Адам Дрейк про летне-зимнюю практику ДВС & электро

Собснно само письмо (прочитал его советы в одном из номеров):

Dear Adam!
Thank you for your article "top 12 tips" in RC Car Action.
Would you like to answer to my question?
My son takes a good practice in RC within 2 years. He is 13 years old and schoolboy and I am a mechanic with him.
So, my question is about practice within winter.
If you know in Russia we have (unfortunately) very cold winter. And we  can not use nitro in our outdoor track, and we have not yet indoor track  for nitro too.
What do you think about 1/10 electro in winter and main 1/8 nitro in summer? 
First of all: What kind of electro we need to use?
I think about 2WD, or 4WD(main I think), short-course, of tyring 1/10.
What kind of practice is best for our winter (indoor practice)? What kind of practice best for ability and skill and accuracy?
Thank you!

А вот и ответ (сам не ожидал, честно говоря)....

Hello,
Racing 2wd or 4wd electric in the winter will help improve your skills.   2wd is very difficult to drive and will make you very smooth.
