Minimum C discharge rating for Trex

[Flyindoc]

Hello,

I have been seeing some great deals on lipos on ebay. Unfortunately the C rating is usually 10C or 12C for the low, low priced cells. What is the minimum C rating for the Trex. I am not a hard core 3D flyer, just the standard rolls, loops, inverted, funnels, etc. So do I stick with just 15C and greater or save some $$ and get the lower C rating.

thanks,

Doc

You should really aim at 15c minimum nowadays. I'm flying 3 x 10 c and 1 x 18c with no real problems, though the 10Cs can set off my lipo alarm if i come out of a flip or loop messy - so they must be dipping under voltage under hard load. Still alive and kicking though!

I'd steer away from eby deals from the far East - my friends bought a Trex deal from the East ans while the heli is great - the supposedly 18c cells that came with it are so small and light I have trouble believing they are what they claim to be.

I've had great success with www.truerc.com - ebay prices (and he sells on ebay too) from America.

I have 3 x hextronik 2200 12C/16C that are currently selling for under USD$30 from here: http://www.unitedhobbies.com/comersus6f/store/comersus_viewItem.asp?idProduct=2045

Originally I bought two and I have about 30 cycles on each of them and they are doing fine. I am a learner pilot, getting about 8 minutes of hovering and gentle sport flying to 80% discharge. The batteries are never more than mildly warm. For me, so far, they have been great. I recently bought a 3rd one. As a learner it made a lot of sense to me that I could afford 3 for barely more than the price one 1 20C battery.

My two transactions with this vendor, one through eBay and one through his website, were both OK with the goods delivered well packaged and within the promised time.

That's a nice deal for the "c" - and I agree about buying cheaper packs for learning (although, I guess, we are always learning ;-) )

Your question should be:
What is the minimum current a battery should provide continuously for a T-Rex?

As far as I know, for 3s setup, hovering is about 8-15 A, sport flying about 10-25 A, 3D - about 20 - 40 A, (all depending on the setup)

So the minimum may be 20-25 A (no 3D) and I aim my battery to provide 30 A (only hovering for now, my ESC is 35 A)

I have battery 2100 mAh x 15C = 31.5 A
I am looking for light 3000 mAh x 12C = 36 A
