I am by no means a world class pro pilot but I think I'm average at least. I am open to others opinions though.

 

Trust me Emil can do piro flips and piro tic-tocks.

Min you fly great!

Nitro has probably <4kW, electric did not require much more.

Sometimes I fly flat 100% throttle with 450, 550, 600, 700. In general I do not feel need for stronger setups.

 

There are certain moves that require constant cyclic and alternating collective that will not be possible for a low powered setup. If it can make a high powered setup beg for mercy just imagine what a lower powered setup would do.

 

I just ordered new motor for Gartt 800 :/

 

Nice flight @Min

 

Min your way better than average.. Don't sell yourself short.. You just gotta say it.. "I'm Min and I'm an awesome rc heli heli pilot"...

Looks like no one wants 700 lighter than TDR. : )

I will not both you with this project.

I love to fly it. Who cares?

 

A 700 lighter than TDR is already out there, Logo 690SX.
Another 700 will be coming out soon that is designed for high power and heavy setups but still remain comparable to the TDR in weight when both are without packs. The idea is to have the helicopter super light and load it up with batteries to prolong the flight time however keep the sensations procured during the flight the same as a normal heli by having similar disk loading.

 

Logo you mentioned is in fact stretched 600.

Building cost of my low weight 700 is much lower.

Not everyone wanting to build 700 is willing to pay $700-$1000 for the naked airframe.

I know how to make this cheap frame reliable, agile and smooth.

Kit is only small part of the final cost. Electronics, charger, new power supply, lipos, replacement parts in the case of crash will make Logo $3-$4 grand "toy" fast.

I can show how to divide those costs at least by half and not sacrifice performance.

All those "clone wars" made me rethink if my presence at Heligods is welcome.

 

The 690SX is not just a stretched 600, I think you have gotten is confused with the older 600SE which ran 690mm blades but was just a 600 with a longer boom.
If you can prove to me your budget low weight 700's can handle a scorpion 4525 ultimate motor just fine then I will be very impressed and seriously consider buying one. This means it can take a Kyle Dahl style smack down with out any component failures at least for 5 flights while flying the 4525 motor. This is the standard motor for high performance 700 and is the one included with the 690SX so please don't think I am being unreasonable. If you have trouble sourcing a motor I am willing to lend you one of comparable specs if you are in the melbourne area.

Things the heli must perform:

• Light tail strike with the grass
• Rapid tail direction changes without hesitation
• Full pitch rainbows without tail kcks
• Fast tic tocs with out tail kicks
• Fast hurricane and funnels without tail blow out
• Overspeeding autorotation

 

I do not know much about motors but I'm sure @xnovamotors support will be willing to point out why a Turnigy SK3 cannot be comparable to the Xnova XTS series motors

 

Min you are right I was thinking about Logo 600 SX.

I can put Scorpion in this stretched frame especially for you and record a video. Unfortunatelly my flying skills are far from master level but I can pushing it hard.

To give you some clue my colleague build 5kg 700 with gasser engine on HK600GT frame. He used RJX FBL head and smacked it at highest RPMs motor could deliver.

As for 700 it was very heavy and noisy but surprisingly it did not explode.

He found that weakest point in this setup was front TT umbrella gear. He use one from 600 PRO of course.

My electric is 2.95kg without lipos. At least 1kg lighter. I discovered how to make those Gear much stronger and did not strip them for at least 2 years. At my old videos you can not see piroflips but fast forward flight is also tough for airframe. Check agility and acceleration on my old videos.

I do not like SK3 motors anymore. They have horrible bearings. If you replace bearings they have one advantage... low weight. Gartt Motors are cheaper and far better. Trust me I killed few SK3 Motors and use few Gartt motors. I ordered Scorpion Ultimate recently and plan to test it in 800.

 

No more information will be disclosed until a later date.

 

Logo 690SX seems pretty heavy:
RTF weight4,8kg (with 5Ah 12S lipos)

 

4.8 - 1.6kg for batteries means 3.2kg. Stick that high power setup in your 700 and you'll end up with the same weight.
