I have an autostart Wren MW44 but have been unable to get it going. I first got an error message of "low battery". I recharged the battery but got the same message. I purchased a new battery pack and tried again. I made three attempts and got a "Bad Start" Error message on each attempt. I have no idea what that means. On the forth attempt I got a "low battery" message again.

I have several Wren MW54's that I start with a wand and have no problems. I was thinking about getting rid of the autostart on my 44 and go with a pod starter and an external battery pack. I feel more confortable with starting it and have more control over the procedure. Has anyone else had these problems with the auto-start version and what do you think of getting rid of the autostart?

Thanks.

Have youi checked your receiver battery? I had this message a couple of times on my 54...and If my memory is correct, I'm pretty sure it was the Rx battery casuing it.....

The autostart 44 is no longer in production from what I've been told. A buddy has two 44's, one with a starter included but not autostart. This started fine until the starter clutch jammed on & oversped the electric motor. We removed it & just start it with the wand while the pod starter is being fixed. Be careful with the rubber on the wand starter, it's just a normal grommet & ours split along the groove but fortunately was not sucked in [X(]. I found some large silicon tube which fitted totally inside the starter cone, not half in/half out like the grommet. - John.

As for the the low battery warning, have you checked what that parameter is st at? Its not in the normal menu, its in the one that you access by pressing the first and third button from the left just after you switch on. It should be in the instruction manual which one of the number index relates to allowed ecu voltage. If I remember right the "start bad" comes on when the gas does not get 50 deg above the temp which you initiated the start at.

'Start bad' relates to insufficient start rpm, you should check there is a good rpm reading on the data terminal and that rpm is sufficient for the start process to continue. Lower than 50deg rise in temp usually gives a 'weak gas' shutdown indicaton. Also check your Rx battery is freshly charged.

I have one MW44 with on board starter, for manual start, and it take me about 15 second to get the turbine at a stable idle...

no problem at all.. ignition is perfect, ramping flameless, temperature in range..just like a swiss watch..
no big battery needed in the plane, only 4 small cells for the pump...

Contact Wren direct via email. They are very helpful.

I have a Supersport which had a problem with the autostart and a prolonged ramp up time.

Emailed Wren and we arranged a common phone time and Mike Murphy [official good guy] stepped me through tweaking my ECU parameters.

Problem solved.

Fast is good but faster is better.
