Just some fotos and video about my RC fast ride (but not fastest)

262 km/h test drive on airstrip

Przejazd 262 km/h  na pasie lotniska DOL

ARRMA Limitless V1 - belted drive main gear

5M belt - 35 pinion 15 spur -  diff 13/43

just testing concept of using belt instead of tooth gears 

Belted 8S car reach 228km/h in yellow GT Sweep P1L body  

now time compare result exact same car with new body "Project 908"  - photo below

more on body in link and description https://youtu.be/TS3CQOA92NU

All ride below always supported by PerfectPass of own design & program   https://sites.google.com/view/smoothrottle-jerry-perfectpass

max power was taken during acceleration on abou 80 percent throttle.

for keep MAX  speed on full power 390A 26V was enough during last 8  second to keep ~~225 km

full ride take 18 secosecond and last 10 second under full power

CONCLUSION 2022-09

• belt works fine

• can hold big power

• need faster motor 1100kv - maybe with 870 kV and 25V will catch 300km  (only dream .. hehe)

• need better tyres - this can blow up

• Need add cooling for motor wire and solder joint point  - to hot 

work in progress

UPDATE  2023-05

Now I will back to 800kv for compare car body drag

First onroad test 4S  - 141km -  less current draw

I can not show log from drive - becase I test  some special profile for throttle  - and result not yet available for public use

Second  onroad test 4S with GPS GSM-015

141km -  less current draw than on yellow body

third onroad test 8S

226 km -  unfortunaltelly  log for analyse lost :-)

========

2023-08 drag test on quarter mile

Tyres blow up at 147mph after 250250meters

Max power 21HP 569A 27V

... work in progress ;-) car ready for next ride
