No, no, not you Big Fil, I didn't mean that at you. I meant The "ugly" design of the heli probably falls 50/50 at the feet of the designer and Ralf combined or what ever percentage.

All I meant is the weight of it is shared by both of them.

I hope and pray the Logo 700 will not look like the Xxtreme. Dave let the cat out of the bag and said there will be a true 700 machine, and I hope it looks nothing like the above.

That is the problem with that thing being so big.

I run Jive 80+HV, Fullsize Vbar and Two sats.

That thing has fullsize vbar, esc, BEC, step downs, fans, phase sensors, step ups, step sideways, skid stop inverters and the list goes on and on and ...

Do they wonder why people don't like it? Geez... All that happened when they took the canopy off is manufactures laughed their heads off.

Sorry to ask but what was so secret that these pictures could not have been posted before ???

haha, I agree. I remember hearing someone say they were keeping the canopy on becuase when it comes off we will be blown away by groundbreaking engineering. Hmm, computer fans...amazing.

It will make a great 3D/camera ship.

I hope and pray the Logo 700 will not look like the Xxtreme.

The Logo 700 and the Logo XXtreme are the same thing, are they not?

No. There will be a true 700 dave said. The Xxtreme is not it.

My feelings regarding frame design:
1/boom supports to main carbon side frames seem to be bolted to the very edge of the last 5 or 10mm of frame.
So in the event of a crash I think the boom supports/struts will snap away from the main carbon frames,resulting in new side frame,and what will be the cost of these,quite high I assume.
I will once I buy one, machine a simple 30mm t6 aluminium plate that the boom strut/support bolts through,and this plate will be additionally bolted to the main frame in 2 points.
Cost for plate will be very minimal,about an hours work,and for me personally will add a level of improved strength as I feel that these will definately suffer in a crash.
2/landing skids to main frames look weak,and if you look at the photos carefully does It look like there has been a repair in this area already on the xxtreme.
I would machine a t6 aluminium plate again either side to strengthen this area,similar to the aluminium plates that are seen on the align trex 600s.
Why have there been so many cut outs of the main carbon frames,if you look at the photos,in quite a few areas the carbon has been cut away to almost within the last 10mm of the edge of the main frames.
Why didn't they leave as much of the carbon frame intact for added strength,I don't think this heli would suffer from an extra 50 grames of carbon if left in place.
Motor cooling:
I've been building helis for 20 years but am no expert on electric motors but if an in runner motor was used you could put a huge finned cooling plate around the motor,like the many huge aluminium types we see on performance personal gaming computers.
I feel that most helis have there weaknesses,but I enjoy adding what I find is necessary to improve them.
Example on our logo 600s we have have had many rip outs of the bolts attached to the plastic main frame to landing struts,on crashes,hard landings,which resulted in snapped plastic frame tags to struts.so we now change these bolts to plastic ones so they shear off in an impact rather that trash side frames.

Personally

I always thought the regular Mikado canopies were ugly. I like the extreme canopy and look forward to an 800 heli! I already have 3 90's so why not up the ante!

+1 on the canopy

Scale fuselage for it?

This michine is very ugly. It looks slapped togather at the last minuite. The blade grips look like old lago blocks? LOL! I'm a big fan of Mikado and logos. Sorry but it is how I feel about the xxtreme.

T-rex addict. Hey how did that 7HV get in there? Gobble Gobble ? TEAM S.E.M.H.P.

@jprconstrution,

Your comment, "It look like there has been a repair in this area already on the xxtreme."

Not the case. I think what you are interpreting as a repair, is nothing more than fiberglass dust that accumulates in the area, from the canopy mounting and positioning itself on the front skids (as with all Logos).

"...but am no expert on electric motors but if an in runner motor was used..."

The reason out-runner motors are just about exclusively used in helis these days, is that in-runners don't have the torque needed, and to get that torque, a gearbox is needed. It's been figured-out long ago that although not the perfect situation, out-runners are by far the better choice for R/C helis, taking into account all the pro and cons of each motor's design.

I'm waiting for IRCHA xxtreme's demos to make up my mind,
But with the usual incredible show that Mikado's pilots put on at that event, I probably will be easily swayed to buy one

Flying helis isn't an activity, it's a state of mind.

in-runners don't have the torque needed, and to get that torque, a gearbox is needed.

About 99.9+% of our helicopters have built-in gearboxes, in the form of a main/pinion gear. Given this, most quality motors, regardless of their stator orientation, can be geared for optimal load and torque.

In my limited experience running inrunners in helicopters, there was not one time I ever recall thinking to myself "man this inrunner motor has no torque".

To get the torque out of inrunners they need to be geared right. If you can get them spinning over 40,000 RPM you can get very good umph out of them...the Xero G heli is a great example of this...still one of the best flying helis Ive tried.

I know the design concept with this new helicopter was to make "the drivetrain bulletproof", but it looks to me like the airframe is very fragile. Looking at the photographs where the landing gear mount, it looks like there is a lot of thin strips of CF which will easily crack.

Not trying to get into the "build it to fly or to crash debate", but it does make sense to reinforce areas such as where the landing gear mount to the frame so that one side of the frame does not need to be replaced with every hard auto.

Adding more weight to this heli is what it doesn't need (to me), Looking at the front of the heli and all the extra frame and space, well maybe it is for cg but I don't see the reason for it and the batteries can be moved forward to compensate for the front being cut.

I miss mine , one of the best helis I've flown and that thing was fast.

Team My Wallet.

Inrunners almost always require a two stage transmission, the weight and extra drag makes them less effecient.
Simpler is better when it comes to heli designs.
Typically inrunners also run hotter than a comparable outrunner.

Neu motors are inrunners, are they not?

yes, they are.

and they are very good motors.
