Does anyone know the speed record for an RC Airplane?

You want Class "F"

Quote from the site:

On September 11th, 1999, an official new world speed record for a radio-controlled model aeroplane was successfully made at Wroughton airfield in southern England, with an average speed of 254.5 mph (407.2 kmh). Previously, the speed record for an R/C model aircraft was 242 mph, set by an Austrian.

The real amazing thing about the Austrian record, was that it was made using a glider : the "Dassel".

Now that turbines are here, everyone seems to be concerned about LIMITING thrust (for safety), not going for records.

An experienced DSer can acheive nonstop acceleration until either his/her nerves freak out, the airframe reaches terminal velocity in the dives, or the airframe can no longer take the g-loads put on it , But to DS you need to fly very close to the hill and execute fairly precise manevers over and over again

As far as fast gliders you all need to watch some older f5B planes fly around (flying arc welders) pack about 20lbs of batteries into a <1 lb plane and dive it power off from spec height. Once they turn on their motors and spin 15x16 carbon folding props at 22k+ rpm (I have never seen this but her reliable stories) of planes doing 240+ flat and level

heck most entry level f5B setups will do 100mph pointed straight up to spec out

The fastest recorded speed for DS last time I heard was about 180mph. Theoretically you can go much faster and time will tell "how" fast people will go. The speed is limited by airframe strength under constant G's.
I witnessed the F5B speed run years back. This was an up and down wind, averaged run through a 200 meter course. The fastest run was 224mph. This was a direct drive sysytem with a 9in or 10in prop. The geared competitive versions of today are only good to about 175mph flat and level but indeed go straight up at over 100mph from launch. The battery weight limit for the F5B packs is 1100g (39oz) I believe or 24-CP1700's or 18 2400's. Minimum weight for the plane is 2000g (70.5oz).
Speed is good

At Superman 2 years ago a Bandit was clocked at 296 mph with a Ram 1000 turbine on board. There is a big difference between speed and affordable speed!

This is not a Prop speed record but if you can believe the GPS unit on this turbine, this guy is going 354.8 mph! This has been posted as a must see by Hammbone, but it is worth a second look! The catapult launch system is worth the look alone not to mention the sound.

Is this plane awesome or what!

Did you see the note under the pic??!!!
He had to take this plane to the Tzech Republic to fly it...air control in Germany does not allow speeds in excess of 250 kt under 10000 ft...
I once read an accident report where a Luftwaffe F-16 pilot was partially blamed for an accident because he had exceeded the 250 kt...

I'd like to see this one 'live' some time...
