AeroSports;

Would you consider making one set of conversion kit to sale. I like your conversion and would want to do the same. Thanks.

I don't have the ability to produce kit. it is pure a fun project. however, if anyone who owns a machine shop and like to produce it, I don't might sharing the info.

the weather has not been good, or hasn't had time to do more. Have not been able to get the video from those who took when I first flew. I will push them.

I am flattered to receive compliment from someone from bergen. thanks, Chris. I always admire your works.

Man, that is impressive. How do you control Yaw on a mchine like this? It looks like the rotors are belted together or I'd presume (in total ignorance) that differential torque could do it, but... I'm just boggled man how you could do something like this. Very nice job.

E-conversion or Nitro
Wondering if video is available yet to compare to the many nitro videos that are out on the web. The videos of nitro Chinooks on the web show some very nice flight but I'm wondering how the electric version (that you have created) fares in comparison.

I'm planning on building up an MRC CH47 in the next month or so and would like to see if I should try to go electric as you have done or install the .50 engine.

Any advice?

On dual-rotor birds like the Chinook here do both rotors have 2-axis cyclic control?

And what sort of swash setting do you use in your tx??

From what I understand, the new hirobo has an electronic mixer on board. You set your TX to be a single servo swash (mechanical) mix and the mixer sends the correct info to each rotor.

Look here:

Looks like ccpm on both ends.

Thanks for that link. I'm fascinated with the mechanics/avionics of this machine.

I'm wondering -- You're in a hover with this bird. You input left rudder. Does the 3-axis gyro convert this to left cyclic on the front rotor and right cyclic on the rear?

Again, in a hover -- You input forward cyclic on the tx. Does the bird pitch forward in order to move forward or do both rotors deliver forward cyclic simultaneously?

Are there parameters of adjustment on the gyro (like gain on a conventional tailrotor gyro) that permit it to be tailored to a particular flying style, or to lessen the 'help' it gives you?

Again, this is just from what I have read,
scenerio 1: both swashes move so the bird will piro at it's center.

scenerio 2: not sure.

There are adjustments to the control box. I beleive ther are three gyros in it.

The two swash plates (three point ccpm ) are linked via a special control box which is connected to the reciever and a three axis gyro , for forward movement both swash plates tilt forward , backwards they tilt back and sideways they both tilt left or right . Rcadd1ct is correct in saying that rudder is controled by both swash plates , they move in opposite directions eg to turn right the back swash tilts to the left and the front to the right

If you look closely at the photo the box behind the rx battery back is the gyro and the box above is the control box . hope this helps CT

Wondering if anyone has or could make a video of the hirobo Chinook in FFF with some turns thrown in that they could post.

I have had one for about 2 months and love it but don't find that it's extremely stable in flight.

There is a video on the internet of a Chinook doing amazing figure eights but if you look closely, you can see that it is not the hirobo model (most likely a vario, or at least the body appears to be). I would like to see if the hirobo can do the same in the hands of an experienced Chinook pilot

Have you seen the video I posted ? I find it very stable apart from collective control , It drops like a stone due to the wieght of the batterys , it does tend to rock to and fro a bit but thats the pilot not the Heli .

Yes,

I've seen your video and I think it is excellent.

Have you taken it to an open field to really let her go? That's what I'm curious about.

I have not had the confidence in the stability of this helo to really let her go in FFF (obviously pod-boom helo's are pretty easy to let them rip across a field, but this one is different).
