Here are the instructions to build your new BWD TR1 Tri-copter kit. If you see anything that needs more detail, please let us know through our contact us page.
Thank you for choosing the TR1 as your next Multi-Rotor experience!
Before we get started, here’s a few items you will need in addition to a 4 (or more) channel 2 stick aircraft radio:
The easiest bet is to snag a TR1 accessory combo package from here http://stores.intuitwebsites.com/CMoon/-strse-46/Billet-Works-TR1-Tricopter/Detail.bok and the 2200 mah 3s lipo’s of your choosing.
3x 2208 Motors
3x 25 amp esc’s
1x Multi Rotor Control Board
1x Power Distribution Board
4x 3cm Male to Male Servo Leads
3.5mm Bullet Connectors (3 Pairs)
1x Orange RX 6 Channel Receiver (If using a Spektrum radio)
1x 8x4.5 Propeller Set (Green)
1x 8x4.5 Propeller Set (Black)
1x Hitec HS-82MG Servo
2 pairs Nylon T-Style Connectors (Deans
2x Velcro electronics straps – for your battery
2200 MAH 3s Lipo
Axial/Traxxas 4-way or similar
2.0mm hex driver
And of course a nice building area like the Jumbo Screw Catcher from Cow RC
To begin, you will need the main frame, front arms, and rear frame, along with 8x 3x10mm button head screws and 8x 3mm lock nuts.
Using the front 3 holes per side, connect the arms under the main frame using the hardware you set aside. Now using the 2nd and 4th holes on the rear frame, attach it under the main frame at the rear. A loose fit is preferable until we get the rest of the parts attached.
Now we need 6x- 3x14mm button head screws, the frame as it stands, and the skids. The skids have a step on front and back to accept the front arms and rear frame, while still fitting firmly against the main frame. The main frame should be the top part of the assembly when sitting on the skids now.
Ok, time to install the control board. You will need 4x- 3x16 button head screws, 4x 1/8” alum spacers, and 4x lock nuts.
You will run the bolt through the control board, through the spacers, through the frame, through the power distribution board, and then install the lock nuts. Snug is plenty here, the power dist board as foam on it which will keep tension without you getting aggressive when tightening the bolts.
Next you are going to need the canopy and 4x- 3x14mm button head screws. You will run the bolts up from under the frame and into the 4 holes down the centerline of the frame, and into the canopy.
Now it’s time for the tail pivot. We start by pressing the Fast Eddy 5x11mm bearings into the bearing blocks.
Now we build the pivot itself. You will need these parts.
Press the shaft through the bulkheads so that the 5mm section extends beyond the bulkhead…the 5mm portion is what rides inside the bearings.
Now you’ll need 4x- 3x8mm button head screws to attach the bearing blocks to the rear frame. This assembly will sit on top of the rear frame. The 4 screws will come up through the rear frame and into the bearing blocks. The exposed bearing face should sit towards the pivot bulkheads.
Next we install the motor mount onto the pivot bulkheads with 4 more 3x8mm button head screws.
It is easier to mount your motor to the motor mount prior to installing the motor mount to the pivot.
Now we install the servo posts. The rear frame is slotted to fit various servo sizes. I use the Hitec HS5085MG and HS82MG servos on my personal TR1 builds…but any similar servo should work fine. That said, the included servo posts are for one screw mounting and were designed around that servo platform.
Now go back and make sure all of your screws are snugged down. No need to get crazy, but you also don't want your TR1 vibrating itself to death on the first flight.
All you have left is to install your servo, receiver, esc’s, and battery. When installing the servo, I use a 1” servo arm and the supplied rod ends. I like to have full throw out of the rudder pivot. When plugging things into the board, remember that on most KK style boards, the wire nearest the edge of the board will be the negative wire! This should help with any of your board questions http://rcexplorer.se/Educational/kkguide/kkguide/tri.html
Balance your props before you try flying!
It makes a world of difference.
Now go enjoy your brand new and truly unique BWD TR1 Tri-Copter!!!
When you setup your board/esc's for the first time, please do so without the props mounted! If you have any questions, please don't hesitate to contact us! Also, there is a wealth of knowledge out there about multi rotors. www.rcgroups.com is a great resource, as are many other sites.
