A bunch of problems and solutions with the 700e

Well done on the Maiden Sladex, btw.

Fyi, I run 1xPair Aplus 5200mah 65c and 3xPair Turnigy 5000mah 40c. With both I can can get around 6mins minimum, give or take. I only fly sport.

I find with 4 sets of batts, it can keep you flying batt after batt easily. You can have a batt charging all the time and fly and rotate accordingly. I fly my plank in between to relax a little too, which gives more time to recharge the 550 or 700 batts anyway.

I'd just buy some more batts for your 700e, personally, rather than spending a whole lot more on another heli at present.

Just some info for ya to think about before spending up on a Nitro, as they also have their 'cons'.

Well i said the same thing but my dad said instead of paying 200$ for a good quality
battery he would instead just buy a nitro as well. The guy who fixed mine is selling one for 999$ with a ton of upgrades.

Well, it's your money but maybe you should just concentrate on learning all about the 700e you've got first. Eg. FBL setup, mechanical setup etc before introducing another component(Engine tuning) to deal with at this very early stage of your heli career.

Yep. Once i am confident with the 700e, i will be taking a trip to the lhs.

Nitro's are a little more complicated than electrics. Plus fuel costs every flight. Just get yourself few sets of batteries. I like taking a brief break every few minutes so electric perfect for me. Might want to research the pro's and con's.

One thing that sucks about nitro sometimes...

I plan on keeping my 700e for a long time. I know nitro is different from electric but i just really hate 4 minute flight times. But in nitro the sound is alot more meaner and the smoke trail is really cool. I will look at the pros and cons again

Unless you fly like Alan Szabo, which I doubt you do, with 5000mah packs you will get more than 4mins!!

Personally, the nitros sound more like a toy to me because of the model engine noise.

I've owned and run both 700E and 700N. Both were fbl. At 1950, which is pretty much what you get with nitro, I got seven minutes on either. Of course with e-power you have the option to crank it up, which is what most people do. That's how you end up with four minute flights. In my experience, cost of ownership is also much less expensive with e-power.

.....why continue with toys Sladex? Just get yourself a Turbine and be done with it!!!!

+1

I say again, try 5 or 6 min on your timer and see what you put back in. For hovering and slow forward flight I doubt you will be putting in more than 70% at 6 min

Well my 700e wont be flying any time soon. My AC6 Thunder charger just blew and now is saying "SHORT ERR"

That sux dude, but really that's not the charger you'd want to be using for packs of this voltage and capacity. You really need a 200W+ charger and power supply combo and even then charging each pack will take at least half an hour running flat out.
An AC6 outputting at 5A x 25V is only 125w and it will take at least 45 min to charge each pack and you will be running the poor thing ragged, I'm sure this is why it failed on you.

My set up is cheap but does me well.
Power supply 23A x 14V: $70
Charger Turnigy Mega 400w: $60
parallel charging board: $15

I can charge both flight packs together within an hour without pushing this set up too hard.

[blackout19]

A 50 watt charger like that will barely pull 2 amps on a 6s pack, which is nearly 2 and a half hours per pack, or 5 hours to get one flight pack charged for your 700... That could explain the 4 minute flight times, I doubt you are getting full charges. (assuming this to be your charger)

That is defo something you need to upgrade to make your ability to fly a realistic proposition.

[Bonkievan]

Yep. totally agree with the other two posts above Sladex. Imo, charging setup is equally important as the heli, as without a good one, you wont be flying much anyway
This is a part of the hobby that many overlook when moving up heli size quickly.

When moving up from my 450, a member at my 'field' said 'don't get a bigger heli unless you upgrade your charging setup(only had a 6amp ac/dc). Get something that will be good enough even if you decide to go 700 size or even 14S. Otherwise, it's a sure fire way to get frustrated'
Wise words.

I ended up getting a Hyperion 720i super duo and a Efuel 60amp X variable 24V power supply.
I can charge 2 packs in around 30-45mins depending on C rating, More than enough power for my applications.

I think you need to head down to the LHS and spend your money on a new charging setup before giving up on e power. If you do this you'll enjoy your 700 much, much more

You can make a great power supply for under 50 bucks using new parts. If you scrounge server PSs it can be almost free. And educational...

[blackout19]

I've got 2 of these wired in series which cost me about 30 bucks including shipping. There is a thread on RC groups about modifying these for the cost of a bit of wire and a couple of banana plugs here and a specific thread for the DL380 PS here

One of those, with 10 minutes worth of soldering, can give you a 575w 47amp power supply.

[terrabit]

My setup is 2x FMA PL8's and a Meanwell RSP 1500-24. It's all the power I'll ever need. And with the FMA fused power boards it is probably the safest setup available. For example, a short involving the charger is not possible. It'll just beep and say "nice try dumbass", or something like that.

Just make sure you get a strong power supply to go with it. A powerful charger is worthless if your power supply wattage is too low.

I use these two and love them, routinely charge two 5300 6s packs on the charger and 3 2200 3s on a second charger at the same time. I know you're fairly new so not sure if I suggest para charging but with a 12s setup you can save so much time. If just doing the 6s packs two at a time you can probably go lesser on the power supply like this model.

You bought a 'big boy' helicopter.. Get yourself a 'big boy charger'. I wouldn't spend 150 dollars for a 300W iCharger.. That's crazy.. Take a look at the Powerlab 6 (or 8).. The Powerlab 6 will put out close to 1000watts with a 24v power supply.. If you get it from EPBuddy, you can get a free parallel charge board included.. For 175.00.. No brainer..

Agreed. But I'd suggest contacting David at ProgressiveRC.com instead. The support he offers before and after sale are second to none. And he has everything you could possibly need.
