In this post I start to build the engine for my Kyosho Red Bull 7 Formula One car.
The first part of the engine to add to the crankcase is the crankshaft. This is first given a thin layer of after run oil and then slid into the crankcase.
I used HPI after run oil which I already had from maintaining my other models. Continue reading Red Bull 7 Engine Progress
The crankcase is the first part of the GX21 Nitro engine which will power my Red Bull 7 model. The GX21 is a 2 stroke engine capable of producing about 1.8bhp.
The crankcase currently contains the carburetor attaching screw and two ball bearings.
With the next batch of parts I get the crankshaft piston, cylinder head and rear engine plate.
I finally got started on my 1:8 Kyosho Hummer H1 Subscription.
At the moment I have ignored that actual components of the car itself and worked on the body.
Making the side frames
Pegs are useful for holding the part in place whilst the plastic cement sets.
The frame is now ready for the panels to be attached.
Panels attached and ready for painting.
I started by spraying some mist coats
I decided to paint the Hummer the classic yellow they are often seen in.
Side view
I have fitted the rear wheel hubs and dog bones to the car.
The rear wing has also been fitted although this is the display wing. A separate (more durable?) wing is provided for driving around with.
I just got round to bringing my Hyper 7 back into action. The pull starter stopped working a couple of months back so I have fitted a new one.
I checked the condition of the old start when I removed it as sometimes you can repair them but in this case it had snapped.
Usually pull starters can be a bit of a pain to replace because it either means removing a lot of parts to get to it or removing the engine itself. I managed to cheat a bit and just remove the rear diff and wheels.
I had a bit of trouble testing my car after as it didn’t want to start in the cold but the hair dryer trick solved the problem.
I recorded a short video while driving with one hand of the buggy back in action.
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.
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.
The second 4 parts of the series include the main chassis, the front chassis, the front lower wish bones and the first Tyre.
Strangely they have also sent Vettel’s head which I can only assume they have included as an option if you do not like Mark Webber. As far as I know British and Australian subscribers get a Mark Webber edition where as Germany are further into a Vettel themed model.
You can see the First wheel and tyre glued together in the Photo along with a battery to give an idea of scale.
My first batch of parts for the Red Bull 7 kit arrived today.
The parts include bits of the front wing, rear wing, a wheel and an oil filled shock to build.
The front wing had some small parts that were pretty annoying to fit but I got there in the end.
You can see the oil filled shock balanced between paint pots in the photo.
This is to let the oil spread around the shock assembly and remove pockets of air.
The LED’s shown in the video would not light up using the led controller I installed so I had to run them off of a 9V battery instead.
