Radio Shack Extreme Rescue... - Page 2

Woah... its like I am letting a baby meander near the highway!

I dont care about this toy, that right toy! just like very other RC helicopter, enough to even invest further in fixing it.

All it did was hover for to seconds, swirl around and crash. Useless! Im going to get a few clones for cheaper that will work better.

But thank you all very much for the suggestions you have made to me about keeping the weight down and whatnot, I appreciate them although I am giving up on this little toy.

That about says it all. Even a child learns that he's gotta take care of his toys if he wants 'em to work right... if the child has any brains, that is.

So you're telling me there are brainless children out there? oh no, zombies!

RunsWithScissors · Aug 27, 2006, 06:14 PM

I dont care as in I have given up on it and moved to bigger (not physically) and better toys. Like the micron and the picco z.

I feel sorry for the girls, when you get around to chasing them.

Aloha,

Of course the nickname you chose to use, says a lot about where your brain is.

ok scissors we get it, you're leaving you don't like the br xtreme rescue. Done deal. Have fun.

how do I fix the gyration problem with the rotors? The upper rotor is fine, the lower one only allows for a 30 second flight. How do I fix this? I'll take the canopy off as suggested first.

left you a message in rtf forum...glad you found your way here. the stickies at the top of this forum will answer a lot of questions. also dont know which bladerunner you have...there is more than one. i have the rescue..the mini..its okay but cant do to much with it....going to get the piccoz tommorow if i can. jeff

As far as your question is concerned, be aware of the fact that it is so vague, we have no idea what you mean. You MUST be more specific about what is going on with your bird. We're not mind readers, you know, no matter how much we know about the BR.

Although all the BRs are pretty much the same, there are minor differences that make a difference in how we are able to help you.
Get back to with as many details as you can so we know just what it is you need to know.

Aloha,
Steve

Please disregard the last 2 lines of my last post. The personal confuser is getting more and more confusing

I have the exteme rescue one. What's happening, is the lower rotor blade has a large amount of wobble, which gets the helicopter gyrating and the amplitude of gyration continues until the rotor blades hit one another and it falls down. I've tried adding weight to the nose to get forward flight, and it doesn't work. It just gyrates more. I pulled off the canopy, it got quieter, it was lighter on it's feet and flewa bit better, but the gyration is getting worse and worse. I can get video, but I cannot compress the video enough to post online. I'm browsing sourceforge.net for a freeware compressor. It'll be a few.

micro_builder · Sep 02, 2006, 02:40 AM

sounds like the rotor is out of balance, or one (or more) of the blades is "out of pitch." i.e. one of the blades has more or less pitch than the other blades on the rotor. its can be a pain getting the pitch of all the blades as close to the same as possible, but its certainly worth it.

Accu157

What you describe is most likely the hinges of the lower rotor having too much friction. The rotors must be absolutely free to tilt in any direction. Normal reasons for not being free enough are:
* Friction in the hinges (glue, bad alignment of the steel pins etc.)
* The rotor blades not being equally spaced around the circle creating internal bending forces between the rotor blades that prevent "free tilting"
* The rotor blades being too stiff (could happen during molding)

Please check that the hinges in the rotor centre are OK and possibly put a drop of plastic safe oil on them. Make sure that the blades are equally spaced (it is possible but difficult to correct this).

Normally these problems can be fixed by adding small weights to the tip of the lower rotor blades. I normally use 2 pieces, 30-50 mm long 1mm soldering wire and spin it on the ring (like a coil) positioned just behind two opposite pointing rotor blades. A small drop of glue will hold the wire coils fixed on the ring while the rotor spins.

Hope this works.
Petter

They definately have more friction than the upper rotor. BUT, the lower rotor swings more than the upper rotor when I have the blades spining, and I rotate the helicopter. I figure the response rate of the upper and lower rotor should be the same.

will do! And I'll try adding weight last. I have some standard metal wire I can use to wrap around the ring. Let's see, I checked the rotor hinge and it's been straightened out (was crooked), didn't help. I flexed the rotor blades so they're all at the same height. And, I balanced the lower rotor blade with tape and a magnetic balancer. Sometimes, I'll get lucky at a hand launch, and get a 30 second flight before it starts gyrating, so I'm getting there. I hope every little adjustment helps!

FWIW, I noticed that mine gets into the same situation where the lower blade oscillation starts and then gets worse until the whole rig becomes too unstable to remain airborne. This seems to happen most to me under fresh battery conditions...once i've used up some juice the whole rig becomes very stable.
