Another fun day in the gym - flying not exercising. We had a great turnout with a new flyer or two and a familiar summer face trying out the winter passtime. Dan Jr. (Pic 1) brought his home made tricopter. Dan is a whiz on computers and assembled his creation from computer parts he had and parts from a WII machine. It flys well and is scheduled for some refinements in the near future. The Foam Star, Gaston (Pic 2) was caught hovering so he could admire his favorite colour, BLUE Light. He is having the time of his life, and he really is the only 67 yr. old I know that can do rolling circles in a gym. The man is tireless in promoting winter flying fun in the gym and at the field in Summer.

Re: Blue Foamie

You wanna beilieve it! He's the greatest guy I've ever known, and soon, I'll get to see him face to face, hopefully not with a flyin Yak tho... Ho ho..
Looks like he and his buddy have found some newer, lighter lipos and servos, dang nab, gotta go get these now......
Hey, who's gonna break the 3 oz weight????? (How bout some helium in sealable pockets on the airframe??????????????????????)

Re: Blue Foamie

Managed to find time to build my Blue Foamie over the weekend. WOW, that was easy to put together. Very high precision, everything included, simply an awesome kit. Just looking forward to fly it, that's if I can get the propeller to stay on... I use a Turnigy 2204-14T 19g Outrunner and a GWS 8043 propeller which, once I hit full throttle, happily flew across the room, leaving a scar on my airplane before it took off. Sure enough, it's not a perfect fit. Do you guys modify the propeller (add a nut, or fill with epoxy and drill to right size?). Or should I simply use two turns of the rubber band (I did only one) since it's rather loose?

Here's the motor:

Hi
Go to a hardware or automotive store and buy some "o" rings 5/8in. i.d.X 1/16in or 3/32in the rubber band that comes with the motor is useless, the "o" ring will cost you anywhere from $0.08 to $0.60 each.

Thanks Art, soon we'll have to add weight or turn off the ceiling fans at the gym, they're getting very light....

Consider that this entire thread would not exist if it wasn't for Gaston. Does he know how to keep us all busy? Or does he know how to keep us all busy? OH!! Did I ask you does.......

Thanks for the quick answer... I probably have some in stock already. BTW, I have both props (8043 and 8040). For my first flights (maiden), what do you suggest I use?

Did you get a bit of dead throttle with that motor/ESC combo? I've tested it only with a servo tester so far, and I need about 15% throttle before it start spinning. I can probably fix that with my DX7 but I'm curious. I've used many Turnigy motors and ESC in the past, and this one is the one that take the most throttle before it start spinning.

I've been using only the 8043 SF for quite a while, you get a bit more thrust and doesn't need any adaptor.
If your throttle trim is set to minimum, you'll have to move the stick further to start it to spin than if you keep the trim at mid point.

Re: Blue Foamie

A couple of us are going to get into the "lightening" aspect of these over-addicting planes. I am going to make a vacuum table to hold the foam while it is being lightened and I was wondering what is the best size of router bit to use. I may do a couple of planes free hand but its more likely that I will make a template to speed things up.
What sort of airframe weight reduction do you get but routing out the material?

Thanks
Paul

Hi Paul
When I was milling the 32.5 in Yak by hand a couple years ago, I made a plexiglas platform to hold a Dremel and I used a 1/8 bit. I was using an MDF template sitting on the foam, I didn't have to use a vacuum table, even though it only lightened the foam by 10 or 11 grams, it's a lot when we're dealing with 4 or 5 oz. airplanes.
Today I use a CNC router and just replaced the bit with a 3/16 bit instead of 1/8, the machining time was reduced by 12 minutes, it now takes me 25 minutes. Every time you remove a few grams, you can see the difference in the flight characteristics, everything becomes easier to achieve, we have some older guys ( like me ) who couldn't hover and who now are very proud to show you their skills. What make the blue foam so favorable is it's endurance, it will take much more abuse than most other rigid foam due to the density and the thin plastic film on one side.
