I had around 20 flights on it. I was in love with it. It made me push my self. The thing is that i was not doing anything real hairy when it had a dirt nap. Just some low rollers and got crossed up.....

He said "dirt nap"


Well it could be worse! Too bad you lost the airframe, but from what it sounds like you have the means to replace it. Maybe one of the local Aeroworks guys will give me a pull if I see them around- from what you guys are saying it really sounds like a great plane.

I'm about done. It weighs 29.5 pounds on a digital bathroom scale. I can't believe it. 3 ounce carbon spinner. A123s 2300's. 2000mah nimh on ignition. One tail mount rudder servo. Batteries way up in front of the gas tank. The gas tank is a Fiji water bottle. I built everything as lite as I could and its still 29.5 pounds. I hope it flies well at that weight. With out my receiver or receiver batts it weighs 28.5 pounds what the heck?

Awesome!!! it is a bigger plane then most 100CC'rs... it won't have stellar pullout from a hover on 100 degree days with a 100cc... but it is light on the wing for sure!!!

Hey Paul, You might be able to lose 1 lb. or 1 1/2 lbs with the Carbon fiber wing & tail tubes, and the CF Gear. Just a thought, Just a thought!

What engine and what exhaust? If you are at sealevel you will be somewhat ok. Showtimes floated pretty good and had awesome pullout with the 3W110, but I would still prefer 27 pounds or less.

Bodywerks, It's a DA-100 on in cowl mufflers. Also I took all your advise and went a little farther on saving weight. If I would have built this plane with my original batteries and stock tank and aluminum spinner it would have weighed 32 pounds. Unbelievable...

Most of us would not be able to tell the difference between your plane at 29.5 or at 28lbs. I had an AeroWorks 36% Katana that weighed a little over 30lbs, even with carbon fiber everywhere. The plane did not feel heavy. However, pull out from a hover was not good.

One word of caution, if you decide to start buying carbon fiber parts to help with the weight. I recently bought a carbon fiber wing tube for my new H-9 Extra 260. The carbon tube weighed only 2oz less than the aluminum stock tube. IMHO for two oz, it was not worth the cost.

If the airframe is fresh from where it's manufactured it might just be a little damp. Most of these airframes are made where it's 100 degrees and 100% humidity. Let it dry out for a week or two and re-weigh it. You might lose some weight.

Mine came out right at 27lbs. That's with a good digital scale.
The main difference is that I used a BME 110 engine on mine (2lbs lighter than the old style DA 100).
I also took out all of the balsa that made up the cannister tunnel (saved me 6 ozs), and I took out the dash panel wood in the canopy, and I used all the carbon parts (wing tube, stab tubes, tail wheel).
The carbon parts don't save a whole lot, but it's worth it to me because I fly at 5,000 feet.

My problem now is that my CG is about 3/4" behind what they recommend. I'm concerned that may be too tail heavy. I haven't flown it yet because I sent my 12X in for firmware updates, and I don't have it back yet.
