I recently purchased an Evolution45. I am having trouble with the wiring. The manual has only one wire for the battery to connect to. That is simple enough. However, my ignition box is different than the box that is most commonly seen with the evolution 45gx motor. The ignition i received was the TY 2 Ignition. Its sold on Horizons website but i cannot find any tech support for hooking the wires up .

In the pictures you will see the different places for the wires to connect. It came with 2 wires seperatly from the ignition and one wire comming from the ignition that is not removable. The instructions say that the battery is connected to the orange/brown wire comming out of the ignition. Ok, simple enough, but i have no idea where it might go. If that is the case, the plug on the connecting end is male. It would need to be female for my JR switch to connect to.

The wires connecting to the ignition box each only have a 2 wire plug. One is the orange/brown and the other is a light... i guess to put somewhere for an ignition power indicator light.

From the pictures below, you will be able to see what i am talking about. Im thinking about just ordering one of the other ignitions that has only one wire. This is my first gas motor, so all of this is new to me.

any suggestions or help is appreciated.

I think you got the new MVVS 45 - lucky you! Unfortunately, I can't help you on what to connect where.

But my bet is that one of the plugs are for a choke servo. The new MVVS version automatically controls choke and will choke your engine during starting and during idle. This should make it possible to run the engine at an incredible low idle.

Yep you did... wanna trade with the old Evolution 45? Almost broken in and MUCH easier to install the ignition.

Look at the plug to the left - that's for the choke servo. The other 3 must be for the probe, LED and battery.

Please let us know how the auto choke works once you get it startet.

My motor is identical to yours. The choke is the same as well. Do you think i just got the mvvs ignition?

Maybe so, but i sure cant find out anyting on hooking this thing up.

http://www.rcuniverse.com/forum/m_36...tm.htm#4364801 You can look on my post for some new ignition , maybe will not be so helpful though.

some advises is that you use a six cell batteries 8.4volts , the range of the new ignitions are 6-8.4 volts. you have to connect your batteries to the wire that is coming out of the ignition and the lamp you have to place it at the top slot , the lamp is going to giving you some signs of your batteries power. when your bateries are full charged then when you switch on the ignition then is going to light on and off 2 times and then is going to go off that means everything is OK to start and you have fully charged batteries. when you use 5 cell or most probably when your batteries are almost empty then the lamp is going to be on all the time you will be able to fly but once your engine is off the ignition will not allow you to have another flight. and if you put less cells of 5 , for example 4 cells then the lamp is going to be lighting on and off all the time that means no chance to turn on the engine you don't have enough voltage.
Last thing at the place where it says servo there you should use a standard servo and you should connect it with the choke of the carb to regulate so that your engine functions better at low rpm.

I hope that i have been helpful.

Yes the engines are identical except for the sparkplug, which is smaller (I bet?) - that change is not related to the auto choke though.

The choke on the carburettor is not special - the auto choke lies in the ignition only. The ignition just controls the choke servo, rather than your reciever. The ignition senses if the engine is about to quit (revs dropping), and subsequently it closes the choke a bit. If you are starting the engine, is senses no revs and closes the choke. When you flip the prop, and the the engine pops, the ignition immediately opens the choke. Should make for the easiest starting engine ever.

If it works as advertised......

There has been a update to the Ign. setup on horizons site The suppliment that cam with my Evolution 58GX-2 was incorrect for the programing. here is a link to horizons bulliten :

http://www.horizonhobby.com/Products...odID=EVOE58GX2

Im currious as to what voltages you are seeing for this ign. to show a battery to low state?

I was unaware of the choke being actuated after the engine had been started

im attaching a pic of the wirring setup that came with mine might help a few with out this wiring setup.

I was wondering is a Li-ion 7.4 would be a good plan? I have tried to use a 6v Nimh and have had very bad luck one flight is all ive got out of it the battery shows 6.6v and the light flashes on the ignition indicating a dead battery. I put a 1/2 amp load on the battery and seen it go as low as 6.4v eather way Ive never managed to get more than a flight out of it No matter what I have to replace this battery with something better than this. Im kind of frustrated with this as ive flown my edge with a DA for days without charging this pack and have never had an issue with it. I would like to have 2 hours run time if not 3 out of a battery pack When i fly i want to fly not worry so far this isnt it.

I had a 7.4 li-ion battery and 6.0 regulator with this motor...

