Build Log

Hyperion EXTRA 330SC 20E 3D

Hi guys,

Hyperion's newest addition to the 3D and scale market has just been released.

I'll be doing a build log on the 20E and will cover some of this new 3D monster's numerous features.

Some brief info:

The 20 E has a 41.5" wingspan with 370 square inches of wing area.

It's made to accommodate Hyperions Atlas DS09 servos. I'll be using 3 HP-DS09 SCD's (elevator/ ailerons) and a DS09-AMD for rudder. It uses a 35 amp ESC (Hyperion Atlas 35A LBEC) and the upcoming Hyperion ZS-3007B-24 brushless motor (an absolute jewel of a motor.)

In terms of batteries, I'll be using the Hyperion G3 1600 VX and 2100 CX, recommended are the Hyperion G3 1800 up to 2200.

The build is very, very simple. Please note I will not necessarily cover the build in the same steps as the manual, but either way will work just fine.

A link to the Extra 330SC 20e box label, in 1200 pixels wide.

Price of the 20e is $169.95, with Zs3007B-24 motor included.

Hi Allbread, sorry mate I don't know, the 90E won't be out for another few months.

Hi Everyone,

If you take a close look at the fine print on the large box label pic, you will see that there is a disclaimer stating that the 330 20e has a flat-plane tail surfaces to keep the model as light as possible. We had a Chicken-egg problem as a final 20e wasn't ready in time for photographing for the box label (decals were late), but we did have the 330SC 35e. The big pic in the middle is actually the 330SC 35e, and it does have the airfoiled rudder and elevator. I photoshopped those to make them look as "flat" as I could, but the junction of fuselage and rudder still gives it away...

Otherwise, the two models look pretty much identical... The smaller pics are all of the 20e, fyi...

Some pics showing the SC in in the box, un-boxed and some others.

The foam it's wrapped in is very protective- and ideal for over exited individuals who have to tear parts out rather than use scissors.

I always open up all openings in the fuselage before really starting assembly. You can choose to use a sharp hobby knife or soldering iron- I use a soldering iron because it seals up the covering and is generally just easier IMO. Make sure to open up cooling holes in bottom of fuse, CF spar opening, wing servo opening, anti rotation pins, rear servo pushrod exits and wing screw.

As a precautionary step, you may also choose to run over the joins on the motor box with glue. I always use carpenters glue in favor of thin CA, but both ways work just fine.

Next step is hinging the ailerons. Very simple, two drops per hinge per side.
-Make sure to move the aileron up and down until you can get the full throw the bevel allows before dropping CA into the hinges though. Sealing the hinges helps in surface efficiency and high alfa flight, but is completely up to you. I will seal mine a little later down the track.

Onto the control horn.
Firstly locate the two larger control horns out of the accessory bag. I Roughen the base with sandpaper (this lets the glue "grab"). I've always been happy with CA, slow curing epoxy and Poly Urethane- but I decided to go with polyurethane for the Extra.- If you do decide to use PU- drop one drop of water into each hinge slot, lightly coat the control horn base's with PU, place a bit of PU in the hinge slots, and simply push the horns into the slot until it seats all the way. The bond will be super strong but PU sets slow so the wings should be put away to allow the PU time to set.

Model looks nice. Looks like there's alot of new stuff over the older models.
Does anyone know if the larger models will have Ultracoat covering on them.
I can see using the cheaper stuff on this model.

Is the landing gear and wing tube aluminum or carbon fiber? Are the wheel pants fiberglass?

Hi Jay, wing tube is carbon fiber, landing gear is a high grade aluminum and wheel pants are fiberglass. I'll probably move onto landing gear next.
