Trex 600E Pro Supercombo

[Stanley Speel]

Hi,

I've just bought from Fast Lads a Trex 600E SuperCombo - which will be my first build

The things I've bought are below:

-RCLogger Digital Pitch Gauge 209288RC
-T-REX 600E PRO Flybarless Super Combo No ESC 16017 - NO ESC
-Deans Battery Series Harness Comp' With Deans Charge Lead O-LGL-CLDNST
-Hyperion Rx Battery Pack LiFe 6.6V 2100mAh 5C HP-FG305-2100-2S
-BSI Insta-Cure Super Thin Super Glue 1oz BSI102
-Deluxe Swashplate Leveler T-REX 600 (Silver) HR1025
-Quantum Heat Shrink Tubing 2.5mm 1mtr red and black Q-HS-0001
-Novak - 6in Heat Shrink Tubing Asst (24) - NOVC5851


I also got a castle ice2 80 HV esc, and I still need to buy the satellites. This is all I have to assemble it, along with 1.5, 2.0 and 2.5mm hex keys, a soldering iron, and that's about it. If I've missed anything out please can someone let me know

I'm going to be using deans connectors (is this a bad idea?), and I was really hoping that I could use two of my 500 packs in series - I have 2 2600mah heliguy rapidcharges and 3 turnigy 2650 mah ones. However, I've been told that these are too small and that I will need at least 3000mah. Is anyone using 2600-2650 mah lipos?

Many Thanks

Stanley

you can use those packs but you will have less flight time,i would take the opportunity to get some ec5 connectors,you wont look back,IMO,nice machine,was going to get one but im holding out for another model

[sacko]

Bit of a spend up then

Seond the above for EC5 connectors.

3500mah is ideal according to all the threads I have read, so a bit too smal but useable.

[killer4557]

using 2x 2650mah packs will work but it will cost you in flight time and may effect the COG of your helicopter

[theglennster]

Dont forget the blue loctite, and strip the head down first. Dont trust stuff assembled from the factory some of it may have no loctite. My 700E grips evem had lube on the bolts!

Deans are OK I have used them for ages but recently bit the bullet (gerrit ?) and swapped everthing over to EC5 connectors. If you are gonna change its best do it before you get to many packs as swapping them over when you have 10 or more packs costs a fortune

I cant see why you 500 lipos wont work just keep the packs well forward and your flight times short until you find how much you are taking out of your packs. Maybe 4 min flights depending upon your style. You may have to go bigger packs but it will cost you nothing to try your smaller packs.

[Zeeflyboy]

4 mins would be pushing it to the absolute limit imho...

I have a timer set to 4.5 mins (when it goes off I come in and land fairly quickly) and burn around 2,500mah per pack (using 3300mah packs, so about 75%). I know you already know what I think, but in my opinion 2600mah is just too small! 3300-3500 is the sweet spot for me.

They will physically work, but you'll be flying for like 3.5 mins and may find it tail heavy.

It's a great heli, but you need to feed it right

Edit - oh and switch to EC5s already!!!

[Stanley Speel]

Thanks everyone for all the helpful replies. I will probably switch everything to EC5s - however over £20 for 10 EC5 connectors is a stupid price, and I will probably ruin half of them as I'm not too good at soldering.

Being a student, I really can't afford to spend another £180 on lipos (that's buying 6 turnigy 3000mah 20c ones from HK germany), I've only got about £50 left to spend on helis after getting 2 spektrum sats - and that will probably cover one crash on the 600 if I'm lucky :P.

Get them from Hobbyking, they are really good imo.

..and works out at £1 each delivered.

[Zeeflyboy]

Yup, get a load from hobbyking... the ones they sell are pretty good in my experience.

Once you switch over you'll wonder why you spent so long with deans lol... just one tip - don't bother with a soldering iron, get a small butane torch and something heatproof to hold the bullets (i just use a small clamp). Heat them up until the solder melts and forms a little solder pot about half full, then with the heat still applied insert the wire end, the solder will probably harden at this point due to the colder wire. Keep the heat applied until the solder remelts around it and you have one bullet proof solder joint. If you want to do a really good job, just lightly dip the wire end into some flux first.

So much less frustrating than deans, handle more current, and easier to plug/unplug.

If you can't stretch to new batteries for the pro (and I do sympathise, they add up fast), then what you have will work, just be careful not to fly too long as your batteries won't live long otherwise and you'll end up having to buy some new ones anyway. Just keep in mind that some good sized lipos need to be on your shopping list in the future!

If you dont want the tail to blow out, you either need to mod the gear ratio or change the tail blades to 105's. Your other option is to run the hs at 2500 rpm+ and with 2650 batteries your flight time is going to be 3 minutes or less at this hs!

Paul

p.s. been out with mine today its awesome!

[Zeeflyboy]

Paulo - I've had no problems at 2,300-2350 governed... using stock ratio.

2200rpm sees the tail start to step out for me. But either way, flight time between flat 2500 and governed 2350 is going to be negligible, so your point still stands regarding flight time.

As an aside, the Rail R-96 blades really locked down the tail - the thicker profile and aerosol design must generate more lift I guess... even at 2,200 rpm it seemed to behave much better but I didn't spend too much time on it, 2350 is my perfect range. This heli is designed to run a high head speed and it flies absolutely brilliantly at them. My personal suggestion is to run it as designed!

[Stanley Speel]

£180 was the hobbyking price for the lipos - these ones

I might just see how it goes with the lipos as I've only been flying for 4 months, and I'm still at the circuit flying stage , so I can probably live with 4 mins. I wasn't really planning on using the governor either.

[ChrisB]

Chap at our field just hovers about,stock setup,very low headspeed under 2grand and he gets 7 mins plus from 3300 packs.

C of G should be ok,just mount them as required on the sliding tray.

The 3300s in your link are the ones I use,been beating the crap out of them since last year (2010) and they are still going strong with enough power to scare the $hit out of me in the 600 pro and 6hv.

[sj257]

I'm running 3300's in mine and use about 2300mah in a typical 6 1/2 minute flight. Thats flying vith a vcurve in IU1 of about 75% throttle mid stick ramping to 95% at either end. And +/- 12 degs of pitch.

Your success with smaller batteries probably depends on your flying. My flying is maily aerobatic into mild 3D (I think). No smack down stuff. I use to get about 8 minutes from th esame capacity just cruising around.

So, if you don't want to hammer your Lipos and don't mind a modest head speed then you could get 5 1/2 minutes crusing or about 4 1/2 minutes of loops, rolls and flips etc. But as others have suggested, start at say 4min and see what you draw.

Have fun.
