Hi as a new member I am after a bit of advice, I bought my 8yr son a racing fighter for Xmas, I thought it would be to quick for him to handle so left completely standard, after only 2 runs he has totally mastered it and I am looking for the best upgrade options to get some more speed. I don’t want to spend a fortune as he may lose interest although I hoping not as I can relive some youth with this hobby.
