I just picked up a new heavy hauler wing kit that a guy had but never put together ,I am thinking about extending the wing when I build it for the fat avid,Is there any plans for this or has anybody did it and is there anything else I should think about when I start this project. I would think about changing over to the kitfox ribs but sounds like alot of work

The current plan is to use a Continental C-85. Possibly without starter to save weight
Did anyone read the thread on www.rotaryforum.com? It seems like this engine could have some real potential. If you read the power to weight ratio on this engine, you might even re-think your Subaru Ed I'm always skeptical of any conversion engine that can approach the power to weight of a 912 since the 912 used pretty sophisticated engineering, and was purpose built from the ground up. The hours that have already been accumulated on this Yamaha in aircraft are pretty promising though.

Luke,
Maybe I missed the info on your engine:
Still trying to figure out if you are going with Stratus, Honda, Corvair, Mazda, VW, Cont / Lyc, Rotec or Rotax -
That's the only "bolt-in" engines I can think of, although there must be a few more.

Thanks for the good info Doug, I knew I had some red grease at one time, but was beginning to doubt its reality!
I knew you were just sitting on it and making us wait for the good stuff.

Well, on a more serious note, any lithium complex with a NLGI (National Lubrication Grease Institute) rating of EP / GC (extreme pressure / applicable for high temp wheel bearing applications with disc brakes) and #2 consistency (consistency of grease ranges from semi-fluid #0000 to solid #6) will likely do just fine. Always clean bearings of old grease when unsure of compatibility with new grease.
FWIW, the grease I use in my tractor mower spindle bearings (and all other lube points), along with my plane and trailer axle bearings is red MYSTIK #2 JT-6 Hi Temp. It meets the highest performance standard of ASTM D-4950 Automotive Grease Classification System and is NLGI certified GC-LB for dual-service (GC for wheel bearing service and LB for chassis service). It also had the highest published dropout point of any wheel bearing lube (550*F) and lowest water washout and bearing leakage ratings when I compared MSDS sheets a few years ago. It is non-soluable in water, contains anti-rust, anti-wear, extreme pressure, and antioxidant additives to hold up well under high heat and wet, corrosive conditions. Available in both tubes and tubs at my local Tractor Supply, Home Depot and WalMart stores.

Hey Ed, I think you misunderstood... I'm going to go with an engine that you just bolt on and go I'm already adding too much complication to this project

Here is a link to the wings thread.. LOTS of good info provided by our resident historian / professor Dr. Holly.....

Can you point me to the technical data on the wing spars?
What info are you looking for specifically? Search for the "Different Wings" thread in the Avid Mk-4 forum, details the construction and material characteristics of each Avid wing design.

I have been paying $100 a kit for 9460 from Kitfox.
The spars are 2.5" x .065 wall 6061T6 for Kitfox and early Avids, and .083 wall for Airdale, Magnum, etc.

Luke,
There is a geared redrive for a Soob EA-81 on ebay now for $1200 - Donno what kind or how good - mine is belt redrive. I also have a spare Soob in storage with 31K miles on it.

Doug,
I will bet that there is a MIL-SPEC for that bacon grease. I ate a lot of it in the Army!
I'm sure it makes almost as good bear-bait as Salmon and pepper spray!

Very interesting. I've decided I have to go with a "bolt on" engine or I'll never finish this plane. Otherwise I would strongly consider something like this. I put a Subaru in our VW Vanagon, so I even considered that. I just know it would take longer than I think.
I think this is the thread for the Yamaha engine:

Ed - I've just been using my old bacon fat drippings...
I guess you dont have bears to contend with down there I bet it helps when you wrap one up though and have to overnight in the trees, you can just pull a tire and lick the ... ok, not gonna go there...

I had the same trouble trying to go to that site. On closer review, it looks like it might be a comma instead of a period just before the com. Easy typing error to make. I'll try typing it in. Jim Chuk
PS tried typing it and it worked.

OMG - may have to sell my Soob and buy a Yama! Right now my problem is getting to the site you posted in blue - every time I clik on it, the puter sends me back to the AFF site???
Are you supposed to put the < and > before and after the site name?
Guess I will have to type it out and go there - I was on their list a long time ago.
What rpms does the Yama run at?
TRACKWELDER: if you will post more about this engine, please start a thread in "4-strokes".
Thanks,
EDMO

Good to know. Thanks guys for the information. The reason I thought this guy's comments were interesting, is because I had heard similar opinions somewhere else before. I'm guessing that people who don't use the flaperons very much basically fly their plane more like a regular GA spam-can.
One thing I really like about flaperons is the fact that there are no moving parts inside the wing. It reminds me of the old RC trainers I used to fly that used "torque tubes" (music wire) to run the ailerons.

Could you PM me a price on the right wing if you still have it? I need a rib and endcap for a MK 4 Aerobat repair.
