Pull the trigger mate.

Is there a guide to modifying the tail with the above?

But I don't see a listing for the mixing arms, so it's possible
that it's the complete head.
Its the right part, I ordered one on my last order.

Yep, check out our buddy Deutche Mike's blog entry on the 9116 Direct Drive tail conversion.

The V912 swashplate uses 2 sets as well.

The main shaft is 4mm, same as the 9116.
Has anyone tried this swashplate on the 9116?
For that matter, how is the v912 swashplate? They look similar.

On both of them, it looks like the outer set of balls will clip the
anti-rotation guide. The shorter set still look farther apart than
the balls on the 9116 swashplate, and will have more cyclic action.
You might get by with chopping off the longer set.

I know at least one of you are running a V912 swash. but I don't
remember the results.
I have a V912 swashplate, but it does not fit. The shaft diameter is bigger so it would need to be packed out (sleeve over shaft) and the overall size of the swash is much bigger. You would need to provide a new swash guide that would have to be mounted further forward, but the motor is in the way. Also the swashball size is bigger. It would not be impossible to mod but I cant see any benefit in doing so other than the different swashball position (further from shaft)

I found some complications when moving heads from other heli's. The fixing screw for the head can be in a different position meaning that a mod to the original shaft if possible. The ZR Z101 has a much higher screw which meant I had to buy the ZR shaft. But I also had to drill a new hole for the top collar as the heights varied between the two heli's.

My 180A pro motor arrived today, so will have something to report on soon.

First flight done with good results overall. The 180A pro is almost a straight swap, I needed to slightly increase the main hole size where the bottom of the motor goes through the mounting plate and the pinion wheel needs to be prized slightly lower which was easy with 2 small screw drivers. Very breezy here today so I could only manage an indoor hover, the motor does not feel more powerful yet but it has not been tested fully or run in yet. The motor seemed very smooth and quiet, but perhaps I was used to the sound of the failing std motor.

The biggest change was the stability in hover, I have the syma tail motor which is getting old but still held up well with the small test so far (remember I am running the V912 PCB), but I was surprised how stable the hover was with my modified head. I put spacers under the flybar to restrict movement and the flybar weight has a total movement of about 50mm (2 inches). I also reduced the weights by about a third and my flybar is off a ZR Z101.

The real test will be in light wind conditions, hopefully a window of opportunity will open soon. Front cyclic looks to perhaps improved but the other 3 axises feel sluggish at present, I still think I have a problem with overall servo throw.

The V912 offset mixer which will take ages to get here might be another positive?

The 180A motor sounds promising, Laidback_racer.
Could you post a pic or 2 of the motor & it's "replaceable brushes" please?
Am interested to see exactly how they are set up & their size.
Need to see how they compare to the S 16D here, that's all. Ta muchly.

I hope that you read the posts regarding the stock charger, Nicke.
It's a piece of junk & not really up to correctly balancing any type of battery.
It will over-charge one cell, leave the other one at a lower voltage & reduce your flight times & the batteries life span.

You're much better off to buy a good balance charger.
I keep posting these 2 as highly recommended.

& another neat, cheap unit is the low voltage alarm.

The 180A pro took about 10 minutes to install. I cheated and drilled 2 holes in the floor tray under the motor mounting screws instead of dismantling the body. It will be interesting to see if this motor is a low maintenance replacement.

My camera struggling a bit to see the detail of the 180A brushes.

Thank you.
I've seen enough.
Still got really small X sectioned brushes, mounted on those crappy brass levers that they call springs.
They might be a little better than the stock but not by much.

& Not a patch on the S 16D set-up.

Where are my damn parts?

sigh.. stock li-ion and stock crud-charger..
my voltage meter shows up to .4v difference in cells at times.. im flying at least once a day on each of three batteries.. i think the cheap charger is taking its toll.

can someone please tell me for safety's sake what the max charge and ideal minimum charge is meant to be on these batts?

my flight time is slowly but surely shrinking everyday.
i have maybe 5-6 minutes of flight now..

ive read here more than a few times, guys saying they get 15-18 minutes from their li-po's.. anyone get this performance?
i know that flight times depend more on the heli's weight than its battery mah.. i have a reasonable stock weighted 9116. (ive not weighed it, but its only had horizontal stabiliser and dec-bars removed.. some of you have lost 20% weight by the sound of it

out of interest.. (for us all i think) can some of you please post your battery specs and average (timed) flight times?

Hi Gygax,
I thought you bought some Li_Po's & not the Li-Ion batteries?
<snip>...im flying at least once a day on each of three batteries...</snip>

I seem to remember that 850/900 mAh Li-Po's were the recommended way to go.
Yeah/Nay?

& I'd be a tad doubtful about anyone getting ~15 to 18 mins flight time.
Both motors would be a little on the warm side after that long, I should think.
Not to mention, the brush wear.

I'm still on the original Li-Ion but not flying ATM coz of the charger's irregularities, but I think I was getting about 6 mins before flame out.

They must've done a few mods to get that air time.
Be interesting to find out.

no lipos yet..

im saving for them and an iMax charger. just have to scrounge a powerpack for it then.. hopefully my old laptop one will work.. i have to find the old post here about what works and dosn't

yeah.. if you could in theory fly for more than ten minutes.. the motors would be scorching hot

just how much of a risk do you think these things are? my batts are permanently out of balance now, to varying degrees..

i charge them in a big ceramic garden pot that i can pick up and throw outside in a hurry if i have to