I talked to horizon monday, they said thursday i will know whats wrong.

bluemagic98, yes 7.4v Li-XX is a good plan. As far as I understand 6 volts is the minimum and a 5 cell pack is not to be used with this ignition. Use 6 cells or 7.4v Li-XX.

wttiger42, try removing the regulator - you don't need it as the ignition accepts 7.4v without the regulator. Again 6v is minimum and should be read as the engine will accept a 7.4v Li-XX pack that has been dischanged down to 6.00000001v. With 6.00000000v you get low voltage warning.

Horizon has the motor now and i should find out tomorrow what is wrong. Hopefully it is something covered under warranty.

The older ignition takes i think 4.8 vlt.... you are right about the new one, 6-8.4.

I think your geting my point It says 6v but dont use one? frustratig to follow directions and have something not work and i get a low battery warning at 6.4v, 6.5v or more

Well Horizon told me monday that they had tried a new carburator, new reed valves and a new ignition. They do not have a clue what the problem might be. They only were getting around 5000 rpm as well. They sent me a new motor that arrived today. It was covered under warrenty. I put it on the plane and after hooking up the auto choke ignition, it fired after only 2 flips. Right out of the box. Two friggin flips. I couldnt belive it.

I havent tached it yet. Im going to break it in with a couple more tanks of gass before i tach it.

Thanks for all the suggestions and help.

The new ignition module from MVVS has a different power requirement:
ICU - L (Light) 6- 8.4volts
ICU - S (Standard) 6 - 8.4 volts
ICU - P (Professional 9 - 13 volts.

Good input on the MVVS Support thread.

Mike

The voltage requirements for the new ignition are listed as 6.0 - 8.4 volts. the ignition will operate at 6.0volts, but the module will not allow a start below 6.5volts. A fully charged 5 cell NiMh or NiCad pack is about 6.7-6.8volts. The best bet for weight and performacne is a 2S Li-po or Li-Ion pack.

Pete

Glad that is clarified--
as a side note--
for those who really have no desire to use Li Po or Li Ion- just order a small 5 or 6 cell high output NIMH pack
Horizon has em -- Cheap Battery Packs / NoBS will make em --and you won't have to worry about running the battery down till it fails.
For those who don't know this -- the Li pos/Lions will become unusable ( fail/ quit/ die) if voltage goes too low .$$$$$$ error
I use Lots of LiPos -but in electric models which have low voltage cutoffs.
Be informed before you make a potentially expensive mistake .

This is how my plane wound up in a bush at the end of a field. The lable on the ignition wire says 6v-8.4v and the manual says "2x Li-Io / Li-po or 6x Ni-Cd Ni-MH " Now im no expert but i dont see where any thing here is 6V and i had a 6v Ni-MH 1200 Ma and it continually failed on the first ignition I had durring the setup procedure. I could not hook a choke to the ign. as described in the manual without the ign. signaling a failure. I cycled the battery it was fine. The ignition was replaced I had similar problems after 1 short flight the battery tested at 6.5 - 6.7 volts under .5 amp load and the ignition continued to show a battery failure. I have purchased a Li-Io 2400mah relion pack from fromeco {great people to deal with} and now i can fly this thing but ill need some new landing gear wheel pants and some ultracote to repair the scars from this experiance of reading a black and white lable saying 6v-8.4v attached to the plug wire that is firmly attached to the ign. Tor said a 5 cell pack is not to be ussed use a 6 cell pack show me a 6v 6 cell pack? show me a ussable ign with a 6v pack you can say a fully charged pack is 6.7v but under load? is it safe? would you risk it? I hate to sound like im upset But there is a huge lable that says 6V -8.4V on this ign that is just not the case and is very very dangerouse to me my fellow club member's and yes im very upset my Ultimate is parked I dont want to fly it I no longer trust it some one have a huge cub to put this motor in? the motor and the ignition may be just fine in fact I think after 1 gal that ive burnt with iti may actually decide i like it againsome day. This plane is 19lbs all day long and after all ive been through with this 6v theory Trust is something thats just going to take time and posably a new air frame cuz this one has seen some action I dont care to remember.
20 20 hind sight allways read the fine print on the back page of the manual

I read through the thread. I am looking for input for my new 58, however it must have the old ignition. I simply have a battery connector. And in the manual it states to run a 4.8-6volt batter. Minimum of 800ma. Does this sound correct? I plan on using a 1500ma 4.8v Nicd.

ive had both the new and the original. the original had a larger plug and the cap had to be held in place with a set screw that was part of a collar that was pressed into the head.
