e-Hirobo SRB Quark - Lepton - XRB Coaxial > XRB Lama & Carbon Blades

I just received a set of carbon blades for my XRB lama from the good folks at Star Flight (great service - thanks Alex) and wasnt overly impressed with the performance of the lama after installing them - I had the setup dialed in with the stock foam blades just fine - i could hover hands-off and the stability was great - but with the CF blades I cant seem to come close to the performance (ie. overall stability & handling) I was getting with the foam blades.

Does anyone that has an XRB with CF blades have any set-up tips or experiences they can share? Im new to the hobby (the lama is my introduction to the hobby & now im hopelessly hooked like the rest ...)

Thanks!

this is my first and only heli as well, and I too just got a pair of starflights carbon blades. I agree that the heli is not as hands off stabble as with the foam blades, but from what I understand the xrb is exceptional in its stability. most micro heli's require constant control imputs (from what I have read). So I think the change in stability actually brings it closer to responding like other micro's.
make sure the tracking is perfect that helpped a lot.
otherwise enjoy the quick manuverability and lack of blade strikes. these come at the expense of stability.

There is zero point to carbons on the XRB...

The foamies work as well as they need to and if you crash they wont trash the rest of the heli...

Carbons are completely pointless with the price of foamies as well...

I have a XRB with the same carbon blades. What I do is use only the bottom carbon blades and the top ones I use the foam. It makes the helicopter fly a little more stable. It's not all over the place with the combo blades. It's also not as twitchy with the combo.

Take Care,
Cheers, Patrick

Thanks to Chernaya & Patrick for the insights..
Using the carbon B blades and the stock foam A blades works well & brought back alot of the performance I was used to having.

Dokey/Galifrey: My main reason for trying the carbon blades is to reduce unwanted blade strikes that happen once in a while when I have to make a few...how should I say.... last minute direction changes to keep the lama from crashing into my wall (or my cat)!

Im riding that newbie learning curve and loving every minute of it!

The carbon blades, being more rigid, are probably reducing your coning angle, which is why the heli is not as stable.By using carbon
blades on the lower set only this would increase the distance between
the upper and lower sets at the tips, thus reducing the chances of the blades hitting each other but also increasing the chances of killing the cat.Personally I think that if you are managing to get the blades to collide on a regular basis, you need more practice not carbon blades.
The foam blades are the sacrificial part to save damage to the rest of the machine, so you will evantually break something more expensive.
How much did you pay for the carbon blades anyway?

Nivlek: You are absolutely right..I'll be the first to admit that I need more stick time..ive only had the lama for a bit over 3 weeks. Everything in this hobby is brand new to me, so evaluating what the CF blades do to the performance of the chopper was to satisfy my curious, tweaking nature. I figured for the $50 i spent it was worth checking them out..worst case scenario if I dont like them i'll get rid of them.

I ordered the CF blades after mashing through a set of the foamies recovering from some early nose-in trials.... It figures that since ordering the CF blades I havent broken any more foam blades. Ive got a much better feel for setting up the tracking & pitch angle, so im starting to get some feel for how it "should" perform.

Thanks to runryder..great site!

If you're trying nose in after three weeks , you're doing pretty well.Just
make sure that you don't hit yourself with the carbon blades!

Thanks for the props Nivlek!
I'll keep my face a safe distance from those CF's.

The lama is so stable in-flight that I was tail-in hovering almost right out of the box (ok, I mashed a set of foamies into my entertainment center on my first attempt at lift-off before I was hovering). My flying space is limited, 10X10x10 at the most, so Ive had to sharpen my skills quickly to avoid depleating my supply of spare blades!

The XRB is a blast - great fun. Can't say if it's a good training platform, but practicing pinpoint landings on the top of the TV is a great way to burn up a few hours!

I think it's a good learning tool.I've been flying heli's since 1989 but I've
got an XRB for some indoor winter fun!One of the guys at work has also
got an XRB to learn on, so we have a quick fly at lunch time!Once you've mastered the XRB you shouldn't have too much trouble transfering the skill to a bigger heli.

The llama will already hover itself with foam blades...

CF's just add cost, danger and damage in a crash....

>CF's just add cost, danger and damage in a crash..

I can attest to that. I, like most bought CF blades to reduce the consumtion of foam blades. And they did survive a rather spectacular crash without a scratch. However the force of the crash was transmitted to the rotor head assembly, which was totally torn up!

The good news is that it was cheap and easy to rebuild the broken assembly, and I am back on foam blades for now. But I must say the XRB sounded much cooler with the CF blades. Sort of a real turbine kind of sound.

Imagine what would happen if the heli hit you with the CF blades as well...

Carbon fibre tips at 60mph arent very forgiving...
