Small Micro Quad only 11" across @175g(The Ripper)

I am getting ready to build a DIY Quad using a Gaui GU-344 gyro from a 330X quad. I am shooting for a light powerfull quad for acrobatic sport flying not an AP platform as you would figure by the size. Quad will be 11" across and it will be 10" motor 2 motor. Any veterans out there that want to "chime in" Please do. Here is a list of parts I will be using.

(4)Trex 250 booms
(4)Trex 250 Boom Mounts
(2)4" Square CF 1mm Thick
(4)Turnigy Plush 6a ESC's
(4)1811-2000 Brushless Motors 2000Kv
(4)6" 3 Bladed Props(2 rev & 2 reg)


Motors will be mounted using Zipties and hot glue to save weight.
I am figuring about 200g total weight without batt.
Batt will most likely be a Hyperion 45C 900mAh 3S @ 89g or a Outrage NRG 35C 1300mAh 3S @ 123g.

Just got the frame built. It weighs 50g without Landing Gear. Still gotta put a big hole in the center for the wires. Gonna mount the motors next.

Pics of the frame w/motors mounted with zipties and hot glue. Looks like it will come in at about 160g total without batt. I will have the exact weight once its done.

decided to just solder all the ESC/motors instead of using bullet connectors but that will prolly change. Was not sure if they would get here today so stayed up late soldering last night. Here are a few pics of the finished quad. I just drilled holes in the CF and ziptied the wires for now.

Currently building a tri with similar specs, but 8" motor to motor using similar material for the frame

One way to save weight is by using "horizontal stabilizer support" and screwing the motor into it


I had quite some luck on this one, the motor holes spacing is exactly the same as the support holes spacing
If it's not the case for you, use a narrow band of CF attached to the support and extending it on both sides, light and easy

The other advantage of this mount is that you can tilt the motor around the arm or move it for easy adjustement

WOW thats some sweet flying and that quad ha mad power. It sounds pissed off. Hehe. Looks like I'll have to try a quad with those motors. Looksmlike they are on backorder at HK and Nitro Planes wants $10 more for each motor. Not sure if the real hacker motor is any better but they is like $38 each. Thanks for the vid and breakdown of equipment used.

pretty cool, is it setup + or X?
+ seems more aerobatic, or is it the same?

Tony,
The hot glue will melt with the motor temps. Ask me how I know this... Make a simple pinch block mount out of your favorite light material instead.
Cheers,
Jim

Interesting, I have 4 of those same 10 gram motors coming and 4 6A plush escs.

My build will be very light. though with 5x3 gws 3bladed props, 6mm square carbon, and 8" across.

I am gonna use a light small batt so my flight times will be short. I will check the motors after my 1st 3 mins of flight to see if it gets soft or melts. I am using zipties also. The hot glue is just to keep it in place. I would have had it done by now but waiting on bullet connectors for the motrs/ESC's. I was gonna direct solder them to save weight but decided its not gonna save alot of weight anyway. Thanks for the warning cus I would not have thought to check the glue for melting. I should have the bullets Fri so looking at getting it airborn this weekend. If it flies I will get someone to shoot a vid of some sport flight.
