So I just removed the prop each time. Socket in electric drill and torque wrench handy only took a couple of minutes each time. Maybe you could consider a 4-blade used that way.... I did that for quite awhile until I could find a B-box. With 2.58 ratio and two-blade prop it went better but more vibration and noise.... Have you done a good 4-way GPS run to check the ASI?? GPS readings don't have any real value unless you do a complete 360 circuit on a steady day..... ________________________________ Message 2 _____________________________________ Time: 10:24:29 AM PST US Subject: Kolb-List: Re: HKS / Firestar FLIGHT TEST resumes From: "racerjerry" Bill, have you verified ignition timing is correct? That could explain a lot of things. Also, you were concerned about getting your Firestar up on its nose. The Firestar's main wheels are located well reward as compared to most other taildraggers. I believe this makes the airplane less twitchy; however it can nose over more easily. BUT, the only times I had this happen is when getting stuck in tall grass or mud and trying to power out using the engine to unstick. For lazy people like me nose bowls and nose art are temporary expendable items.

Do you still have your extended exhaust pipes and exhaust under the boom. Maybe that is creating alot of drag to slow you down. It sounds like your engine is running well so the exhaust may be working well and not robbing power, but the added tubes and stuff out in the airstream must be a drag source. Maybe you can take the exhaust off for a test (No cost, just very noisy). Also, your alignment of wings and Horizontal Stab is working, you have proved that. One thing you did not confirm is the angle of the boom tube to the ground in flying position. IF that was wrong and set too high at the tail, your angles of wings and Horz will have to be adjusted to offset this boom angle. And this is exactly how you have rigged your plane. You have assumed the boom was set correctly at the factory but maybe something is off and this is an incorrect assumption. These are thoughts about your situation and as stated before worth what ya paid for it.

No adjustment, no possibility of errors. My aircraft has significantly longer gear legs than any other Firestar. So because of the mounting angle, this puts the wheels a little further forward than they wouuldotherwise be. It is controllable for someone with previous taildragger experience, but probably not as easy and gentle as the stock Kolb.

FrankD ________________________________ Message 6 _____________________________________ Time: 03:34:13 PM PST US From: Eugene Zimmerman Subject: Re: Kolb-List: HKS / Firestar FLIGHT TEST resumes Bill, I have a 670 Rotax Rick engine with a 4/1 ratio C box on a Mark 3 Classic. It has a 3 blade 64=9D Ivo MEDIUM prop. I have derated my 670 by lowering the compression ratio to produce no more than 80hp @ 6500 rpm. 6500rpm divided by 4 gives me 1625 prop rpm on climb out. I cruise easy @ 4500-5200 engine rpm, 1125-1300 prop rpm @ 55-65 MPH I believe you could get optimum performance from your engine and gear box with an IVO medium prop. > On Nov 19, 2018, at 8:05 PM, Bill Berle wrote: > > I do not have an Ivoprop, I have an Arplast prop from France. I need the Arplast because I need a large blade area (wide chord) to absorb 58HP within a diameter and RPM restriction. I have a 3.47 to 1 gearbox on the engine. The prop RPM is so slow that I need all the area I can get to absorb that power. If I had the 2.58 gearbox I would be able to turn a 64 inch Ivo or Warp Drive prop at higher RPM like most Kolbs. ________________________________ Message 7 _____________________________________ Time: 04:12:04 PM PST US Subject: Kolb-List: Re: My Firestar 2 Build From: "haybail" I just started to rebuild my barn find FS2 and the original plans show FS100 also, You may need to sand the end of the tube lightly to bring up numbers mine is marked F1002 with the latest revision 1993. I have been in touch with Kolb and they are going to see if they have records from that time period. If there numbering is as most manufacturers use the "F" is the model The "1" is a control number and the last three Or four would designate build number. I could be completely WRONG!
