Forward thrust
 

Planning to build a airwolf fuse with a custom retract. Can anybody tell me how can I get a forward thrust so I can drive the heli around while in ground?

In the full size world the cyclic is pushed forward to tilt the rotor disk forward and just enough collective is brought in to taxii. The rotor of models generally isn't free to teeter because of the rubber bushings which try to hold it square to the drive shaft. But even so, you can get some amount of disk tilt. I'm pessimistic about getting enough tilt on a model. Softer bushings will allow more tilt. If you can't get it to taxii as is you might try the softest rubber you can get. The flight response may be less than desired but it might taxii on a smooth flat surface. But because of the limited tilt angle I'm thinking the model will be on the hairy edge of lifting off if it taxis at all, so be very alert cuz it may come off the ground with a full load of forward cyclic and that could be exciting.

I think everything will be on an individual basis here, try it out and see what you can come up with. Maybe rig up some training gear to prevent a tipover while you test this out. It definitely can be done though, there is a video on youtube of some heli with an airwolf kit that performs rolling takeoffs/landings and seems to taxi without much problem at all.

Enough power to get it to move foward will bring the back wheels up off the ground. Believe me I tried it just doesn't work well.

Thanks for the tip guys. :):D

The Airwolf from the TV show had jet enjines on the side for forward thrust. I assume you want to replecate that? Depending on the size of the helo you could use EDF, electric ducted fans....

Now THAT would be cool!

I wonder if you could put a duct on a turbine heli to shift some of that power to thrust?

Maybe you could set up some bottle rockets to push it?

RE: Forward thrust
 

Model turbine helies generally have the turbine laying down, so that it wants to push the heli forward by nature. To counter this, the exhaust is normally ducted in another direction (for example, split into two, one directly right, one directly opposite to the left). Shouldn't be hard to remove said ducts...

well nice... now we just hav to save up for a turbine..
