Gents,

is there someone who might have a copy of the plans that come with the GP Illusion? Id' be grateful for some snaps if possible. I'm primarily interested in knowing the distance of the stab and wing center lines compared to the thrust line. My understanding is that the Illusion is not much different than the Tiporare other than reduced stab anhedral and a wing located closer to the thrust line. The called for stab anhedral would also be helpful. I'm going to guess 2" total.

Attached are some pictures I found on another RCU thread for reference. Mmm... it looks like the wing top's highest point is located ON the thrust line.

Many thanks, David.

For those interested, I have since confirmed that the wing and stab center lines on the Illusion are equidistant from the the thrust line. This became a common trend in later classic pattern designs with several models with such a configuration (or approximately so). These designs include the Deception (perhaps one of the earliest and designed specifically around this concept), Illusion, Escape, XLT, Aurora, Atlanta, Beetle and others.

I should have specific measurements on the wing airfoil thickness of the Illusion later this year but from all evidence, the wing and stab airfoils (and planforms) are identical to those of the Tipo. As for wing dihedral and stab anhedral, the kit documentation confirms that the wing is joined upside down with a 1/16" gap at the root (i.e., practically flat top) and the stab anhedral is 2" total.

For any scratch Illusion builders out there, I hope this helps.

David.
