Any EDF50 experts in here?

Hey guys i have never built or flown any EDF airplanes and I Just got one EDF50 in the mail today and was wanting to build a simple little plane to put it on or in, Anyone have any plans they can share, Also will my GWS 2 amp esc work with the edf or will it fry the esc? How many cells and what kind work best with this little guy? Any help would be greatly appreciated.
thanks
Jay

Hi

I´m no expert.... .....but I´ve been using the GWS 2A esc without any problems! 8x120mah gives a light airplane approx 2min flighttime!

I heard somewhere that maximum was 7cells... maybe 7xGWS250mah 2/3AA nicd would work.

You should probably try to build a airplane that looks like one... alphajet or somethin like that.

My Draken and Gripen is VERY hard to fly and just bearly flies using EDF50, but they do fly

Thanks Henket
I seen your post with he draken and i must say it is a nice plane but just from the looks i would say they are fast and more than i could handle LOL =) i was also playing with the idea of placing the edf inside a lightweight tube of the same diameter and building a non scale sabre or mig, I was going to either use sturdy board or a walmart glider for the wings, I would of course sand the thing down to a decent airfoil =) Oh I was wondering when you say 2 minute flight times do you mean 2 minutes with good power or 2 minutes then it has no power to stay airborne?

thanks
Jay

Some suggestions after the nice Mig-15 and F-86 that were built.

Try to build a Saab J29F Tunnan.

For pictures and info try the next link;

It should look like this (only one step smaller);

Jay!

2minutes is 2min in the air, including final glide back to terra firma! (only 3sek or so )

I visiting some friends next week... we´ve prepared a total of 8 EDF 50, and MANY servor and escs, and lots of white depron! maybe a B52!

or 8 Drakens

Kimble_Schmitz

Your Tunnan looks great!! we have the last still flying Tunnan at the F10 wing!!!

I figured that "Schubrohr" means duct in german?! right?
how does it fly?? fast? flight times?

Sorry, it isn't mine.
I didn't say so, did i?

Have you ever seen that Schuebeler site? It is great. And it is were i found that flying barrel.

It is a Midifan jet on 20 cells. So my gues is it has very high speeds and some real power.

As for now, i can not get my hands on those EDF-50 units. So i'll have to wait till i can build microjets. But even then i am not sure i would build a Tunnan, maby i'll just go with a clean Mig-17!

It would be nice to see a Micro Tunnan.
You could even make it tru to scale, becous you need a cheater hole enyway.

See ya

Cool i have never seen that jet before and i even have A jet book thats supposed to show every aircraft from the jet age LOL I did notice the powerplant designation # on the tail anyone recognize the letters? LOL Hey guys i do have a serious question, do you think an EDF 50 on 7 cells would fly this plane? here is the url to the post about it http://www.rcgroups.com/forums/showt...6&goto=newpost

Hi

that plane would probably fly well on a EDF50... the EDF50 is 10mm smaller then the other fan....

I got 80g thrust from the Unionfan (5bladed 60mm) using kyosho 300 and 10x110mah. it flew my Sonicblast very well...

the EDF50 delivers 86g on 8x120mah

EDF50:
8volts 3,5A
10volts 4,5A (did only try this for 2sek or so)

Do you have a link to the kyosho 300? I've been flying my sonic blast on a kyosho dmc20 and 8 270 nicads and am always on the lookout for more motor options I've also flown this plane successfully on 7 250 nicads, but it is better with 8 270's. Longest flight so far with a bit of throttle management was just shy of 5 minutes. Most flights are in the 3.5 - 4 minute range with some divey acrobatics (rolls and loops with a bit of a lead in dive, I think the undercambered wing is robbing a fair bit of speed)

the only info on the motor I have is this

http://home5.swipnet.se/~w-51614/el_flyg/pro_300.htm

same motor as my 300 motor, don´t know why it says 300 on it, it only preforms like a 280, atleast it does in my fan.

I got a 25Mb video of my SB, I´ll try to cut it down to get a couple of 2mb pieces to post here!

my SB flew only 2min on full power, and 3 with some rediced power. ...it was some 3-4 years ago.'

I just noticed that my B20 26s slips in the unionfan with ease
