mo99y Posted November 22, 2014 Share Posted November 22, 2014 Hi, I have an old Boomerang I am trying to resurrect. Just tried running it round the garden, and it seems to be much slower than I remember. Are the 15-20 year old NiCads likely to be dead? Just gave them all a long trickle charge, and only got low speed and short running time. If they are, as I expect, no longer useable, am I best to swap to NiMh batteries, and are these ok to use with the mechanical speed controller? I also guess the old, original 540 motor is probably a bit worse for wear and storage. If I should swap this too, what would you recommend. I was thinking about the Tamiya sport tuned motor. I do not want to destroy the cars gear boxes with an OTT motor. It is all ball raced. I do not want to throw lots of money at the car if, it is probably just better to get a new low end Tamiya (Neo Fighter etc).I have already had to buy a new chassis and front wishbones, which have been damaged in a house move. To but a new ESC, and Motor would have put me in the cheap new car territory!!! Thanks for any help. Rich Quote Link to comment Share on other sites More sharing options...
RCpete Posted November 22, 2014 Share Posted November 22, 2014 Stick a mild brushless setup in it, the gears will be fine. I have one in my old DT02 chassis, a 3300kv motor and run it on 3s and its fine Quote Link to comment Share on other sites More sharing options...
nr73 Posted November 22, 2014 Share Posted November 22, 2014 I did everything you describe to my old Tamiya buggy recently. NiMH will be fine if you were on Nicads, I'd suggest getting some newer batteries though and a decent charger but that isn't needed right away. If it's any use, this is what I did; - Replaced motor with Tamiya Sport Tuned RS540 Quote Link to comment Share on other sites More sharing options...
mo99y Posted November 23, 2014 Author Share Posted November 23, 2014 (edited) I think I need to 'brush up' on brushless motors before I plunge down that route. For now, I have ordered a couple cheap 3300mAh NiMh packs, a new carger, and the Tamiya Sport Tuned motor. Maybe an ESC will be the next step!!! Maybe even a brushless motor - but perhaps a newer car would be better for that! Thanks Edited November 23, 2014 by mo99y 1 Quote Link to comment Share on other sites More sharing options...
nr73 Posted November 23, 2014 Share Posted November 23, 2014 The Hobbyking ESC is a great, cheap replacement for the MSC at Quote Link to comment Share on other sites More sharing options...
mo99y Posted November 23, 2014 Author Share Posted November 23, 2014 Thanks, I will maybe consider that for a next step!!! It seems a bit of a bargain. Quote Link to comment Share on other sites More sharing options...
