Hi currently own a hpi nitro rush with standard .15fe engine and looking to get a bit more power in it was looking at

hpi g3.0 - http://www.hpieurope.com/kit-info.ph...p;partNo=10411
or
the O.S. 18TZ-TX w/Rotary Carb - http://www.rcplanet.com/O_S_18TZ_TX_...p/osm11943.htm

my main issues that i am new to nitro rc and bit unsure. both engines high power 2.2 and 1.8 respectively but the hpi costs bout £50 less with more power is it really better and more importantly can a hpi rush handle that kind of power without ending up with a twisted chassis or broken gears? which leads to my next question what parts would need upgrading to cope.

Any suggestions gladly recieved also if anyone has a rush and has pics would love to see what i aspire to

OS.18cvr

cant go wrong with os IMO... good luck

Those HP number aren't even near being close to accurate. the TZ smokes the G3.0 without breaking a sweat. you really can't go by Manufacturers numbers. they lie!! OS engines are so much better than anything HPI puts it name on. they are easier to break-in, tune, they hold a tune better and produce alot more power.

Yak hit it right on the money when it comes to the numbers that the company's put out, OS all the way

Thanks for the advice. Silly question but are the rear wheels meant to be angled in at the front and wobble in rotation or is something wrong cant figure out what as checked hpi site for instructions and no help everything is where it should be but seems iffy? any ideas what hop ups to match os engine?

thanks again

angled in yes it makes the car drive strighter or something i forget... but not real wobble thay can be wobble just a little bit becauce there goin to be some play after wear on the rods and hubs if its messing up your stearing then you might wanna change them out... it also could be bearings or shafts in the wheels are bad most likeley not tho... bent rims... could also be from your stearing rod ball caps an balls too... it might be a little bit of all them togather that gives you all the wobble just make sure you know where its comeing from.. my losi xxx-nt has wobble in the front tire ever since i hade it and i replaced everthing on that car more then twice so its up to you if you can drive with the wobble and it dont bother you then dont wory about it... good luck

cheers everyone just went to start the damn thing no joy then realise the glow plug shot and shops shut damn got to wait til monday to drive it after total rebuild and clean I am gutted that a stupid little thing is stopping me from driving it must admit i dont know if should bother with new engine for £100 or just get a new car for around £200 any ideas what to get? want basher that will survive my gran turismo style of driving  (love no damage) basically i want a tank that can survive my incompetance but also will want to hopup in future 4wd for preference but open to 2wd what do you guys think?
