Hi, to start my phoenix ASK 21, span 3 meter i use also a startdolly. the biggest problem from using a startdolly is: it somewhere on the field and you need an other person to retrieve it.
During this summer i have experimented to create a return home system, by using an Arduino, GPS and an Ultra-sonic distance sensor.
In de link one of the first testruns.
In short, the dolly has 5 wheels, 4 (black) are used during take off, at return home there are 3 wheels ( 2 black and 1 blue) used.

Hi All, in he past i already posted a drawing from a wire bender to make your own.
In this post are also some links with short video's how to use the tool.
The tool can be used up to 4 mm ( 5/32" ) piano wire.

Hi All, I started the build from the Flychatcher as an autum project. Due problems with my camera i lost a lot of pictures made during the build but here pictures how far i'm now.
The next thing i plan to do is create Mort's brother Lionel.
Will post new pictures soon

Sinds my first discription I got my copies always before they were available in the shops, up to the april 2014 issue. From there its always delivered at least a week after its available in the book shop. At the moment i'm in doubt if i will renew my discription at the end of the year.

Hi KC,
The vise is actual clamped on the table with 2 clamps. The smallest radius you can bend piano wire without the possibility to get cracks in the wire is equal on the diameter. The thickest wire you can bend with this tool is 4 mm. In video #4 i bend pianowire from 4 mm.
The reason i used M10 bolts is, if you look at the video you see at the other end from the in the vice clamped part also 2 treaded holes. these hole are positioned on the centerline. At the end where i bend the wire in the video the treaded hole are positioned on approx. 45 degr. this is done so you are able to bend right hand- and if you turn the in vice clamped part upside down you are able left-hand springs.
(p.s. I don't own an engineers vice.)

Today, maiden from mine Dawn Flyer.
Sorry no video, next time
Powered bij Robbe Roxxy BL 3545 - 10
Propellor 11 x 5.5 APC-E
Esc HK 60 Amps S-bec
Battery 3S 2200 mAh 20 C
Weight aproxx. 1700 grams.

Nice smoke, this could be used as smoker
Imo is this fire caused by lack of coolingair for the ESC .If you put in a new ESC, he will burn also within a short time. As I could see in the video the fuselage is coplete closed without any ventilation possible.Also you use a lot of foam to inside the fuselage to prevent moving from some electronic parts.

Thanks VA for the links.
The lower XT 60 connectors are for the ESC and the upper for the battery. As you can see it's very busy inhere, I had to drill a hole in the firewall to get the motorwires trough and have some free space left.
In this male connector goes the interupt dummy ( arming and disarming) connector.
For all who are also and will build the DFin the future, keep the tail as light as possible, to get the CG at the right spot i have to put 70 gramms of lead in the nose. probably this will be more because a plane can't fly without a pilot.

Hello all,
I'm now putting all the electronic stuff in my Dawn Flyer and use these XT60 connectors, they have a very tight fit. To put the battery in the compartment ( with the model tuned upside down ) and connect the the battery to the ESC you are very close with hands e.g. fingers to the propellor. After a flight you have to turn the model upside down again, disconnect the battery from the ESC. At this moment the ESC is fully armed and now your hands and fingers come again very close to the propellor. Does anyone have an idee how to avoid getting wounded by an accidently, at hi speed turning propellor.

As promised, some pictures from my DF build up to now.
Some details
Guide for the elevator control rod, I used 3 of them.
Detail from the wingdowel hole in F2 and the wingbolt plate with a M5 nut.
This is the motor i will use, Robbe Roxxy 3545-10 on 3S 2200-25C lipo battery.
Detail from the ruddercontrol wire tensioners, made from a quick-link, modified treaded coupler, m2 nut and a ferrule. ( I suppose it's the right name for it )
Detail from the closed loop at the rudder side. ( it's different from the detail on the plan )
Just above the wing sadle you can see I sanded the fuselage-sides flat to match to the tail end.
Possible some of the details are helpfull for other DF builders.

Hello Dawn Flyer builders,
I'm also building the Dawn Flyer and had the same problem with the differences in width from the body and the tail part. If you measure the width on the plan from former F4 including the wing sadle ( 99 mm) and the width from the body seen from above is 108 mm. In my opinion the fault is caused by the fact the top from the fuselage side is behind the wingseat 7 mm lower then at the leadingedge side from the wingsadle. This is not taken in account when the topview is drawn. I fixed it by making the first two cross members shorter so the tail part matches the width from the fuselage body.
will post some pictures from my build later.
