New Edge


       Remove this ad - become a site supporter!
Running a few prototypes of an Edge on the CNC out of blue foam on the vacuums table. Right now playing with the wingspan and aileron size to increase the roll rate. Flyís more like a larger plane and you can make very nice aileron turns without rudder input. With the larger span so far and the low rates on even beginners are enjoying flying around in high alpha. The re-enforced nose takes a lot more abuse than just straight foam. The whole thing is interlocking so you cannot get it wrong or out of alignment. Even the servo locations are milled.

Re: Blue Foamie

Hi Dennis
That looks awesome, I just finished building my own cnc, I built it to mill and reduce the weight of the blue foamies. Is this your own cnc and is it homebuilt, hard to tell from the video. I brought the AUW down to 5 oz on a YAK 55 and what a difference in handling, it was like night and day. Thanks Dennis, can you post more pics of your cnc and your foamies. The YAK shown in this pic was milled by hand a while ago but it's the same idea with the cnc.

Re: Blue Foamie

Hey Gaston! You guys are going hi-tech with the cnc stuff! I thought I would share my latest "BF" Yak. I increased all dimensions by 10% of the original FF Yak. I am using the same Hobby King motors and servos you guys are using. So far I have only flown it outdoors with 2S 500mah, using a 9x5 GWS prop. I find that flies incredibly stable and makes 3d manouvers a little slower and less erratic. I bet you could easly scale up the dimensions on the CNC mill! Heres a picture for comparison of the size vs the original. Weight = 7 oz with a 2s 500mah. My originial size BF Yak comes in at 6oz with the same battery.

Cheers!

Hi Andrew

Slower 3D, that would help the old guys like me, something to consider, thanks for the tip. Where's our friend Andrew C. you guys should come to our Swap meet/indoor flying April 25 it would be nice to get together again. How come that plane still looks like new, probably bacause you haven't flown with all those nuts at our gym, except me, naturally.

Gaston I must have missed your answer thanks for sending me a pm. Yes I am busier than a one legged man at an ass kicking contest. To answer your question about the mill itís the same Bridgeport style mill only I made an aluminum adaptor plate that clamps to the spindle of the mill and holds a Boche Palm Router. Then without turning on the spindle I use the table and head to move the router bit across the work. I have not tried milling out any of the foam to lighten it as most of our guys are still in the banging heads stages. I suppose once they are looking for a greater challenge I can try milling out the foam.

Re: Blue Foamie

Dennis

Thanks for the reply, that's a pretty advanced milling machine you're using. I'm still working on little problems with the software and the leadscrew for the x drive which I'm replacing with a timing belt system, it will be much faster and without vibrations. As long as I'm ready for next fall, I'll be happy.
I'll keep you posted on the project. Your interlocking of the components looks pretty good and solid. I like your comment on how busy you are, never been on one of those contests.

Re: Blue Foamie

hey gaston i have been making the foami that i was talking about, the delta design i am aim ing towards the stealth look and it seems to be going good know i was wondering if someone could help me out with this is i want to put the prop in the body and i am not sure what size prop i should use because i want speed but i also dont want the prop to hit the ground, and is there a type of engine where when the throtle cuts it goes horizontal maybe some one could help me out with this

Hi
You have to give more information or pics , it's hard to figure out otherwise. It depends on the motor, the battery, the esc, the weight of the plane...etc, if you're using the same equipment, we're using with the foamies like the Yak 55 then if you want a smaller diameter prop, you'll have to go with more pitch.

Re: Blue Foamie

how would you make it so when you cut the engine the prop stopes horizontally so when in the middle of the plane to can land with no gear without hitting the prop or do you have to have a cetin type of engine
