Need some R/C advice - RC-Monster Forums

So ben found this ad on rcuniverse about a 1/5 scale monster truck, RTR gas, and he is looking for a flat trade for a 1/8 scale brushless offroad rc. he sent it to me jokingly, but I am starting to consider it. I already have a motor and speed controller thats up for the job, so all I'd really need to do is make a motor mount, find me a pinion, and install electronics and lipos. I always love doing the conversions, and working on a "project" truck...

I currently race, and even though it is a points series, I don't care, I do so for fun. I am not sure if I could race the 1/5 MT at the track. If i could, it would be in sportsman class.

I also have a crt.5, that would be busy raping the 1/10 class until xmas time, when I will do the rc-monster conversion, and see how it faces in the full size truggy class(evil laugh)

So, what do you think? should I trade my converted hyper 7 pbs for it? here are pics of the MT, it is a smartech titan 1/5 Monster Truck, and you can find pics of my hyper in my sig.

Its a big lumbering turd, its no track racer. That big though its worth every penny to look at it. Dude must be broke or want to run a track. Its not a really practical truck but sitting on the shelf even would give you a woody. I love gas RCs, 3 pulls and its running for hours. Granted gas isn't the bargain it once was. So long as it isnt nitro !!!!

Prolly not a bad deal if he doesn't want your lipos and charger. I don't know if I'd bother converting it though. A 1/5 brushless isn't gonna get that good of runtime, you'd need a lot of huge lipos where leaving it alone you can run almost all day for less than $5 with no downtime

true, but as long as the conversion i create is a drop in solution, If it doesn't work out with the motor and esc i have, i can swap back to the gas until I come up with something else.

Also, this would be my first non-electric rc lol. does it loose it's tuning as much as the nitro engines do?

Gas engines hold a tune pretty well, pretty much just like a weedeater or chainsaw engine. If you want to run in winter and summer it will need to be tuned for maximum power but shouldn't be much different. My chainsaw just requires flipping a plate so the carb sucks in pre-heated air that passes over the motor.

E-Revonut · 09.08.2009, 12:13 AM

Only downfall is that by the looks of it that's only 2wd

eovnu87435ds · 09.08.2009, 12:13 AM

nope, 4wd

E-Revonut · 09.08.2009, 12:15 AM

Go for it then!!!

All we have are 2s packs, he only has one pair of 2s for a total of four...

the esc and motor arent the best but they should move the truck.. Big @ss brushed motor and a robot speed controller. only downside is that it is forward-revers only, no brakes... and that the motor has brushes

I honestly don't see that truck moving at more than 15-20MPH on 4s, keep it gas! Gas ain't nitro!

eovnu87435ds · 12:27 AM

by the way, this is the motor:

It is 66mm in diameter, and 110mm long, with an 8mm shaft(fits mike's mod 1.5 pinions), and weighs 46oz and is 443kv. It is the same size as a neu 22xx series motor, but is brushed. It will be plenty of motor for a truck that size.

the speed controller is a robot controller, that has fwd and reverse, and can handle up to 6s lipo.

and ben, we do have 2 un-matched 3s lipos. while that would be bad to run, it would be ok to run a 1 minute test to see if it is worth me investing in some 6s turnigy lipos

E-Revonut · 09.08.2009, 12:31 AM

I'd still keep it gas! He could run all day as long as the receiver pack held out, hell he could use a bec/voltage regultor and use his 2s packs for the receiver packs and he could def run all day long instead of 20 minutes

jayjay283 · 09.08.2009, 12:35 AM

have you driven a RC gas car/truck. You may not want to convert it. At least give it a shot. I know the whole premise is brushless, but the gassers are pretty fun and reliable. Noisy yes, daytime driver for sure but a few tweeks they go 88mph. I understand why you would want to convert it I would too, but after a few gas runs you may be thinking its not so bad but I want my brushless buggy back for midnight maurading... So my final decision is stick with the brushless unless you can afford to play with gas too... Final decision,, Judges ?

BrianG · 09.08.2009, 12:45 AM

I can't believe I'm gonna say this, but I too would keep it gas. It's not "nitro" so it falls into that special niche between the "perfect" world of BL, and the icky world of nitro.

Then again, you have a motor/ESC for it already. Don't know how you're gonna set it up so the mechanical brakes don't activate when you go into reverse (unless you disable reverse, but then you don't have reverse). And batteries are gonna be a challenge to find a setup that will give decent runtime without spending a fortune.

Either way, I'd get it. The BL/gas decision would be a little harder for me. At the very least, I'd try it on gas first and see how it works for you and decide from there.

On second thought, how is parts support? That would be a big consideration for me to get any vehicle.

IIRC that's a Carson-devil/Smartech-titan/Hurricane-c3.

I would steer clear of it. I was seriously looking at getting this truck and asked lots of people there thoughts on it and nobody could say it was a good truck, great to look at but a shit make.

The stock motor needs replacing, it doesn't have the torque or rebuild-ability of a chung yang or zenoah though it does have a tuned pipe already and they make a big difference. The radio and electronics are all base model, cheap and nasty. The cvd's need upgrading the centre diff has been a pain in the ass to people who owned one and if you go brushless I doubt it will handle the torque. Plus, the general quality of build leaves some for desire (it's a smartech).

Having said that... it is a good looking truck and I do not own one... I have a baja.
