Rave Radio Shack Extreme Rescue...

[Sammy the Kid]

I bought one of these yesterday, just for kicks, and I gotta say I ain't disappointed. Currently she has over 25 sorties in just over 36 hours. Only thing I had to do was tape a dime to the nose to make her move forward a little quicker. Before all the heli-snobs respond with "BLASPHEMY!!!! It's a TOY!!!!", I already know that and that's why I bought it. I can realistically fly it around our living room\kitchen area without fear of making the wife punish me. And yes, I'm using it as a gateway for a larger electric heli since I already fly a number of electric fixed wings.
Has anyone modded one of these yet? Different\altered fuselage, longer running battery, unique add-ons of any kind? I've got some ideas for modeling some winglet\rocket racks and a nose cannon for doing strafing runs on my nephew's little green army men. I will post pics and performance info after I get the stuff done that I have planned.

Sammy Welcome to the wacky world of BRdom. In the archives of this forum are thousands of posts about this addictive little buggers. I think I figured something like 7000 threads last time I guesstimated. Here are a couple of important URLs for all new BR owners:

Most of the mods for the older BR will work on the newer ones, up to a certain point.

Read through the documents and archives, and you can learn how to get the best out of your BR, and learn what to reasobly expect out of it.

Have fun, & Aloha ~

here's a little info on the mini BR: http://www.rcgroups.com/forums/showthread.php?t=511767

having the 3rd channel on the bigger BRs can be nice, but i think this smaller Rescue version will last longer since the motors dont seem to be so strained. its a good 50 bucks spent, i say.

I'm on my 2nd week now with mine and I am having a blast with it. It is exactly what I wanted in a mini heli for the living room. Don't worry Sammy, I don't care what the "real" heli guys say either. Matter of fact, I bought a Lama 2 first, thinking I could use it in our living room. I guess I could, and did, but our room doesn't have a lot of open area and I found it quite a chore to keep the Lama working in there. I have been quite good at flying the Lama, never had any problems (except that one time I took it ouside and found out what a little wind can do to it ) but I never enjoyed flying it in our small rooms.
This Rescue BR has been great from the 1st flight! No worries, and it flies so darn well. So, basically, don't get in a hurry for the bigger guys, this thing is not bad at all.

I've been wary on trying out RC Helicopters, mostly due to cost. I saw this at RadioShack and couldn't resist. Being an extreme novice I was amazed at how easy it can fly, and how much of a beating it can take from crashes. Of course wanting to know all I can about this lil bugger, I found this forum and found several hints that I found very helpful. Being a modder, I had to come up with something else to add. A 2032 battery, a pair of green LED's and there ya go. http://media.putfile.com/Helicopter-mod

Before I go on and yell about this new thing, remember I own one of these, and I am not one of those "ITs A FRICKEN TOOOOYYYY GET A REAL ONE". I dont even have a 'real one' yet.

I got one of these today, I am very dissapointed.

The constant forward motion makes it want to stabalize its self. So it goes back. Then it tries to go forward because of the weight, and it rocks back and forth constatly, until it is uncontrollable. I can fly it for maybe 30 seconds, but trying to make a turn or a change in altitude will throw it off and it will swing back and forth.

What I have tried so far was putting some weights on the out side of the rotors, but that didt help too much, then taped a small carbon rod to make them stiffer which aalso helped a little bit.

[Steve Shepard]

"Just keep in mind, the BR was designed as a "toy helicopter, capable of being passively stable in hover". PERIOD! (quote from Petter Muren's original patent application) The fact that us hobbyists can manage to tweak some sort of motion out of it is just a bonus. It just wasn't designed to do anything other than hover. If you need a better explanation, read this:

Aloha, Steve

PS if you insist on gaining better stability out of your machine, you need to remove the body and fiddle with the CG, by moving the battery fore or aft a wee bit. You need to pull the body anyway, so you can "GREASE THE MACHINE! ", as my dad always said. (Search this forum for "Bladerunner Proper Lubrication). Just a simple lube job can do wonders for this delicate little bird, and it will enjoy the weight loss, too.

Well, I got reall pissed off, and just decided to tape some dimes to the end of two of the blades on the top and bottom, 4 dimes total. Its sure it heavey, but it is the most stable I have ever seen it fly.

[NoZebra]

once I openned mine up it, it helped a tiny bit. I reinforced the batter in the front and on the tail. Used gold paperclips, both functional and adds bling! They do tend to sort of wobble, mine gets a bit circular with it and I found that by sort of counter spinning helps. haven't gotten around to blackening up my rotors quite yet.

[Steve Shepard]

RWS : All you are doing by putting dimes on your rotors is shortening the lives of your motors - GREATLY! The increased moment of inertia is OK for adding stability, but you have done it the wrong way! Because of the design, what happens to one blade, has an effect on ALL the other blades, and there is actually movement in all three dimensions - fore-aft, laterally, and vertically. You have ruined the vertical component of the rotor dynamics. You would have to place a dime on all 8 blades to be able to keep forces equal. And then you would be too heavy to lift off.

Alas, the dimes also increase the load the poor, little, already overworked, motors have to get and keep in motion. The motors were custom designed for this application, and no allowance was made for increased weight. In fact most of us who know anything at all, do everything we can think of to REDUCE the weight of the bird. That is why the BR uses very flimsy construction, instead of tupperware. TO KEEP THE WEIGHT DOWN!

The motors were designed to only last about the attention span of a 10 yr. old kid - about 4-5 hours. You will be needing new motors in very short order, (then you'll REALLY be pissed off) so here is a link to get them - two links actually :

http://www.wrightbrothersrc.com/our_...laderunner.htm

http://parts.rctoys.com/rc-toys-hobb...Spare%20Parts/

And hurry up and blacken the MOTORS, not the rotors. Getting rid of heat that builds up in the motors is even MORE IMPORTANT when you have increased the load on the motors, as you have.

Shame, shame, SHAME on you! Better you read through the past posts on this forum, BEFORE you go do something to destroy your Bladerunner!

Aloha, Steve

Dimes on the rotors will wear out the motors quick...to make it more stable follow aloho steves links at top of forum...for forward flight i moved bat and added small stick on weight in the nose.I fly mine outside mostly, so did not scruff the motors and turn them black,with inside flying that will work with heat dispation. i also used the spacing on the rotors link up top it works well even on these small versions of the heli jeff

I picked one of these exreme rescue helo's on a whim last week, I have just gotten around to taking the body off and lubricating it. I was definatly suprised how much quieter it was without the body before i lubed it. I also added about 2.5cm of yellow electrical tape around the end of each blade, just for looks mainly, but it does seem a little more stable, I hope that it doesnt strain the motors too much, they don't seem to get too hot anyhow.
Anyhow, i am definately glad I browse the forums often and came across the post about indoor extreme rescue. I cant wait to make a replacement body for it.

OMG!! i just got this heli yesterday it flies great i did crash it a couple of times. It flies great right after its charged but like after 4 minutes of flying it starts to spin. What sucked is u have to by a bunch of batteries for the charger (EXPENSIVE!!), OVERALL ITS AWESOME!!!!

Im gonna send some pics later!!

I've been thinking of picking up some glow in the dark paint and doing a thin line on tips of the blades. Post pics of the body when you make it!

I find in my stuf a wall tranformer of 6V.out put and solder it (the cable) in the exit of the red and black cable what go out of the baterie holder(you need to open the charger) I have about 10 sicle(charge) in the BR and it perform perfec if you exaust the cell to the point it can't hover take 1h15m to full charch and the volt is 4.17 And you can use the batery if you whish too.
