The smoke trailing originates from a burning out controller...

That was pretty amazing.  Here is a direct link to the youtube.

That certainly is something.

From what I read on the web site referred - flying on 60 foot lines (approx) and weight is in the neighborhood of 40 ounces (1.2 to 1.3 kg).

Looks like a real handful and it would pretty expensive to fly if you where burning up a speed controller each time.

If you look closely at the photos of the plane you will see a trailing wire - it looks like it is currently set up to use a RC transmitter to start and control the motor remotely. I am sure that will be eventually replaced with a stand alone timer onboard before too long.

Good quality 8s and 9s battery packs as he is using are in the $250 to $300 price range (each) and with good care you might get a season out of pack.

cheers, Graham

That is the speeds we used to fly Rat Race at with two up.  Now you know why the event is dead. Not too many people could handle that speed.  I could see the pilot did have some problems at first.  DOC Holliday

That's exactly the speed I estimated they would do when the event was announced.   No real challenge if you don't mind burning down a system to prove a point.

Maybe it would be more interesting if the made 'em do two or three runs with the same equipment with a set time to recharge the battery.

Sort of like Bonneville Lakesters that have to make two runs so they can't blow the engine until late in the second run.
