I just purchased the XRB. Amazing Heli. Anyone can learn this one. It has the dual main rotor blades to counter the torque. It flys better than the small electrics I.E. Dragon fly (Junk) I know because I bought one on Ebay. It was a $99 special. I opened the box, charged the battery, turned it on and watched it embarrass itself while it kept tipping over. The servos were not working properly. They were sticking, so every time you used cyclic, it would not respond. It would just tip over and break. In the trash it went. Not enough money spent to get a head ache out of it. Junk it, Much easier. So the XRB was purchased, Right out of the box it flew like the pros. In and out of tight spaces Nose in, Nose out, left turns, right turns what ever you wanted. The only issue was the vortex that it created near the floor. Flys best above knee height. If anyone has one or wants one, they are great for indoors with the coffee cup foam blades. They break easy so you don't break the wifes vases. And it won't hurt the cat either

Here for a good time, not a long time!

XRB lama

Thanks for responding on the XRB Lama

I bought mine with the intentions of letting my employees learn to fly. Then, maybe I could get more involved with the hobby. Once you try it, your stuck in this hobby for a l-o-n-g time. The heli is so much fun and very easy to learn. The stick movements are the same as the big helis, so that will keep you in shape during bad weather. It's meant to be indoors only! I have repaired the XRB several times, because the guys are flying too close to the office furniture. No problem! The blades are so cheap and quick to replace, that they can fly whenever they want, at a minimal cost to me. ($10.00) a box of blades. Thats alot of mistakes. I also purchased the optional cockpit through MRC international. Makes the XRB look much more realistic. Have fun with yours, and share the excitement with others!!!!

I absoulutely love mine! By far the most fun you can have indoors (with your clothes on

). Wife gets a little nervous when I'm doing funnels while shes watching TV, but she is getting used to it. Also great to chase the dog around. Would be great to learn on too because it is sooooo stable! I highly recommend it.

My only complaint is that I wish they would offer it without the TX for a lower price, because I fly it with my 9C anyway.

Thought about buying one of the cheaper colnes, but was told that they are not in the same ballpark.

I learned the same thing today. If its not Hirobo XRB, I won't buy it!! There is one out there now that I heard was being sued by Hirobo. Called the HOUSEFLY. Stay away from it

I'm trying to find the thread but there is a full story about this young guy who'd had the whole job made up , then was ripped-off , left on the learch.

I think it's on rc-universe !!? Any one Know who's the first twin motor coaxial rotor xrb inventer ? But it's good to clamp down on theSIZE=large]fads ![/SIZE]

Pantent? What patent?

That's what they will say in court. The hard plastic main blades are no good for this heli(Housefly). It causes alot of harmonic vibrations, the foam blades are the best, because they offer forgivness. More flexible, not so rigid for such a light heli. It's not needed. This XRB is perfect, except the main construction could be alittle more durable. A small unexpected crash could cost you a bank-breaking $12.00 to fix

I wish my Fury Extreme was that cheap

I haven't yet, but I will cross my fingers every day

Damage repair costs

I too enjoy flying the Lama but I don't think the repair costs are all that reasonable. If I hadn't gotten creative with carbon fiber, glass cloth yarn and CA glue, I'd be on my 3rd set of landing skids and tail boom. At $10 a pop for each of those and a couple bags of foam blades for good measure, we're talking at least $60 in parts for about a week's flying.

It appears that someone with a military defense contractor's mentality set the prices for the Lama's repair parts. For instance, $20 for an instruction manual, $98 for the XRB AC power pack $58 for the tether cable. I totaled the pieces you can buy and it came to over $380 in parts and that doesn't include a controller or servo circuit boards.

The spare rotor blades are at least reasonable as maybe are the motors (but not the SR's) and pinion gears, but I think the parts in most cases are too high by more than a factor of two. For something that is bound to take a beating because it has to fly indoors, although it is much better than any mini electric heli in a lot of respects there is still some room to be better.

Areospacer-XRB Quality

I agree with alot of it, however, you should not be spending $60 a weekend on crashes. Are you flying too close to furniture or chairs etc..
I have had mine for 3 weeks now on the worst thing that happened was the heli drifted into a cabinet about 51/2 feet up, wiped out the main blades and fell onto the boom. It cost me $12.00 to repair the boom, and one set of A/B blades. I thought that was very reasonable, considering the height of the crash. But I think they could build the heli with alittle more meat around the bones! Also, you must keep in mind that whenever you purchase outparts seperate, it is always more expensive to do that. If you buy a car brand new, completely assembled for $20,000, and bought the same car disassembled part for part, it would cost nearly $60,000 to piece it out. You are better off buying the car assembled at a fraction of the cost. And you didn't have to pay an assembly charge either! Heli's are the same way!

I've got a teathered XRB and when I break a set of blades I get out the Superglue. I've broken each blade 4 to 5 times.Each time it breaks close to the last break and reglue again.

The hassle of broken foam blades

As I said, I don't think the foam blades are a cost burden to flying the Lama, but I'm so fussy that the process of tape re-enforcing, balancing and tracking a replacement set of blades gets old in a hurry.

I have noticed that even if you don't do damage to a foam blade with a strike, they appear to have a stress life from the coning they experience. After a few flights, circumferencial wrinkles start to appear on the top surfaces of the blades due to the compression the top skin experiences from coning. I found that even the tape re-enforced blades (both sides) develope wrinkles in the upper skin. This I suspect further weakens there resistance to coning so replacing foam blades to maintain peak response is a never-ending process.

XRB Can't beat it!!

I had a crash with it. Actually it was my friends crash. The top of the main mast where it holds the flybar balance weight broke. The Balance bar snaps into the top, and one of the holes are gone now. I have ordered that part a week ago, but no luck. The mast is made solid to the tip that supports the balance bar. Otherwise I would buy the tethered mast which is shorter than the r/c one, and just switch the tops of the mast. I thought that the black plastic top was held in by a small pin, but i don't believe so, I think it's molded around the shaft. Nice heli, just alittle soft in the structural integrity. Tail boom especially!

Replacement parts

I have noticed that recently there is a shortage of replacement parts. When I first started breaking mine, HeliHobby had all the parts but now they have next to nothing. I fear that with all the Lama's out there after Xmas, there is a lot of crash damage to support.

I noticed that the grip on top of the mast that holds the flybar was sloppy on mine. It wasn't broken or cracked and so I just dipped it in a cup of boiling hot watter and squeezed it together while it cooled and it fits fine again.

Also I broke a blade grip off the feather plate in the bottom rotor head during a vicious blade strike. I think it broke because I fly with those wooden blades I made which don't break easy enough. At any rate, there is only a little trunion-like plastic knob with a metal shaft through it that the blade grip attaches to the feathering plate on and it snapped off. You can't get just a feathering plate even though it disassembles with screws. I was able to re-attach the grip with CA glue and fiberglass cloth yarn but if it had happened on the top rotor head, that repair would not work because the blade grip must be able to rotate on the trunion knob to provide individual blade pitch adjustment.

I hope the parts supply will soon catch up with all the damage the Lama XRB fleet is sustaining in the world. The Lama seems to be sweeping the model heli world by storm but they still are basically a fragile aircraft.

XRB Parts

It doesn't look good for parts, I ordered the main mast a week ago,haven't seen it yet and heard I won't for awhile. I'm not happy with that aspect. It's sleeting and freezing rain mixed with snow. I can only fly inside on the simulator. Fun, but not quite the same!!!!!
