YS 120 vs Std Trex 700E Climbout

[lee mister]

my 120 wasn't that far behind, he was using radix 710 and i use EDGE 69O.
the first 2 i was running 1980 head speed 11 pitch and i upped it to 13 on the last witch was worse i think.
i think he was at 12 and 90 percent head speed.

That was a good comparison and tbh I think flying head to head 3d you wouldn't notice much difference at all plus the Nitro bird could do it for about 5 mins longer and be on the ground for less time during recharge/refuel.

I bet you knew that was coming but I just had to. lol

i knew some one would say it that's why i didn't lol

As long as you know the truth it matters not a jot. ;-)

I bet a YS120 empties the tank quicker than 10-11 min

Probably but it will still have longer flight times then a leccy and less time between flights.

I really like leccy heli's btw much less hassle I just need the longer flight times and cheaper packs.

Sorry I don't know much about nitro motors but is this the ys120 top of the line motor and was the electric motor the standard align job? If so that's quite an eye opener! I had been told the ys120 was a match for the kde/scorpion le 10kw motors!

electric in big helis is a pita IMO, i have YS120's and i had an E7. the E7 lasted 3 batts and i sold it. i had a scorpion motor in mine FYI (E7) and i can put hand on heart and say the YS120 is equal to it after about 1.5-2 mins and after that the YS will beat it easily. for me it is a no brainer, anything bigger than a 600 for me is nitro.

the E7 was dead for me about 4 mins and the YS had about another 3/4 left in the tank.

edit-btw electric easier IMO is a myth, the amount of gear you need to take with you to charge a big leccy is a joke. it maybe better if you didn't have nitro aswell (i.e me) and need to lift chargers, batts, balance leads, adapter leads plus the usual nitro stuff. another thing you need to consider before making the change is you need to wait an hour to go flying, not ideal after work but to each their own.

cheers

I was thinking more the setup tbh as I had a 600e the original one and ran it at either straight90% or 100% throttle so no throttle curves and no tuning required just one less thing to worry about.

My heart still lies with nitro machines though but I do like the wee 450's :-D

I have to agree.
Its been over 2 years since i have flown nitro,but with such short flight times on the 700e i have decided to set up a 700 with an os105.
Its a big gamble for me,as i was never satisfied with the consistency of the older generation 90 size engines.If i can get it to work, it will offer me long practice flight times,however if i am still not satisfied with the results,i will stick to the 600e size models,untill lipos have a little more to offer.

its a simple solution.....just have both (or at least one nitro). Then you get to fly the nitro whilst your batteries charge. great bit of fun with the video

[Mike W]

TBH ... Thats not really a way to test elec vs nitro .. Only way to do it is to get 2 pilots do the same manouvers and see who lasts longer and towards the end of the elecs flight can actually do the manouvers the nitro will still be doing ... Oh and also why not some power climbouts whilst the battery is not in a fully charged state ... Yes Elec is easier and cleaner but for me half the fun of flying is messing with smelly nitro engines

[Planehazza]

yeah not wanting to start another electric vs nitro arguement, but from the go, electric has more power. However, as the flight progresses, nitro gains power to weight (tank emptying, and increasing leanness), whilst electric looses it due to voltage dropping.

Agreed, i like starting and fiddling with the nitro stuff. Hate the mess though. If I had a spare couple of grand, I would invest into the electric scene, but it wouldn't replace nitro

This is not sticly true if you are using a correctly setup governor and the correct gearing

I personally dont think that either is the better option it is really dependant on circumstance. If I fancy 3 or 4 flights I can just grab my 500 a pocket of lipos and TX and im out the door which I can't do with a nitro but equally I cant fly my Electric for almost 10 mins. However I do feel some of the nitro comments have been somewhat exagerated here to make out it IS the best option period. For example, you do not have to wait an hour before you go flying. I can happily have a couple of lipos charged in approx 30 - 35mins at 2C and this is using a 10S and not one of the newer high power chargers.

I have both electric and nitro and for me they complement each other very well. I get great flexibility and cheap running from the electric and great flight times and prescence from the nitro although it does cost me more to fly. By running the two I get the best of both worlds a bit like composite materials lol

This was my thinking after I started flying the 500 and found I was flying it as much as my others. So if half of my flying on a given day was electric I could justify the other half being a 90 nitro instead of a 50 :-) But it's also nice to have something smaller than a 90 machine as it does get a bit tiring to lug around sometimes. So the 500 tends to be a constant and what I fly along with it varies.

I am curious what motor is in that 700e though as I am doing an electric conversion using an Align 700M motor.
----I just saw over on 'another forum' they mentioned it is the MX motor.
