Update on project.
I have teamed up with www.multirotorshop.com.au who have some of the latest gear to test including the new Flycolor 6s ESCs
Best results were achieved with the ZMX2206v3 2300kv motors from Silverdrone.
Am trying to get F80 motors to compare thrust against these.

The noise made on 6s has to be heard to believe, it's really incredible.

3D Printed Speed Frame


I will most likely be printing the frame out of COLORFABB XT-CF20 CARBON FIBRE FILAMENT
https://www.3dprintergear.com.au/spe...-filament.html
the arms will be reinforced further with a 10mm cabon rod.
Here is a render of the frame parts.....

Funny that now we have 2 in the race for it! Lets see who can get there first! :P

I beliave we will be competing with the same motor.. (ZMX2207?).. so its good competition.
I will point out 2 things,
1. all my work is open source and shared,
2. He who laughs last laughs the loudest.... LoL

Flow simulation.......... PASS


The latest design will be 3D printed soon.......

Watching with interest...

I reckon you should be shooting for 300kph! Need to look at the best prop for pitch speed rather than focus too much on thrust imo. Have a look at the F5D pylon racers.
Be sure to run 28mm spinners!

Thanks TIM, very much appreciated. Seems there is less interest than I thought.
I agree.... static thrust is NOT a good measure of top speed. Like gearing on a car you can not measure top speed with just torque data.
In simulations we are finding we need VERY high velocity thrust (350kph+) in order to reach world record speeds.
While I would love to produce a 300kph+ machine it seems by all calculation even 250+ will not be possible with todays tech.
The recent record is actually very closely just under our calculated speed. Lets see what our results bring in the next few weeks....

I'm watching with great interest, but I lack the knowledge and experience to add anything useful, there may be others in a similar position. Its not very often we go for a world speed record

Update......
Still having some issues with the 3d prints warping

continuing with motor/esc testing on a Kraken frame
Have not found any ESCs to live up to the 6s test yet.... of the ESCs tested some lasted 0 flights and none more than 2 flights.
Running all tests with 220uF 50v LowESR cap
all tests ramp up from 4s to 5s to 6s
here is the KISS30A on 5s
