i think from memory its 750 watts on 4s and a 9 by 6 prop, but thats two years ago when i measured the numbers.

top speed maybe 85 mph , zephs are draggy, i put 1400 watts on it to hit 100 mph

recent vid ?
theres this one, a verticle takeoff (camera onboard)

thanks mat!

i am very familiar with that vid haha thanks


if you don't mind me asking- what was the 1400w system? i am currently planning something slightly similar on a 7x5 or 8x5 prop on a 1400kv inrunner on 6s. is that a big enough prop for the zeph in your opinion? did you just go a 10x6 on 4s?

the 1400 watt system was a hyperion 3025-06 on a 9 by 6 prop
, pulled 96 amps static, also ran well on an 8 by 8 apc sport - crazy setup tho, way to much power sounds like and air-raid siren when its blasting along

on the 9 by 6 and the 8 by it it tourque rolls quite a buit, drop to a 9 by 4.5 and the tourque roll drops noticably
