that when a moderator moves a topic (like reorganizing into a new sub-forum), the original topic title remains as a link in the place it was moved from.

This really helps to keep members from saying  "now where the hell did that post that was right here go!"

Wow, there is alot of posts and discussion on HD gear / bush gear/ wide gear/ big tire  options!

Wonder if it is worth a new sub forum?

Move all previous topics in there.

Great way to have a one stop place for people to find info.

(No skin here...  I'm a float guy!  Just an idea.)

Exactly jim.

The avid guys are the ones to listen to on this.  Jared i would post a new topic with the question of engine angle on the avid model you have.

The way I did it on my kf is how the subaru was set up as a factory fwf kit.  You would want to come up with a way to convert that to how avid does it

my kf5 firewall is parallel to the fuse.

I went 4 deg left and zero up/down (level using cyl head top)

But I wont tell you how great it is until I fly it!  Lol!

So YOU'RE that creepy guy these guys are always talking about!

I kept thinking it was me!

LOL!

Welcome!
