I really like my carbons on my mini shuttle and it flies great, but would the carbons be harder on the motors? Has anyone else had motor failures with these xrbs? Iv never ran mine over 7min because heat seemed like would kill them.

Yup! I prefer the carbon blades to the styrofoam ones hands down. The heli responds better. You might have to get a little use to it, but they are sturdier too. Last night, I the heli blades hit the my wife's display cabinet and the coffee table legs in the living room (I normally fly the heli in my office building's enclosed basement parking area.) I don't see any visible damage on the heli shaft but chipped off some of the plastic lamination on the blades. But the heli still flies fine.

I just got my xrb mini shuttle back from mrc. I have had this heli for six months and started loosing power after seven min flight time. Tim at mrc said I had one bad motor and that he replaced both motors and gave me a spare lipo. Thanks Tim for the great service. Mike Ford.

XRB Bodies
I read in one of the forums that replacement bodies are available for most XRB sized electric helis. Does anyone out there know how I can get one. I just bought a Lama from a fellow out in Wisconsin. Now I have a Lama and the Shuttle.

The Lama should get to me within the next 20 days. I want to modify the Lama. I also saw a full carbon fiber mod in one of the heli websites. The fellow was flying it outdoors. I wish I could do that.

If you laminate the styrofoam blades with tape, they are incredibly resiliant and they don't nick up furniture, pets, people, etc.

I would agree with Rick the tape laminated blades are much better than stock. Just take your time when doing this to avoid any air bubbles and ensure that the will come out balanced.

Also think that the carbon blades make the bird much more responsive. So it boils down to this if you want a quicker XRB then go carbon, For slightly more robust blades tape em.

Now if you have to many helis and a kid who goes thru huggies like there is no tomorrow then you need to consider selling one of your favorite toys. What is a full up carbon XRB worth these days? meaning carbon swashplate, frame, and yes blades.

They fly great.

The skelaton thing was actually a winged creature from Walmart. The rags are very articulate in that the stuff moves drasticaly in the rotor wash. Use that with a little slip and slide with the yaw control and you have kids loving every minute. Smiley lands on the belly and the arms keep the rig stable. When you lift off, the arms lower which gives the impression that it's grabbing at you. This rig is a few grams heavier than with the Lama pieces but flight time seems the same. Flight controls feel the same as well. Plenty enough to horse the XRB around a bit!

The skull is lighter than the Lama stuff that is removed so it actually gets increased flight time and the power to weight ratio gets a bit better. It's just not as much fun as Smiley is for the rugrats. It's lighter weight calls for a little less gyro as it will oscilate sometimes. It's very light and you'll notice the difference from stock config.

BTW- I tried Smiley with my stripped down Blade CX and it barely got into ground effect. It couldn't lift the hands off the ground. That made for an interesting slide event over lenolium flooring. It appears that the XRB has more lifting power than the CX. It has more punch, I think due to lighter blades and coreless motors.

Spencers Gifts has a much larger version of Smiley that I want to strap under my Graphite 60. That could be made up for night flying. Imagine the light kit for something like that. Do up a couple of them and chase a T-Maxx with a glowing varmit shell of some sort. That would be funny.

Not too many people flying XRBs anymore I guess...
Heh...

Seems more than we thought are still flying these! Now that cold weather is setting in I've been flying this indoors in the gym at a local rec center. I'm loving the little guy.

Somebody mentioned batteries....

I cut the end off the original battery (No, I am NOT paying $50 for a 2S lipo!!) and made an adapter so the thing takes regular JST connectors. Been using VampowerPro 850 mA 2S packs from my LHS at about $21 each new. They fit the battery tray perfectly.

Anyhoo... glad to see some folks still flying and yapping about their XRBs!

Anybody got a BT frame for the XRB for sale??

And for those who get really bored, try this with a set of goggles. FPV style. I can hover and cruise room to room if I use my diversity receiver and place the two antenna in seperate parts of the house.

XRB
Been flying XRB 3 seasons( winters) and it jsut isn't quite as stable as before. Not suprising due the 'use and abuse' over the last few years. Any user replacement parts that I need to look at that tend to wear with heavy use?

Hey Rightflyer,

I'd replace the blades to start. Have you noticed the coning angle increase? Undamaged foam blades will get weak over time, particularly at the root of the lower (controlling)set. Also, look at the gears and pinions. They wear slowly but are easy enough to replace.

What ever you do for abuse, don't hover it with only one blade top and lower. It will do this but the high freq shake WILL kill the gyro pretty quick. Sucks to be stuck doing piroettes full time....but good practice.
Hope this helps...

I got my new XRB Bell 222 last Monday. The body and paint job is awesome. The electronics and motor are encased in durable styro. All trim adjustments are located at the bottom of the heli. However, unlike the Lama or the Shuttle, the 222 does not have a cover to protect the trim adjustments from dust and grime. To access the the swash plate, pitch adjustment screws, and the upper gear, you have to remove the exhaust cover (which I thought was pretty nifty with the wire mesh to simulate the heat exhaust) which attaches to the main body by blunt pin-like pegs and a guide. Unlike the big brother Hirobo Bell 222 (for the 60?), skids are used instead of the tricycle wheels setup of the real McCoy. Hirobo scrimped on the battery holder, too. It felt too brittle unlike the thicker plastics used on the Lama or Shuttle.

Out of the box - it was more stable than the Lama or the Shuttle. (Considering both the Lama and Shuttle were very good out of the box.) I flew the 222 around the living room....it was great fun! Disappointingly, unlike the Lama or the Shuttle's more than 15 minutes of flying time on one battery charge, battery life was a little more than 10 minutes. This is probably because the heli is heavier than the 2 previous Hirobo XRB models.

Given that it is heavier than either the Lama or Shuttle, I wonder if I can fly this outdoors...hmmmm.

I plan to install tricycle "landing gears" using resin attached to the undercarriage. They will be falsies since I will be retaining the original landing skids. I will also look into using parts from the new Esky Dauphin fix pitched helis. I also bought the racing mechanics set (1:24) made by Tamiya and will modify these to look like chopper pilots. I'll take some pictures and post them on this thread when I am done.

Just got to fly the XRB again last week. Its still a blast to fly inside. Thumbs otherwise atrophied due to winter. Spring is coming soon. Gotta try that new TREX 500!

Does anyone still sell the carbon swash for the XRB? I need a few for myself and friends. I think it was Ricks that sold them but I can't find them. Thanx...The beatings will continue until morale improves...
