How to spool it up if only switch for on or off????????????

I have had my tj for 6 months, I love it. I use the pot to set the rpm. I don't understand how to use it the other way and can't find after searching and reading everything. I have a rd8000.

I want to have the throttle follow my curves in normal mode. I want to have two seperate headspeeds that which I can vary from the tx.

I don't understand how you spool up by using a switch. I have no throttle control. So what do yall do start it up then just flip the switch and it guns the motor until set rpm.

I found some pics of it and just realized that I got the piece of crap one that does not offer that feature, it does not have the auxillery channel. It only has one set of wires coming out of it. No aux.

I bought it from Heliproz. I am sure I ordered the remote version. I guess it only took me 1/2 year or so to find out my order was wrong. I sent them an email for a copy of the order. I will see if I accidentally bought this crappy one.

Looking at model avionics site it looks like all I need to do is solder the leads on though. Both version seem to have the same components.

To vary your headspeeds remotely you must have the remote TJ. The TJ will only engage at greater than 25% throttle, and AFTER you have reached the desired headspeed. You'll never just hit a switch and go to full blast.

So essentially you will spool up as usual on your "normal" curve... when you hit the desired head speed the TJ will begin to manage your headspeed. It is smooth and seamless. When you land you will reduce the throttle below 25% and the TJ will pass control back to your radio to spool down. With a two position switch you can only have two speeds, and always be engaged, or one headspeed and off.

I find it works very nicely on the mode switch... off for normal, mid range speed for idle1, and ballistic for idle2. Saves reaching for that extra switch to change speeds. Easy to get a suprise when you hit the gyro rate switch instead of the headspeed.

Don't just solder to the board without at least emailing Paul at modelavionics. He's a very helpful guy and will let you know if it will work. He may be happy to swap you a remote version for a small fee as well.

Good Luck,

Mike
