The foam came cylindrical and about 36" long, I think its an 8" diameter. It was around $30 from a Physical Therapy place when I seperated my shoulder.

I cut the internal compartments with an exacto knife and plucked by hand, otherwise the rest was cut with an electric turkey knife. (visible in photo number 7 in the link above). The knife must be 30 yrs old, borrowed from my parents. If you buy one of those 'tools' it'll come in handy slicing meat too.

Its supported by the sides and squished in pretty tight. A servo on one side for direct drive tilt with a cutout in the foam to slide over it. I have double sided tape for the receiver antenna inside and it also holds the foam from slipping. It doesn't really move, you just have to make sure its level when you install it. On windy days you can rotate the foam to make up for mast tilt and keep the horizon 'close' to level.

Now that we're talking about it, I like the ball much more than I like the servocity setup. I think I'll change it back. It looks cool too.

Jason, what size ball are you using for your plane? I'm hoping 6" will fit my A640.

Hi Troy

Thanks for all the info. My ball outside dia is 132mm (6" = 152.4mm)
I'm using a Nikon P5100 so I dont know how it will compare in size to your Canon. Actually my ball halves are plastic dishes. If it works I will get a company here to mould lighter ones for me.

Regards

Ok guys, quit bragging about your balls.
Troy, your mast ball looks way better and more professional than my homebrewed robot looking, wires everywhere mast head.

Flying the stick the other day without ailerons in a small field surrounded by trees...crashed into one of them after 3 loops. I got too close and couldn't turn away from the trees. It planted in the tree, did about 3-4 sommersaults, and exited the bottom...I hit the throttle and if flew away!!! I was laughing the whole time....with the heli, I would have been crying. Minor wing damage...ok, a little more tape please!

I just added some ailerons last night. I ordered the light weight wheels. What guage and kind of metal are you guys making the landing gear from? Plain steel would probably be too soft, right?

Hey Tip, I get my wire from Home Depot. The have a section of nothing but different diamater steel wire, flat aliminum, all kinds of goodies I use on my SS. For my small SS I use 1/8 for my gear and its a trike setup. Its very strong and light.
These are the wheels I use. Dubro Super Lights. They are just crazy light. .5 ounces. I use the 3 inch for taking off on and landing on the Alaska tundra.

This has nothing to do with my SS but because I shared my cross over flight here I was hoping someone here could help me. We are using a 2 way radio for communication when doing the cross over flight from one pilot to another but finding it difficult to also operate the 2 way radio and also hold the TX/Ground station. We have tried the 2 way radio using 2 methods. 1st we had the 2 way radio's on our belts using the earphones and voice activation. We found with other noices around the voice activation is not suitable. The 2nd way was similar but without voice activation and we then pressed the button on the in line mic but that means you have to take your hands off the control to get to it and it is not easy to find the in line mic and end up taking some time before you can grab it nicely to press the button. I'm also not keen on wearing the radio on my belt and feeding the wire through my clothes everytime. My idea is to fit the 2 way radios to the 2 TX/Mobile ground stations and fit a switch at the back of the radio and then maybe even have a extended boom with the mic/speaker on it, this will depend on how loud and clear the radio is without it and it might not even function anyway because we will have a jack plugged into the earpiece on the radio. Here is a pic of the radio below. Can someone give some ideas on how to wire this?

Regards
Jason

Why not use your cell phones with wireless ear sets.

Straight up Tonic, you took the words right out of my mouth. I went the walkie talkie route too with voice activation and it didn't take long to figure that it was a losing proposition. When I need to do it again, I will be using a bluetooth earset connected to my My Moto Razr cell phone.

Friends and Family?

Do you have the friends and family cell phone plan in South Africa?
Carriers here in the states don't charge for those calls!

Hi guys

You mean I wasted my money buying the walkie talkies

mlmcquiggjr we dont have that plan here.

Regardless using cell phones would be an option but I have heard and seen an aircraft crash because of a cell phone. Aparently it will not interfere with radio signal but it can change the settings in computer radios, like reversing servos...etc. I dont know 2 much about that but 1 of my friends lost control of his plane as the cell phone started ringing, if I remember correctly it happened later as well that is when he was convinced it had something to do with the cell phone. I never fly with cell phones close to my TX. With the testing of the 2 way radios I think it will work but I need a user friendly operation. The only problem with the 2.4Ghz radios is that they work far better line of sight. Would be nice if you could have a light weight satellite that could be fitted in the plane and bounce signals from one radio to the other

