I have used the Concorde battery since 1994 and really like it. They do not have gelled electrolyte in them. The acid is in very fine glass fiber surounding each plate which is all sealed in a plastic sac. If the case breaks open there is no acid leak. One of the best features is I have not had to r...

The ignition wires on my plane were looking old when I bought it in 1987. Radio noise has been getting worse. And I have been wondering if a bigger mag drop on the left mag could be helped with new wires. The wires to the lower plugs are too long and are all doubled up and tie-wrapped together so I ...

Your U bolt problem reminded me of my trip to Alaska in 1994. We left Oshkosh late in the day and got to St. Cloud MN about dark. On landing, I could tell there was something bad wrong with the tailwheel. :evil: The U bolt was broken. Of course the next morning there was no way to get one to go on t...

Rudy, If my plane is fast, I am really surprised. It was wrecked when it was 6 months old and that repair, while structurally OK, was not done with great care to maintain original contours. That really came to light when I installed a baggage door. Because of the less than perfect repair, I could no...

I was interested in obtaining some baseline data on the speed of my plane to check the effect of various modifications. Full power runs are about the only way to avoid errors is setting the power. The best tool for this that I have found is a program that uses GPS or Loran speed data from three cons...

I read your original post again and I remembered another similar problem I had. It was an intake leak. one of the intake rubbers was simply pushed against the metal-not over it. After about 200 hrs. it began to run rough similar to your problem. I simply stumbled on to it after trying everything els...

I have a couple of questions regarding the C170B, specifically S/N 26126 a 1954 bird. 1. What is the prop clearance in level flight attitude? Where is that listed in the specifications? 2. What is the FAA required prop clearance for a taildragger? Where is that to be found? I figure it must be in Pa...

My control wheels are attached with appropriately sized roll pins cut flush. Then a stainless steel 6-32 screw with washers on each end and a fiber lock nut runs through the roll pin to trap it. Better than new, probably heavier but a lot cheaper than new Cessna parts.

BIG CAUTION HERE. I had this problem about 12 years ago and it went on for about 60 hours before the cylinder cracked enough that the piston caught it and pushed the whole top of the cylinder off. The cylinder base and about one inch of the steel barrel stayed bolted to the case. That saved the case...

Are you running on auto fuel? If so, it tends to fowl the plugs at idle. It is worse with the one piece venturi. I lean it until it gets rough and then go back rich until smooth while it warms up on the ground. You can't hurt it by leaning at low power settings while taxiing etc. I keep it so lean t...

All the comments about washing, removing frost or wing covers are valid questions and the VGs make them more difficult. My strip is a 910 feet elevation but the engine is getting tired and I am about to assemble a new one. Maybe that will make my performance better. I have been thinking about why th...

Micro Vortex generator Kit for Cessna 170B by Gary Collins I have owned my 1954 Cessna 170B since 1987. The 170 is a relatively big airplane that does a remarkable job on just 145 hp. I soon learned that at near gross weight and if it is hot, you have to be careful on the shorter strips I like to us...

N1981C is a relatively standard 1954 Cessna 170B with the standard C-145-2 engine, 7653 prop, 1200 SMOH, original wheel pants. I have the Horizon Instruments electronic tach so I am sure my rpm readings are accurate. I regularly fly by manifold pressure using 23.5 inches at low altitudes which gives...
