Re: "Cox Gravity Warbirds" F4-U Corsair RC upgrade thread

Older radio systems use FM or AM modulation so only 1 person can fly on any 1 frequency at a time. Depending on how old your system is, it may not still be legal to use if it is not a Narrow Band system.
Newer 2.4 Ghz radio systems actually set up a computer link (Mac Address) from transmitter to receiver. You "Bind" the receiver to the transmitter to establish that link. With the newer 2.4 Ghz systems many people can fly at the same time without radio interference since you are actually sending WiFi computer commands to the receiver. Collisions are another story...
Last year at the NEAT fair we had close to 60 aircraft in the air at one time during the Mass Warbird Launch.
Talk about mass carnage Shocked
The radio system you choose is a personal preference. I use a Horizon Hobby Spektrum Transmitter (DX8). The DSM2 / DSMX protocol is the most popular giving the widest range of choice in both Spektrum & aftermarket receivers such as Hobby King, Lemon, etc. which brings the price down.
You can use any servos you want, only the Transmitter / Receiver is proprietary. Hobby King makes some nice, small, inexpensive micro receivers, some that are even 3 axis stabilized with built in gyros. I have never been "Shot Down" since switching to 2.4 Ghz system.

Thanks again for all the info. Your stealing my thunder. I was going to cover the radio systems when I got to the installation part. +1 anyway.

I started with a $25.00 system for receiver and transmitter. It worked fine for me, except I wanted to be able to mix elevator and aileron for a V-tailed sailplane. So I spent $35.00 for a used radio system. It worked fine for me until...  you get the picture. There is always something else you want to add. My current transmitter, similar to Larry's, is a Spektrum Dx6i, It lets you store up to 10 different types of aircraft settings. So I can have 8 aircraft and 2 helicopters or whatever. And you can save all the settings you want like mixing rudder and aileron, or aileron and elevator, set the range to any % instead of 100%, have dual rate controls, like 1 = 100% and 2=45% or however you set it. This type of transmitter is in the $100 to $200 range. I paid $70 for a used transmitter. and it had just been updated, for free, by the manufacturer due to a low percentage defect in SOME of the joystick potentiometers. So the manufacturer replaced a lot of the older, not brand new, parts for free.
   anyway. ask before you sink a lot of money into something new. Checkout the manufacturer for complaints, Google, and ask friends.

Continuing the build topic of the Spitfire

Post  happydad on Tue Aug 25, 2015 12:33 am

I took a few more pictures of initial mounting of the power ON-OFF?charge plate and the eleveator and rudder servos for the Gravity, (Cox), Spitfire.


first adding glue to both the charge plate and the area where it will go.


second adding the charge plate to the fuselage.


then adding a weight to the charge plate to keep it in place while the glue dries.

The pictures of the servo area did not turn out, white on white, so I'll have to finish this later

That's all folks.

Dude I'm trying. I stayed up all night to add the pictures of the Spitfire internals as I was placing the servos and the power/charge plate. I had to wait for the glue to dry, take the pics then post them.
 And $25.00 for a 2.4GHz radio system isn't too much booty to start with.
    hey I'm retired and rely on coke cans, ebay sales and misc. other stuff for my booty and I'm 70 with a left hip replacement still rehabbing.

More pics ?

Post  happydad on Wed Aug 26, 2015 1:03 am

I was all ready to add more information on the Gravity, (Cox), Spitfire in the internal parts area, but surprise Win10 asked me to sign in to a windows live account and create a new password, the I restarted my PC and my start password was gone and Win10 asked me for a PIN?. What did I get myself into. I had upgraded 2 other PC's to Win10 today and no problems. In fact I wondered why the new updates looked normal and my 10 day old Win10 update still did not show desktop icons. Whatever. Mine only, not the 3rd desktop, or my wife's all-in-1 desktop she doesn't use because she has an iPad, my laptop??

Anyway all my pictures are on the PC and my editing tools so I will continue as soon as I fix this bug.
Sorry.
