Designing an indoor micro model for a 4m by 4m (12ft by 12ft) area


Obviously my flying space is limited. I have ended up tethering my twin motor RC "J3 Cub" to a line and flying it outside. There is simply no space to turn, and maneuverability is limited because of the differential engine thrust type of control.

Time to start from scratch again. What I need to build is something like a 3 channel paper plane (throttle, elevators and ailerons) that I could fly indoors and outdoors on a calm day.

The radio will be standard 2.4GHz unit. I have quadcopter transmitter but not sure if I can use this - seems proprietary.

The receiver will have to be lightweight, and so will the servos and battery. I am willing to compromise on flight time of about 5 minutes with spare battery packs to start again once one pack is used up.

Preliminary testing will be done with glider and free flight models suitable weighted to see if they can turn in a small space. High AoA flight is a distinct possibility.

See this thread: Post # 10 has a Mirage that seems to be suitable for this purpose. Also see Post # 19

IF you want to make one ... for PERSONAL use only (i.e., NOT for commercial sales use: world-leading major toy company Spin Master has excellent legal dept.)

That's really amazing. It just demonstrates that there is a need for this sort of thing. There is also a twin rotor helicopter like concept that seems interesting,

Will watch the videos and get back to you. I cannot understand how it would work...

It flys in high alpha mode to induce slow flight , but the plane looks like it was designed to not look like it is flying nose high.

It uses a single throttle stick for controlling the power to the motor.

At the lowest setting, it goes straight and level, or was suppose to.

More throttle makes it start to turn.

Full throttle makes it turn sharp ,and start to climb.

These are similar to setups that were used in free flight aircraft. You would set them up to circle one direction under power, and the other direction when the power ran down. Keep them in the field that way.

I think I would have a lot of fun with this idea of an indoor or calm conditions outdoor plane that turns one way power off and straight with moderate power then circling the other way with high power.
A few weeks ago I spent $11 on a Vroom Zoom and used the components to make such a plane. It was coming along nicely when the gears stripped and I shelved the project for the time being.
I was hoping to have a very light and slow plane. I'd like to try again and am wondering if the components used in the room raider are of any higher quality than the stuff in the vroom zoom, which I found to be quite disappointing.
I've always enjoyed the philosophy of doing more with less. Sailboats and gliders forever!

To get the store-bought one to do this with a simple UNmod taking only a few minutes, see >> https://www.rcgroups.com/forums/show...ht=Room+Raider

The original Vapor from Horizon, was and still is the best limited space flyer I have seen
All up is 14 grams flies 5 min easily
Flight speed is walking speed once you learn to fly at slightly high aoa.

Anyone use Night Vapor components to build lets say a model for slightly different aesthetic tastes? For example a transparent wing Cessna 180 or the like?

The trick, is to stay at 14 grams
a change of 5 grams is extremely noticable

For the overall design, I think the following site is a good start. (Results from a web search).

http://micromodeldrome.com/quick-bui...inted-68-c.asp

For RC equipment: (from the website)

"using the all in one Rc equipment such as AR6400 or other all in one "Brick" type of equipment"

The control system could be built around this?

Or is there any other Tx Rx combination that is low cost and suitable for micro indoor planes?

8 grammes flight weight, this is the one to beat. Maybe some high lift devices will help. Pretty impressive.
