Hi
That all depends on the power setup and size fans
Right now im still in the concept phase but was thinking of using 60 mm or 90mm Fans
Scale between 1/12 to 1/8 or 1/6

This is going to be fun to watch. How much are you going on scale look and how much on scale operational system. Are you going to use two fans for vertical lift and one for thrust?

Hi Tyler
Im going to try and make as accurate a reproduction as possible in balsa and ply laminates
Including the movable rotor door covers and the internal ducting for forward flight
As i stated earlier a very ambitious build
Take care dear friend

Hi John
Thanks for the vote of confidence, Im going to need all the help i can get for this one
To start i ordered this to use as a reference, should be quite fun to assemble as well
http://www.anigrand.com/AA2007_XV-5.htm
Will start the build thread by building this one when she arrives so i have some thing tangable besides the photos, 3 views and blue prints to go on
Take care
Yours Hank

Oh boy! You arent kidding about an ambitious build!

Id recommend you use the largest diameter props that you can fit in the wings for the heavy lifting. Mostly because edf's just suck big time for generating thrust. Also, thrust increases - and decreases - as the 4th power of the diameter and only the third power of the rpm of the prop being used. So for pure lifting, diameter is your friend more than rpm.

I think its going to need to be fairly large so you can have a wing thick enough to try to hide the mechanics for the fan/prop drive. Are you thinking of a 90 degree gear drive system for the wing fans or a belt drive or?

This will be very interesting for sure.

Good luck!

I think I need a signature.

That is a serious challenge Hank, not only to build but to fly as well. I wish you all success my friend.
Watching with fingers crossed, good luck!!

Hank, looks interesting, thank you for the link to Anigrand, they have some very intriguing planes, I will have to study them carefully.

I would think of some kind of gyro control system, might help, for side to side stability, and maybe front to back.

Good luck with this one.

The latest I've seen for doing something like you want to do.

Wow!!! That is a huge project. You will need 80-90 mm fan for sure. You best use a KK multicontroller over gyros since they have not proved out very well. I am still trying to determine which controller to buy(lot of cheap foreign ones are no good) for my VTOL transport. And mine is a transport.

Good luck!!!
