just an update. i am waiting on carbon fiber sheets from dagraphite.com before fabrication begins. also, i am awaiting my ESC.

I decided to install the Plettenberg Bolido in my FG touring car and build a car for speed. Alas it was quick but too quick. It kept wheel spinning even with the most gentle throttle curve. To keep the mechanical brakes I decided to use a converted Futaba 9CS transmitter with the gimbals that centred on the spring on the throttle side. I then used a mix to apply brakes when the throttle was 1/3rd in reverse position and let the brakes off at 1/2 stick reverse position. The schulze controller only applies when the stick is in reverse in 1/2 position and after a delay of about 1 second. SO basically I have Mechanical hydraulic brakes and elektromotor brakes which can be weakened by using a the boat setting on the schulze.

The lipos are Thunderpower extreme V2 - 5000MA and running 2 sets to have a combined voltage of 44.4v. The total rpm should be over 35000 rpm on the bolido but I have restricted it on the throttle curve to stop the destruction of the motor.

The motor mount is a custom job and took less than 2 hours to mount onto the vehicle. I did not make the mount but have now sourced a chap in germany who can make them.

I had to change the wheels to stadium wheels as I kept burning the road wheels - I burnt a set within 1 hour. The stadium wheels looks a bit silly but I need to think of an innovative way of mounting a shell - perhaps a MT shell?

I am now waiting for the next conversion which is to mount a Lehner 3080 Monster motor onto a MCD 4 WD truck and power it on 18S.

hi

@mohanjude
nice ride! now add a little watercooling circuit with a radiator and pump in there!
18s in a MCD sounds good.

@ryu james
i usually buy my FG stuff directly here in switzerland. in germany there is a big shop that also sells internationally. rc-car-online.de
the electric motormount for the FG can be bought here http://www.onefive.de/e-power/epower_fg_umbau_I.htm

bye

I have not had a chance to do the video yet - I was trying to struggle with burning tyres. Once the weather improves and it is a bit brighter and drier I will take video of a good run with some spped meassurements using the eagle tree GPS or the speed gun

OK I made a couple of videos. It was a wet day and I could not push the throttle more than 20% of the range. However I did manage to get some videos posted.

Any tips are welcome on how I can improve traction.





This is the car running on a paved road at and speed gun showing 39mph. If I tried to go any faster the car would spin out of control.

This video shows how the car was difficult to control in a wet lane with lots of leaves to make things worse
