gharm -> Lanier 1/3 scale Laser 200 cg and thrust angle (1/30/2005 2:43 AM) I just got a slightly used Lanier 1/3 scale Laser 200 (from a kit). It will be getting a ZDZ 80 with a canister muffler. Can anyone tell me the cg location and the engine thrust offset angle? I downloaded the manual from Lanier, but it says refer to the plans for the cg and I do not have plans. Thanks George Harm

z4cr33v35 -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (1/30/2005 4:15 AM) on my plans, it doesnt say anything about the angle, and just shows the cg as the center of the wingspar, not sure im any help but if you need anything else from there, the plans are on my wall

gharm -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (1/30/2005 12:16 PM) Thank you. I was guessing that the usual 2 degrees right thrust would be a good starting place

spitcurl -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (2/1/2005 11:45 PM) Gharm. I'm new at this. I haven't a clue as to why an engine would be alligned offset. Is This because the prop is rotating down on the right of centerline and up on the left side of center? Educate me please.

sensei -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (2/2/2005 12:23 PM) The C/G location is the center of the wing tube, and the thrust angle should be 0 degrees up and down with 2 degrees right angle.[;)] Bob Sawyer

gharm -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (2/3/2005 3:03 AM) Thrust angle requirements can be a very long discussion. In the end, however, it is the particular airplane that will tell you what is needed -- if you are listening to the airplane. In general, a little right thrust tends to be needed to keep the plane flying in a straight line with the application of power. Some airplanes also like a little upthrust or downthrust, too. In this case I was trying to find the recommended starting point that was determined by the kit manufacturer who, I presume, found out what the aircraft needed during development. This is just a starting point and trimming is required to set the airplane up to my flying preferences. In other words, try trim changes and see if you like what happens. I do not have a quick reference guide handy, but a web search should find plenty of information on trimming procedures George

sensei -> RE: Lanier 1/3 scale Laser 200 cg and thrust angle (2/3/2005 12:52 PM) If the Laser is built strait, and the angle of incident on of the wing and horizontal stab have been set at 0 degrees per the drawing, than the set-up I spoke of in my earlier post works very neutral on this platform.
