Model Forum / Radio Controlled / Helicopters / January 2005Heli-Chair, a different way to fly your helicopter
I have created a new and unique way to fly your remote controlled helicopter. Similar to the Fly Seat created by Ed Henry a long time ago, but much refined. Take a peek at my website! http://www.heli-chair.com >I have created a new and unique way to fly your remote controlled >helicopter.

Some suggestion made at the time where. It could do with a set of wheels to push yourself out the way of the heli coming at you. You might consider wearing full leathers and a catchers mask while using it. And another idea is, you could have a space allocated under the chair so that when all else fails you can leap under the seat to avoid the out of control heli. Certainly looks interesting!

The chair looks good, however your electronic skills are probably not as good as your mechanical. I just feel sorry for these transmitter you modify. You don't have to do that. You only need a US$5 microcontroller to read the potentiometers and generate a PPM signal which you can then feed in the transmitter from the training lead connector. Thus you don't even need a second TX set for the instructor. angelos, you are aboslutely right that i could use a ppm signal generator (and my microcontroller knowledge is limited), however there is a good reason. the flimsy trainer plug on the transmitter always comes loose and is not as reliable as a circular locking plug. second is that i am interfacing much more that just the signals for the stick positions. i am interfacing with all of the toggle switches on the radio which do not go through the trainer plug and in some cases the digital trims as well. i was not aware that all of these passed through the trainer plug, am i wrong? kas ps. informative website angelos, you obviously know a lot about the futaba 9Z! > The chair looks good, however your electronic skills are probably not > as good as your mechanical.

But the training connector solution has some disadvantages... mainly because you loose most of the TX's capabilities like the mixing functions, model memory storage, pitch curves etc. You see, by using the training lead, you turn the TX into a "dumb" transmitter that just passes the signals it gets to it's TX module... (Except if there is a radio out there that will treat the PPM signals as "stick positions" so that all the radio's functions could then be applied to the signal before its transmitted). So, the US$5 microcontroller must provide functions like pitch curves, model memory storage and basically everything a programmable radio offers today..! It's feasible but a bigger project than just a PPM generator :-) <angelos(spam_stop)@model-gadgets.com> wrote:... > The chair looks good, however your electronic skills are probably not > as good as your mechanical.

The Futaba 9C does ... but ... like was previously mentioned, it only does this on stick channels ( 1- 4). The 9Cs trainer mode can be set to OFF, NORMAL, or Function. OFF - tx'd signal based on Master TX and buddy box signal is ignored. NORMAL - Signal from buddy box is sent to Master TX and tx'd as is ... with no manipulation from the master TX. Function - Signal from buddy box goes to Master and then any mix function that is enable in the Master TX changes the signal before it is TX'd. And make sure the TX IS in PPM mode. Trainer cords don't work when the master TX is in PCM mode. Either way ... You'd have to prove to me that more than channels 1-4 were being set across the trainer cord before I would try it. tippy I see, thanks for the info on the 9C. Maybe in the future more TXs will support this, and for all their channels (not just the 4 sticks...) <dtipton@NOSPAMworldnet.att.net> wrote... > > (Except if there is a radio out there that > > will treat the PPM signals as "stick positions" so that all the [quoted text clipped - 18 lines] > > tippy One slight correction. Make sure the "slave transmitter" is in PPM mode. Trainer cords don't work if the "slave" TX is "not" in PPM mode! The "master" TX has to be in whatever mode the model's receiver requires. The last person I helped using a trainer cord had a PCM receiver in the helicopter so the master TX transmitted in that mode but the slave TX still had to be in PPM mode to communicate with the master TX. :-) Fly Safe, Steve R. > And make sure the TX IS in PPM mode.
