hello all!
i'm new to this forum, but not new to the hobby. i just spent waaay too much money and waaay too much time (about 4 years) rebuilding a project .21 original savage and i'm finally DONE!!!
that's the cool part (see pics below)...
the not so cool part is it's incredibly SLOW. it doesn't even come close to poppin the front wheels up and it barely even roosters in the dirt. my drivetrain is all brand new and spins like silk, nothing is binding at all. i have a Werks adjustable racing clutch kit with carbon shoes and it's set to engage at low to mid RPMs. however, my mill may be the main problem. i'm running a stock HPI .25 (with a different cooling head and integy intake). it doesn't seem to have any power or torque at all. the motor has decent compression, but it's used.
my other thought was, gearing. where should i be? i'm running 50SG and a 15CB which should be plenty tourqey. i wanted mostly grunt for climbing, bashing, jumping and acceleration, but i got nothin. my other problem may be the enormous and super heavy beadlock 40 series tires i chose for the truck. i just wanted something big, but these things have bad wheel hop at speed, and they're just soooooo heavy.
lastly, maybe that racing clutch just can't handle the weight of the truck and move those big 'ol tires around. my truck has never been weighed but i bet it's close to 20 pounds with all that aluminum. i know that clutch i have is meant mostly for lighter weight racing buggies (eighth scale buggy and truggy) but i figured if it was adjusted right, it would do ok with the carbon shoes (most grippy).
i have been in the hobby for 20 years, but this is only my second nitro. i had an RC10GT that tuned up easy and was a rocket. but i just can't seem to get any power out of this setup. i've youtubed some savage vids and there are trucks out there that just plain RIP.
can anyone shed some light? my main three questions are:
-am i using the right clutch or should i just go with an aluminum 3 shoe?
-is my motor just plain junk or too small for what i'm running?
-am i in the right neighborhood with my gearing? i want mostly torque.
the dimensions and tire size of this thing pretty much make it an XL. it started life as a .21 back when that's all you could buy. but it now has the 1" lengthened chassis plates and 14mm to 23mm extended hub adaptors that add about an inch and a half to the overall width of the truck. so it's an inch longer and an inch and a half wider than a stock .21 not to mention the massive wheels and tires that are on it.
any help would be great. i know there are quite a few motor options, but i don't know which one to invest in. i'm looking for one that's going to move this beast around with authority. maybe a picco .28 or an axial .28RR?
so what SG and CB? what motor? what clutch? THX!!
