I have also converted my MR03VE to MRX. I have to say it is a much better driving experience than my previously already modified 03VE. It took me around 45 mins on the conversion. I got so carried away on the conversion and test drives that I forgot to take photos during the conversion. Anyway, here are some photos of my MRX.
Side View - Lithum Batteries removed. Copper weight (not included in the kit) added at the middle bottom. The copper weight increase CG of the car and minimize traction rolling as Lithium Batteries on 12000kv is way too poweful together with foam tyres.
Back View - The car body clips are especially tight, which is good to prevent body from coming out. No need to use tapes anymore during race. I've tested with several bodies and they are all tightly fit. A great plus for the design.
Motor Mount View - Atomic 12000kv is used. But it's way too powerful on Lithium Batteries. I have to lower High Point to 20 (from 70 when NiMH batteries are used). I believe lower kv motor will be better. I will try that soon and share the info.
Bottom View - Carbon Fibre Chassis. Very light weight and rigid. Basically, the only components used from the original 03VE are the circuit board, servo gear set and servo motor.
Initial test drives are beyond my expectation. Generally speaking, it's very easily 0.5s faster per lap in a standard 9sec lap for a mid-level racer like myself.
This conversion kit is STRONGLY recommended for serious racers.
Tested with Kyosho Stock brushless motor and 9000kv motor. The 9000kv so far provides the best driving experience. I believe it will be even better with smaller kv motors. It will be great if there can be smaller kv motors on the market. In the meantime, I'll keep the 9000kv motor in the car.
The only complaint I have on the car so far is that there is no On-Off switch and I have to unplug the battery cable. It will be great if a power switch can be added soon.
Yes. Before using Lithium Batteries, I have been using NiZn batteries on my 03VE. NiZn has up to 1.9V each. I think the board can actually handle even higher voltage.
