Hi
Newbie Member here.
I purchased a winner sport RTR from ebay only £155.00 this includes £2.00 Paypal surcharge and £14.00 postage.
Great car for the money, I didn't have any 16% fuel only 10% for my Helli. the engine started after about five tugs on the pull start no trimming to do even on the steering. goes like a bat out of hell so far I have run only two tanks of fuel trough it but very fast much better than the Kyosho RS200 and Sand Master I have owed previously.
The only down side I have found is when driving on my gravel dive spinning round a corner the gravel tended to get stuck in the wheel rim it still drove just with three wheels instead of four.
As for spares backup see
www.smartechracing.co.uk they have them all listed and far prices I would say when comparing to my other electric cars and Helli
for the money it's a cheap intro to nitro cars I think you can't go wrong
oh the needle setting on mine was 2 1/2 turns from fully closed
PS As far as i can make out CEN is now part of or owned by the same Toy company.
