It is bent to the right thus pushing the rudder to the left (if you are looking at the plane from the rear). My Kolb was built by Brian Milburn, who I believe most would agree has a stellar reputation for building quality Kolb aircraft. If you need rudder deflection to the left, to me it makes most sense to have the tab on the right side of the rudder, thus "pushing" the rudder to the left, spreading most of the load along the trim tab itself. With the tab attached to the left side of the rudder the tab would actually be "pulling" the rudder to the left and placing most of the load against the attach rivets. But then again, the load amounts might be so small that this is not an issue. My guess is that the key point is to attach the tab to the side of the rudder opposite the trailing edge tube. I do have a Kolb Trim Tab document dated 10-96 that does show the tab attached to the left side of the rudder bent to the right. But in this drawing, the trailing edge tube is on the right side of the ribs, thus making the best installation point the left side. My plane the trailing edge tube is on the left side of the ribs, so the tab is best mounted on the right. Well thats just my .02 worth, and in this case, you are probably not even getting your monies worth! :-) Mike S Manchester TN Firestar 2 503 do not archive DAquaNut@aol.com wrote: --> Kolb-List message posted by: DAquaNut@aol.com Group, I am left with no choice but to put a trim tab on my rudder. Problem is the factory put the ribs on the right side of the rudder as viewed from the rear. I need to make the rudder move to the left substantially . That would involve putting the 2" portion of the trim tab on the left side of the rudder while the 3" portion which is roughly 30* would be on the right side in order to push the rudder to the left. There is not a rib on the left side to put the rivets in. Is it OK to mount the entire trim tab on the right side where the ribs are. I will have to put the rivets on the right side instead of how Kolb shows it. Hope I am making sense . I just dont think I have seen a trim tab mounted on the same side as the angled part.

The only reason I know of the existence of the bubbles is that I went looking for the cause of the fuel alarm.

Trim tabs to be optimized usually need to be fine tuned by the very smallest bend. Lexan is springy and I'm afraid you will be making an awful lot of flights to get the minute adjustment needed. Thin aluminum works best for me.

The bubbles pose no problem to me, in that they do not affect my engines performance. Bing took care of the problem by providing a system to seperate the air from the fuel before it enters the main jet well. Nope.........I didn't say or intend that the bubbles were not there if I could not see them. ;-) Did not say the plastic line was porous. Have no experimental data to back up what I said. I do have the experience with my engines and fuel systems though, to more than adequately back it up. Nope, don't get the drift. Not looking for it.

My fuel level is 30 + inches below the fuel pump at times and my fuel pressure stays very constant. I also use EIS to monitor fuel pressure and have never had it to alarm with the engine running. Is your tank properly vented? Do you have a fuel filter on the suction side of the pump and if so is it located down at the tank or close to the pump? How often does it alarm? Any kinks or callapsed hose on the suction side?

I had my radiator in that location for a while, finally decided it was acting too much like a spoiler - Biggest problem was if I got up to operating temps and couldn't go ahead and take off, it overheated. Because it was too far from the prop, no airflow. But your radiator looks bigger than the one I had - comments? How much does the electric flap actuator weigh?

" Yes. I measured 2 inches of water pressure on a manometer taped into the fuel tank vents during level flight. "Do you have a fuel filter on the suction side of the pump and if so is it located down at the tank or close to the pump?" Yes I normally have a fuel filter in the sentiment bowl. However, I removed it for the testing. So it would not impact the observations. "How often does it alarm?" The alarms seem to increase as the fuel level in the tank goes down. The alarms first occur at about 10.9 gal out of 13.4 gal at the start of the flight. The alarm flashed so fast I couldn't see what the parameter was. Later (about 30 min.) the alarm stayed on long enough to identify it as the fuel pressure. Later still (about 35 min) it stayed on long enough for me to watch the fuel pressure fluctuate between 0 and 2 and back to 0 pounds of pressure. I headed back to the airport then. The alarm was flashing randomly and frequently a couple of times a minuite. There was about 8.5 gal of fuel in the tanks. The tanks are in the wing roots. All my testing was done on the ground with the remaining fuel in the tanks. The alarming was frequent enough that I turned on an auxiliary electric fuel pump when I entered the pattern. The alarms stopped. The fuel pressure no longer fluctuated around 4 to 5 psi but stabilized at 5 psi. The electric pump is about 4 inched from the sentiment bowl at the same level. " Any kinks or collapsed hose on the suction side?" I inspected for this, however, the fire protection covering over the neoprene hoses makes this hard to determine. In view of the last question and the electric fuel pump action, this could be a problem area. Tomorrow I will determine the adequacy of the hoses to the engine!

It may warm up a bit over operating temp in a prolonged idle. I do not worry about it until temps get over 180. Temps are 140 +/- while flying. I'll block off part of the radiator in colder weather. I wanted to keep radiator and exhaust weight in front of the engine so I could mount the engine as far aft as possible for maximum prop clearance from torque tubes. I used an aluminum auto radiator from a Ford Fiesta. It fits nicely between the wings and slants front to keep the height to a minimum and provide room for a standard rotax exhaust system. The electric servo is very light, I would guess less than 1lb. I will post an exact weight for you this coming week.

I salvaged several from a bunch of stuff they were discarding. They were slightly used but like new. I believe you can get them from an industrial supply place like Grainger but they may be a little salty. I could check for you. I'll also post an exact weight but they are very light. I did not time the full stroke but they are very similar to speed of 152/172 Cessna flaps, perhaps a bit faster. The plastic angle is a corner wall protector strip you can get in the Paint and Wall Paper section of a Home Depot or most any homebuilder supply place. They come in 8 lengths with stick on adhesive for only a coupla bucks. Of course the adhesive is on the wrong side for our use. I simply removed the tape, cut them to little inch and a quarter pieces, put them all in a jar with gasoline for an hour or two to dissolve the sticky adhesive then wiped them clean with a towel and cut the angle with a scissors. Make half of them left and half of them right. Stick em on with a dab of clear RTV silicone. Cost ya less then 10 bucks. As far as the wing tip mods, I have had several Kolb models with the standard wing tip. It is rather tedious to get the compound bend on the bow tube just right to do the tip modification. The difference in handling is that the mod now gives some definite roll control with rudder only which the standard Kolb tip configuration does not provide. All standard Kolb models are roll unstable with rudder control only. I like the looks of it and the roll control but would I encourage others to try the mod? Probably not. The flaps and the VGs are what make me a happy camper with my Firestar mods.

I bought my Firestar used and eventually recovered the fuselage cage due to some fabric damage at the bottom of the fuselage. When I did the recover I decided to powder coat the tubular cage. After the work was completed, I found out that the heat of the powder coating process must have relaxed the fuselage cage stresses built into the cage during its construction. During the first test flight I found I had a wing heavy condition of the right side that I didnt have before. The English U joints allowed me to reset the incidence of the light side to match the wings together again. I blocked up the Firestar into a level flight attitude. By moving the supplied washers from top to bottom,one at a time, I was able to match the two wings again using a long level across the bottom of each wing until the bubble matched side to side. I bought a pair of the U Joints just in case I needed alot of adjustment but I ended up only using one on the left wing. I hope this helps answer your questions about the English U Joints. The joints allow me to zero out my wing trim and avoid speed eating drag due to aileron trim deflection.
