1/5 scale brushless monster conversion. tips welcomed.

[tc3_racer_001]

imo in regular setups, gears = something more to break lol. kiss :)

hi

i would also target around 25'000 rpm. a good tuned zenoah does bout that.
those cars are geared very high so you need a high torque motor. the 30er lehners seem to be about right or the plettenberg bolido. there also the pinions fit directly on the 10mm shaft.
a schulze 40.160 should do the job. if the promised XXL schulze 40.300 come out soon (?) those would be even nicer. i havn't converted one of my FGs yet but personally i would also do some kind of small watercooling circuit as there is some much room in those cars.

hey rhylsadar,
where do you get parts and stuff for your 1/5 FGs? i havent been able to find any good site for 1/5 scale hop up parts.

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.

That build is huge!

Well done.

Have you got any video yet??????

[rhylsadar]

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

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

I thought the same thing when I was looking at it today. But those side trays are removable, and kinda flimsy. That area is going to take some beefing up.
Its one heavy monster....

I also saw a few conversions with Lehner 2250 or 2280 motors. If you compare those motors wheightwise with Neu Motors you should have a good match for your car. An MGM 12545-3 ESC should also do the trick. Good luck with your project.

Did anyone watch the 1/5 MT vids from him? Impressive, I'd like to see the eagletree graphs off that. Here is his vid list, part 6 of the MT buildup really shows what brushless is really about. Hard to believe that truck is 20+ pounds

I've been enjoying those videos. I have never seen the gas version that fast and I never seen the gas version do wheelies like his does.

[BL_RV0]

Yeah, that Bolido throws it around like... like a.... well.... something smaller.

[Takedown]

By the looks of it its not an FG at all. They have many copies of the original base models of FG like their MT's and onroads from the original batch that smartech now still produces. Its exactly the same as your model.
