E Gemini Hovercraft Progress

I have started working on my E Gemini hovercraft.

Deciding where things should go
Deciding where things should go

Most of the plastic pieces have been trimmed and the electronics tray has been mounted into the hull with silicon.

I have soldered the my connectors for the esc and battery pack replacing the Tamiya connector on the battery with a deans one.

I chose to use a specktrum receiver in the hovercraft as it means I can use the same transmitter as I use on my cars. I have tested the electronics and everything is working perfectly.

Next I need to trim down the lower hull and start working on the rear of the craft.

Red Bull 7 Progress (up to Issue 44)

I have caught up with my RB7 subscription and built everything up to issue 44.

I decided to put aside recent issues until I had enough to finish and cover the differential instead of having to leave half finished bits on the side.

In this session I built and fitted the rear differential, differential housing and the rear suspension arms.

Tamiya Volkswagon Camper Monster Truck

I picked up this kit last week in the modelzone sale but only just received the additional parts needed to complete the model.

It was about half the going price online and eBay.

The box shows it painted white and red but I decided to go for white and orange instead.

The free bonus parts included are ball race bearings. Its pretty handy seeing as the first thing I usually do is replace Tamiya’s crappy plastic/bronze bushings with bearings.

Aside from the paint, I also needed to order a servo for the steering and a radio receiver. As usual I went for a Spektrum receiver in the hope of unifying all my radio gear under one compatible type.

E Gemini Hovercraft Kit Unboxing

My biggest undertaking so far.

This is a model hovercraft kit I have just received.

It looks to be both a unique and challenging build.

Twin Hammers new body and accessories

IMG_5446

I wanted to make my Twin Hammers more unique so I started by replacing the standard plastic body with a set of aluminium body panels.

WP_000519

I decided to paint the panels in a basic desert camo scheme of sand and earth.

WP_000521

Some decals were applied to the side panels to add a bit of detail.

I also replaced the vehicle race number plates on the back of the vehicle with recovery boards. These are also aluminium and were painted desert yellow.

To complete the new look I ordered a pack of rock crawler accessories from eBay and strapped some gear to the roof and recovery boards with bungee chords .

Red Bull 7 Build

The Red Bull 7 is finally starting to look like a car.

The steering is complete and servo attached. I also have the front suspension and rear wing made but not attached.

Low Voltage protection for Models Without it on their ESC’S

For the first time recently I ended up with an Electronic Speed Controller that did not have built in Low Voltage Protection but did support LIPO batteries. You should never let a LIPO battery drop below 3V (You should get rid of it if it does.)

WP_000423

As the esc did not have LVP and independent solution was needed. After a little research I found these usually come as a little circuit board with an led screen that connects to the balance charger on a LIPO battery.

A LIPO battery generally has two connectors. One to connect to your model and one to charge the battery and balance the battery cells. The charge connector is not needed when the battery is in your model so you can leave a low voltage protection unit attached to it.

WP_000416

I managed to buy some units off ebay that work perfectly and only cost a few pounds each.

WP_000422

The units are simple enough. You give them a voltage you want them to warn you at and they will buzz when they drop down to it. They work well and I have never had any trouble hearing the buzzer.

Here is a video of them in action. The display even cycles through the voltage of each cell

Twin Hammers Crash And Repair

My Twin Hammers had a head on crash with a monster truck. This shattered the monster truck chassis (my blackfoot) and snapped a metal tie rod on my Twin Hammers. I am not too fussed about the Blackfoot which still runs but its gearbox kinda just floats between the wheels. The Twin Hammers however being my flagship electric car I wanted up and running ASAP.

WP_000406

This was a nice test for me to see how easy it is to back order Vaterra parts. As a brand new company they have already shown they can make good cars but I had no idea how good their parts support would be.

I ordered a set of tie rods and rod ends from modelsport and had them in under a week. I needed the rod ends because the rod had actually snapped inside one of the current ones making it impossible to remove.

WP_000447

The repair was easy. All I had to do was remove the body, cut out the old tie rod ends and snap the new ones into place.

Team C Racing Jekyll build

When I first saw this kit on modelsport I was intrigued. It was only £39 and I wanted to know just how good a car you would get for the price. You have to supply your own Electronic Speed Controller, Servo, Receiver and Motor bringing the total minimum build price to around £70- £80. I spent a bit more as I wanted to but some more decent bits in it.

WP_000358

The packaging and parts were a decent quality considering the price and the manual was easy to follow. This would make a nice inexpensive first kit.

WP_000372

Things I used to complete the build:

  • hitec servo £6
  • 10 turn limit mtroniks sniper esc around £25
  • 13×3 Orion Motor £18
  • Spektrum 301 DSM coated reciever £23

WP_000376

It seems I made a bad choice with the esc as the 13×3 motor seems to overheat it very easily, I am looking into a solution for that. On top of this I melted a battery connector to the esc so I ordered some traxxas connectors to deal with the current.

WP_000386Soldering the new connectors

WP_000384

I also ordered a set of UK buggy bearings to ball race the kit. These replaced the bronze bushings that come as standard.

WP_000388

I do intend to replace my battery connectors with deans but the reason I went with a traxxas in this instance is I got this rocket pack battery in a sale. Its a 5100Mah 8.4 V Orion Rocket pack and really makes the thing go.

The bad thing is its too big for the battery compartment so I have to tape it in each time!

In summary this kit is easy to build, robust and well its cheap enough to buy a second one for a complete set of spare parts. I will upload some videos of it in action soon!
