Vibration damping
http://diydrones.com/profiles/blogs/vibration-damper-for-gasnitro I had read about issues or concerns with vibrations and gas/nitro powered planes so I come up with a vibration damper assembly made up of 2 fiberglass plates separated by 4 foam ear plugs that I cut the tips off and glued to each piece. On the lower board I also mounted my receiver and the airspeed sensor.

I flew this in a 66” Decathlon power by an O.S. .70 four stroke and had no issues at all with vibration – at least as far as the APM is concerned. I tested the unit in stabilize mode and RTL both worked flawlessly! Late into my second flight while in manual mode I was doing a few touch and goes after the third one I was on the downwind leg and everything quit working the plane ended up rolling onto its back and nosed straight into the ground. The plane is a total loss however after stripping all of the parts and performing a few checks on the APM all of the really cool stuff is still working perfectly. The vibration mount had to help some but it does show the boards are fairly durable

The best way I have seen sofar to get rid of vibrations in a Nitro or fuel palnes is to susspend the APM on the CG in the air.! so for example use the '''ArduPilotMega lazer cut box and dril a hole on each side of the mounting plant then span a rubber band from each side of the box to the closest serface in the plane then if you tied it very tight and the APM board it level in the plane take tissue paper and support the APM box all around it in the airframe. it looks weird but it works very well''' - http://diydrones.com/profile/JohannVanNiekerk

Use the http://uavfactory.com/ Aerosonde type frame which allows the motor to be mounted at the back onto a vibration absorbing material.

For me Silicone Foam works the best for eliminating any vibrations. I have my APM mounted inside of a semi enclosed servo box, the kind higher end digital servos come in, with a 0.25" thick piece of silicone rubber foam between it and the frame. I am using double sided foam tape to adhere the foam to the frame, and the APM box to the foam. Vibrations almost completely eliminated. AC2.025 is working great though. Yaw now resembles the yaw we had in RC2. Alt. hold is working excellently, 1-1.5 meter drift up and down. Loiter still overshooting a little. I have made some PID changes and will be flying again today. Great work!

On the front page there is a jpg link to a commercial quad drone that attaches the four arms of the quad to the drone enclosure with a rubber block.

http://www.barnardmicrosystems.com/L4E_inview_gallery.htm mounts two engines on vibration absorbing blocks that are attached to each wing.

Aeromao frame
Uses pilon racer frame, attached to a pod. Smaller pod will result in higher speed but less endurance.

Ideas
Build a d5f pylon racer but make the body larger and attache small dome camera to underside, that can retract back into the fuselage when landing. Electric pylon RC racer that flies at over 200km/h. Or place the electric motor on top the fuselage,wing structure and form a round dome in the nose of the plane, merged with the fuselage and the camera inside at the front.

25hour flight across Atlantic on 1litre of petrol. Large inverted V-tail design which gives it stability in high cross winds, where other planes won't work. InfraRedLeds or ThermalImagingCameras are built into the air frame for long range night vision. One of the big advantages in favor of inverted V tail designs is its stability in cross wind situations. For an example when hit by a cross wind gust on landing, the inverted V will cause the airplane to pitch up as opposed to diving into the ground. Mounting of the engine at the back of the plane allows for reduced vibration possibilities. Place a vibration absorbing material between the frame and the engine. Vibration tends to saturate the IMU RateGyro2's. http://www.mini-imp.com/tail.htm

This feature consist of four thermal sensors and some intricate circuitry that can tell the difference between the ground and the sky

Czeck drone frame with GIMBALL
http://www.leteckafotografie.com/aerialvideo/index.htm

http://www.leteckafotografie.com/aerialvideo/plane_eye.htm This little plane is very powerful. Adding a light cradle camera to it with a little video transmitter makes it ideal for monitoring what is happening on the ground. Have you ever get yourself in a traffic jam? I guess a lot of us always wonder where the line of cars ends. I would take this video plane from my trunk and within 5 minutes see. I can imagine hundreds of applications where this handy model plane would find itself useful. It is small, light, wind proved and soft (if it is accidentally going to hit a person). I mean I would not like this to happen - this plane could be pretty fast. Speed of 160 km per hour is not a problem for our set- up. There are tuned set-ups on the web where this plane can reach speed of 240kph.

http://www.leteckafotografie.com/aerialvideo/gimbal.htm When using KX191 colour and night mode CCD camera on little planes, I noticed that each time the camera is pointed sideways, the large camera body works like a rudder and the plane begins to steer. I made this carbon fiber case to house the camera in it. The unwanted steering stopped. Also the aerodynamics is better. There is also video to see how it works on FunJet in flight. The gimbal with servos and KX 191 camera, weights 100 grams.
