Components:

DLE-120, ignition, sparks, muffs, throttle servo and linkage, hard switch, ignition battery, Rx batteries, gas prop, fuel, 7 control surface servos, AR12 channel Powersafe with 3 sats, 7 servo arms, and extensions... 11.54 lbs.

27.69 lbs for the EF 104" Extra 300 V2 is about as light as I've seen.

I don't have the difference in weight between the DLE and the lighter DA-120.

But I agree that there is a lot more effective wing area on these planes than the published wing area suggests, so they will tend to float. For me, the important thing is the acceleration, which seems nicer on lighter planes.

I don't know first hand but I'm hearing that the EF 105" Slick 580 comes out of the box just about 0.35 lbs heavier than the 104" Extra.

Glide ratio has a lot to do with wing thickness too and there is a big difference between most of these planes. I know Andrew spends a lot of time on his wing design and although the 105" Laser is heavy, I've never heard anyone complain that it flies heavy.

Sorry I meant GP123 or DA120.

Hi everybody, can anyone, please, make a flight characteristics comparison of 104" Laser EXP with 104" Extra 300 v1 and 105.5" Slick 580 EXP? I flew with both Extra and Slick, know them well, and now I'm thinking about Laser. Thanks.

You can keep an eye on the Tucson Aerobatic Shootout next week: there will be 4 pilots flying this model in Free Style

- Spencer Nordquist
- Bryant Mack
- Yuhei Suzuki (Japan)
- Toru Kasai (Japan)

Florida 3D: Spencer Nordquist (3 min 26 sec)

EF 104" Extra 300 V1 = 17.79 lbs with Pilot X (115g), instrument panel (65g), LG fairings (35g), SFGs and shims (100g), so potentially 17.1 lbs if you're willing to gives up things that may not be included in other planes.

Kavan wheels can also eliminate 7.4 oz.

EF 104" Extra 300 V2 = 16.15 lbs with similar components including the stock 4.5" 358g wheels.

The Skywing Edge 540 V2 in the video is 16.23 lbs.

The 3DHS Edge 540 V2 is 16.45 lbs.

The 105" AJ Laser 230z is 17.83 lbs and I'm not sure if a V2 is in the works.

I'll have more info about the 103" AJ Slick in a month or so.
Thank Aeroplayin

I hear that a lot and should just buy one, but I've been hoping that someone would break down and make a 35% Laser with the Leo Langenslager and Jim Roberts cowl version in the Blue and Yellow scheme. I'm a little over the red version since there are so many around now.

How about we just scratch 35% and get a bigger trailer?

40% is the new 35%

CARF Extra 330LX @ 38lbs , new Slick also stated @ 38lbs. Now we need a 40% Edge in the same arena.
Wondering how many high G maneuvers the 40% balsa/carbon plane can handle. Very curious to see how the new slick is designed.

It's with the carbon composites we already hashed through here and we'll know more once Jase has the opportunity to do what he does. This plane is phase 1 of prototyping and not the final design.

Years ago I worked with one of the three main kit builders on a 35% project and learned a lot about light airframe construction. The way the 40% (126" Extra 300) was built to 36 lbs dry with a DA-150L was still ply, balsa, and sheeted foam, but the hardware we use to keep the wings and stabs on was a configuration I'd never use for a Freestyle or 3D airframe in that size today with today's maneuvers and power loading.

Putting a GopPro on the main wing looking back to the one stab is a really good way to monitor fuse torque through some the high-G maneuvers and a good way to sell airframes, IMO. Back then, there were no ARFs that could manage the same rigidity as the kit products, but times may be changing. Watching this plane fly has me thinking about another paradigm change in large scale construction.
