T-Rex 500 Info

[raptorheli2]

have you done the canopy post mod and tried it?

i don't think we could run a brick 6s btw as the 3s packs are still staggered to fit. a 6s would fit but obviously much lower on the tray. pair of 3200 3s packs is the way to go imo.

cheers

What pinions are you guys using with these 2 packs, also what type of flight times your getting would be cool. Thanks

[trvo]

15T for 5S, 13T for 6S

OK, must have missed that, thought you were now on a brick config. My bad.

All these recomendations seem to be backing Aurrora again.
Now I know the revo is good but please guys can we not just focus on Mikes free products to you.
Whats the best non Aurrora lipo pack?
What is the flight power 2500 like to fly? though expensive I'm thinking of maybe getting a couple due to their higher C ratings.

Martin, we are testing the packs we have got and right now they are the Align 2500, FP2500 and the aforementioned Aurorra packs.
Trev and I already posted that the Align actually flew pretty good but 2500mah is in all our opinions not enough mah for this bird. The FP is also a 2500 mah and raptorheli2 has already posted his opinions on that pack, although I'm sure he will be glad to provide an update. My understanding is he is selling the pack for reasons of it being to low mah.

We are focussing on the packs that work best so far, to come to a recommendation. That recommendation is that 6S 3200mah works very well, as does 5S 4200mah. Now if you want to buy another brand of the same size I'm sure it will also work out just fine. The point here is to find the size that works best not the brand. As it turns out Aurrora are actually helping us do that and you (and others) are benefiting from it. If you don't like that then I can't do much about it. Other manufacturers aren't exactly bending over to help at this point.

If you want to believe that higher 'C' rating on a lower mah pack will make it fly better then I advise you to rethink that. If you want to pay half as much again for a lower mah pack then it's your money. We haven't said much about the FP2500 because it's been cast aside by better offerings, simple as that.

but here's some maths for you:

2500mah * 25C = 62.5A continuous rating
3200mah * 20C = 64A continuous rating
4200mah * 18C = 75.6A continuous rating

The 3200 6S pack from Aurorra is significantly cheaper than the FP2500 and has a higher continuous rating and more mah. So in theory it will hold voltage better, fly longer, last longer and cost less to buy up front.

Of course it's up to you but to me this higher 'C' rating seems to actually be lower when you run the figures. Unless you are referring to the FP3300 6S....which is a nice cool £140 and doesn't fit in the canopy due to being bigger than a revo 3200.

Maxpoly are thinking about adding a pack or two to the melting pot, if they do those will also get tested, checked for size, weight, compared etc etc. But I'm not going to recommend or concentrate on packs that aren't going to provide the best user experience.

[raptorheli2]

martin, i might have testing packs but my testing and time saves you buying the wrong packs and then we all can get the right packs and pay for them (myself included)

i have said many many times i have FP2500's and they are fine if you must have something else. either that please buy some and let us know as i'm skint buying batteries and stuff for this 500, sometimes you can no gratitude it seems. the reason i'm saying aurorra packs is because it's the ones i have and they work. i can't recommend x or y without trying them. anyone else is free to step upto the plate with testing here.

cheers

Yeh so do I Jason hence why I want all the info not just the info from Aurrora's stable.
I too use Revos in my 450 V2 se & apart from 4 different headspeeds from 4 different packs Im very happy with them.
They are not as bullet proof as I was first led to believe though but if they are the best out there at the moment I will be buying some.
Martin

[raptorheli2]

martin, if you do not want info from the "aurorra stable" then please feel free to buy some packs as i have spent about 300 quid on packs for this 500 already and i'll be HAPPY to sell you a 2 cycle old FP 2500 if you so wish. i'm not buying packs i don't want so if you have other packs in mind please buy them but i honestly think it is a bit of a cheek to ask guys who lhave aurorra packs to comment on things we don't have ....not going to happen mate. also remember we could easily keep this info to ourselves and let you go it on your own. which would you prefer?

cheers

[AdieSmith]

Why not give the tornado 3s 2200s 25c a try you dont get very long but you can also use the packs in your 450. £35.99 each from your local model shop

Thanks again for all the useful input guys but i think Martin has been misread a bit here..

Info on other makes of pack will be good,i am personally going for the Maxpoly 5s 3800 that fits on the top tray fine and is light by comparison to others..

I will back Martin up and say the Revos are not the best,the decent charging system normally sold with them is the real reason i think,decent charging on other packs works for me..I may or may not use Revos on the 500,depends what they come up with really.My oldest Revo 3s 2100 is bolloxed now and puffed,my original 6s 4800 packed up and the 4800 i am using now is not as powerful as my 75 cycle old TP 5000 Extreme but it holds out better near the flights end,my view on them is they are decidedly average and i will personally quite happily try other makes

When i get my 5s 3800 i will post my findings,but again all the info being made available is great and appreciated

[LipolyGone]

Ok so were saying 2500mah is too low a pack size for this bird!
Right so that means then two of my 2100 revos are going to be a waste of time also thats great I now need to buy at least 4 packs that will work with my new heli.
And there would be little point in buying 2200 revos either as they also would be a waste of time.
So that just leaves me with the option of paralelling the revo 2100 packs Is this what Mike has been doing to get to the 4200 mah pack size?
I'm sure in a thread I posted regarding paralelling packs for my 600 that this wasnt advisable for reasons of voltage drop on all of the conections but now were saying this is ok why is that
I am very confused now.
