Trex 800 for 3D?

[Helimaddan]

Hi guys,

I've had to step away from the scene for a while (new addition to family) but I'm ready to get going again,
I've decided to sell up a lot of my spares and nitro bits as I'm going fully electric,
Rely fancy the 800 size machine but don't know all that much about it tbh, so I'm just after some opinions from anyone with time on the 800 class in particular it's suitability for hard 3D.
A suitable platform or is it more suited to photography work etc and maybe I'd be better served with a 700?

Please fire away with any views you have I'm interested in all....
Thanks, Dan

Did you watch the videos of the TT E820 by Nick Maxwell, that one seems really good for 3D on an 800 class.

Remember repair costs will be higher than 700

Thanks lads, we that certainly answers the ability of the class question, a lazy back yard flight lol

To be honest the costs are the biggest factor I'm considering, I'm very fortunate that I can get batteries at a very good price so there not to much a worry, but I know repair costs and charging station costs are going to be high.

But the air presence they have is so damn appealing

Anyone actually flying one at the moment, what's your average cost for crash, where all the usual suspects need replacing?

These machines (IMO) should be run on 14S to get the most from them if doing heavy 3D. They'll kill packs in no time.

If you want a good reliable performer, just stick with the 700 size isn't everything as they say!

Just to throw out a few thoughts here, there are a few 700 size helis that have quite good presence and are a bit on the large side of the 700 class, these would be the Compass 7HV, Logo 700, Rave ENV and Alees Rush 750.

We have a few Logo Xxtreme 800s at our club and crash costs are pretty steep, one of the biggest being blades.

No but blade noise is

I have a 800 Trekker (For sale, Shameless plug :P ) and from flying it I can honestly say it's great at hard 3D, anyone that saw it at the AIR helifest will back me up in saying that, admittedly you won't be able to push it as hard as a 700 but thats just common sense.

If you were to get one I would strongly suggest putting 780 3G blades on it (instead of the 800 3G blades) as this will make it a bit more manouverable.

and regarding the comment about the 800 on 12s is a pack killer, The Trekker was/is running the 850MX 490KV Dominator on 12s (Normal - 1650, Idle 1 - 1850, Idle 2 - 2000) and after 4 mins I land with 30% left in my packs and I don't hold back at all with the Trekker.

Helimad if you have any questions about setting one of these up please don't hesitate to send me a PM about anything

Cheers,

I think what he meant Alex is that it will have more strain on 12s packs so will likely shorten their life span. Using a larger motor that these big beasts need will defo pull more from 12s packs than they can handle and this would show high peaks of motor amps being pulled and batt voltage dropping.
14s is the way to go on larger than 700 for the duration.

Im thinking of a Trekker. I dont fly hard 3D so I got no issues although they do seem slower than the Goblin 770 which is awesome btw The Xxtreme was awesome but sluggish


Dani, those who say size isnt everything, well you know where im going with this lol.

[Paulice]

6s is also fun on a 800 15 mins flight time and still capable of more 3d than i can do

[Jamin_00]

Cant compare that Paul.

Running 6s you will be running very low headspeed and pitch. Run this the same (which you cant) and it will puff the pack in a heartbeat and the ESC will prob blow up and the sky will fall too

[Alex Hawtin]

Ah well, I know what I ment

Trex 800 for 3D?

some interesting points made here and certainly giving me something to think about.

Alex thanks for the offer of help should I go for it I might well take you up on that.

Think I'm going to have a look around the other 800 class machines and then see what direction to go in.

Parts for the 800 are cheap, as is all aligns stuff, in my view. the only cost that is hard to bear is the price of the 800 blades

I don't know about cheap exactly it all soon adds up, other than certain parts there is not much difference between day 6,7 & 800 sizes.
But as you point out the blades are crazy money, ESP when they only cost a fraction more to produce than a 450 blade :-(
