So I have been very busy and thus absent from the discussions around this car and the powertrain choices for them.
I have an idea and it may not be a good one but its an idea.
To me the appeal of Lemans racing prototypes is the variety of chassis and power trains that are competing.
My idea is that in the spirit of LeMans you allow multiple powertrain configurations.
I would allow 25.5, 21.5 2S blinky. OR 17.5, 13.5 1S blinky.
I realize there are major speed differences between them, and in the end this might cause for a huge mess. However I think if you change up the racing format and have a UF1 style qualifying system you could run a 15 or 20 minute main, or run a certain number of laps for the main, this would dictate running a pace instead of an all out sprint. Also the track will have a limitation based on grip and layout. Its just an idea, might make for some very interesting racing.
I still have a good stock of cars, spares, and bodies. I am low on some of the hop ups , but I will be getting more.
