Indoor stunt demo models

[Larry Renger]

OK my Gymnast was barely adequate, but probably not ideal for it’s purpose. On 15 ft lines it hit the ceiling and was soft on overheads.

We need a design that will look good and fly anywhere in the indoor sphere on short lines. The competition slow stuff is not what is needed. It needs to look exciting, and fake combat capable.

The point is to generate excitement in the crowd, showing off what CL can be.

Surely I am not the only designer capable of looking at this problem! Brett, Ted, Bob, Igor, this is worth attention!

There are two basic problems, the proper power system that actually can be purchased and the airframe to use it. In some respects, this is a whole new regime with no precidents for guidelines. A real challenge for anyone who will take it up.

No, I don’t want suggestions, or “Well, I haven’ t done this, but” comments. Let’s see some real working concepts!

I think the power system is the place to start.  Probably a 200 2s battery and aiming for 1 minute flights is a starting point. Motor and prop matched to that. Once we have that system, model design to optimize use would come.

For example, a scaled down Mackey Redwing with extreme outthrust might work. There have been other designs that maximize line tension.

The field is fresh and open. Are you guys up to the challenge?

How about a micro electric Bi-Slob?

The Gymnast is pretty good, but there have to be better designs out there.

With 15' lines, a motor would be an after thought.  "Whip Power" would provide most of the energy needed, except for overhead stunts.

Do not subject non-modeling observers to the sad antics of a Bi-Slob.  It would give the public the wrong impression of C/L stunt.  Any potential model builder watching would be turned off and would explore some other form of hobby.

Hello I think a rubber model (scale preferably) converted to control line with a good aerofoil would provide a nice looking model to please the onlookers that would not look like all the indoor 3D R/C stuff.
Yes I have done indoor C/L before but using a 'large' 36" Aeromodeller Mirabilis but on 35 ft lines but in an indoor stadium . Also flown in our lounge with a small RTP model scrapping the ceiling on full power. 
Indoor control line is booked for the 11th of March with the Whangarei club here in New Zealand hopefully I will get some pictures to post of models flown

CL stunt isn’t necessarily the goal. Fun is! And the “antics” of a BiSlob are fun, not sad.

I have not gotten and indoor CL model going yet.  But showing people the fun of CL should be the goal.   I've known people that taking off,  fly level, a few loops(both ways),  inverted and landing is a big thrill for them.   First time I seen carrier and scale with throttle control I knew I had to do it.    The late George Leib told me he had more kids flying throttle control CL because they could land when they got dizzy.

[Larry Renger]

That’s why our ET-1trainers use radio throttle control by an outside observer. 7 laps seems to be right most of the time, or if the student is really screwing up (some WANT to crash) we can shut it down. We also can cut the power in crash situations.

When the motor starts, a kids hearing turns off in my experience.

By the way, plans are available in the thread in the 1/2a section. Enjoy!
