30mm edf

does anybody know of a 30mm edf that is reasonably easy to find? price isn't a problem and i need something that gives more than 100g of thrust, i would like closer to 130g. and it need to work with 2s. or if i can get one to get over 150g with 3s. i know nitro's fan gets about that but i can't find where to get those. so any suggestions?

When you find one, please post for the rest of us, because Nitro's fans were the only fans capable of your requirements. Good luck.

Does it have to be 30mm? It is Much easier to get that amount of thrust with 40mm + (+33% more duct area also mean that you dont need to go that hard on the motor)

Do you realize what the current will be at those power levels?

The kp32 would fit your requirements. Derek of kpaero will ship to the US but I guess it might get expensive?

The general "problem" when things are getting to small is that it is ineffective (draws allot of current, get hot etc) and the difference getts to big (40mm is like 100% more duct-area than 30mm) If you go with 30mm, BUILD LIGHT.
It will be very fragile, but it will do the trick. Ratio and friction means everything.

Good luck with your build, Im building a 30mm ducted jet myself, but it will be verry light AUW about 30g.

ya i looked at all that and it would need to be insanely light and really fragile. hopefully i can make it work. it doesn't need to be very strong it would most likely be an indoor or dead calm flyer.
