Nice site - and the business is for sale.
I am thinking of converting one of these
to RC like the do with the foam profile planes.
Re: Ace cores - I was digging around in my garage and found a stash of 2 straight and one tapered cores NIB. $2.95 price tag on them, still sealed with tape like I got them some 20 years ago ( and no, they aren't for sale. I've got some nostalgia projects ).
I can't believe I am excited about the thought of castor oil and glow plugs again. I may even do some control line again - there is a local club with a nice CL only field. I am on the hunt for some nitro motors and planes from my youth. Like a ringmaster ant K&B Torpedo 35, a Super Tigre G21 .35 in a Voodo combat wing with a baby pacifier tank and 8 x 8 or 9 x 7 prop. Veco 19/RC in a Goldberg Falcon 56 ( ok - thats RC, but it was the first RC I had with servos - Orbit 4 ch tube radio - rudder & throttle), Mini-Mambo and a Golden Bee. The thrill of WOT flying.
