All I can say is if this was out when I first started, I probably would have skipped 3 of the helis I bought.

I completed my second flight in the gym today.
I flew horizontal eight, about 30' to 40' width at about 10' from floor.
It is easy to maintain the altitude and easy to turn with rudder.
I set the timer in my tx 8 minutes 30 seconds and landed just in time.

One guess at why the SRB is so expensive just came to me:
Perhaps the SRB has a head-hold gyro?

I have seen head-hold gyros for the Pixie Zap/Mini-Zoom
(somewhat similar in size to the SRB)
being sold at www.helidirect.com.

I don't know whether the SRB has a head-hold gyro or not but I feel about
the same rudder stability as my T-Rex450XL or MX400pro or EP8 with
head-hold activated GY240.

I wonder why it has such a weedy battery?
Mind you it is a sub micro and maybe it can't pull the weight of anything bigger, but it'd be nice to run flight times closer to the xrb which was around 15-20 minutes. Having said that a single rotor isn't likely to match a co-ax which puts all its energy into lift.

The coreless motors in the xrb seemed to last for ages which is a good thing because they were hellishly expensive last time I looked. I wonder how long it'll last pushing that little tail rotor....I'd hate to be replacing that every 10 flights like the usual tail motors.

Thanks to cvlex for posting this outdoor flight video on the other thread:

Hey cvlex, please keep us up to date on how you're enjoying your new purchase. As posted above, I'm also concerned as to how long that tail motor is going to last. A continued "mini-review" from you will be invaluable to us that might be planning on picking one up when they're available here in the US and Canada.

Does anyone know if there is a pdf downloadable Owner's Manual out there yet? I've searched but so far I haven't been able to find one.

Heres a $50 million question. Can we separate the RX from the rest of the electronics and add a spectrum receiver, like the CX2 or lamas?

Or what about taking the Rotor head and swash and adding it to a compy 300 frame?

On the manual, Hirobo recommends to take at least 5 minutes pause or
interval between each flight, not to go next flight immediately.

I suppose that this recommendation is for cooling down the tail motor and/or ESC.
I also suppose that SRB uses 480mAh instead of 720mAh battery to let
the tail motor lasts longer.

I flew my SRB at the gym once today.
Flight time is 8 minutes 18 seconds continuous.
The voltage of the pack after flight is 7.542V (measured after a few hours
later). The rest of capacity would be around 20 to 25%.
So about 9 to 10 minutes flight will be possible if you use good pack.

Fully charged pack shows 8.372V about one hour after the charging lamp
switched from red to green (indicating charging completion).

Excellent feedback...............I want one!!
Looks like Hirobo even cut a vent in the top of the canopy to keep the electronics cool! Another well thought out attention to detail.
Even a flight timer on the Tx too!

I purchased my SRB without tx.
SRB Kits with stock Hirobo tx are not yet available in Japan.
I use my old JR tx, PCM-9X with my SRB.

The stock Hirobo tx for XRB and SRB has no built-in timer.

MRC is way too high on their Hirobo products, just compare their XRB prices as an example.................these guys below will have it cheaper, I'm sure:
