CRT .5 questions

[crazyjr]

I am ready to convert my CRT.5 to electric, I need some info.

My plan is to use the chassis conversion by Mike (RC-Monster) with a lehner basic xl 1200/quark 80 car esc and 5s 2500 mah flightpower 25c pack. I may also do the arm conversion when available, to convert to a 1/10 truggy. My questions are about the weight of the conversions. How much do they weigh? I know my nitro .5 is 3 ounces heavier than my 1/10 ST (T4). I know my battery weighs 370 grams, and the chassis will add weight. I'm just wondering how the added weight will affect performance? I plan to run a lehner basic 1200xl w/5mm shaft conversion at first, but might need to go to a neu motor if this is too much for the lehner.

thanks for any info given
