I am bringing the pictures over so that the FG community can see it, for anyone on FG that is not on FB.

This looks amazing!

We need to see a flight video!

wings and stabs

now I see how it all works.

the wings do not have a fix root trailing edge.
the aileron will abut the fuselage side.

Very innovative.

on FB, they post that the wings weigh 1500 grams and that that is light.
1500 gram wings with no servos in them, ready to fly, equates to 3 pounds and 4.8 ounces.

I don't believe that is really very light. I want to say I have wings on a Kam Aero that with servos weigh under 2.5 pounds each wing panel. With the servos, linkage, everything on, ready to fly.

I was curious so I weighed a wing of my new 104 EF Extra V2 and the all up weight RTF is 1110 grams.

Composite airplanes have always been a little heavier... the big difference is where is the weight... is your cam aero wing heavier at the tip or at the root? Being in composites and building composite airframes, the weight is uniform across the whole wing. There normally is not one spot that is heavier than another.. that eliminates stress and makes an airframe that is more durable for a longer life. Wood wings will fatigue at the heavy spots and cause stress under heavy G load. While in a year or 2 no big deal but a composite airframe could have a life span of easily 10-20 years, of hard sustained flying only needed things like hinges replaced.

I could not agree with you more Carruthers.
I am just interested to know the total weight of that airplane.
I had the opportunity to see a CARF Extra at a contest, and when I picked it up by the tail, wow is all i can say. It was the heaviest tail on a 40% I had ever raised. I am talking about super heavy. Some people say, weight is not an issue. I beg to differ.

My first 40% aircraft was a 40% 3W Extra 330, and with a DA 170 and stock mufflers, that airplane weighed 52 pounds.

I do not want to sidetrack this thread or make it seem like I am anti-composite airplanes. Just sharing my experience.

Not sure what you know of andres the owner of CARF, but he is hard on airplanes here is the post flight report... the first line makes me think he possibly broke it??

Everything felt great.... until the pilot ran out of talent.

But we are so happy! The concept couldn't have worked out better. CG is spot on with even the longer fuselage and its extended tail moment and the control efficiency is almost scary. The engine is so powerful on that light weight airframe - An average pilot can barely scratch the potential of its performance, keeping up with the roll rate and such. Time now to treat this beast with a good workout by the "TEAM" :-) Stay tuned.

"Breaking the laws of physics" has got a new dimension: CARF-Models Extra 330LX.

Wingspan 305 cm
Weight 18.4 kg
#ZDZ 195 "Champion"
#MTW TD130 canisters
#SAVOX 2290 SG
#Powerbox Mercury

This is not a new idea as it was done with Byron Originals back in the 80's. It was for a different reason, plug in thin foam wings for jets that worked OK, 1\5 scale warbirds with flaps and ailerons that had some issues with long torque tubes that had flex .

A 40% 120” full composite plane at 38-40 pounds will be something special. I hope they post some flight videos soon!

DA 215 dimension width are very close to the 170 DA with the option of slanted in spark plugs like the 200 or straight in like the 170 . Guessing it should fit .
Amazing innovations from Carf .
I hope there is some supports for the carbon rod to each elevators so they don't flex under high g-loads .
It would be interesting to see if they are releasing a 35% version 330LX .
