Buy the Wren you wont regret it.

Why would I think of buying a second if I was unhappy with the first!!

Its not Gray thats just O.K. I am O.K. too there nothing wrong with my head ask Gray cause he said I was O.K.too.. O.K.

Question for SJN:
Why carry a starter motor when the units starts very well without an onboard starter !

Answer is you dont, unless you want the plane to weigh that bit more which is fine on a 20lb model but we are talking 10.5 lb all up with fuel,and fully loaded !

Remember, starters mean extra batteries and all that goes with it. So you could say, I will start it with batteries not onboard and then will only carry the starter. Thats what we are doing, and not even having to carry the starter.

They fly better when they are lite so I am told. well we are enjoying ours with the Wren!

My dad has ordered a Fiberclassic Extra (2.6m) colour scheme like the one you had at that Nationals stand in place (Fantasy Red).
I will tell my dad though, and will let you know if he is interested.

Im quite sure that you will have the option of a start motor on the engine. The website is not very informative.....But Denmark is a small country, with a small jet comunity.......you hear stuff :-)

"Why carry a starter motor when the units starts very well without an onboard starter ! "

Simple. I dont like the large hatch you have to make in the fuselage so you can insert the starter wand.

Having the starter motor hardly adds any weight. The 8 cell batt pack to run it, stays out of the plane. You only have it connected during start-ups...


Heres a pic of a modified wren with start motor.
and one with the hatch....
Which one would you prefer.....

SJ.

Status: offline 		The picture at the bottom is my plane, the one at the top is a friend of mine. Both use the wand.

You also show a photo of a L39 with on-board start - it's Gaspar's, the only
Autostart Wren 44 in the world! It's been on RCU before, it's an experimental one, and not available. Gaspar's
part of the Wren team, of course, so he's allowed to meddle with engines.

There may be a on-board starter for the 44 at some time in the future, but the truth is, it is so simple and economic on weight to use the wand i wonder if it is needed. I was concerned at 1st but there is no need, it works and has no mechanism to go wrong.

With relation to the Simjet, if you remember the web site used to say they were going to supply with starter on board but have changed the web site recently to do away with it and go back to the wand. So the whispers may be based on old info??
The other thing to remember is the the 44 has been in production now for 9 months (i think) has a good proven track record, the Simjet is not even released yet, we don't even know when it will be.

So in answer to your question 'which do i prefer?' i will take the last picture with the hatch! it is, after all, mine anyway, has flown at least 100 flights and the engine performs beautifully.

I look forward to your pictures, did i send you the engine mount drawings or photo's of installation?
Let me know if you need them i will send them on.

Status: online 		GrayUK, I would very much like the drawings for the mount.
Please send to dakiler@worldonline.dk if you would be so kind.

Nothing is final on the simjet engine yet..... I realy dont have much first hand information.
Lets see what happenes.

But I would still rather have the starter onboard

Status: offline 		That is a non production early prototype belonging to Wren, although it is fundamentaly a Wren 44 it is not as produced and sold. It was made for experimentation.
Gaspar's engine is a production engine modified by him.
Will send info tonight

Status: offline 		Paul,

That L39 is sure an appealing looking plane. However, apparently, it must have both rudders and brakes to be 'legal' in the US under the latest proposed AMA regulations (see todays thread 'New rules presented by AMA').

Does the Savex L39 have an operational rudder? What size wheels does it use?

Finding a set of light weight wheels & brakes for the class of MW44 powered aircraft is going to be a problem on this over-regulated side of the pond.

L Turner
if you order with a working rudder you get a working rudder!! and yes you can have brakes.

The hatch for starting dont have to be big and ugly,

I just cut mine out and hinged at the top with clear hinge tape and glued a mylar hinge as a catch on the bottom, you just bund the hinge tab down and push it shut and it pops into place. To open i just put py finger in the intake and pop it open. ( i have included some pics to help explain) also mine is the "other" savex not the good one although mine did come out at 7Lb 2oz dry.
