Denny, when just get home I'll measure the ones on the plans. Thanks
Bill, see how that cowl has a wider opening. That gp cowl looks like the cowl on the radial rocket.
On a side note, of you do not have forstner bits, a 9mm casing with the edges sharpened will make a nice servo lead hole without fraying the wood. Also fit right into the chuck of the drill.
