[16:11] <edwardmoore> hi jcoxon
[16:27] <jcoxon> hey edwardmoore
[16:27] <edwardmoore> all well?
[16:31] <jcoxon> yup
[16:31] <jcoxon> so you can't do sunday?
[16:31] <edwardmoore> we need to plan the weekend a little as i need to organise around parents coming up and picking up. my intention is to do one parent trip and then drive back up again myself, so i can be up again monday onwards
[16:32] <edwardmoore> yeah, they're picking me up on sunday
[16:32] <edwardmoore> but i could be up again on monday
[16:33] <jcoxon> right then perhaps we should do mid next week
[16:33] <edwardmoore> ok
[16:36] <jcoxon> i'm easy on which day
[16:36] <jcoxon> i'll email rocketboy and you with some ideas
[16:36] <edwardmoore> that'd be good
[16:36] <edwardmoore> i might take up residence at old school and we can CNC up some stuff properly
[16:37] <edwardmoore> if you wanted to come down for a hardcore build day, that'd be cool
[16:37] <jcoxon> well the first week i have to do my disseration
[16:38] <jcoxon> so that rules out then
[16:38] <jcoxon> (though i could fit in a tethered flight day cause its not far to go)
[16:38] <edwardmoore> lol ok
[16:38] <jcoxon> maybe 2nd week - will have to see
[16:39] <edwardmoore> ok
[16:44] <jcoxon> right so i guess we are waiting for hte r/c stuff\
[16:44] <jcoxon> though guess we could restring the parafoil
[16:45] <edwardmoore> thaT'S PROBABLY WORTH DOING YEAH
[16:46] <edwardmoore> woops
[16:46] <edwardmoore> we need a design that alllows us to adjust the trip easily
[16:46] <edwardmoore> trim*
[16:46] <edwardmoore> just pitch trim, that is
[16:47] <jcoxon> okay
[16:52] <edwardmoore> sorry, examples papering. yeah if you don't mind hacking your parafoil that'd be good
[16:52] <jcoxon> its no problem
[16:53] <edwardmoore> i was thinking we could terminate the things with some sort of mechanism that ets us adjust trip aswell as routing the control lines for pulling the trailing edges
[16:53] <jcoxon> i therefore reckon that later on this week we build the thing
[16:53] <edwardmoore> i'll scribble something on paper for you when i next see you\
[16:53] <edwardmoore> what are you doing on friday?
[16:54] <jcoxon> hmmm i've got a practical in the afternoon
[16:54] <edwardmoore> just remembered i'm busy in the afternoon too. scrap that!
[16:55] <jcoxon> i can do friday morning
[16:55] <jcoxon> or sat afternoon
[16:55] <edwardmoore> same to both
[16:55] <jcoxon> sat afternoon would be best for me
[16:55] <jcoxon> get term out the way

[19:59] <LaurenceB> Hi all
[19:59] <LaurenceB> I'm at home now, just finished making a semi rigid rogallo wing
[19:59] <LaurenceB> sides 1.2 meters long :-)
[20:00] <LaurenceB> will fit servos to it when I get my RC gear

[21:04] <LaurenceB> Hi there
[21:08] <LaurenceB> know what the plan is for the weekend? I.e. cut downs ect.

[23:08] <edwardmoore> not sure it's still happening this weekend, LaurenceB
[23:11] flowolf (n=flowolf@host108-219-dynamic.10-87-r.retail.telecomitalia.it) got netsplit.
[23:11] flowolf (n=flowolf@host108-219-dynamic.10-87-r.retail.telecomitalia.it) returned to #highaltitude.
[23:11] <LaurenceB> ok
[23:11] <LaurenceB> thought it would be hard to get it together in time
[23:12] <edwardmoore> it's more to do with family commitments
[23:16] <LaurenceB> oh I guess your term ends this weekend?
[23:17] <edwardmoore> monday. but forgot that i was meant to be seeing gran at the weekend!
[23:17] <LaurenceB> lol
[23:17] <LaurenceB> have you seen my video?
[23:18] <edwardmoore> yep
[23:18] <LaurenceB> it is unstable in some stall conditions tho
[23:19] <edwardmoore> nothing a dash of trim won't fix
[23:19] <LaurenceB> yes but I'm worried tubulence could cause it to fold up
[23:20] <edwardmoore> it's rigid isn't it?
[23:20] <LaurenceB> so on my big one I've added a horizontal bar
[23:20] <edwardmoore> it's as unfoldupable as you can get before actual ings
[23:20] <LaurenceB> yes, completely rigid now, apart from the envelope
[23:20] <LaurenceB> theres m3 bolts so it can fold up for transport
[23:21] <LaurenceB> i.e. train!
[23:21] <edwardmoore> cool
[23:21] <edwardmoore> lol
[23:21] <LaurenceB> the big one flies without a payload
[23:21] <LaurenceB> which is a good sign
[23:22] <LaurenceB> if it has a 1kg payload it will have 4x the wing loading of the model one
[23:22] <LaurenceB> so should fly twice as fast?
[23:22] <edwardmoore> dunno
[23:22] <edwardmoore> i'm trying to write a program for 6800s in hex
[23:23] <LaurenceB> ouch
[23:23] <edwardmoore> uhuh
[23:23] <LaurenceB> airfoil lift equation says lift proportional to spedd squared
[23:24] <LaurenceB> http://www.youtube.com/watch?v=sADQ7ViG3rc
[23:46] <LaurenceB> ok I'm off cya
