I figured I would start a build thread. The model goes together so well that there is not much to discuss :thumbup:. But for those people that sometimes breeze through the manual you may miss some items so later you have to unbolt stuff to put them at their proper place. :rolling.

So to kick things off I made a short video of things to take note during the build. and some pictures of the heli next to my 700E which will be going for sale.:peace
I will add more to this thread as I complete the build.

It's not a bird! It's a model, and a very fine one at that!

After seeing the thread at the other forum about people calling it a "bird", I knew I was getting it:rotf. I really thought about reshooting the video because I said that, but lazyness kicked in.:YeaBaby:

Did you maiden yours Kevin?

Got a few flights in on mine already. What a great flying model? (what else would you expect from MA?) Still a little scared to push the stick all the way forward as it is a rather quick model at 3/4 stick. Turning 2100 in idle1 and the model seems real happy with that.

How are your flight times or are you still breaking in the packs?

Great video Zoomtt:clap Any complaints thus far if any? can you post a pic of the two "birds" with the canopy on?

The only thing I can gripe about is there are not that many holes to put tie straps. I actually drilled some small holes just to accommodate tie straps for my wire route. It won't be an issue to other people. I am just a neat freak! Well at least while a model is new:rotf

I will take the pic when I get home tonight.

5 minutes on 5000mAh packs.

Almost done! just need to setup the Vbar and it is good to go. I mounted all my electronics inside. It is awesome. there is so much space. In a crash, the electronics have more protection.

Like I mentioned on my previous post, I drilled some small holes on he frame just to have tie straps hold my wire route. You can see it on the pictures, it is near the Vbar sensor.

There is absolutely, no filing, grinding, twisting, etc. on this build,. Every part went together perfect. I think this is the first time I built something that I did not have to modify something.

The Thunderpower 65C 5000mah packs are a little tight where the wires come out of the battery.You need to squeeze them in as you slide them. However, I am not worried about it since I can charge the batteries while it is on the heli ( I have a generator). Also, I wired up the heli where you never have to take the canopy off while powering up or charging at the field this will be great!

I will maiden it with Mavrikk 690 FBL blades an Mavrikk 105 Tails this weekend, I will come back with some feedback and hopefully a flight video when I get the vbar dialed.

Flying weight for my Whiplash 11.6 pounds.
This is using a BEC no Rx pack.

Here are the electronics.
R8917HV cyclic
BLS251 tail
Gryphone regulator for tail
Hercules Super BEC
Castle 160HV
Vbar full size

I would be scared to charge lipos inside of the $3000 heli.

Looks like a good score on the Health-o-meter! :YeaBaby:

Nice pics, should keep me going until mine arrives mid-nov/dec.

Sounds like 8.2 lbs dry. 11.7 - 2.52(Lipos at 1600g)
700E 7.8 lbs dry with very similar setup(8917, WR Super, YGE 160, Vbar

I would think the Whiplash would be lighter with Direct to Swash.
Better, Thicker Carbon?

Lighter doesnt necessary mean better.

Id rather have a slightly heavier heli with better components (less wear), less flex in frame and less vibrations, over a lighter flimsy heli.

Especially with the power that electrics put out, I doubt an extra 500g or so isnt going to make much difference. ???

I think it's only 200g. If it was 500g no way I would even consider it, it is very sigificant even with one of the new crazy motors, 4525 Ltd, Xera 4530. You can feel a big difference even if it's 200g on a 700 Electric. Stronger is no doubt better, but weight does matter.

Really ? :confused::oops:
I figured if you are running say a KDE 700XF-495kv or Xera 4530 which can do 10kw bursts , or the Scorpion Ltd Ed. 4535-550hv that can do 13kw burst, that 200g would be insignificant.

As long as the extra weight doesnt affect CoG, i personally can see how 200g with that sort of power would be noticed... :confused::confused::confused::confused:

Whats the ETA on a flight video? Your going to have to let me have a pull on that "bird" looks clean!!

This really is not uncharted territory, it's not like the Whiplash is the first electric 90. I learned a lot a year ago from the TDR Forum as those guys were already running the same class motor. Just throwing more power at the power to weight ratio is not the solution. I have tried most of them, Xera 4530, Scorp 4525 Ltd, Scorp 4035-500, 700M, 700MX, and Xera 4035-480.

Given the same headspeed, 2200 as an example, and a given weight, say 11lbs, and 690mm Blades, disk loading will only decrease with a decrease in weight. Power just prevents losing headspeed. Kinda like an 800 HP Mustang, tons of power, but heavy as a pig, and that shows up in handling.

I would take lighter any day of the week over more power.
But 200g is a small price to pay for a stiffer more robust heli.

Close, just doing some fine tuning with the vbar. I was beating on it on the second flight:thumbup: our field felt really small now with the whiplash. This thing is huge in the air.

I am sure you will rock it hard when you try it. :noteworthy:noteworthy

Thanks.. makes sense
I was going to buy some 5000+ packs for the 'Lash but now i think ill run 4000-4500 which are lighter... :thumbup:

4500 at around 700g per pack is about as good as it gets. if you are going for one of the 10kw peak motors, 4525 ltd, Xera 4530, KDE 495. Get the best packs you can, they will destroy an average pack rather quickly.
