Help! 33% Pilot Yak 54 CG?

Discussion in 'Giant / Scale RC General Discussions' started by Raven, Jun 23, 2017.

  1. I have recently aquired a 33% Pilot Yak 54 with a zdz 80. I am curious as the the cg location on this plane. I have yet to fly it but its current cg is sitting just on the forward part of the wing tube. I am looking to do some 3d type stuff with it and think it should be near the backside of the wing tube. Can anyone confirm this as i cannot find a manual anywhere for this particular model

    There should be a CG inside the airplane, if not here is the link for the Pilots generic instructions that have CG's listed for various models. http://pilot-rc.com/Upload/201402190642.pdf

    Should be 183mm from the leading edge for the 87" and 225mm for the 107" if I'm reading it correctly. What's the span on yours?

  3. 97" wingspan. Not listed anywhere on the site. Too old i guess.

    Are you sure it's 97" and not 107" A 33% Yak 54 is technically ~107".
  5. Im sure it is a 97". I have measured wingtip to wingtip. A google search for 33% pilot yak 54 shows it is 97".

    If all else fails, email Tony at Pilot and he can tell you where the CG is.

    Yeah the 33% was for an 85cc. I didn't realize Pilot made one, I knew Aeroworks did.

    Awesome plane. Had one with a 3W 80. Don`t remember how much, but I know I had the CG behind the wing tube.
    Edit; come to think about it.. Mine was a SD Yak 33%. Same plane?

    Not the same plane. Pilot did in fact offer a 33% 97" Yak 54.
    The Predessor to this was indeed the SD 33% 95" Yak 54.

    Can't say for sure but have heard the Pilot was a good flying plane. The SD on the other hand is amazing.

    As for cg? I never checked my SD. I flipped the prop, warmed the 62 and blasted off. What a thrill. But... from all my other Pilot RC airframes, cg is usually on or aft of wing tube centerline. Depending on your flying style. I likes mine neutral to slightly tail heavy.
