Wren Kerostart
 

I have an old Wren 54 Mk3 with a ECO (manual start) ECU which I'm thinking of upgrading to kerostart.

Is anyone here running one of the newer kerostart Wrens and, if so, how are they? I know the engines are good but am interested in experiences with the start cycle. Is the start reliable? Are the plugs reliable?

Starts every time No problems at all. The nice thing about Wrens Kero plug, they are user changeable. I hava a spare, but have never needed it.

Here is a post in the Wren support forum showing how to set up their kero start conversion including a video. It's something they just added and looks good so far.

Wren ( UK ) will be holding their Spring Open Day in April. You are welcome to attend and have one of the staff guide you through the conversion!

Hi S'33,

I have three Wren 160s and one Wren 100, all kerostart. They start very smoothly and while Ron did supply me with a spare for the Kero plug I have yet to replace one.

I've attended the open day before and it's a great time .. and a good way to get the upgrade done and have some great food from the Man Grill :-)

Hope to see you in April, Ron!

Cheers,

I'll probably upgrade mine before the open day:D My engine has been removed from the model for a small tweak so now's a good time to do it. Good to hear that the system works well (which isn't a great surprise) and I'm looking forwards to ditching all my off-board starting cables, batteries and gas!!

Keep in mind.....these are smaller engines.....how much weight extra is Kerostart?

Your plane will not know the difference. If you carry an onboard Propane tank , the weight will be less.

RE: Wren Kerostart
 

An ounce or three depending on the battery you choose. On a 20 pound jet there is probably 2 ounces of dead bugs on the leading edges. For ARF guys, Get a dremmel tool out and grind away that extra glue seeped out of over glued joints that isn't doing anything but riding along without a ticket, that's 6 ounces right there. Even on a Wren 44 powered model (and I don't think you can get auto start on something that small) 2 ounces will even be manageable I'd think. If it's too heavy, then it's too heavy somewhere else. :)

RE: Wren Kerostart
 

The Wren 44 is auto-kero-start.

RE: Wren Kerostart
 

It sure is. I've got three 44 Golds, they are all auto-start, and they are a dream to fire up on kero-start. No more carting the propane bottle around in an inside pocket in my coat to keep the gas warm on winter days :D

Just a quick update to say that I did upgrade to Kerostart. I ordered the parts from Wren and Xicoy and did the conversion myself, which was incredibly easy. My first attempted start was this evening and it fired up first time :D.

This engine previously had a ECO ECU so I can now leave the starter lead, battery, gas canister and connector, glow plug and glow lead at home. Much more user friendly :D
