mohanjude · **My 5B V2 Conversion -** 06.15.2010, 04:08 AM

OK guys I got Mike's conversion last night when I got back from work.

Took me about 2 hours to almost finish the conversion. All I got to do to run the truck is to attach Speed Controller (Shulze 40.160) to the Lehner 3060 7 turn motor.

The Polyquest 5S 6000ma packs sit 'perfectly' in side the battery tray and should be good to run the setup (10S 6000ma)

Got a 23 tooth pinion coupled to the Lehner. The Lehner sits perfectly on the motor mount. The wires will need to sold from the side as there is not much clearance from the 'bullet' female connectors on the motor.

This is another 1st Class Conversion Mike has done. Everything went really smooth - all the holes aligned perfectly.I had to shave off a bit of plastic behind the spur where the bearing is held onto the brake assembly. I also took of the brace behind the fuel tank as it fouled the batteries. I had to install some washers to take the gap of the brace.

Here are some pics

I just added your setup to the top speed calculator and it seems like you are heading for a somewhat agressive top speed. Is this correct or did I miss something. A 7 turn 3060 is 1000kv right?

Yes you are right - it was like a crazed animal. I took the pinion down to 20 and it handles better and the Schulze is less warm. It wasnt boiling hot but it was getting warm. I can only get the throttle to about 30% before the Baja starts to spin around due to the speed. I am going to take it off the tarmac and try it on a reasonably muddy surface to see if it helps with control. Not a big fan of grass but if I cannot control the car at high speed on tarmac it will have to go on grass.

I had to 2 spare Lehner Brushless 3060 Motors (7 turns) with me. Therefore I wasnt going to buy another Castle 2215. I may reduce the pinion down to about 18 - at present I cannot find my box with the Mod 1.5 pinions... so I am going to try this gear ratio for now with a 20 tooth.

I will try and get a video of the Baja later.

Sounds like fun Mohan! You should definitely get some video! Those big Lehners are definitely powerful!

Btw: if you have a spare Lehner sitting around, I can find a use for it...

OK guys here is the Video - very short but it shows what the Baja is capable about and how bad my driving is....

I installed a Garmin GPS - as you can see it was reset to 0mph and got to 60 mph in a short burst. I am certain that I did not go past 1/2 throttle max due to my morbid fear of crashing onto the raised pavement slabs.

I will take it out to a more open space and hopefully open it up.
