Thanks again, Paul. Red confirmed that his laser is perfectly happy to cut Bluecor.
The Twin is on my son's short list!

OK guys, get the word out... how many sheets of bluecor do you need? I can bring them to the field on Sunday if you like.

Paul, I have templates to cut the "twin" out, let me know and you can have them. I printed them tiled and then secured them to thin cardboard before cutting them out. They fit fine, the build went well, just need some CF rod for the wings instead of the spruce spars they recommend.

BTW, the "twin" flies better than they show in the video, it's really a hoot. Your son will like it. Paul

Paul, you rock! Drew is stoked about the templates. He really doesn't like tiling the drawings and cutting the paper. Not sure why that is such an obstacle for him.
Ok, from what I understand the Polaris lineup is like so:
1 Paul Kohlmann
1 Drew Kohlmann
1 Red Jensen
1 Jeff Penner
2 Steve Koll
1 Dave Mercer
1 Paul Eason
So far, that puts us at 8 kits but there is still time to add more. We can easily get one Polaris per sheet of Bluecor. Right now the cut file is set up for Depron sheet size, so if a builder prefers Depron that's fine but he'll need to get that material. Drew and I would like to take Paul up on his offer for Bluecor.

Tiling isn't hard, I use a program called "scale and tile" that I downloaded for free from it's author on RC Groups (William Segraves). Works well. Not clear if this program is still available.
Let me know how many you guys want and I'll bring the bluecor to the club Sunday if you'll be around. I'll bring some extra sheets so Red can do some test cuts.

LOL--I never said that tiling was hard. Just that my 11y old hates putting the drawing back together and cutting out all of the pieces. Must be a haunting kindergarten memory in there somewhere.
Morning MigRaptor.

Paul, I knew it was your son that thought it was hard. I'll give him the templates and enough bluecor to make a Twin, he's just got to finish it and fly it this year! Tell him that's the deal. Paul

Ok, Paul. I told Drew the terms of the offer and he has accepted the challenge.
He says thanks!

Paul, do the plans you gave to Red have the updated nacelle as shown in topic 392 on the RC Groups thread? This would simplify the build. Wow, 1000+ posts, there's a lot there... I'm digging through them to see if there are other critical items we should discuss.

To be honest I didn't go through the 1500 posts. Wow is right! I converted the earlier drawing. The mod isn't a big change, though. I'm going to let it ride--day job is cutting into my modeling time  Paul |

Should be fine, I'm looking forward to starting the build. Wiley suggested we look carefuly at the cooling issues with the ESC burried in the airframe. I have an idea on how to solve this. I've got some pin-fin heatsinks that have super long fins on them. Given that this bird requires a 30A ESC, these sinks would be fine (replacing the stock flat heatsink on the ESC) and could push through the top of the fuse to allow cooling and still provide a water-tight fuse (once you see them you'll understand what I'm saying). I'll experiment on a HK 30A ESC that I have and see if it works. If so, I've got a bunch of them from an old project at work and will hand them out to the builders if you guys want some.

Great minds, Paul. I understand completely what you are getting at. I think its a good idea. Attached is a Polaris with the same scheme. Don't hold it against the guy that he put the US insignia on upside down. Drew and I run the same 30A setup in our T38's. The fuse is open from the inlets to the jet nozzles on those so heat isn't a problem. I'm pretty sure that the Talons would go China Syndrome if the flow stopped, though. Its just too much fun firewalling those things. Paul |

This is what the sinks look like (kinda sorta). Heat one up and push it through the foam.