Hey Jason, I totally hear what you are saying about the cell phone interference. I first heard about that about 3 years ago whe I was using my heli. Anyway, so I ran my own independent tests here at the Alaska Skunkworks. I would fire up the electronics on my heli turn on my TX, and then use my home phone to call my cell phone. I tried EVERYTHING and the only time I could get any reaction at all was if I held the phone litterally touching the RX on my heli. I would get a tiny bit of servo jitter when the phone was ringing. If I pulled it away 2 inches it would stop. It was enough of a reaction to make me think, hmmmmm, I will just take off my cell phone when I fly. Well over the last 3 years I have changed my thinking and here's why. With the sheer volume of cell phones in this country, there is virtually no way that I can protect myself from every possible cell phone that rings. I started leaving my phone in my car when I flew. Which if you think about it makes no sense at all as I would get done flying, go back to my car and have 3 messages on my phone. Which means at any given time my plane was probably CLOSER to the phone when I was flying and was more than likely ringing when I was flying directly over my car. Also, when I am flying in a populated area, what am I going to do, pull out my bull horn and make a blanket announcment to everyone within a mile of my plane to shut off their cell phones? Now I only take off my cell phone just so I'm not distracted byt the stupid thing ringing, and sometimes I just plain forget to leave it in the car. I am no longer worried about MY cell phone as much as the sheer volume of phones that I'm flying over. Good grief their are probably 20 cell phones ringing at the same time while I'm doing a shoot all that are closer to the plane than I am. So in a nutshell, I no longer worry about it. And if I ever need to do a flight again where I need to talk to my camera man long distace, I will use my cell phone.

For sure I'm no expert Jason but I don't think a cell phone use around your radio is the problem. Burg RX are really good at only receiving for a TX that it has been tuned with.

Take a prop off your plane and test with radio and cell phone. Put the cell phone between the RX and TX with the antena down on the TX, that should be a fair test.

Good luck dude,

Forget the Berg RX idea, it would not respond to the second radio.

Hey guys thanks for all the input. Hopefully some of the electronics fundies will chime in now

Kev & Tonic it is not that I am worried about other people with cell phones. I just take my cell and either put in my radio box or car which are often not very far away. I'm not worried about the plane being closer to a cell phone than my TX is. I'm not even concerned of interference with my 35Mhz radio. My concern is trying to keep my cell phone a few meters away from my TX. When your cell phone is about to ring you will often hear the noise coming through on your car radio and this is what I have been told is dangerous and it only happens when your cell is close to your car radio. That same noise can alter settings with programable TX radios. Like I said I dont know to much about it but I have witnessed it take a plane out the sky

I am keeping all my options open so I appreciate all ya inputs

Hey Jason, I totally hear what you are saying. I also understand that its suppose to cause the problem when the phone is to close to the TX. It was just the oppisite for me however, the only time I could get it to react is if I put it over the RX while ringing. I also have experienced the annoying static noise you hear when close to any type of sound system such as your car radio or computer speakers. 6 months ago I switched to a different cell phone company and upgraded my phone to a Motorola Razr and I'm not sure if its the better phone or my provider but the problem is completley gone and I no longer hear that noise.
For me I know I have been either working on my planes while all my electronics are on or out in the feild flying so many times when I had my cell phone ring with no negative effects that I'm not worried about it anymore.

Cool Kev

U probably are right about that chances are so small that it would affect the TX. I will give this 2 way radio a bash for 1 reason only.... I spent money and I hate doing that without at least getting a headache from bashing my head against the wall doing something that a whole bunch of wise men told me wouldnt work in the first place Then I will switch over to my cell phone and never have a days problem and wonder why I spent another sum of money equivalent to what the 2 way radios cost me just to prove I didnt waste that that money the first time

Lol

I am looking at the voice activated set that is on Costco's website. Don't know if they ship to Africa but they do have them in Mexico and Puerto Rico.



What problems did you have with them? I thouhgt of the cell phone but oneday I noticed some glitching and whe I took the phone out of my shirt pocket and put it in the truck I did not notice any more glitching.

I am thinking a system with noise cancelling would be ideal.

The problem I had with them is would would miss entire portions of sentences as the voice activation wouldn't kick in soon enough. The WORST problem though was this. I was using my heli. The noise of the engine would activate the "talk" on mine and then not shut off. Off course then my camera man couldn't talk back to me.

Of course the problem with cell phones is that if a call gets cut then you are n a serious position, well you are if you using it for what I want to. That is why I wanted to cancel the voice activation. I wanted to set it up that you press a button under the TX that is easy to get to. When I get to that I will let you guys know how it works

Hey Kev.

Thanks for you input. I have had the idea for the bipe and long wing for a while for doing video. I have had a few things on my plate but now we ready to start. A few kwik question, can you do video in some wind or only in dead calm weather? Do you have gyros on your mount? Does the wing tips get in cameras way because of it being a long wing with no dihedral? I see you have taken your retracts off, how does that affect the videos?

From my side I did do some tests with the bipe and was pleased with what I saw. It was a quick test using parts of both my camera SS's so could not do all my testing. I have since built 2 new camera ships and so I will take the old planes convert it to a test bipe and do some more tests for payloads, stability, the use of gyros and my AP 2000. In the mean time I'm about to start building a new long wing version like yours so I have been going through a lot of pics and videos that you have given me over awhile.
