I`ve got a 500 grams (17,7 oz) 3d plane, how much thrust do I need, for hoovering and vertical climbing???

Thanks

About 700 grams of thrust will be OK. Of course you need at least 500 to hover, but in reality, you need a lot more to hover effectively. Even double the weight is good.

all you need is a Hacker a-20-20L out runner and you will be hovering half throttle!!! i have a charger rc cr1 that weighs about 17 ounces and it will hover at half throttle!!! plus you can buy the motor esc combo for about $110!!!! can;t bet that!!

Really? So we simply discount his battery, esc and prop selection?

If you can't give intelligent advice, don't!

Sed ... what they heck is your problem? Mikey is just excited and telling us what motor he has and how it performs in a hover. Sheeesh ... its RC for pete's sake not some mensa debate forum.

Wan - general rule of thumb is 1.5 times power to weight ratio or 150W per pound. You need a motor that will turn an APC 9x3.8 at about 8,000+ RPM or perhaps a 10x3.8 at about 7,500+ RPM. The Hacker A20 if you want to go outrunner is a great motor, so is the Himax 2812. If you want real all out performance for the 18 pz plane go with the Himax 2816 or Hacker A30, 25A ESC and a battery that can handle about 25A-28A continous discharge.

I got a Himax 2816 turning a 10x3.8 on my Fliton Prodigy (20 oz) and she will go vertical like a freight train and goes on and on and on ...

so as I see it, I would have a good setup if buy an axi 2808/24, and use my apc 10 x 4.7 prop, and 3sp1 kokam 2000 mah

It should give around 1036 grams of thrust

Wasn't trying to piss onyone off...just pointing out that there needs to be consideration given to more than just the motor selection.
