Will this motor/esc combo work?

[eovnu87435ds]

I just bought this CRT.5 with the extended chassis today!
http://www.rcuniverse.com/market/item.cfm?itemId=535537

My question is, will a MM and an aveox 36/15/1.5 (3768 Kv) be enough to power it? or will I need a bigger motor?



Also, on a different note, the RC-Monster battery box listed here, http://www.rc-monster.com/proddetail...MFPbatterytray

There is a specific option for the crt.5, and in the description it says it is specific to the rc-m chassis kit. Is that because the ofna extended one has the little lip at the chassis edge? and will it accommodate 2 2s packs?

You got a good deal. I didn't.



Make sure to look into the revo/jato shocks. I got 4 extra shocks with a used jato, and I put them on all four corners. The only mods I needed to do was replace the metal bolt holes with the ones from the old shocks and put a washer between the standoff and shock tower in the front. The metal ball/bolt hole things just pop out with a hammer/screwdriver and pop in with a pair of pliers. I don't have a way to mount the body in the front, but I'll get er done eventually.

Enjoy your .5!

The rcm crt.5 battery box has predrill mounting holes in it to fit Mike's chassis kit. It is also designed as a lay down battery box (center diff is moved over for room on mikes kit). I don't think it would fit well on the standard pro chassis but I could be wrong. Most people seem to have their batteries standing up if not using mike chassis.

Def not room to lay a battery flat on the Ofna chassis, barely room to stand one up! I made my own battery tray out of aluminum, my lipos have a huge heatsink! I don't know anything about the aveox motors but a Medusa 50mm is plenty adequate!

[Metallover]

You don't plan to run "aveox 36/15/1.5 (3768 Kv)" on 4s lipo, do you? I'd look for something (medusa 50-60mm, Neu 1509/1512) around 2400-2800kv if you plan to run 4s all the time. It would probably get very hot running that aveox.

[eovnu87435ds]

aveox is the predecessor of neu motors, and are of the same-ish quality. in fact, it is on the way back from neu repairs now

[Metallover]

That's still 55,750rpm. Aveox motors seem to be rated for 50k. I'm pretty sure anything much over 45k will run pretty dang warm and anything 50k+ will run hot. I may be wrong though..

[eovnu87435ds]

metallover, what is your motor choice, voltage, and gearing, and possibly theoretical top speed from brianG's calc

also, a traxxas 2075 servo w/ 125 oz torque should be good enough, right?

[Metallover]

Well I run the medusa 36-50-3300 in my .5 on 3s lipo. It's geared 13/46 which is for 38mph. Temps are about 125 motor, 135 MM, 95 FP 30c 3300mah.

Ideally, I would go for a Neu 1512/2D (2550kv) on 4s lipo; geared for 45-50mph.

I'm not trying to say your aveox sucks, I'm just suggesting other stuff.

[eovnu87435ds]

i know, i just want to get a feel for a decent setup and speed range and stuff. assuming the tires are 4 inches, which gave your setup 37.9mph, I calced my motor on 3s, 12t pinion and got 39.95mph. I want around there because ideally i want to take this on the racetrack. I guess time will have to tell if this motor will do or not. If not, I will definatley be looking for a neu motor. Neu has an offer that will let me trade in my Aveox motor and get half price on a neu, which would bring the price down to just under $115

[Metallover]

Well on 3s that'll be a strong motor. I thought your heart was set on 4s... 4s would be cooler and faster though, so the neu trade in would be cool.

[eovnu87435ds]

I have 2s packs that are mine. I also have 3 zippy 3s flightmaxes that arent mine, but a friend's who has nothing to run 'em in, and who's dropped off the face of the earth. there was 4, but one blew up in ben's matrix a little while back if you guys remember... just randomly, poof.

I just thought 4s because then i dont have to buy more lipos!
