GET the LEAD OUT !
I am assembling a Lanier 120 size, 540T Edge for a guy in our club. He supplied an OS 160 FX motor, elevator servos are in the tail, and the battery is WAY up front, flat againest the back of firewall. The CG is stated at 4 to 4 3/4" back from leading edge at fuse. I want a "mild 4 1/4" for this pilot as a start point. THIS THING is tail heavy!!! I want to bolt the weight to the front of firewall, but early test weights showed it needs about ONE POUND OF LEAD !!! [
] Anyone else out there with this same plane and CG situation? Is this possible? Thanks in advance..........lownslo.

yes take the servos out and put them under the wing it should have a piece of paper in the box saying that if a glow engine is used the servos go under the wing tail servo mounts are for 40cc gas

RE: GET the LEAD OUT !
OH MAN !! What a bummer. This fellow bought the plane at a swap meet, some things assembled. The servo bays in the tail already had the covering cut out. I have edited this reply because I looked at the instructions again and there was mention of a "light engine".
Using the one front mounted servo, and the proposed control rod they showed, was not going to be what I would want on a plane and engine of this size, so I went with the tail servos. To me.... the guy selling the plane was not being straight with some information. He said he has had 4 of these ARF's and has had OS 160's on all. The firewall had 8 holes in it for 2 different motor mounts ? and a BIG part of the firewall cut away.... for muffler clearance I guess. I added ply to front and back of firewall to make it sturdy again. The thing is.... the cowl was cut for something other than an OS 160. One good thing is he has plenty of power with the 1.60. ... Thanks... lownslo.

the push rod is fine i use it on a cap 232, edge 540 and extra 230 all around the same size as the lanier and have flown the lanier on the push rod set up as long as the push rod is still enough it will be fine wit ha pound of weight on the nose it flies like you left the wing off
