Kyosho Caliber 120 Review My Findings Part 1
 
The first Caliber 120 I got, did have a defect right out of the box. Forward/Reverse servo kept jamming, which made flight impossible. Tinyrc.com really went above and beyond in helping me get a replacement.

I'll start with my experiences on Caliber 120 #2.

I bought a second battery, which obviously give you more time to fly, and with all the testing and tuning is a must in my opinion. You can charge a battery while your flying, which, again keeps you going. 4 AA goes into the Transmitter, and gives you 4 full battery charges. Totally dead battery charges in 40 min. You get 10 min. of flight time.

This is NOT a flies perfectly right out of the box. I've put about 4 hours of "flight" time(if you want to call it that) in, and it still is not flying right. Follow the instruction, seriously. Put the training bars on, check all the settings, test controls. Look at all the videos on this site, I found at least one to be very helpful. Give yourself as much room as possible. Maybe in time you can fly it in a smaller room, but not at first.

My heli keeps flying in semi wide circles to the left. I know what you're going to say, adjust the trim, check this, check that. Believe me, it's apparently not that simple. I've checked and double checked, I've fooled around with the trim a 1000 different ways. And when you change one aspect of the heli trim, it almost always effects another.

After 9 flights, nothing has broke, which speaks for it's durability. It has great potental, but patience is a must, and more feedback is needed to help with these issues. It's still very new, and I hope in the near future we'll get the experience and feedback to help those who need it.

Any other findings, I'll post as I get them.

Thank's for your review on this Crow. I've been interested in this helicopter for a long time after flying my Eflite MCX alot. My Dad is currently at the AMA convention show in California and he reports that they are soon to come out with a much more improved version of this helicopter which I beleive he said has collective pitch.

Thanks C! :) Yep, this heli can take quite a bit of setup, the dual-pack tip is a good one as you're going to spend several just tweaking the settings etc. Keep us abreast of your progress and share any new tips you discover etc.! :)

C, got your Caliber 120 running nicely now? :)

I contacted Kyosho about my issues, and ended up sending it to a Kyosho Helicopter technican. He was very helpful and he basicly confirmed there was nothing wrong with the Heli. He did however tweak a thing or two, like balance the blades and it flew much more stable.

Still I'm not happy with the Heli at all, it still is extremely difficult to fly, you really can't do anything with it but go up, hover a little and come back down. Any input, even so slight really makes it a extreme challange to keep under control, to the point that it's really not enjoyable.

If anyone would be interested in it, I'd give it to you for half what it all cost me. Just really unfortunate it's been such a bad and stressful experience. I have a hard time beliving that it's just me, and an experienced R/C Helicopter person would have a better time with it, but I can't say for sure.

HI there. My Dad just shipped a big package from California. The package contained the helicopters he purchased from the AMA model convention in southern California. He's still in Auburn with my brother trying to fix his 1:1 scale airplane.
Anyway, some thing's to report. He told me that the Kyosho helicopter is absolute junk and not of Kyosho-typical quality. It does not fly worth beans. I tried to fly it, and it just spun around and flipped over.
Here's a picture of the Kyosho micro helicopter next to my MR15.

He also bought back the Walkera 4-3Q Hughe Cobra. I have to say that this thing is freaking awesome looking! Fly's better than the Kyosho, Dad claims it's way, way better than the Kyosho, but I can't fly it at all, prob's my skill level. As I just simply love this little helicopter's style, I'd love to learn how to fly it.

Then there is this bigger one, the Walkera 4-Q3 3D Mini Helicopter which I think is the same one Hammer first got. I know nothing of this helicpter and I've yet to try it.

Then he also bought back this cute little Airwolf fuselage for a Hirobo helicopter. Was hoping it was for the Quark, but it's for one of his co-axials.

Any tips on making the Kyosho fly like it should?

Urm, Marc, how many helis do you have!? :eek: :D RE the Kyosho - check out the vids, it can take a lot of tweaking to get it stable:

C, any chance you could get details on what precisely he did, I bet it would help a lot of people out who are having trouble w/ setup? :)

MAKE your 120 SMOOTH
 
I am an inexperienced RC operator, so, after breaking the balance bar on the (uncontrollable) 120 i had to use a quick fix. I deliberately broke off the other balance bar "blade" and fixed two fishing "shot" weights on the end of the bar (easy, just crimp on). I needed to experiment with different weight shot until it flew the way i wanted and the weights did not absorb too much power. Now its almost hands off!

When I get a replacement balance bar I will insert two smaller weights in the bar blades instead.

This should transform the characteristics. Experiment first with blue tack. If you are more experienced than me (not difficult) then you will need lighter weights.

John.
