Compass-USA Sponsored Warp 360 Build Thread

Okay, guys... I think this is the next to last installment! We start setup, now!



During setup, using the RCLogger2, it's important the helicopter stays in one place and keeps the same attitude, so I decided to use the battery to keep the nose down. So, I had to install the battery.

I first put one side of the velcro on the battery... the fluffly stuff.



Then I put the hard, not fluffly stuff on the underside of the battery tray.



Next, I threaded the supplied battery straps through the frame.



I cut them to size...



Then attached the battery. Remembering that I never installed the tail blades, I did so .... next...



Bag 12 13 contains the tail blades, special washers, bolts, "Chinese weights" and nylock nuts.



I arranged the parts here as they will be installed.



First, I slid in the special washer--it conforms with the inside of the grip, then put a screw with a weight on it through the grip and into the special washer.



Next, I slid in a blade, then repeated the steps above for the second special washer.



Note that a weight goes on each side of the grip. (Weights appear to be washers.)



Then I repeated the process on the other grip. The blades are in.



Next I setup the length of the tail pitch rod. The tail pitch rod must be adjusted so the pitch arm is at 90 degrees with the frame. Note that I removed the washer that effectively clamps the link in the place. I did this so I could adjust the length of the rod by either turning the tail control rod to adjust the link on the servo arm or simply turned the link on this end of the rod. All this was performed while in step E of AR7200BX setup.



Here you see the pitch arm at 90 degrees--perpendicular to the boom. Note the sleeve has been pushed over the link.



Next I reinstalled the washer and used thread locker on the screw.



To start swash plate leveling I first adjusted the aileron and pitch links to 45mm from end to end.



I installed the links and found they needed to be re-sized. I re-sized the links and reinstalled them on the swash and servos.



Above shows the RCLogger 2 unit and the adapter for leveling the swash plate.



When you install the adapter to the swash, you must make sure it is installed, then clamped to the swash plate itself. The adapter must be adjusted so it is parallel with the frames or else you will get readings that are a mix of pitch and roll axis. Not good!



I turned on the RCLogger 2 unit, zeroed it on the motor (this why I needed the battery) and snapped it on the adapter. I went to step G in the AR7200BX and these were the initial values read.



It takes some playing around to get used to how it works. I found the adapter/unit combination would move slightly the more you played around. I clamped it down really hard and started over. It never moved and made it much easier to get the swash level. If you do clamp yours hard, be aware the top section of the adapter does bend. Check the lower side for flex as well. If yours flexes, it will compromise your readings as the sensor will be tilted! Additionally, you may break the top adapter! You still have to learn what does what and it does take patience to get right. There are interactions of the axis but once you figure it out. You can get it perfect.

I suspect this would be easier to use on a larger helicopter as the servos have more resolution so you can lock in a value easier. This was after about a half hour of playing and learning how to use it.

As you can see above, the AR7200BX is in step G with the elevator servo selected. It shows the swash plate is perfectly leveled. We'll check this in a couple of days with the tool Diviner is making.

My take is as I stated before--this should be easier to use on a larger helicopter. If you get one and use it on the Warp, just take your time and you'll get it.

Next up, we'll compare this result with the tool Diviner is making. I suspect it will be spot on, but it's nice to have a way to confirm--at least for the first leveling. Then we'll complete setup.

The details in this well recorded photo build are exceptional... thanks for taking the time to setup and post...

Scott,

Are the washers meant to be like Chinese weights? I thought those were built in to the grips.

You're welcome! Thanks for the complement!

My copy of the manual says the washers are Chinese weights.

thanks for spending all that time making this thread ,as i did follow it through out my build ,nice clean wirring job

[dunkonu23]

You're welcome. I'm glad it helped you some. I owe thanks to those who caught mistakes I made and pointed them out. It's much better to know you made a mistake and correct it than it is to perpetuate it.

I still haven't flown mine, yet. I still have to complete setup. So, please take it easy with the way the wires are running near the ESC.

Scott

[vincent_tx]

What did you use to attach your ESC to the frame?

[dunkonu23]

I used Scotch 4011 tape. I took a suggestion from BarnStormer who used a piece of plastic as a spacer on the underside of the electronics tray so tape would work. My spacer if you look at pictures closely a page or two back, is two 2mm thick carbon fiber pieces CA'd together -- I had that laying around. The tape is applied to the ends of the ESC to allow the FET's to cool properly and is stuck to the ends of the spacer. The programming button is accessed through the cutout in the frame.

I hope this helps!

I'm hoping Diviner's leveler gets here tomorrow so we can check the leveling done with the RCLogger2. After that, we'll finish up setup. So... no more tonight, folks.

has anyone else had a problem with the tail pitch slider i cant get the brass bushing tight without the bearings geting all notchy anyone got any ideas to what i could do

[Jeff_Barrett]

I just got your PM and was going to respond to it ... don't crank the slider down, just get it snug and let the thread locker do it's job. If you crank stuff down too tight, it either breaks, binds, or distorts.

[dunkonu23]

No Diviner tool today, so I'm going to check level with a pair calipers. I'll report back. I'm sorry this is taking so long. I want to show different ways of leveling the swash so hopefully this will pay off.

Scott

[dunkonu23]

I checked level with my calipers. It's difficult to do because there is no real way of knowing you're checking in the same place on all three arms and it's impossible to get a good measurement on the bottom of the swash plate, but it looks good. I still want to wait for the "Team Flux Capacitor" leveler before I continue. My apologies. I'm really anxious to get this helicopter in the air before the snow storm Friday!

No worries, take your time and do it right. I really appreciate the time and energy you put into this. I rather follow a meticulous build in a slower pace than a quick build. I have one of those right here next to me so no need to follow another one of those

[dunkonu23]

Thanks, Kendo! I appreciate folks who like things done right! I will say I programmed my Koby tonight. Easy as all get out! Here's a link to Rob43's Koby programming guide:

It couldn't have been easier! Throttle curves are:

25 flat
50 flat
75 flat

to start!

Scott

[Kendo]

Is there any other way?

Related to that, or maybe not, either way here's a picture to keep this thread interesting while you wait for the swash leveler. Any guesses to what that grey piece of plastic is?

[dunkonu23]

No clue.... if I had to guess... an ESC mount?

Scott

[Luigi_tuga]

An anti belt-skip device, last generation?

Snow makes for soft crashes! Does for me when skiing!!
