BAMF SAVAGE Posted August 3, 2016 Share Posted August 3, 2016 Hello all, I have a HPI Savage that has had a catastrophic engine failure, sad times so, it's time for a new one, the old is a 4.6, I'm toying with the idea of a 5.9, but I need some advice, do I replace like for like, as in 4.6 or more grunt with a 5.9, have looked at Hong Nor 5.9, fairly priced, HPI 5.9 and 4.6 are pricey, and above budget for immediate purchase, I also looked at the STS D30M again, fairly priced, so which is best, has anyone got experience of the budget motors any and all advice welcome cheers ?

Nitroholic Posted August 3, 2016 Share Posted August 3, 2016 First off.... the Hong Nor 5.9 and the HPI 5.9 are both the same engine. Both are just rebranded Force R.36 motors with afew cosmetic alterations. Secondly.....it's not a very good engine. They have a history of reliability issues, with a speciality in busted conrods. They also don't make as much power as you think.....and also drink the nitro a lot faster. I would not advise using one. If you want to go the Force route...I would suggest going for the 5.2cc .32 unit. It's better balanced in a Savage, gives about the same power, and gets longer runtimes. I have had one in a Savage for a while, and it's been rock solid. It's getting towards the end of it's expected life....but it still starts well, runs sweet and holds a tune. Just seal the backplate and carb neck with some silicon instant gasket, coz Force don't bother to make them very gastight. 17/47 gearing and it's spot on. In all honesty...if you set your mind to a 5.9 and were looking to spend £125....spend another £25 and get the LRP Z30 spec2. You will be glad you did. More power, better quality nad solid reliability. I have a couple of STS .28's that have behaved well, but you do have to be careful as there are a lot of low quality copies of these engines. Get a good one and they are fine. Get a knock off and it will be rubbish. Mine are run as a pair in a Twinzilla and have given no trouble. Just be careful about your choice of retailer..and REALLY read the feedback. Quote Link to comment Share on other sites More sharing options...
BAMF SAVAGE Posted August 4, 2016 Author Share Posted August 4, 2016 Hey, Thanks for the info, that's really helped a lot Quote Link to comment Share on other sites More sharing options...
stevo2551 Posted August 4, 2016 Share Posted August 4, 2016 I have the 5.9 in my savage x, it was a pain at first with a fair bit of tinkering....and swearing involved due to starting and running issues. Once I got it all sused out it's been fine and beats my mates 3.2 up on the quarry. That said it's still temperamental when it wants to be ? but that's all part of rc cars. I would probably look for a different motor when this one goes Quote Link to comment Share on other sites More sharing options...
BAMF SAVAGE Posted August 5, 2016 Author Share Posted August 5, 2016 Thanks for that, will bear it in mind, I'm seriously considering the LRP Quote Link to comment Share on other sites More sharing options...
