Default RE: F-18 with EDF???

hi Carl,

Thanks for the info- it is useful for sure!

i fly the huckebein off of grass at my field...i.e. belly takeoff.

So my questions are relating to thrust etc. With 3s2p on the minifan and the fun 400-36, the kontronic website shows 28A at 9.6V and 540g thrust!

These are big numbers compared to the huck, which does belly takeoffs with under 300g thrust.

What is the weight of the model, without motor, esc and batteries please?

Also, do you know of any other power combo that people are using?

I was hoping to get away with a 3s 10C 2100-2200 pack, hence drawing no more than 20-22A max...which would put thrust at around 550g.

the kontronic site shows this:

V,I,WATTS,THRUST
7.6,18.5,141,394
8.7,23.7,206,501
9.6,28,260,580
11.5,38,437,841


So i figure that perhaps the 3s2p packs are capable of the 841 g thrust....isnt this a thrust:weight of over 1:1?

Basically what im saying is, do i need to spend that extra $200 to setup a 3s2p powerplant?...my experience with the huck has been that it flies great with about 0.5:1...even off grass...

I'm almost there-- to buying one....but, alas, no grey ones in stock at WBRC.

Tim.
