    Chris, that is very similar in principal to what I and many others have done. However, I used seat belt material.

Mark Twain Jim: I'm nearing the completion of a Kitfox 7 and have looked at this issue fearing the same possibility. My solution was to fabricate a couple of slings that go under each side of the seat (total of 4 in all) andwrap around the structural tubeing that suports the seat. The slings are fabricated from steel strapping normally used for pipe hanger material that can by purchased at most hardware/home improvement stores in the plumbing department. The strapping comes with pre-formed holes so once you have the correct length so that the fiberglass seatpan rests on the slings, secure with AN hardware. After installing the slings, the seats are very solid and will withstand much more load than the stock setup. Chris ------------------------------------------------------------------------- -----

    PLACERVILLE, Calif. -- Two Northern California residents were recovering Thursday after the experimental plane they were flying crashed in a field near Folsom Lake College. The crash reduced the small white plane to a crumple of tangled metal, and neighbors who rushed to the scene said they were shocked to see a man and woman crawl away from the wreckage. El Dorado County Sheriff's Deputy Phil Chovanec said the two Cameron Park residents were in stable condition at a local hospital. Their plane had taken off from Cameron Park Airport bound for Idaho at 6:15 a.m. It crashed 15 minutes later near the El Dorado campus of Folsom Lake College in Placerville. The Federal Aviation Administration is investigating the crash. Found this in local paper. Park yourself in front of a world of choices in alternative vehicles. Visit the Yahoo!

    I did a little research on my kit. It was ordered in 03/31/97 and delivered 04/30/97 from Skystar. Does anyone know if the tanks would have been made of the new Aflac resin? I also found a packing list that includes Kreem Fuel tank liner, Quart. Makes me think the switch had not been made on the resin yet. Maybe the Kreem is the amber stuff comming out?? On the web I find it says it is "Resistant to alcohol and gasohol; withstands most octane boosters" but who knows back in 1997. -------- _______________________________________ Giovanni Day Model 4 speedster 912 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=132500#132500

    Giovanni, My kit was made mid '99 - supposedly well after the switch was made to the new resin - and the kit included Kreem. I didn't use it. No problems in 180 hours. I think your kit was after the change too, but hopefully someone who knows for sure will respond.

I am sure we will hear all the details from Lowell, John. But I often drive my car, looking at fields along the road and thinking: Hum, from above this would look like a nice place to land but look at that shallow trench or that obstacle. Here in Norway, many such fields are on hill sides and quite steep ones. From above, it all looks flat and friendly. > Could the Zodiac have a similar design issue with the fuel flow? It could very well be, John. Since the engine started again without problem on the field, we will never know for sure what was the cause but carburettor icing was the prime suspect from what I hear. I don't know if that plane has a header tank or not but I am glad I have one. Cheers, Michel Verheughe Norway Kitfox 3 - Jabiru 2200 Do not archive

    # 1492 was equipped with 13 gal wing tanks and one of them has split a seam while being removed. Right at the point where the cut off rib attached the top and bottom can be separated a little. I discovered it while leak testing before gluing them back into the wings. While I can for a thin blade into the 1" split it is far to small to force Hysol or any other thick adhesive in there. I am contemplating repair options and would like to hear what has succeeded or failed for others. Dave Goddard- Mod IV 1050/582 do not archive

Since most of you run all the time with the pump running, I'll start dong it also. Peter, I did a compression test and found that my clinders varied from 80 lbs to 135 lbs dry, and 140 to 220 lbs wet. Does this mean that I need both a ring and valve job (with your stainless steel valves)? Layne

    50mph stall when landing a speedster at full gross. NO WAY. I can say that, I have the same airplane. All I can say is I went to the fly in this weekend and I was very supprised at how fast everybody was landing. I think everybody needs to learn how to SLOOOOW down when they land. Way too many sqeekies. If you don't think it's necessary, think about when you need to land off field some day, lets slow these babies down. After all they are a kitfox. -------- kitfoxmike model IV, 1200 speedster 912ul building RV7a slowbuild wings, fuse, finish kit &quot;if you're not getting razzed from pilots or the FAA then you're not flying enough&quot; Do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=132551#132551

    I bought my Model IV kit in 1996 and used the Kreem in the tanks. I have been flying since 2000 and have had no problem with fuel contamination nor water in the fuel. My fuel lines are a combination of the rubber hoses and aluminum that came with the kit. The site gages turned dark, got brittle and one of them broke departing Oshkosh in 2006. I replaced them with nylon tubing that is not as transparent but still works and has not been a problem.

    Subject: kitfox trim.
    I recently purchased a kitfox 4 1200 with a rotax 912. When we try to trim it out in cruise speed there is still a tendency to nose down... I'm lazy and don't want the back pressure... Do any of you guys use elevator trim and just move the flaperons full forward ? Also, it's a torquey little beast at full power... It likes a lot of right rudder on climbout... Should I bend the tail trim a little further and use the rt. rudder less on climbout our just get used to it ??? Any comments from you old pros will be gladly accepted...

    Well.. I'm no "Pro" but I'll chime in with my limited experience :-) Are you trimming with flaps or do you have the motorized trim tab option? I have the trim tab on mine and there's plenty of trim authority to trim for strait and level. In fact, my trim setting is forward of neutral at cruise. As for yaw: I too need lots of right rudder to stay coordinated on full power Vy climb. On the other hand, I still need a little left rudder at cruise. I spend a lot more time at cruise then I do at climb so that's more of a factor for me. I guess it's a trade off either way but there's no escaping that your feet are going to be a lot more busy in a Kitfox then they would be in your average Cessna. -------- Luis Rodriguez Model IV 1200 Rotax 912UL Flying Weekly Laurens, SC (34A) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=132561#132561

    Subject: Re: Seat Reinforcement
    Clem, Just my 2 cents, but why Balsa? It may be light, but wouldn't provide much strength or support due to the span, if the seat load falls on it. Spruce, at a little more weight, is much stronger and could possibly support the load. However, the real problem with both (especially the spruce) is, there is no crush zone. So after the small seat cushion and tush, your spine gets to absorb the g -load. Ouch! It seems the web material or seat belt material has some give and then retains the seat pan over the controls. I went with the webbing, but either way, I think doing something to keep the controls from getting jammed is necessary.

I like the flaperons to have the same angle of attack as the wing. Once you've checked them, then I recommend adding an elevator trim. I like it better than trimming with the flaperons, though I confess I've not been able to ascertain a big speed difference either way. >Also, it's a torquey little beast at full power...
