Did any one give a reply to Doug Reeve of Johannesburg So.Africaon his question about why his "O200 Piet. has a nasty habit of dropping its tailwheel on before the main wheels,"? And therefor has to"take power and go around-I usually have to wheel land this one." Whereas his otherpiet, a "Geager (sic) with a C90 Wood construction..." would makethree point landings. He said the O200 Piet has 14 deg more up elevator than the "Geager",which makes three pointers. Maybe the horizontal stabilizer on theO200 Piet is stalling due to greater elevator movement.I may have missed the discussion but could the weight and balance be a little far back, maybe at the aft end of safe range.Or maybe the incidence of the horizontal stabilizer and elevator in relation to the wing is not to the drawings, or visa-versa. The wing has a call out of 2 deg incedence in relation to the upper longerons. The horizontal stabilizer is not parallel to the upper longeronbut sits 1/16" higher over 13 1/2" giving 16 minutes of a deg. of incedence.This makes the wing to horizontal stabilizer incedence, on paper, to be1 deg. 44 min. Sounds like Doug should check basic wing incedence first and then if that's ok, put some sort of elevator movement limiter on the O200 Pietand check it out then.But imagine, going out to the aerodrome and having to decide whichone to fly today, maybe both. Ok, then which one first. Naw, couldn't be sour grapes on my part.RodgerPiet in progress________________________________________________________________________________

Thanx to all of you for the replies,I dont know what you are talking about regarding wing positions.I will check out the CG this weekeend and replyWhere should the CG be in relation to the wing leading edge ?Yes it is wonderfull to be able to choose what Piet Im going to fly.My wife has just completed her pilots licence on the Piet sonow I will have to share with her-But I also have a 300hpStarduster that I play with .As far as I know there are 5 Piets flying in South Africawith a 6 th one about to do its maiden flight on SaterdayAlso I know of about 4 others under construction in SAbut very few peaple here fly them mutch.My wife and I intend flying our twoto Namibia in about 2 months time- about 600 miles over the Namib desertshould be fun.If any one wants pix of some of the South african Piets I have Digital pixof4 SA planesRegards DougJohannesburg________________________________________________________________________________
