So next question is what kind of cruise speeds are you seeing and with what engine /prop combo ,at what RPM on what model of avid or kitfox ,just out of interest. I have 31 inch bushwheels on my Model 4/1200 with Rotax 912UL 80 hp and the IVO inflight adjustable prop,also have 12 inch tailwheel and yesterday was my first flight with this setup and cruise at 2500 ft at 5400 RPM on GPS was 97 MPH which I was very happy with. Climb rate at 2000 ft elevation was around 1000 ft per minute myself [150 lbs] just over 1/2 tanks and 30 pounds baggage OAT 60 f.
Hi A friend bought an avid heavy hauler Mark 4 from an estate and can't find any weight and balance paper work or owners manual .We weighed it this weekend to start to get a weight and balance document done up for it . Anty help would be appreciated as far as the Cof G envelope number ect. THANKS
If you are wanting to clean the carbon and junk out of the engine,you can put MM in your cylinders overnight .I had 2 cylinder in my lycoming that had low compression , On compression check I could hear the air coming out the exhaust on one cylinder and the intake on the other low one. I had read that you could put a spoon full in the spark plug hole and pull the prop threw by hand a bunch of times to get it moving threw the engine and leave it overnight .So I did that ,next day pulled it threw by hand some more then put the plugs back in and started it and let it run up to operating temp.Checked the compressions on the 2 low cylinders and both had come up by 10 pounds but were still a little lower then the 2 good ones .So I repeated the process and next time the 2 low cylinders were up around the same as the rest.After that I added 2 ounces per 5 gallons when ever I went flying.Marvel Mystery oil made me a believer.
Herculiner is just like rubber and I can take my 31 inch bushwheels that have to coats on them and let the air out of them and push down on them till they go flat and the herculiner flexes with the rubber of the tires.
Have you considered using a hydrasorb with bungees like the supercub use .They provide the tunability with the bungees and the dampening of the shock.They are not cheap new ,but you can usually fine them used for a lot less. The piper PA 20 and 22 also use them but in a different configuration but will work the same way as they do in the supercub if installed in the strut. They bolt into the the strut and form the top section of the strut on the supercub gear.
I have had good luck with Herculiner, I wash the tires off real good ,then give them a decent sanding with rough sand paper to rough them up ,then clean them Real Good with xylene ,then I go in and if there are any deeper cuts I fill them by forcing the herculiner into the cuts with a putty knife let that setup for an hour or so if the cuts are deep. Before using the herculiner Mix the crap out of it and I don't thin it.I then use the foam roller that comes with the gal kit and start rolling it on nice and even and I mix it again every couple minutes in the can to keep the rubber compound mixed into the rest of it .I let that coat setup for 5 or 6 hours then apply a second coat and leave that for at least 3 or 4 days to CURE. I have good luck BUT I stay off pavement if possible and do NOT apply brakes and make a pivot turn on pavement or you will cause cuts in the herculiner and possibly the tire itself . GOOD LUCK Here are the actual instructions on how to use Herculiner on rubber. RUBBER--- Clean well using detergent or cleaning solvent, removing all oil, grease, wax and dirt. Rinse well and allow to dry. Roughen surface aggressively and then clean with Xylene (Xylol), Acetone or MEK cleaning solution. Allow solvent to dry completely before applying HERCULINER. HERCULINER coating will not bond to chlorinated rubber. More actual instruction HERCULINER APPLICATION TIPS SURFACE PREPARATION IMPORTANT READ CAREFULLY! HERCULINER will bond to all prepared, clean, thoroughly dry surfaces. On sound-painted surfaces, paint must be fully dried or cured to manufacturer’s specifications. The solvents in HERCULINER will not soften or attack properly dried or cured paint. GENERAL DIRECTIONS Always clean the surface of all oily or waxy contaminants by using recommended cleaning solvent–leave no residue. DO’S AND DON’TS DO • Thin HERCULINER with Xylene (Xylol) only. • Use Xylene (Xylol) if available, otherwise use Acetone or MEK cleaning solvent only for surface preparation. • Allow solvent to dry completely before applying HERCULINER. • Clean surface with strong aggressive detergent. • Ensure surface is completely dry and/or cured if recently painted, before applying HERCULINER. • Test doubtful surfaces with HERCULINER beforehand. • Apply 2nd coat within 24 hours of 1st coat application. • Wear chemical resistant gloves. DON"T • Mix any solvent with HERCULINER except for Xylene (Xylol). • Clean surfaces with lacquer thinners or any solvent containing alcohol, which will prevent HERCULINER from curing. • Assume surface is clean unless you have cleaned it yourself. • Apply HERCULINER if temperature is below 32˚F or above 95˚F. • Use a laquer-based primer.
Any of you guys with the a 912 on your avid heavy hauler Mark 4 willing to say what your empty weight is? Just looking to get a ballpark weight. Also wondering if anyone with the above has full lotus 1260 floats on could give their empty weight? THANKS
