Yea Charlie told me he was going to call it that and I said "YEA man!" Good idea :)

I got 5 more flights on it. I was going to do a video then a friend of mine who is a devout Mikado pilot showed up (2-L14, 1-L10).

So I thought this would be a great opportunity to get his opinion on how it feels since he's used to flying the Logo's.

He said this was a major improvement over the old setup and liked it a lot. We agreed that this was how it should have been in the first place.

I asked him to fly his normal routine with my 550.

The flight lasted 5:15, only used 2196mAh out of the 3700 Flightpower packs. At 5 minutes it still had good power to tictoc and was not falling off in power. So a longer flight is still possible. My guess flying like he was we could have gone to 6 minutes easy.

All this on 550's.

Oh, and I lost a 2nd sleeve on the one way during this flight. It was locked up at the end. I may just machine my own because the stock ones are getting chewed up. Its possible the metal is not hardened properly.

Enjoy !

Nice video Matt! It is cool to see all the different styles you video. That was a nice flight!!

I was just comparing the photo of the HFE frame with that of ther logo 14 and noticed that the logo only uses 2 main shaft bearings as opposed to the 3 on the T600.

I wonder if it would cause any issues to drop off this lower bearing. Could save more weight and possibly cut the frames down even more. The lower part of the frames on the logo 14 barely exist hehe.

Thanks Will.

What about durability? With the 9650's as direct linkages, isn't it much easier to strip the servos? And are those servos really strong enough? And is there anywhere to mount the electronics? I hate mounting things on the sides.

Based on the weight, it looks like the A123 7 cell packs might be doable on this frame and still squeek 4 minutes of flight time. Not bad for cells that can be charged in 20 minutes.

[Finless]

And are those servos really strong enough?


Well the Logo 14 folks have been running them for a while now so I have to assume they work fine...

Ron,

The 3rd bearing is needed. The main shaft is to long on a 600, without it your main gear would flex away from the pinion. Plus weight loss would be minimal.
Anyway mine is 6.15 - 7.0lbs currently using the stock 600L on Flight Power 6s 4900 and flies very nice and "LITE" :glasses2:
I can only imagine how it flies with a Neu motor or something truly efficient.

Just as bob said plus I have a dozen or so flights now and matt has probably 2 dozen flights on 9650's and we both have not noticed any issues at all.
My cyclic response seems just as good (Fast)as it did with 9451's but the heli just feels better being lite!!!!

For those wanting kits for Hitec 5245's I should be able to start the shipping of kits on Friday I am awaiting on parts to arrive by thrusday I have made that kit available on my web site if you would like to get on the waiting list with a preorder

Thanks

Charley

[rdespins]

Orders in for the 5245 version.

yes, but what about durability in a crash, with the direct linkages, won't you easily strip gears now?

And where do the electronics go?

[Rotorworkz]

Well nothing is guaranteed to be durable in a crash. Im not going to say you won't strip gears.
The eletronics go anywhere on the frame you want imagine your stock frame, with the motor on top this now leaves an entire void now

Heck I almost have enough room now to have an aircraft hanger to land T-rex 450 :wink:

[MrMel]

Any servo will strip in a crash if its hit directly, and yes, with direct linkage its a bigger chance of that happening, 9650 gearset's are cheap though, I always keep a good supply at home :)

For strength and durability inflight, Im using 9650 on my Logo 14 with Vstabi where you have direct linkage from the blades->swash->servo (no mixing anymore), and they hold up to that without a problem.

How about a setup that works with the JR DS 821s? Or are those not really up to the task? I'm using a DX7 in my 600, and thought the servos that came with it had pretty decent specs?

Thanks,
Lee

[WillJames]

They are way to big for the mainshaft to fit between I think. The 9650's allow I think 2mm clearance. I have heard they are ood, but nobody wants to buy them NIP for some reason...

[SteveL]

Charley let me fly it today and all I can say is sweet.
It made me put my 50 nitro right back in the truck.
:noteworthy :noteworthy

What does "ood" mean?

I may use them with my Stock frame for now, and order the Rotorworkz kit and 9650s for upgrading later.

Thanks,

Do a search on those servos. There have been a few heli related failures for DS821's. Helis are really hard on inexpensive digital servos due to the constant demand to hold position.

In planks its more of a deflect then back to neutral type use. They are great in that application. In helis the constant load and fine inputs fry the controller boards. Sometimes in a very short period of time.

[robl]

What is the weight difference between the g10 and carbon fiber frames?

[rdespins]

Charley mentioned roughly 15-20g per side

[robl]

g10 is heavier I assume, so 40 grams heavier?

[rdespins]

About that, yes.
