Vladimir 's Snipe

[Pang]

Build log for Snipe.

Kits comes very complete with all hardware, lots of details are already done like pull strings threaded, manual was clear , experienced builders should be able to complete the build fairly quickly.



Weights

[Pang]

Wings

Aileron control horns assembly


Glue gf pads with medium CA, attach support pins, make sure they are able to move freely.


Test fit horns and pins, make sure no binding throughout whole range of aileron movement. Sand part of the horn if necessary.
Mix 15 min epoxy and fit the horns in. CA the pins down on wing alignment groove.


CF with thin CA over groove to hold pin in place


Peg

Mark and open up slot for peg. Dig out the rohacell and test fit peg


Glue in peg with epoxy as per manual.

[Pang]

Tails

Slots for the control horns are already marked on the tails.


Pen knife cut the slot and CA in the horns


Insert in spring for tails


Align vertical stab with wings , elevator attached. Glue down with CA then apply GF patch.


Hook on the pull strings as per manual

Finishing up this build thread

Fuselage. The fuse is follows the Blaster 3 style fuse with the boom extending all the way to the nose. This makes the whole fuse very strong and servos very easy to access.

Servos used MKS DS6100.


Battery all the way forward, i m using 1s 680mah. mark out where the servos start. Remove the stickers from the servos as they will be glued down directly


Align servos starting from the first one in front. Alignment follow as per manual. Horns used are smallest horn, 7mm from center. It provides more than enough throws.


Trim and glue the pushrod sleeve to the carbon support pc


insert the pushrod and make Zbend


Final fuse layout


Antenna placement below make it as parallel to wing as you can


I ended with no weight needed in front, CG 67mm, AUW 247g.

when you get bored of catching thermals, do some acros

1min mark, watch for the inverted handcatch turn around.

Power!

Nice...

Launch practice today.

Average ard 50m, peak 55m.
Surprisingly without ballast and with 30grams ballast launch heights about same. Need to work harder, some gorilla in USA just launched snipe to 90+ m.

Without ballast


With 30g ballast

Hi Pang,

What's ur AUW and cg?

I today flew at ohr average also ard 50m, highest 54m.
AUW 260g , cg 63.5mm, ballast 30g.

Yong

[Pang]

CG 67mm, AUW 247g without ballast.

Join us at CD field Sat mornings , more fun flying together.

[kok_yong2003]

Morning still in dream world . Haha.

My ballast I think is permanent in. Find very difficult to fly with the Auw 229g. Only able to fly in no wind conditions.

[Pang]

Without ballast, is your cg same? At cg 63.5 it should be able to handle some wind, prob up to 4-5ms.

I like unballasted more and normally won't use unless the plane is flying backwards in cruise mode, while others like sherwin prefers ballast. Add ballast for thermals not wind if possible. The main concern is can you launch a heavier plane well and do you want to give up a little sink rate to cover more ground (to search for thermals or get away from sink). I find less effort needed to launch lighter plane. Experiment and see what suits you best.

[kok_yong2003]

Without ballast cg is at 70mm. Find it hard to penetrate thought wind and most of the time can't get the plane back, even with some nose weight to cg65mm

And with ballast I can launch average 50m, without ballast only 45m.

Today flight at ohr

Nearly break the wing with hard throw. A lot of crack line needed repair
