Jambo.26 Posted December 29, 2019 Share Posted December 29, 2019 Hi i bought a nitro hpi trophie buggy years ago but really struggled with getting it set up. I recently converted this to the flux version with a hobbywing ezrun max with 2200kv motor combo. I’m wondering what’s a good battery option and gear set up for a young child to get use to and not smash it up on his first outing. Thanks in advance Jamie Quote Link to comment Share on other sites More sharing options...

It's quite a powerful combo for a child so your best bet would be to limit the throttle range to reduce the top speed until they have the hang of it 1 Quote Link to comment Share on other sites More sharing options...

That's a hell of a lot of power for a young child. Definitely let them only use it in an open space 👍 Quote Link to comment Share on other sites More sharing options...
Jambo.26 Posted December 30, 2019 Author Share Posted December 30, 2019 What would be a better motor option 🙈 Quote Link to comment Share on other sites More sharing options...
fnknan Posted December 30, 2019 Share Posted December 30, 2019 Well is it just for the child or will you be using it too? Quote Link to comment Share on other sites More sharing options...
Jambo.26 Posted December 30, 2019 Author Share Posted December 30, 2019 It’s more just my son. I actually bought another for myself 🙈 when I was having nitro issues. Also what’s a good radio for limits. For this car I just have the stock HPI unit that comes with the car Quote Link to comment Share on other sites More sharing options...
babylon Posted December 30, 2019 Share Posted December 30, 2019 That motor will be fine, Its an RC Car, Not a Kalashnikov. On 2s it will slower than a 1/10, So will be OK. Quote Link to comment Share on other sites More sharing options...

Definitely wouldn't trust myself as a young child to handle 3s power even on a 2200kv motor 😂 Edited December 30, 2019 by fnknan Quote Link to comment Share on other sites More sharing options...
m4inbrain Posted December 30, 2019 Share Posted December 30, 2019 It all boils down to where you're running it though. I wouldn't hand a kid a 3s RC in a public park, but where i run my RCs, there's usually no one else for a mile or two around me. I don't see a problem in that case.

m4inbrain Posted December 30, 2019 Share Posted December 30, 2019 That, or run it on 3s, get a somewhat decent radio and limit throttle to like 50%. Or, just run it safely away from anything that could be damaged/hurt and teach your kid responsibility. Quote Link to comment Share on other sites More sharing options...

m4inbrain Posted December 30, 2019 Share Posted December 30, 2019 The DX2E Active? The DX2E Active has throttle limiting via switch on the top. This one. The older DX2, i wouldn't know. But in regards to size, the Turnigy GT5 springs to mind - we recently had someone who bought the GT5 for his kid which had problems with a spektrum radio due to the size. https://hobbyking.com/en_us/turnigy-gt5-6ch-2-4ghz-afhds-2a-surface-radio-w-gt5-receiver.html Quote Link to comment Share on other sites More sharing options...

RCbutcher Posted December 30, 2019 Share Posted December 30, 2019 It's an adult rc built for adults lol. Get another and blast them together I say. But something 2-3s for your son. A 1/8 buggy has the weight and needs good power either way so probably not the best chassis to go with. But can be done so long as you always supervise etc. Or you could probably trade it for something more suitable too. Something 1/10 4x4 brushless.
