I flew one with v bar and jive and with the batteries used 6s 5000 45c nano it was around 12.5 and with thunder power 65c 4400 it is 11.88 well around that.

There was something I couldn't put my finger on when flying it but it is the cg, I had the same feeling with both helis, the one I flew with a 560kv is WAY over geared this is why it felt so powerful and didn't realize that, with that motor you would need a 12 tooth pinion.

The 520 motor would need a 13 and if a 450kv motor was used then the 14tooth that comes with the kit would have been better to run 2100 headspeed, or a 470kv, when I flew with the jive and 520 motor the throttle curve needed to be down to 50% just to get a decent headspeed which was still to high.

The head also had play in between the blade grips and the head block and to fix that the dampners had to be turned around on the 3 whiplashes I no of

I didn't have to put the batteries in or take them out, but it seemed to be a hassle if you don't have smaller packs like 4400 or tp5000 gen ace would be good in 5000.

A few things the user can not control is the pinion and cg, it would balance out but you would have to add so much weight or move it around so much it would create more hassle,

I did fly a 3rd but I wasn't comfortable flying that and doing more than hovering. All of this is just what I have no, and in me being honest I haven't flown one with a proper setup (not because of the user).

I did not have issues with the head slop, but I did with the cg and the stock head geometry.

My vbar file came out with much better numbers when I swapped the outer and inner swash balls for the 6mm quick uk ones. I am using mikado arms with the ball in the middle hole (17.5mm). The heli felt noticeably better after doing this.

I am running a pyro 700 450kv right now, but would love to try the 520kv w/13 tooth when available. The heli has plenty of power, not monster power, but enough to do anything you want with some pep.

The cg issue is really gonna be a deal breaker for me though. If MA does not address this issue, I will most likely be posting my whippy in the classifieds. Moving the rudder servo forward more or even just angling it more horizontal looks like it would solve this issue.

OK. I gotta ask

The CG is off ever so slightly that changing the angle of the tail rotor servo will fix it? And you will actually sell it because of this? Seriously?
Did you ever see what it takes to balance a 700E?

Moving the tail servo will allow you to position the flight packs farther to the front. If you would even take the time to look at one or at the very least look at the manual, you would see that the servo is what stops the flight packs. Geez, maybe you should lighten up a bit and think before you are so quick to defend.

Yes that is true the tail servo is in front of the heli at the nose and is inside.

I have no reason to defend and in fact I am not defending. I don't even own one but it always strikes me as odd when a threat like this is laid out on the table.
If MA does not address this issue, I will most likely be posting my whippy in the classifieds.
When the problem is as simple as

.

To me that sounds like the difference in various motor weights. How should MA get the CG perfect when motors and batteries carry different weights?

Don't take my question personally or as an attack. It isn't meant to be but I alway find threats like yous to be odd so I was just curious.
Would you really sell such a nice machine if MA didn't respond to your statement? How would you like them to address the issue? Seriously?

BTW, I have looked at a few and flown a few.

It was not meant as a threat. I just had high hopes for this model and am disappointed that the CG is off with the only fix being adding weight to the model.

And as far as my reply, I guess I get on edge in this forum as it seems every time I bring up a concern I get told just to sit down and deal with it.

Thanks man. Like I said, I was just curious.

But it does bring up a good question. How do you get it right for all motors and batteries?

I gotta ask what does it take?

Simply allowing enough room for the end user to position the packs where they need to be. There are a lot of cool things on this machine and the overall quality is nice. Hopefully MA will address this one annoying issue.

I am curious as well. Isn't there a way to move some of your other electornics around to get it to balance? Like maybe moving your fbl controller, rx, bec/rx pack. I have heard some other people complain of this problem and then they moved some stuff around and the machine balanced.

Hams, I guess you have never met rstacy, because if you had you would know what a nice guy he is. I have never seen him tell anyone to sit down and deal with it. In fact he would be the first guy to try and help you resolve your problems. This is not an attack on you personally so don't think it is please.

All my electronics are up front. I fit some gens ace packs in (short in length and taller) and it helped, but still tail heavy. The only way I can get it right on is when I shim the front pack down enough to clear the tail servo. Problem with this is I can only use one battery strap. I don't want to cut the frames to move the slots for the straps.

FBL controller, receivers, BEC, ESC are all as far forward as possible. The motor (Xera 4530-500) is heavier than average. The ESC (Jive 120HV) is lighter than average. The packs (Voltz 6s 5100 45C) are as far forward as possible against the rudder servo. My customer does not want to run a separate receiver battery. He prefer the simplicity of a BEC and wanted to keep the machine light. With the canopy installed and ready to fly the front skids lift 1/2" before the rear. Maybe this particular kit has a very light canopy. Maybe some of the tail components are heavier than on other Whiplash kits. All I know for sure is the kit I have in front of me is tail heavy and the only way to correct it is to add extra weight.

I dont blame them. I personally like to run a bec as well. How much weight are you having to add to balance it?

On the other 2 Whiplashes everything is moved to the front, the batteries can not be moved any further, both are tail heavy, there is nothing else to move but to add more weight to the heli, one of the helis don't have receiver pack and bec which I have Never run myself, the other just has a bec and it is still tail heavy.

Can someone post a picture or two of how the battery cannot be moved forward. I tried MA site but it is not clear how the battery mounts and what prevents it moving forward. I saw the explanation but a picture would clarify.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I will get mine tomorrow, and I'm never afraid from using Mr. Dremel on a new heli if needed, so if I can find a easy fix, I will post it.

I am out of town this week for work so I can't provide a pic, but the battery is mounted to the underside of the tray. The throttle servo is in the same plane as the battery. So, if you want to move the battery forward the servo will be in the way. I took a foam pad (approximately 1/2" thick) and put it between the battery and the tray. This allowed the battery to clear the bottom of the servo and mount further to the front. The problem with this is the straps do not match the battery locations and only one will be around the battery. It would be easy enough to dremel new slots for the straps, I just haven't brought myself to this point yet.

I strapped two tp2100 rx packs to the front and it was still tail heavy. So, I guess a lot.

You might be able to flip the bottom frame plate and mount the batteries on top of that, but then you are drastically lowering the vertical cg which is awesome on this heli.
