Build Log

Pulsar 2008 2m


Yesterday I received my red Pulsar 2008 from GIRmodell in Germany. I will be doing a small build thread as I go along.

First impresiion of the build quality is 1st class. I also own an Ava and Ava-E from Vladimir, and I must say that the Pulsar is at least as well built, maybe even better.

I put all the parts on my scale to check the weight:

wing, centersection: 106g
wing, right tip: 62g
wing, left tip: 62g (!)

rudder: 14g
elevator: 20g

boom: 22g
fuselage: 44g
accessory pack: 16g

Total: 346g

I have not decided on servos, motor or esc. But might opt for the following:

Hyperion G2213-16: 66g (250w - 300w depending on prop)
Jeti SPIN 44: 40g
10x6 CAM folder and 30mm spinner: 35g (guesstimate)
Servos:
Hitec HS-65MG x 3: 39g
D60 x 2: 18g
3S 2100mah batt: 194g
JR 921rx + 2 sat rx: 26g

Total: 764g (26 oz)

Roto...

I had a 2006 Pulsar for about a year and a half, and truly enjoyed flying it. Actually, it was my first electric sailplane, I really liked the introduction it gave me to the world of electrics.

She would thermal nicely, penetrate well if need be, and was just a great joy to fly. Enjoy!

I have now ordered the Hyperion G2213-16 along with a Hyperion Titan 30 amp esc. Servos will be HS65MG and 65HB. The wingloading will be in the region of 24g/dm2 (8 oz/sq in) and very similar to my Ava-E.

Some may wonder why buy this model when owning 2 Ava's. My reasoning is that I have the possibility to fly from my doorstep. But my Ava's are to big as the landing area is very narrow. My Easy Gliders have served me well in this respect. But I really wanted a high performance model, and I acted quickly once I discovered the Pulsar 2008

I'll start building as soon as the parts arrive. Stay tuned!

HI RoteEddie,

I've always wanted one too. We will be looking forward to your build thread, and maiden flight report. Best of luck to you.

Similar reason for me - smaller model to fly at local fields where I would never consider putting up my AVA or other 3m models.

I'll watch with interest. I almost sold my Pulsar, but it's so well built, I have to assemble it!

Hi RoteEddy,

I, too, am very much looking forward to your build thread. Will you be able to include photos ?

Sorry for the delay. I'm very busy being a father these days for my 8 month old boy. Looking forward to the days when he can share this wonderfull hobby

Anyway, here are some pics:

I left out the tailparts, but the rest is present.


Remote receiver installed in the center panel. I have not decided if I will install a 2nd remote.


Details like these pins are a sure sign of quality.




This is the view from my house and where I intend to fly her

Today I got the Esc, prop and spinner. The spinner came with no middlepiece(whats the correct word), so I had to order one. Hopefuly I can start building tomorrow.

Andy W,

I am going to start my Pulsar 3200 build shortly, and like you have a 2.4Ghz radio. I was thinking of doing the same, mounting the remote rx in the center panel. I have been thinking of using some RG174U wi-fi cable to extend one of the antenna of the remote rx and extend it to the other side of the center wing panel.

How did you attach the rx in the wing panel, did you glue it in, or use double sided tape?

I recommend you place the main receiver in the fuselage and drill two holes to extend the whiskers to the outside. Coat whiskers with silicone to protect them.
Satelite goes via extension cable through the fuselage tube to the tail fin and gets embedded in the fin under the covering.

This way you have a good working installation and no need to disconect any receiver related cabling when removing the wing.

Here's some pics... Note, the whiskers got a good coat of silicone after installation and the satelite was placed inside the fin after test flights had confirmed that this worked flawless.

Thanks test005, that's another good option. I am concerned about the C of G with mounting the rx in the tail, and I want to keep the tail as light as possible, but it may just work out.

What did you use for the extension wire to hook up the remote rx to the main rx? I will be using a AR6200, but it hasn't arrived yet so I don't know the weight of the remote rx, or length of wire included with the remote rx.

I am planning on doing what you did with your main rx, and place the whiskers outside the main fuselage body.

The remote RX is quite light and for cabling I ordered Spectrum original 36" extension cable they have as an option just for the purpose of installing the remote RX further away.

I have flown @ 1800 feet altitude with this set-up so I think it works just fine.
Remember to coat the whiskers in silicone once you have them out the fuselage, this will protect them from getting bent in transport etc... To coat them, simply open the silicone tube and slide it over the whisker all the way until the tube hits the fuselage. When you pull the tube away, the silicone has a nice even coat on the whisker and should hold on to the fuselage as well.... hmm, did you understand this?
