Haven't worked on the MarkIII for several years it's stored in the barn but just bought a Firestar II and learning to fly it. Flies a bit different than my old Minimax. Not as snappy on the roll axis. Visability is super and takeoff is hoot. I'm still in the same place Columbiaville and retired now. Stop in sometime for coffee heh? Good to hear from you also.

Might be a little too tight going around but not to the point it is grinding metal. The motor mounts are the ones supplied by the Kolb Factory with the 912. Took the 582 ones off.

Been over a hundred a couple of times at only about 5400 rpm. my set up and aproach is around 70 indicated with touch down somewhere around high 40s I think. at 60 you are still pretty much flying although you have a sink rate. My normal roll out is somewhere between 200 to 300 feet, close to take-off roll. Once the feet are down, speed is lost very fast so there is not a lot of roll out.

Currently it takes a lot of right rudder to roll out straight on take off. If I have a left to right crosswind, it takes full hard right rudder to maintain a straight track. If I have a right to left crosswind, very little rudder is required to keep her straight. My engine is offset slightly to the left right now. I have about 3.75" from the prop to the aileron tube on the pilot's left side, and about 4.75" on the right. Is this set up helping the situation or making it worse? It seems to me since the engine is behind the CG, it would make it worse. My prop turns counter-clockwise looking at it from behind the airplane. I do have a rudder tab on the left side, and the plane flys straight & level with very little stick input once up. Any thoughts on this?

That sounds like about the same performance envelope as my titan - 95mph cruise, 60mph on final, TD about 40 with full flaps. Have you tried a different prop type? My next attempt is going to be a powerfin F model which judging by my spare 68" that I have left over from my 2-stroke days, has a very different resonance to the blades than the WD. Doubt it'll have the same speed range as the WD but it may run smoother. It's worth a shot anyway especially if it runs smoother.

My FSII required a lot of left rudder on the takeoff roll (mine had the 503 with the prop turning right-hand, swinging the big ol 68" WD 3 blade on a 3.47 C box) but didn't have a lot of torque problems in the air. Mine also didn't have any offset in the mount, but I should think that would help. Perhaps not. I mitigated the problem by just applying power slower especially if there was a crosswind so the torque wouldn't overcome the rudder. By the time the tail came up I could go to wide open without having to hold as much left rudder pressure. Soft-field takeoffs where I held the tail down longer with back pressure on the stick, tho, would still require the hefty left rudder until I got to flying speed.....

I have the Obrien hydraulic brakes, they are wonderful reliable, I have not had to touch them in over 2 years, they would be perfect on a lighter plane like a firestar, but I just need more stopping power... I could not induce a nose over with the brakes even if I tried. There have been a couple times with long taxiing on pavement that I have overheated them and had them fade completely.

Fatigue, however, due to the increased thrumming I already know is an issue tho I may eventually get used to that too. >> Lucien - Although you've heard my story about fatigue failures already, I think it bears repeating, for the benefit of those on this Kolb List who might also benefit. I experienced a similar harmonic problem in the first year I began flying my Kolb. I built my plane with a Verner engine (made in the Czech Republic - a 1400cc air cooled, 80 hp, twin cylinder boxer engine). Like you are experiencing, I too was getting some sort of harmonic whose source I could not identify. Engine ran smooth, blades tracked exactly, no severe vibration. But consistently, after every 6 hours of operation, I was discovering BROKEN PROP BOLTS on my post-flight inspection! Could not pinpoint specifically where the harmonic was originating - was most likely just my particular airframe/engine/prop combination. I did not want to begin experimenting with different propellers to see if that would solve my problem. Bottom line for me was, after three times of discovering broken prop bolts, I finally ditched the Verner and bought a used 912 to replace it. I never discovered what was causing the bolts to break. But I am happy with my 912 - have not had any reoccurrence of the damaging harmonic. And so my advice would be: Don't ignore those harmonics - you don't wanna just "get used" to it! Good for you (and you too, Ted C.), for your tenacious efforts in trying to discover and eliminate the source of your harmonic thrumming! Eventually, those low-frequency harmonics will take their toll on some part of your airplane which could result is something else failing. As my experience shows, these things do happen. Good luck in finding your gremlin(s) ...

You probably would need a spool gun which has a small roll of aluminum right on the welding gun. Don't know if they make a spool gun for your welder or not.

BTW, that 100mph cruise is at only 5050 to 5090 rpm and slightly more than half throttle, which is simply spectacular performance. I couldn't get 100mph indicated with the IVO at those rpms no matter how I had it set. I'm still shocked and amazed even tho I landed a couple hours ago...

I did find that it was a good remedy for Bat shit on your wings though. During recovering and subsequent painting of my plane, I could hear the Bats in the rafters squealing and raising hell. That has been two years and have not had a speck of guano since. Mosquitoes are worse though.
