After a considerable amount of help from lots of people on this forum, I've recently purchased a Associated Rival mt10 and a WLTOYS 144001 for my 5 year old lad.
I charged the 144001 last night for the first time, then nearly wiped it out on our sofa. Its rapid early days but am impressed.
Haven't charged the lipos for the Rival mt10, looking forward to a new hobby especially if it gets our boy outdoors.
Without this Forum I wouldn't consider buying a Rc car but with everyone's help and input am confident it'll be fine.
