looks like there is plenty of volume for 70mm`s to work well. Just depends on how much power and weight the airframe can stand. 3kw would be easy to do with twin 70s if the airframe can deal with the stress and the weight. Should be fun.

Don, your 750w power system at 300w/lb should be awesome.

Does anyone know how many watts the stock rtf system in the video is producing?

I`m playing with using cut down minifan or HET rotors in a Hayeo 64mm housing for a system capable of very high efflux speeds on lower power.

Don, What a plane, I use to watch it do touch and goes when I worked for lockheed in palmdale california.
Questions:
Are you going to use 2 channels for the motors or put the speed controls on one channel?
How many servos will the esc. handle? I did not see any info on my 40a speed control paperwork on this.
Will you use a seperate bec.?
On some esc. you have to disconnect the red wire on one, and others you do not have to do this. What does your esc. recommend.
Got to have this bird.
Happy belated thanksgiving to all.

I am going to run them on a Y harness on one channel. The ESCs have 3 amp switching ESCs, and the ESC manual says they are good for 5 servos. It is listed at the bottom of page one on the ESC manual.

I will disable the red wire on one ESC before putting themonteh Y hrness.

I got stuck on Xmas tree duty as well. Weather is wind and snow anyhow so I have a few days. At least I got to maiden the F117 Saturday.

How does it fly with those odd outlets?? Slow cruzer? I haven't seen any video of them yet.

Edit, saw it on Bananna Hobby, looks like a nice park flyer.

Nice vid Don! The motor just sounds great and it looks like it moves out well!

Are you using a helmet cam? I'm suprised how well it works, nice to be able to hear you comments along the way. So often I've gone out to test something and want it on video but unable to get it due to no available help.

If by chance it's a FlyCam, check out their site here for the just released firmware download, it increased video quality a little and fixed the sound/video sync offset that has been present in the previous firmware versions. (I thought I detected a sound sync issue in your vid).

Mine showed up today just like the UPS tracking said it would. As far as I can tell this is exactly the same mold and hardware as the one Don has.

It came with retracts, fans, decals, battery box and radio compartment.

It`s a good fun size. Large enough to get some attention, but small enough to be easy to transport and fly.

CG Location

Don, just a heads up. Double check you CG location. My instructions say 78mm back from the front edge of the motor pods.

The small marks in the wheel well area are 5/8" farther back than that. The small marks DO NOT mark the CG location on my model.

On mine the measured CG is about 1/16" behind the back edge of the rx compartment.

When you get a chance check this measurment on yours. That should tell if they are out of the same mold or not.

Planning to fly my pusher prop version tomorrow.
