That sounds about right. Especially if youre running a Ivoprop, because of the blade flex. Sent from my iPhone > On Jul 8, 2020, at 9:51 PM, John Fitt wrote: > > > I have a firestar 2. In order to correctly calculate the weight and balance for my plane- step 1 is to cause the wing to be at 9 degrees (7 1/2) by raising the tail. Simulate the scales thickness with a similar block under all wheels if you only have one scale... the plane must remain at the 9 degree wing angle throughout the weighing. The block is removed when each individual wheel is weighed. > My plane required that I was in the pilots seat to put the CG within the allowable range. After talking with Brian at Kolb I suggested that maybe I could move the engine forward 1. He said that I should then install a 1 spacer to move the prop backwards to its original clearance from the wing. > > > John Fitt > >> On Jul 8, 2020, at 12:46 PM, Steve Sands wrote: >> >> >> I am working on an older Mk3 that has never flown.

It all depends on wing incidence. You don't want the engine thrust pushing you down and the wing is more efficient at producing lift than engine thrust so set the engine to point straight back in flight. Also not right or left. So the answer is no don't set the engine thrust even with the fuselage boom or the horizontal stabilizer. Set the engine thrust even with the bottom of the wing plus a few degrees for the wing to produce lift. Watching Kolbs fly I see some flying close to boom tube level but most flying tail high. We had one on the list that must have built his MKIII to fly way tail high so the fuselage tube is a poor reference. The horizontal stabilizer frequently gets adjusted after a few flights for pitch stability. Remember the horizontal stabilizer's function is to push the tail down and then stabilize pitch. As usual, worth what you paid. Rick Neilsen Redrive VW Powered MKIIIC On Wed, Jul 8, 2020 at 3:49 PM Steve Sands wrote: > > I am working on an older Mk3 that has never flown.

From: "esp3500" Thanks guys. If nothing else you have been great at putting thing into perspective for me. Yes, grass runways are 90% of the runways around here and the couple of paved ones are not on my list of places I want to go, so I don't see a paved runway anywhere in my near future. I will be doing quite a lot of taxiing before this kolb goes up because I am the one that restored it, and even though I was very very cautious and I think thorough, I still want some ground hours to see it is safe.

Ok one more thing. Be very careful not to taxi up to takeoff speed if you're not ready to fly. If you get to that point and chop the power you will find yourself airborne and climbing with little flying speed, add power and you will be nose down with reduced elevator power. Also crow hopps don't end well with high thrust line pusher airplanes. Repeat after me add power pull back on stick, reduce power push on stick. As usual, with what you paid for it.
