Modify Hotshot re release stage 1

This is the first stage of Hotshot re release upgrade since I built it few years ago. 

Objective is to improve the steering especially its ability to return to neutral point after steering action.

Servo has been upgraded to DSPower servo - more powerful than the original servo used on the kit since I built it. In addition, the water proof compartment has also be replaced by alloy chassis to enable steering rack between the servo and the L and R steering rods.

Servo saver was removed too.

Stage 1 modification completed. Also changed radio to FlySky with FGr4D receiver. ESC and motor remained unchanged - silver can and Novak GTX7.

KittyHawk 1/48 F-35A #7

Been a while since last update on this project.

Mixed Gaia 1001 silver with C317 for the base color. Wanted to make a metallic grey.

Yokomo YZ-834B re release #3 (completed)

Completed the build and bodyshell.

Test run over weekend too. 

It is slow (blame the 27T motor) but fun !

Mugen MTC2 #2

Installed bumper and body posted, receiver, motor and cooling fan

The steering swing rack is solid. Now pending the four arms and legs.

Mugen MTC2 #1

One weekend of work :

Very solid arms and I have changed the original graphite chassis to WeiGo 1.5mm alloy chassis

Fit with a PowerHD S15-M servo and HobbyWing G4R 13.5T torque type motor.

The plan is to run in blinky mode.

First primer on F350 front body

The body has sign of vintage already - white turns yellowish and black dots ... sanded surface and washed.

Spray with 0.5mm Iwata, Gaia black/white mixture of surface primer on both inside and outside surface. 

PR Racing V4TR #5 (completed)

 Final step as always - bodyshell

Yokomo YZ-834B re release #2

 After loading electronics, identified that rear spring cannot support the weight. Found a purple spring from Mugen MTX gas car which can be a good replacement. Front spring is original from the box. Front shock is filled with 400wt and 300wt for the rear.

Clean and mask the bodyshell for base white color and shading

Tamiya F350 test run in basement carpark

This time running with front bodyshell mounted.

No issue on gear shifting and the connecting rod works well.

However, found that the steering servo mounting screws are loosen after some run time.

Yokomo YZ-834B re release #1

One of the most memorable 4WD buggy racing machine in the RC history. 

The chassis is pre-built, only need to install electroincs. The chassis seems to be wide, but actually space for electronics is limited. Picked up those with small footprint, eg LRP Quantum 2, KO receiver, low profile servo. 

Wiring done, and test fitting the bodyshell. Fitting bodyshell is a challenge indeed - the rear mono shock has a few connecting rods which will block the bodyshell to move backward, while the metal bar on top will also limit how much head room the bodyshell can have. 

What am I running over weekends ?

1. Pan car : Fantom EP-4WD re relase

2. Awesomatix A800 MMXA

3. Cougar

MFH 1/9 HRD Vincent Black Shadow

My first MFH bike

A pair of modern 1/12 pan cars

Awesomatix A12X and CRC MetriCKs

Xray X4 2022 - ESC cooling fan

X4 is equipped with 4.5T motor, and in last few rounds the ESC was 150c after run ... 

Factory also suggests to use a ESC cooling fan on such situation. Hence moving the ESC a bit towards motor and fit in a small cooling fan facing the bottom "fin" of the ESC.

Schumacher FT9 FWD #4 (Completed)

 

Tamiya F350 chassis completed and first outdoor test

Paired it with a FlySky i6 radio which was meant for airplane, I like its simple design and user interface - plus one of the button on top has 3-stage which is perfect for 3-gear shifting.

Bodyshell has yet to be done, tested run with a LRP 5200HV pack for like 10-15 mins around my home. 

The chassis has been built like 15 years ago, if not more. After the run, there are few areas to fix :

1. gear shift servo link is loosen

2. Front right leaf spring connector gone

3. Steering servo is locked at its full turn position

Tamiya 1/6 Fat Boy Lo

This is not a limited edition and only released about a decade ago, but it is so hard to find a NIB.

This kit has been stall for over a year. Cannot recall the reason what made me to park it since then ...

Anyway, spent two days on it, one for completing the build, and one for first paint job.

Result : 

And completed the build

And after first spray job
