Darth's "Heavy B" Blackhawk


Ok, Ive decided to do a blackhawk build and show some pics. The fuselage assembly is prety much straight forward by gluing halves together and or channeling the main body together which is what I Did. I would say the hard part (to me) is making the Chassis platform, which isnt to bad. I tink attaching the landing gear may be a little harder than most. Keep in mind this is making it up as I go. When its all said and done, I do plan on using the King2 frame. Also plan on using the 325mm blades. pretty much the same setup on my 1:18 Apache.
AH-64 Apache.
INFO: It is the Apache body for the T-rex
Chassis: King2
Rotor blades: 325
Gyro: Stock ESKY (Non heading hold)
Tailrotor: AXE CP motor and tail blade
Battery: 2200 12C 3S 11.1V
Main motor: ESKY Brushless
Servos: Stock King2 8Gs
Reciever: Stock King2
ESC Main motor: BL Dynam 30 Amp
Tail motor ESC: Brushed GWS ICS 300E

To get that strut look on the landing gear, you can wrap masking tape around the music wire. Another Idea is using different size fuel tubing.

Did some more work on the main landing gear
Made a couple of braced "L" brackets and used a 1/8" landing gear strap to hold the gear on the bracket. Once the desired height is obtailed. I will glue in some stops above the main gear wire on the "L" bracket. Bracket was CA glued to the bottom chassis plate.

Love your helis. Can't wait to see the Blackhawk finished. If I can ever quit crashing so often I would like to build a heli using one of your bodies. :-)

Looks great, Darth! A couple of questions: Is there any particular reason you're using a King instead of a Trex or Belt CP? Can you post plans for the chassis and landing gear?

No real particular reason for using the King2, the T-rex, MX 400,450, Belt Cp, Revo, all will work. I like the king2 and I find it easy to work with, actually more economical. The king2 is a lighter frame and because Im using a motored tail driven tail rotor, I will not be using the tailboom. If you go the same route I go in this build, you will loose the tail boom also on any of the other frames too. Im gonna try to make chassis platform specs available.

Front strut covers:
I made these out of scrap plastic. Pretty easy to make.
The front of the strut swings out to allow for the removal of the nose section and it swings back in place after installation.
I may try to eventually mold the covers if I can do so without them webbing on me.

Tailwheel completed
I made the tailwheel strut from Plywood and I kinda rounded the edges. I also installed a lite ply plate in the tailboom and the landing gear plate is screwed to it.
Im soon to be ready to install the tailmotor and the Chassis and the soon a test flight or two before I paint fuselage

Tail motor installed. I even added the offset angle to it. I also removed the King2 chassis from the Apache and installed it into the blackhawk. Its extremely windy outside right now so I did a test hover in my living room. So far all is A-ok. Seeing I only have about a 5 x 5 feet space to hover. I managed to pick the heli up about 2 feet. It handle real well. I cant wait now until the winds outside die down. As a note, i noticed that its not going to be a problem taxiing this on the ground.

Quasied semi scale quad tailrotor (Dont laugh, it works) Still to windy and real cold. Did more living room hovering today
One thing I have noticed about using the electric tail motor, is that I can adjust the pit to allow for a slower rotor and more pitch without affecting tailrotor control. Suppose to be getting into the 60s weather wise in a couple days. I may have to try some running landings. Today it was 30 degrees

Running landings. That would be cool! You are just trying to convince me to build one of these aren't you! :-)

Took Blackhawk out for a flight today. wasnt able to get any pics and it was getting dark. Slight breeze but it flew better than a Pod and Boom heli. It flies very scale like On a slow lift off to a hover, the front wheels come off the ground before the tailwheel. Looks very realistic. As the heli goes into fwd flight, the heli levels off nicely just like the real hawk. I did one running landing on blacktop road. Touch down was nearly a three point touchdown with the tailwheel contacting a split second before the main gear. Its something to experience because of the rolling motion. The four blade tailrotor performed great. I had no wild swinging at all. I really didnt time the flight because I wasnt flying on a full battery. I did some test hovering with it a day or so ago in my living room. Hopefully I'll get some inflight pics soon.
