Status: offline 		Well isn't that cool my spinners finally came in and I installed the magnet ( the right face out to get the green light ) and now I know that my Hanger 9 HD starter turns over at 300 +/- rpm on the LED display .... Bill? is the the green light to stay on as the the rpm builds up? mine flickers as it spins up but seems to miss a beat or two.

PS: I had to rebalanced the Dave Brown spinner after magnet was install ..but I have well balanced now ( took a 1/2 hour each )

Status: offline 		PS... extra magnets are $1.50 per pair. You can rebalance the spinners by buying an extra set of magnets and installing them 180 deg apart on the spinner and facing them other direction so that the sensors do not detect them (1-2 minutes vs. 30 min.). Sensors should only detect one magnet per rotation... there are cases where one might want two magnets but it would be an extreme cases for scale competition aircraft only where sync is customized for servo and carb geometry and sync accuracy can be increased from 100-130rpm to <50rpm.

Not easy to do...

I keep waiting for an email from the serious twin engine scale competitors asking for it... any takers.... If anyone has Greg Hahn's email address please email it to me.

Status: offline 		Bill: With time on my hands I connected the rudder servo to a "Y" cable and attached the it to the ALX channel...changed mode 6 to rudder and tested .... found that my rudder nose gear responded correct but the engine respond to the same side I am trying to turn into ...is there away to reverse the engine input?

in other words ...standing behind the plane and give left stick the right engine should increase ... right?

Status: offline 		I need some assistance from a Twinsync guru. I finally got everything together and the perfect weather to do some ground runs. I'm having an issue with the starting of the second engine. Here's the details:

1- fueled up
2- All batteries charged, RX and both onboard glow
3- THrottle travels set: H150, L100
4- THrottle servos are normal, not reversed
5- Either engine starts fine, onboard glow works great
6- WHen starting the second engine, it surges a few hundred RPMs, then both engines shut down.

Any ideas?

Mike

Status: offline 		Blade47,

Exhange engine servo and sensor connections on the twin sync and you have reverse the rudder steering direction. Rudder steer is not disabled on a dead engine. I think it probably should be now thinking about it.

UkerDuker,

You need to reprogram your idle points. Idle point are the lowest position the Twinsync can move the throttles. So it is either trying to sync them too low or trying to idle them and killing them. Even though you are at 150/100% I have found different brands of radios are very different in their timings. So unless you have a Futaba 9C set at 100/100% you will have to reprogram idle and full throttle points.

So here are the Steps to follow:

FIRST MAKE SURE DIRECTION IS CORRECT...
1. Make sure both yellow LEDs are off at idle. (if not you need to increase your idle EPA or throttle on transmitter is backwards and should be reverse (some brands have to be reversed).
2. Move stick off idle and one Yellow LED should come on just above idle.

For 1.4.x and Software: NEXT SET IDLE POINT, FULL THORTTLE, AND SYNC ENGAGEMENT POINT
1. Move your EPA (high and low) where you want them (at least 100% for most accurate sync).
2. Power up twin sync with rotary switch in position 3. Move throttle stick to where you want the TwinSync to idle them on a dead stick. Push each button once until the yellow led flashes. This sets the lowest point the TwinSync can move the throttles while both engines are running.
3. Move Rotary switch to position 5. Move stick to full throttle. Then push the button furthest away for the rotary. This sets the full throttle point.
4. Now move the stick to just above idle to where you want the sync unit to engage. Push the button closest to the rotary switch. This sets the Sync engagement point.
5. Move rotary switch to 0 and you are done.

For 1.2.X software (no one should have the older 1.1.X software that was sent out with beta units at this point) then the following is what you do. (If you purchased from RCS then you have 1.2.X or newer.)
1. move stick to high idle.
2. power on unit with rotary in pos 3. After lights stop flashing push each button to set idle point of each engine.
3. Move stick to full throttle and move rotary switch to pos 5.
4. Press each button once to set full throttle position.
5. Turn switch to 0 and you are done.

OK, SOunds like a plan. I know the yellow LED were off at idle. I did this by adjusting the Low endpoint. I thought this would fix it, but I guessed wrong.

By reading the instructions, I assumed the unit was setup to plug and play. (Guess thats what I get for assuming) Let me try to set points on the unit, and give it another try.

I cant wait to hear this engines purr.

THanks,
Mike

Status: offline 		OK I will change them out and let you know how that works to reverse

second question.
" Make sure both yellow LEDs are off at idle. "? ARE both yellow led to be on as you increase throttle? I only have the one come on.

Status: offline 		OK, I think I fixed one problem and created another. I followed your pervios instructions, but the yellow light did not "flash". It stayed on when I pressed each botton for the first step.

Now when I run up, both start, but they do not sync from my sync point. As I increase the throttle, they sync and they both alternate by surging to full throttle. WHen I get to full throttle, the sync last for a few seconds, then one engine drops back to idle. If I continuously move the throttle, they both stay in sync, but only for a few seconds.

THis plane will have plenty of power when I get the two to sync in all throttle positions! I was afraid to let my rebar posts try to hold it back at full throttle.

COuld I have received a unit with the older software? My instructions had 1.4.X on the cover.

Status: offline 		If you got your unit from RCS the last month or two then you have 1.4.1. I just wrote these instructions above in my post from memory so the leds maybe should stay on.

I think I know your problem. I think you have the starboard engine sensor connected to the port sensor connection and vice versa. Look at your manual and I expect that you have version 1.4.1. on this version the connections are the following:

top connector = Sensor engine 1
second connector = Sensor engine 2
third connector = Engine 2 servo
fourth connector = Engine 1 servo
Fifth conn = throttle from RX
sixth conn = aux chan (optional)

All other SW versions third and forth connectors are the otherway:
third connector = engine 1 servo
forth connector = engine 2 servo
