705 3.5Y 4200kv
This is the motor Neu recommended to replace the razor. It is not as powerful as the razor was. That little razor ROCKED!

Who knows, maybe I got a bad one but I doubt it. I would say it has about the same amount of (perceived) power as my little mcpx, which is to say not too powerful. It used to JUMP!

I know it's working hard too because it gets plenty warm.

Thanks Terrance, I'll look into that scorpion motor. Mitch did you get the correct KV motor? Also how did you determine which one was recommended by Jose and Manuel? Not second guessing you, of all people, just curious.

The 705 3.5Y 4200 is the motor Neu recommended. I thought they of all people should know!

Looking at the entire 705 line the 3.5Y seems like the proper choice. But who knows. . . .

back in the air
Bob,

I'm finally back in the air. What a pain it was, to replace the cracked main frame and re-dialed the pitch back to perfection. Luckily for me, the bent-back shaft of my Medusa motor did not show any bad traits in tail performance.

I'm using a Futaba 401 gyro now and the tail holds up pretty well in full collective punch. However, whenever I let the rudder stick spring back to neutral deliberately, there's that annoying wag which lasts for about 0.7 second before the gyro stabilizes it. This is a step back for me, as the same self-induced wag wasn't this obvious when I was using the GWS brushed motor and the GWS ICS100e ESC.

My current trimmed settings are :

CC10 ESC for tail - programmed to fixed end-point throttle, fast throttle response and fast start-up

TX configurations
Rudder end points - 54/ 54 on rudder channel
Heading Hold/ Rate Gyro Gain - 33/ 33 on gear channel

401 calibrations -
Digital Mode - ON
Delay pot - zero
Limit pot - 15% (any lesser and the gyro would not initialize)

I started with the gain at 40, Limit pot at Full, Rudder EPA at 100/100, and I had the most violent tail wag.
I had to turn the gain down to 26 to stop the wagging, but the tail felt very loose. I set the gain to 35% to get a feel of adequate tail authority (ignoring the wag). When I turn down the Limit, it gave the most improvement, I set it to 15% and could not go any lower.
The piro speed was alarmingly fast so I reduced it to 54 where the piro-rate now is very close to that of my 500-size.
I did not touch the delay, it was all along zero.

Could you tell me what are the best settings for the 401 and a Medusa motor? I really hope to get rid of that awful wag.

Settings
Terence,

Set the delay to 100% on your 401 and the gain to where it wags the least amount you can tolerate. These motor tails are always going to wag a little.

Me, I'm sending my Neutron back to Neu for examination. It's just not right. For example: my head speed was so low that the cyclic control was inadequate. I actually ran the heli into myself and raised a big lump on my head for lack of control!

Thanks Mitch, what about the Limit, do I set it to max?

Maybe that will knock some sense into you Mitch and you'll leave these little devils alone! Terrance, Manuel Compos told me to set both 'delay' and 'limit' to 100% so I do set the delay and limit to max. Better a little wag than no wag and a loose tail. Mitch is right; there's a little wag with these things.

Head
Fortunately my head is WAY too hard for a little heli like this to hurt! Also too hard to EVER knock sense into, grin.

I took the Neutron out and will send it back to Neu for evaluation. I'll let you all know the outcome.

The settings are GOOD! During hover and collective punch-outs, they give the equivalent performance I achieved with the zero gain and zero limit configurations. But it will be a chore to turn down the limit every time since the gyro needs at least 15% of limit to initialize. Also, the full limit and full delay configurations give a cleaner piro stop, less bounce back.

So that might be 'as good as it gets' for your set-up Terrance. One of the few short comings of a blade set up like ours is that wag; a small price to pay, really. The benefits far out weigh the deficiencies in one of these little fellers correctly built and tuned. Thanks go out to Manuel and Jose Campos for their hard work and generosity!

I think it will do better if the tail shaft was never bent before. The tail blades seem to track okay at low speed, once I give it more rudder, the double-vision becomes prominent.
I have a Hyperion 4100kv on order now, I heard it is not as efficient as the Medusa, i will find out soon

I have a Hyperion in one of my blades. It's ok but not a Medusa. The best motor for the tail (even better than the Medusa) is the Neu Proton 4000. My buddy has one and it really screams. My Hyperion is pretty good but, it my memory serves me correctly, the shaft is very short. Good insurance against damage but there's not a lot of the shaft to penetrate the prop.

I run a propsaver on my proton. No pressing a prop on and hoping it stays. . . .especially in the "puller mode."

Plus it helps protect the motor in a crash.

Get a load of this
I burned a transistor on my beloved MCPX main board and had to buy a new board. My friend is an electronics buff and is going to try to fix the old board. So what does this have to do with my Bladzilla?

If he fixes it I'm going to try to morph it onto my Blade. I will have to use two brushed-to-brushless signal converters to the ESCs but everything else should be pretty straight forward. I'll be able to lose the futaba 401, receiver and flybar assembly so it will be MUCH lighter.

Can you say "Double Brushless, Flybarless Blade CP!!"

I doubt that the 5 in 1 will have the Nad's to run the Bladzilla servo loads..
But it would be a interesting project..

That's a good point. I would be willing to try it but I'm going to need three of the super-tiny servo plugs Horizon uses on their servos. Even smaller that JSTs. Anybody know where I can get some?

So...as luck would have it...I'm going to be adopting a blade cp again...lol...been a while since I've had one in my fleet...but will be a welcomed addition...I have a long history with the ol' cp...so this should be fun...keep up the good flying...enjoy the weather...





Sweaty palms are only the beginning..........

Mitch, you did some good thinking out of the box. I had something similar in mind but the 3axis candidate was the beastX. That didn't take shape because I adopted a protos mini and used the beast for it. One problem I forsee is a big drop in tail performance with a brushed 2 brushless converter. I used powerzone brushless converter and didn't have satisfactory result with a brushed motor tail, brushless tail would be more demanding.
