Many thanks for your kind welcome on the new members page
Well the Skywalker arrived 3 weeks ago
some progress has been made
I how have Itheater 640 by 480 goggles
the skywalker is built and test flown with FY20a onboard. extra carbon in the boom plus chriss cross fibre tape and the dx6i remote unit in the tail, cables installed to mount the GPS on the tail also
Have upgraded to a 1.2ghz VTX and VRX so i can use my spectrum dx6i
I have built a nice pan tilt with a stretcher on pan and slower on tilt
I plan to let the FY20a manage the rudder and use the left stick for pan (im going to use a servo tester to keep the neutral position input to the FY20a )
Im using the Gyro switch to switch the FY20a in or out
I currently have the tilt on the gear switch
However as the wind has been so strong not managed to get all my ducks lined up to test the FPV yet which is a bit of a frustration
Eagle tree elogger OSD pro and Gyro on the way
Which leaves me a bit short on switches to run the osd system
Im considering using another servo tester to have the Fy20a on full time so releasing a switch so i can set up the OSD system
can anyone let me know if im on the right track please?
Yeah the servo tester trick works fine if you want to do it that way ( saves you a channel ) on the function switches.
Ive never thought about using one for the rudder, good idea, in principle it should work
Thanks for the comments, its quite hard to cobble the whole thing together with just reading posts.
great to get some feedback on the ideas
I will get some photos of the build together and post
just need the wind to ease to get some more air time on the SW and so a chance to get the goggles on

Tell me about it, mine will be delivered any minute, then another skywalker builds coming lol
Hi Indolohouse,
Me to new, not a poet it just slipped out. What gear are you flying on? I am on Futaba FF 9, an old one and an 8 channel RX. It gives me a lot of switches and spare analogue channels. I manage with a little help from the "mixers" to do all that necesary with the FY-21 AP plus PP 117OSD. If I can any one can. I have not as yet fitted Pan & Tilt and when I do I will have to re think the control of the whole lot but thats what I like about life as soon as you think you have it sussed then a little extra requirement changes even the basics, who would have it any other way.

hi John, I have a dx6i and on 35meg Futaba 6 ch and a Jr 6 channel so all the systems i have are only 6 way so im sort of having to be creative as i cant stretch to a few hundred quid for new radio gear
Also now got hold of a 600TVL camera so hopefully the images should be moderatly good
just trying to fathom out how to build some landing gear for the Skywalker with the fact im not using the rudder so tail steer is out
I may use a Y cable off the pan and have the gear on the nose work in sync
just building the gear to be not to heavy is a job in itself let alon how to fix it to a curvef EPO plane

Hi Rob,
Like your style mate keep it up
Regards
John
You can put the rudder onto a y splitter off your ailerons and set it to give you co-ordinated turns
Rudder aileron mixing Coyote ain,t "that lazy flying" ? ;D
Only joking mate your doing a great job for all of us but as some one once said be very careful what you put your name to in the public domain it WILL come back to haunt you eventual. Not a lesson that I ever learnt I have to admit.
Keep up the excellent Work
Regards
John
Indeed yes its lazy :) But if your not using the rudder, you might as well still use it in some way lol
Not being an habitual Forum user until recently I have a couple of questions, actualy I probobly have a couple of hundred :-\ but two will do for now.
What goes "lol" mean or signify after a message or statement ? If its rude don,t answer and of course don,t use.
Why don,t we get a bit more humour and banter on the Forums.
Regards
John
Lol means Laughing Out Loud, now you might notice theres a lot more humour now with all the lol`s in posts.
ROFL = Rolling on floor laughing
LMAO = Laughing My Arse Off
Any of those means its normally to be taken in jest
lol
GQTM...
(Giggle quitely to myself)
I'm glad someone said what LOL means.
I thought it was Lots Of Love
Just thought you guys were being a bit over-friendly. One of the reasons I didn't want to meet up with anyone. phew.....
Got to be carefull with Initial letters. As a young "Tiffs", if you don't know don't ask, we had an expression ROMFT. Some young ladies thought it ment "Romantic Offering For Totty" however this was far from the truth. I think we can spare our readers a full list of all the initials we wrote on the back of envelopes when long distance communications were by snail mail.
God I feel old time I had a nap. :'(

Hi Shikra
I had to ask what lol meant a few months ago.
Lots of Love Gordon :laugh:
Thanks for the idea of Y cable from aileron to the rudder. Am i right in thinking the rudder should turn the same direction as your turn?
also should i limit the rudder movement on the linkages so that it only gives mild movement?
However!!!! linking the Rudder to the ailerons will mean that my FY20a will no longer be keeping the plane on a straight path so thats going to mess things up a bit?
having the Rudder controlled by a servo tester set to mid position into the FY20a seems to help the turns anyway as it constantly tries to level you out even in the turns, it seems to stop you loosing height into the turns
thoughts anyone please?
rob
To get co-ordinated turns you want the ailerons to act against the rudder, this keeps the plane level instead of banked.
If your FY20a connects to your ailerons and elevator then thats fine, it will still turn as commanded but remain more level
Thanks for that Coyote, one last question C of G really 30mm back from the servo slot? is that correct? mine is about 10mm back.
is the amased wisdom 30 mm back for this model thats alot different from the instructions
regards rob
As it turns out it has a much better glide ratio at 30mm back, requires a lot less control throws and doesnt pitch on throttle up
If you want flat turns then use the FY20A to keep the wings level and just use rudder the steer the plane. On the Skywalker the rudder is so powerful this works well. No need for coupling and it reduces the number of channels needed. This is good for photography but lousy for aerobatics.
Ahh electric mick, so your sugesting move the rudder to the right stick and let the Fy20a manage the aileron that might be an idea! I just came back from my first fpv flights with goggles, spotter and son all in tow, fist flight was ok but managed to lose control close to a house on the edge of the green and ran into a small tree, No damage but i suspect the wifi from this house may have caused this
I was using the spektrum, my ground station was a good 200m from this house and i was picking up a wifi network on the laptop that was recording the flight.
next time i shall stay well away frm that part of the green.
net result 2 flights about 8 mins each was amazed at how high i got, it did not look much through the gogs, need to listen to the spotter a bit more as he was having 40 fits that i was so far away, light was fading but clarity was very good.
When i turned the FY20a on it had a tendancy to make the plane nose down a little, i could trim this out but think i need to mod the position a little. lift one end or the other
Will try to edit some footage together, I was flying at pinknies green, just outside of Maidenhead and could just about make out the tall bits of Slough, and over the ridge to bits of Marlow.
returned with plane intact so all in all a good start.
Will have a tinker with Elevator and rudder control only until im comfy then the Eagletree kit needs to go in, plus a mic. all of which are in a box in the workshop
cheers for all the help so far guys
