Anyone here able to tell me which of these two setups is the best in EDF ? I'd prefer a 10S setup because of the weight and also because the chargers are more readily available but would consider 12S if there is a substantial performance gain.

Thanks,

Boo

you know this site is not to good for big electric stuff..
I think you would get a better and faster answer over at RC groups.com
don't know if they will let me tell you that...
but I have just move to large EDFs and that site is really up on the big electric stuff

I have two schubeler ds-94 .. one for a tam jet a-4 and the other a cermark f-16

my understanding is bvm and schubeler are both great setups...
I've been told the schubeler are faster.... but who knows...
if you want a schubeler Tam jets now sells them plug in play.. I really like the way tam sets them up
the CC 110 is in the tail cone... like bvms set up

good luck
Ron

Ron, you are correct. The Shub's are giving much better performance, thrust, efficiency, ect... Its a fact. Some are biased and will argue til the cows come home, but facts are facts.

So guy's, would a Schubler be the fan to install in a BVM F80 conversion instead of the BVM fan? I also like the 10S systems for the reasons already stated above but my chargers can handle 6 cell packs also.
Thanks Viper

ds wont work as well in stock bvm ducting, its a bit short and twisty. a Turbofan4000 would be more suited. its like a DS but with more pitch. by itself its not a faster fan than DS, but it would be a faster fan in that plane than a DS would be. and with higher pitch you can get higher watts faster with it than DS. DS doesnt wake up till 12s and up. For a nice turbo fan combo go nue 1912 1Y on 10s 5000 packs. should get you a solid 3200 watts in a light setup. Or spend the money and go vio which is a drop in.

Something else to remember is that while the DS94 can produce more thrust, @19lbs compared to 12-14lbs, it requires a 4" exhaust diameter, which is not possible with some 120 sized models.

i think the big question is the actual size of the plane. most times the exhaust is not the problem. In the big A-4 and F-16, both massive 17-20 pound turbine kits, they still dont have a big tail pipe, and yet we even went smaller, at closer to 3 1/2 inches for tail pipe. but the kicker is inlet size. EVF and most 5 inch fan planes are not really 120mm planes, there big 90mm planes. thrust it self is rarely the problem since velocity is more important in flying a plane well. And you can even have too much thrust, then you have to choke down the tail pipe so much you are sacrificing take off and loading up amps in the plane, cause choke the tail you raise the load on motor, which is fine if you take it into account when setting up power sytem.

Can anyone tell me where I can get the TurboFan4000 in the UK ? Or a sellere somewhere else who is will do export ?

Thanks,

Boo

Hi

For the samw watts, all the fans give the same thrust.

Current draw is another matter. The schubi is the most efficient, the bvm is by far the worst.

At 3000 watts the thrust is the same, the 94 is pulling 85amps, the bvm is pulling 100amps.

Bvm is heavy, almost a third more.

Hi,

Thanks for your replies Steve, can you tell me what the thrust and current consumption is like on the eTurbax ? This looks like being my joint frontrunner with the T4000 atm

Thanks,

Boo

Hi Boo

I am waiting for a slightly modified adapter shaft for my E-turbax. I suggested a slight design mod and I want to try that before I suggest results.

If you are adapting a 5inch inlet icdf model. The e-turbax will provide more static thrust and will be a drop in fit. The 1912 1y tf4000 combo is 20% lighter, will have current draw comparisons in RCJI very soon, or by e-mail if you get in touch.
