Throwin' a bone, but read this quote from post #33, "I've flown other "ultra" light 50 size machines and did not like it at all...". That was my T-Rex 600NSP! Yeah, shes got some interaction problems, but she runs goood! While my N9 is in pieces, the nerve!....
I shot two videos of the canopy-less N5 for him today. Matt mentioned this UK forum. I had not seen it before and when I checked it, I thought I might re-direct. Videos might pop up there...

Interesting comments posted by Matt Botos on the link posted above:
- Main shaft position - I put the servos in front of the main shaft for a few reasons. First, the N5 was designed to accept larger main rotor blades (ie.. 620's) The increase in boom length affects the CG significantly. Also keep in mind the fact that we will most likely be flying OS55's in the near future and 600mm blades will be a thing of the past. Second, I wanted to keep all of the servos in a removable module for ease of maintenance and wiring. Notice in the pictures there are no wires traveling against the frame, they are all contained up front in a nice clean manner.
- CG - the prototype CG is right on the button! Both horizontally and vertically. My goal was to keep the vertical CG as close to the N9 as possible as this will affect how the machine rolls. The N5 rolls as good if not better than the N9.
- tail belt? - As I designed this helicopter I was also 50/50 on the tail belt drive system. After flying the N5 with a belt, I am very happy with it's performance. Sure you give up a little in auto rotations but the piece of mind you gain knowing that you can reverse piro flip the machine, drag the tail in the grass, and be as aggressive as you want with the tail, is priceless to me.
- flying characteristics - The N5 flys like a very light N9. You still have the solid tracking and forward flight speed the N9 is so well known for yet you are able to toss it around much more aggressively without loading the motor.
- final spec? - Yes, what you see in the pictures is exactly what will come in the kits.... minus the canopy of course as its still in development. The only difference is that the parts in the picture are not anodized yet.
- control system - The single shaft CCPM control system in my opinion is top notch. First flight on the N5 I picked it up into a hover and it sat there like it was planted on a shelf, no trimming, nothing! One of my dislikes about the N9 was the super long elevator rod. It works but it had to go in my book.
- spares - I'm not in control of the pricing but I will do my best to try and keep it affordable.
- Canopy - Yes, the canopy is still in development. The canopy on the CAD drawing is just eye candy right now.
I will try to visit this forum as much as I can to answer questions but I can't promise anything. I'm trying to reach my goal of 200 flights in order to ensure the N5 is solid for the public.
Sincerely,
Matt
