ok, testing complete

With 3s nanotech and 4.7x4.7 prop I get 250 watts and 25amps

Seems a bit lacking in power.. Maybe I need to swap out the het 3w...

What kind of watts are others getting?

Seems like a reasonable place to start, I was not much above that in my mild setup. It's probably not where you want to end up but it's definitely a good place to learn the plane. I would guess that you can probably get a good 105mph - 115mph out of that setup if memory serves me right.

If you want just a little more to start with you can go up to an APC 4.75 X 5.5 which will draw a few more watts and give you a higher pitch speed without changing anything else.

I believe that the 3W is 3000KV, I started with a 2700KV motor on a Graupner CAM 4.7 X 4.7 and it was a good place to start for my first 20 or so flights but I'm now running ARC 3850KV with an APC 4.1X4.1 (still trying to master the new speed), need more practice.

I'm running mine with ~300w. A different setup with 2s though. Using the 2W HET But as Birger said, it might be a good start. And then prop it up..

Anyone, with experience of lightweight setups in the Voodoo, reckon you could get the Voodoo to balance OK with a Mega 16/7 series motor (48 grams as opposed to 76 grams for the 16/15 series). This is with a small 1000-1300mAh 3S LiPo as a bigger one would kind of defeat the object.

I'm keen to keep it as light as possible and not too bothered about the outright speed given the small size. The nose does look fairly short and given it was designed around a speed 400 (same weight as 16/15) I think it might be a struggle?? Would place the ESC tucked up behind the motor at the top and battery as far forward underneath.

Although I obviously can't guarantee that it will work it seems to me that it should, as long as the ESC and battery can both be pushed right behind the motor (i.e. one on top of the other) and with the wing servos in the stock location you should be able to make CG.

Although the nose is short there is not much weight behind the wing, the tail moment is short and the fins are small, also, the elevator servo is mounted pretty far forward.

In my VooDoo I have this motor:

http://www.lightflightrc.com/HTML/pr...RC-28-37-2.htm

behind it I have either a 1600 3S 25C Nanotech or a 1350 3S 65C Thunderpower with the receiver above the battery, I then have the 40A ESC behind the battery and I have no issues making the CG, I actually have a 1/2" spacer behind the motor to ensure that the battery doesn't end up too far forward.

Thanks for the info.

I'm intending on using D47s in the standard location. I think I need to suss out a small thin ESC.

can someone measure the thickness of the wing at a couple points? Ive been flying a Rifle for a couple seasons and want to step up speed with the same power. just wondering where the different airframe would take the speed.

I don't have a Voodoo and can't give you any measurements, but I can tell you that damn thing is SLIPPERY and will definitely be faster than the Rifle on same power.

I have seen a Voodoo in-person and the wing is much thinner as is the horizontal stabilizer. It's definitely smaller than the Rifle in probably all ways that can be measured.

I need to get me one!

I've spent a while reading thro most of this thread for some research. Gone off the idea of the Mega 16/7 now and will stick with the tried and tested 16/15. Will start off with a small LiPo or maybe 2S, gives better options to grow into more power and speed once I'm comfortable flying the plane.

Just as a heads up for people using medium power 3S set-ups, struggling with squeezing everything in. This battery looks ideal:

Light @ 118grms for its capacity and a very slim 14mm thick.
