Also has anyone considered putting the aileron servos in the pod like the Predator ?

I see conflicting posts where the ailerons are pre-cut, and not. What gives?

hi,

mine wich was a binary 900 V2, was without precut ailerons, but there was a small line on the wing to know where to cut them

but maybe now they send it with precutted aileron?

install 3 servos in the pods (2xaileron + 1 elevador) must be quite difficult.
there is really few room to do it. but maybe you can do it.

with a little bigger pod, it would be possible to fit them in the pod on the side of the carbon tube.

just got a set of V2 wings. Not precut. I just tape a metal straight edge to the wing surface and use a new blade in a scalpel type knife to cut through the skin & the foam, being careful not to cut through the lower skin.

At the cutting the aileron stage. Did anyone find it strange that they're cut all the way to the tip ? I'm thinking about cutting mine short to give the tip and aileron a bit of protection.

Hey folks, what's the deal with glassing the fin onto the boom via the covering film, won't the film just lift straight off ?

Binary 900 V2 project

Giday all,

Im taking a keen interest in this thread as I like most others here either have a 900 or have one on the workbench / post.

Am just in the process now of getting together all the elec gear and wanted some clarification on what servos to use.
I should also point out that Im intending on making it a full 3-axis set-up with rudder.

Anyway has anyone used Blue Arrow D03013 Ultra-micro Digital Servo?
Specs are below:

Operating Voltage : 4.8V DC ~6.0V DC
Idle Current: 4mA
Running Current: 110mA
Hold Current: 350mA 4.8V
Speed: 0.09 sec/60º
Torque: 0.45 kg-cm/ 6.25 oz-in 4.8V
Speed: 0.08 sec/60º
Torque: 0.55 kg-cm/ 7.64 oz-in 6.0V
Rotation Angle: About60°
Size: 19.7mm x 8.1mm x 23mm
Weight: 3.6g/0.13oz
Wire Length: ~130mm

Although Im intending on running the machine using a 2C LiPo and voltage regulator stepped down from 7.4 to 6V my concern is that the torque may not be enough at 0.55kg.

Can anyone comment on that?
Cheers,

J.Take care with servos
the tork is impoortant bur the precsion of tje neutral point is crucial.

Thanks for that.. Ive previously looked at the Dymond 47 but sourcing them can be hard in Aus..
Is there any difference between the 47 and the 4.7S.. I seem to see the two names interchanges.

the "FS31" are the same as D47. i think

the D4,7S are not good for DLG application, they are faster, but less tork...


this one is nice also, on one little issue.
http://www.hobbyking.com/hobbyking/s...dProduct=14909

used in a small 1m DLG in France.
the user, say that the precision is VERY good, excellent neutral point and near 1 gram less than D47. smaller and lighter than the D47....

the problems:
a little play between in the "Arm" of the servo (but the manufacturer can easily correct it, maybe it's already done).
they are slow, but it's not a problem for a DLG
the consumission is quite high for a small servo like thie...

and for the fun... the 1m glider where they were used...

Cheers for that lebenj.
Some great info there. I had previously looked at those MKS Nukes but initially dismissed them due to there being a lack of information on them out there... Might have to revisit them and provide some feedback if I do go through with it.

I've also had my B900 v.2 in a box for close to a year now and finally broke it out and started building it. So far I have joined and glassed the wing as well as inserted the hard points and glassed them. Ailerons are cut loose and servo openings are cut out. I will try to complete the wing tonight and move onto the boom and tail surfaces soon.

I have chosen the 150mAh Losi pack, Futaba R6004FF receiver and 3 Hitec HS-35HD servos.

I decided to go with the HS-35 servos after they got glowing reviews over in this thread:
http://www.rcgroups.com/forums/showp...&postcount=609
And they have the added bonus that they practically fit entirely within the wings, let's see how they turn out. I had to wait over 3 months for them so let's hope that they were worth the wait.

I'm new to DLG, this is my first one so let see how I do

Re: the HS-35HD, check out this thread for some discussion. There is a photo comparison of the '35 and the D47 in post #19.
