    Who knows what they are made of now Jeff. That was a couple owners ago. BUT I still have a set of Fiberglas Legs with the fittings at home. Makes it ride smoothly but so flexible it would toe in when pulled backward into the trailer,making it hard to pull so I put the aluminum ones back on.

It causes no problems but when the plane is sitting, the wings are not quite level. If I put a straight edge on the bowed gear leg, there is about a 1/4" gap in the center. Is it ok to straighten it with a press of some type? I think I asked Travis at Kolb once and he said no, but he might have thought it is bent quite a bit more than it really is? I'm thinking about leaving the gear leg on the plane and taking channel iron to the top side and using some blocks then taking a strong clamp to press the bow out. What do you guys think? Is it ok to bend a slight bow out of one gear leg? I think this Firestar was built in 1997, built by Gary Aman. The gear legs are light in color, looks like aluminum, but are probably stainless spring steel something like that. > > -------- > &quot;Life should be lived as a bold adventure, I refuse to tiptoe through life just to arrive safely at death&quot; > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=421296#421296 > > > > > > > > > >

    Morning Folks: Heading for the airstrip, then south to Lakeland, this morning. Weather looks good all the way down, 420 sm. Probably take me 5 + 30 to get there, unless I can find a good tailwind. Talked to Travis this morning. The Kolb trailer is in place at Paradise City. Hope to see a bunch of you folks this year. john h mkIII Titus, Alabama

    I managed to bend mine too. The original legs are made out of 7075 aluminum. Kolb wanted $125 apiece for them. My leg bent & splayed out & it tracked badly so I went with spring steel. When I pulled the leg I noticed that it had been replaced in the past more than once by the holes in the frame & legs. I built my own legs out of 4130 steel & had them heat treated. I don't expect to have to straighten them but John Hauck says it can be done. I had about $250 in the set with welding, machining & heat treat.

    >From what I have so far read, his problem is minor at the very worst, and the last thing he needs to do is try to correct something that could best be described as "cosmetic". I went through the straightening exercise at least a couple of times before I gave up and went to the steel gear legs. My plane always dropped the right wing first and the bends were always in that side of the landing gear. If he merely unbolts the gear leg in the socket, turns it 180 degrees, the next time he drops it in the leg will again be straight or bent in the other direction. If he does decide that he has to straighten it, then he should find a good "press" ( someone should have one among his friends) and suspend the leg bent side up on some 2x4's, stick another on the high side and apply enough pressure to go a bit past straight. That is of course necessary to allow for the amount of spring in the leg. He should be very careful to not scratch the alum. which is the reason for cradling it between wood. Quite frankly wimpy alum. gear legs, have caused me more trouble than any other feature of flying. I would advise every one that the change to 4130 spring steel gear legs will pay rewards that will make the change one of the best things that you could do for yourself. The plane lands better with taller legs, and the 4130 is forgiving enough that a sloppy or rough ground landing will not cause damage to the plane, you will just bounce back into the air. The theory is that the alum will bend thus preventing other damage to the cage. However if the leg bends and you are carrying any speed, being whipped into a ditch can cause some serious repairs, or a wheel snapping off from hitting a rock can cause you to see the world from a bit different perspective, such as upside down. Just a hard won lesson that I have paid for three times. May not work for you, but I wouldn't bet on it.

    Perfect! I have been looking for an excuse to get a press. I think maybe I should order one now so I have it if I ever do bend the gear. Good preventative medicine don't you think? Actually, I think one could put the gear leg in a receiver hitch and use a cheater pipe to apply the force. Not as precision as the shop press but it may work just fine.

    Subject: covering & ink issue
    Just a word to all builders about making sure you get any and ALL marking pen ink off before you cover. This is stressed over and over in both the builder's manual and the Poly Fiber manual. I worked and worked on it and thought I had it all cleaned off. I made two complete trips around each side of each wing after I could no longer detect any dirt on a paper towel soaked in lacquer thinner. Only today when I rolled the wing over to finish the tapes on the underside, did I notice ink bleeding through from under the false ribs all along the leading edge! All of the steps I took and not a bit of this showed up until I was using the Poly-Brush to glue down the finishing tapes. :( Kind of heart sick about it, as I was planning (even bought the paint already) on having lemon yellow wings. I know this will bleed through that and be ugly as sin. I know my workmanship is not very good, but this makes it look much worse than it is. And of course, I did not find out until after both wings are covered. My backup plan (now) is to re-design my paint scheme so as to have a black leading edge. This may not work out too bad, as I had planned on using some black anyway. MORRAL OF THE STORY: Get some carb cleaner or brake cleaner in spray cans and blast the heck out of all the rib connection points and anywhere else it may look like there might be magic marker or ink that you cannot get to with a rag. A few $$ spent on a spray cleaner will save you a lot of problems. All the parts that are not covered already are going to get an extra blast cleaning before I do any other wipe down with lacquer thinner prior to covering. Stuart PS Any other ideas on how to stop the bleed through?

