Lithium Ceramic Battery.

I wonder when these will come out for helis, I would love to throw away all my lipos and replace them with Lithium Ceramic as long as they can perform just as good and if not better than Lipos.

 

No, the servos survived the first bad crash because there was no direct force applied to the servo arms. The second bad crash was a result of bad control input on my part, the resulting crash was at an angle that torqued the blades downward resulting in transference into the links and servos. There was enough force that the servo links were bent. That's too much torque even for a metal geared servos. Broke a tooth in the elevator servo and now the left ailieron servo has the jitters.
New servos shipped today, should get them in a day or two..... warehouse is 5 hours away.

 

Wow. I finally got to watch that! I wonder what the mAh and C rating is on one of those? If they can get power to weight ratio the same or lighter than that of LiPo, that would be great!

 

I discovered a nice little feature of my Align 45A ESC....
The BEC voltage is variable between 5 and 6 volts instead of "stepped settings". I was able to set output at 5.2v to offset voltage drop under servo load so that BEC output doesn't drop much below 5v.... a little safety margin there without pushing full 6v on the servos. I think that should work well.

 

Yeah I hope they can pull it off. No more fire risk.

 

I see the Lithium-Sulfur batteries are on the brink of being perfected. They look promising, but I'm not sure about the safety issue. It seems inherently dangerous in general to have so much potential energy contained in a small package, no matter what chemistry is used... hopefully they will prove me wrong.

 

I welcome what ever new battery technology that arrives on the heli scene, as long as it addresses the fire safety issues that our current lipos have. I've seen to many rc helis go on fire by a crash(this has to stop).

This definitely needs to change. I'm surprised they haven't made one yet after so many years. Lipos has been on the scene for quite sometime.

If we can use our current setups(willing to change if it's really good) and no performance sacrifice, I'd be all for it. I'm sure it would be pricey at the start, like most things new, but once it settles in the market it would be more affordable.

 

I'd be happy to see increased capacity per given standard size pack. Can you imagine getting 20 to 30 minute flights out of a pack the size of a standard 2200mAh 3s Lipo?? That would be awesome! I'm getting 9 minutes out of a 3000mAh 3s as it is.

 

I like the fact that it has copious amounts of potential energy. Ahh the power! Two things can happen, either our battery weight reduces and the heli becomes a super super smak machine, or we have incredibly long flight times smaking about for 10 minutes! Wow you brain would be fried!

 

Oh let the fun begin.....
Tracking says my servos have arrived at home. I get to split the SE frame and change servos this evening.
I'm curious to see how the new store-bought batch compares to the ones from EBay.

 

I know.... I get what I pay for... so don't say it.
I had the rear covers off the new servos to shorten the wires and noticed one has a different control board than the others, but same as the old ones. I will definitely be going for better quality servos on the next batch. Anyway........
Fresh servos in place. Wiring routed better than last time...... Time to run setup and get things properly calibrated.
Will fly tomorrow.

 

I feel you. I just received my main blades today that I got from Ebay. Carbon Main Blades, not sure if they are, they flex quite a bit and measures upto 310mm from bolt to tip. For a budget 450 heli hope it can handle it, being a tad too short. I was expecting 325mm from bolt to tip. Just need to find the time to balance them

 

Most 325mm blades seem to average 315mm from bolt hole to tip, so yours should be fine. Even if they were a tad short, you could make up for it with more head speed if necessary. Why they measure them root to tip is beyond me.
EBay is a good place to find cheap parts, but check the ratings and feedback comments of the seller, especially from overseas. I know from experience.

 

Hey Beaver, the servos i used to use were expensive but really really strong and fast. They were MksDs 95s . You should be able to pick some up second hand i would think. A titanium gear set is 15Au... but like i said they rarely strip on a 450.

But now i use BK servos because they have more torque for my 380. BKs arnt as strong but they are fast and can really push through some tough situations.

 

Yeah I was aiming at 3000HS, I really don't want to go any higher as I'm not sure what the max HS rating is for these blades. I'll see how they go on 3000 if they go well I'll keep them if not I'll either bump it to 3250HS like yours or I may try something else.

 

3250... Is that with 150t main and 13t pinion?

 

Okay.. This stupid iCard has got to go! I had to bind the Tx/Rx, and it screwed my channel assignments again. It has no Rx setup functions, and I didn't have my laptop with me. I had to run in a "fixed pitch" setup just to get a test hover. I'll be ordering a Bluetooth adapter first chance I get so I can use the Vbar app I already have on a smartphone.
At least I know the servos are stable and working well again.

 

I've got a couple of pinions on the way not sure if I'll be going the the 3250HS yet. Hopefully not.

 

What motor are you going to use? (What Kv?)

 

similar to yours shiny silver motor around 3600Kv
