Hey jim i just got the controller working today for my cnc foam cutter the rest should be up and running in a couple of weeks was just wondering how much you plans are worth. $100 to cut foam thats crazy my whole cutter is costing me under $100 cdn. and a bottle of scotch (but not the good stuff)

Thanks
Tom

Any plans for this cutter?? Probably would cost me less as I can't tell the difference between good and bad scotch

I just did the initial leg work, because dorysch1 said he didn't have a foam cutter. I have a home made "feather cut" and published an article in MA a few years back. I would rather do the work myself, but in this age of ARFs, some may want to just buy the cores.

If you're interested in the plan, send me a PM.

I prefer to buy not so much arfs but mostly built kits because I don't really have a ton of liesure time with two jobs I wish I did have the time but if I get time I like to use it flying don't forget a guy pays a hundred dollars for a twinstar not that it's bad but a b-29 looks very nice in the air

Here's the latest picture of my progress. Progress has slowed due to everyone in the house being sick but me.

The wing mounts are in place and the wing saddle is cleaned up. The mounting blocks were inserted through one side of the fuse and patched after the glue set up. By keeping the 1/32" reinforcment plates tight to the mounts, they held themselves in place while the epoxy cured.

I've started installing the servos and I have the elevator linkage setup for internal control. I'm going to cover the tail feathers before attaching them to the fuse.

Total weight is 28oz with motors and airframe. Target weight is 64 oz. with an 8x2400 pack for a wing loading of just 16oz/ft^2.

Thanks for the kind words, guys. It's really fallen together in a short amount of time.

The current snag is one of the aileron servo leads. I was installing the aileron servos Wednesday night and one works fine, but the other.... nothing! I have a home built servo-ciscer and when I connect it to the servo, everything is fine. When it is connected through the lead burried in the wing, nothing. I'm hoping that it is just one of the connector pins that is bad. I'd hate to have to tear the lead out of the wing because it's cut somewhere

The good news is that when I was cutting holes for the aileron servos, the bond I got between the balsa and foam was great. It took some real effort to peal the balsa off of the foam. This vacuum bagging thing works great.

Here is the latest set of pictures...

The tail is covered and I've added panel lines and rivet detail. I just used the back of a #11 blade to scribe the lines and a "dress maker's" wheel to add the rivets. This is less than 1/2 an hour worth of work. The wing is covered and I'm waiting on the LHS to get more chrome Ultracote in to finish the fuse.

P.S. I got a little too agressive cutting out the aileron mounts, and cut through the servo lead. I just had to cut into the wing sheeting about 1/2 inch and solder it back together.