    I'd pay particular attention to Larry's advice on the 2x4's. Scratches/dents on any highly stressed structure are bad, and if you nick a gear leg while straightening, the next less than ideal landing (or even some good landing sometime in the future) might result in the remaining stub of leg digging into the runway.

    Subject: Radio antenna question
    From: "Richard Pike" <richard@bcchapel.org>
    For several years we had receive problems with radio coms on the FSII N582EF, transmit was ok, but receive was terrible, could not hear squat. Discovered putting the antenna on the vertical fin was great, solved all sorts of problems. Since it worked so good on that airplane, I tried it on the MKIII N420P and test flew it today. Reception was wonderful, ATC sounded better than they ever have before. Unfortunately, they could not understand anything I said. I was totally unreadable. Since I am electronically challenged, do any of you guys who understand this stuff better than me have any suggestions as to why this might be? I am using a Terra TPX 720 that has always worked well in the previous setup (antenna location here on the belly: http://www.bcchapel.org/pages/0003/pg9.htm ) And it was Ok before, and I can put it back like it was, but any of you guys have any ideas of why it did this? Or suggestions to try next? For context: used new coax, used the same antenna, but straightened, extended straight up from atop the front side of the vertical fin, slightly ahead of the brace wires and rear vertical fin tube. Do not know if the antenna mount is grounded to the airframe. Is that necessary? Aside from that, no other changes from the previous setup.

    Subject: Re: Radio antenna question
    Hi Richard, First, yes, the mount for the antenna should definitely be grounded to the frame, which will then act as the needed counterpoise. (It affects signal strength) Except, I don't think that will solve your problem. If ATC can hear you, but you are unintelligible, I would suspect some problem with the microphone cabling, like RF feedback into the phone wiring. I would suggest to find a buddy with a handheld transceiver, and see how it operates on the ground, starting with engine off. If there are problems already, check all the sensitive cabling like the phone input has its shielding properly grounded. This is not a real easy problem to find and various experiments may be needed, like keying up the transmitter with the Mike not connected, etc, etc. Let us know the results and if the problem is still in existence, the kind of noise /distortion/ interference/ motorboating is heard at the receiving end.

I am using a Terra TPX 720 that has always worked well in the previous setup (antenna location here on the belly: http://www.bcchapel.org/pages/0003/pg9.htm ) And it was Ok before, and I can put it back like it was, but any of you guys have any ideas of why it did this? Or suggestions to try next? For context: used new coax, used the same antenna, but straightened, extended straight up from atop the front side of the vertical fin, slightly ahead of the brace wires and rear vertical fin tube. Do not know if the antenna mount is grounded to the airframe. Is that necessary? Aside from that, no other changes from the previous setup.

    Subject: Re: Bent gear leg question...
    From: Richard Girard <aslsa.rng@gmail.com>
    If you have a bolt on axle fitting, the gear leg is 7075-T6 aluminum. If the gear leg an the axle fitting are welded the gear leg is normalized 4130 steel. Since it's bent it's unlikely that someone followed Hauck's advice and had it heat treated, and since you say it is silver, it's most likely aluminum. My friendship with Mr Hydraulic Press is pretty well documented in the archives so I'll give you the same advice Travis gave me. Wait until you stop bending gear legs and then switch from aluminum to steel because gear legs are a whole lot cheaper than fuselage weldments.

    Subject: Re: covering & ink issue
    From: Richard Girard <aslsa.rng@gmail.com>
    Design a graphic for you leading edge and use Aerothane. You'll lose the easy repairability of Poly Tone, but since Aerothane is a catalyzed urethane paint and doesn't have the MEK solvent mixture in it it will encapsulate the ink. Should that fail, you can always get vinyl graphic overlays like the NASCAR teams do and cover it up that way.

    Subject: Re: Bent gear leg question..
    From: Richard Girard <aslsa.rng@gmail.com>
    Ditto on all the advice about avoiding nicks or scratches. I cut short lengths of plastic pipe and slipped them over the leg so that the vee blocks and the cylinder post cannot damage the leg. Trying to hold gear leg with one hand, pump the hydraulic cylinder with the other and keep flat blocks from slipping off at the same time will make you crazy. Get the 20 ton press.

    I can't remember where I found these pictures but it looks like this would work very well to me.
