Hi guys. I'm having trouble with my servo tray. changed from a stock to a carbon fibre. The problem is that the servo for the throttle doesn't quite fit. I bought an alloy one with servo savers hopeing they would reduce the size of hole allowing the servo to fit snug. This was no use. Can I buy servos that size between standard and 1/4 scale? I also tried to apply my hitec hs-805mg servo but it's to big. A king cobra ss001mg fits perfect. Any help appreciated, thanks.

Is it possible to shoe a 100cc chainsaw lump into the chassis, i notice youtube have shoehorned 62cc twins in so a 100cc shouldnt be much larger right ?

how hard is it to convert a buggy to shortcourse or shortcourse to a buggy.

can you fit 2 speed boxes to the hpi baja's or they just fit the king motor types, can/is there a three speed box and why do most not run two speed boxes

[creamsodauk]

2 speeds will fit hpi and clone bajas, they arent all that popular due to the fact they require more maintenance and arent great off road. they are mainly used for on road speed bajas. Probably more for show then actual use. and no their isnt a 3 speed.

as for the engine, a 100cc chainsaw engine probably dosent deliver much in the way of power, the 62cc is made by a company and has oddles of power. but a chainsaw engine will be a low revving lump. it probably can be done but i see no advantage

Yes there is http://www.gtbracing.com/?p=570 just a bit pointless

wow am loving that three speed. damn that thing shifts along.

well being a landscaper i come across a few dead old chainsaws and weedwhackers, so was thinking of a homebrew port and polish to give them back some life, maybe just come across one thats a diamond and worth using.

chainsaws are high reving machines, they need to be to keep those teeth chewing. weedwhackers tend to be lower reving.

Wont be as high as a rc specific engine mate plus the lower the cc the higher the revs mate.

I dont get how these multi speed gears work off road.
As when you hit a bump and the rear wheels lift dont they just change up ???

So lets say you've just pulled off in first, hit a bump so it changes up then when you land the revs bog so it changes down to first again. Or am i missing something ????

[Mark7616]

There not very good offroad dave you need to either gear it to change pretty much straight away or have it come in right at the end.  On a track it would be useless over jumps etc.
