Electronics Help

[0260b4u007]

Hey guys, new to this site. I have a venom creeper, had for about a month. Selling to my brother and ordering a gmade. Can you help me pic out some electronics. New to rc stuff, and thats what i struggle with.

R1 will have dig, and rear steer. Need a motor, that will be ok for crawling, but would love to have some umph like a rock racer too. Dont know if brush or brushless would be better. I have the servos already, but will need everything else. Give me some suggestions.

thanks,
Donnie

I keep looking at the new airtronic six channel stick radio endless possibilaties!

Depends a lot on whether you will 'Y" split the servos for the steering or use a 3rd channel.

If you are going to split the servo's 'Y' style then you can use the 3rd channel for the dig servo.

A Spektrum DX3C is a good budget 3ch tx/rx.
ESC maybe a Novak Rooster or Novak M2.
Motor wise you need something between 35 and 55 turn I would say. From what you say 35 might be more your thing. I run a 55 so can't really point you in the right direction but mine is an Ansmann 55T.
Battery wise try to get something that you can mount on your axle for the cog.
Something above 3300mah, 30C or you will notice the lack of power/torque. Losi do a crawler specific lipo that meets the above.

like I say i am new to this. But if i split like you are talking about, would it be all time 4ws. And i wouldn't be able to crab walk would i? and you saying i need a 35, i guess the smaller the number the more speed?

thanks,
Donnie

Your right the lower the number say 35t would be faster then say 55t, the lower the more speed the higher more torque. Have fun and good crawling from Wyoming.

I run an scx10, rooster esc, 55t rockstar motor, dual 2200 2s mini lipos in parallel. Just started this rock crawling thing, so learning this thing too.

its a blast for sure. thanks for helping me out. I have the venom creeper ow with a 55t motor as well. good luck crawling.

thanks,

would the t35 still give me some torque fro some light crawling?

[tcrawler]

I have a 35 turn in my r1 and my swx ,plenty of torq, you can also play with gearing to get the torq u want for crawling.

[northernerbill]

Agreed, 35t would be great, I run a 55 as I say but am thinking of going to about 35.

Yeh the y split would mean full time 4ws but will you use the crab that often?

I tried it successfully and found it an extra you don't need or use.

A suggestion would be 2ws with a dig unit or 4ws full time. The latter though is not allowed in competition.

2ws with dig is really good for really tight turns

thanks, with it split would i still be able to turn the 4ws off? No competitions around my parts, so just competing against brothers & buddies. For the guys that do run the 35t, would this be fats enough for jumping and rock racing?

thanks,
Donnie

[northernerbill]

You can't just turn 4ws off no as the servo would then free wheel when knocked basically.
I'm in the same situation so when the time ever arrives that I compete I would remove the rear servo and attach the then loose arm to the servo tray so it's rigid.
35t plus a pinion above 15 should see you belting around.

Mine is set up as a rock racer, i have got a tamiya tz 23t brushed motor,2 and 3 cell lipos, castle creations sv2 esc witha 14t pinion, it does lack top speed. I got the 17t pinion but i haven't got round to trying it out. The burst of speed(o-60) is great and the motor has got quite a lot of touque. It wont have as much torque as a 35t or greater but the speed makes it a bit more fun.

thanks guys big help!

I just got mine together,running for the electrics is a tekin esc with a 35 turn integy normally i run 2cell 1600 30c when i want to pickup the speed a little i run my 3cell 35c 1100, running the stock 12t pinion, i might go up to a 14t pinion? i can still crawl with good torque an nail the throttle an kickup some dirt if need to. these rigs are excellent! trail,bash,crawl, they can do any of them.

[0260b4u007]

exactly what i needed to know crawler. Ho tthe motor figured out. got the servos already, need to find a servo for the dig unit! shouldnt be too hard though. How many channels will i need for rear steer seperate, and dig? im guessing two channels, so that puts me up to needing 4 channels?

thanks,
Donnie

[crawlernut]

Iam not too sure about doing dig an 4ws, I would have just one or the other, the 4ws is gonna be like having dig, both together is gonna require a 4channel radio, your right about that. I never had 4ws or dig, I just goose the throttle a little when in a tight spot,lol, the small tight r1 chassis is tough getting just a motor esc an rx in there let alone add more like dig an more wiring an dig servo,whew! it would be tight!

[northernerbill]

I've got 4ws and dig and to be honest it doesn't work that well combined.

Example being lets say you've got dig on to descend BUT you also need to turn, yeh great its digging in slowing your descent BUT because the rear wheels have turned as well the car tends to go in a straight line again due to the rear wheels fighting the direction.

To have one over the other would be DIGGGGGGGGGGG!!!!!!!!!!! every day of the week, its a brake and steering aid.

If your in a tight spot and need to control 2 extra channels on top of throttle and steering your gonna fluff it up trust me.

[0260b4u007]

thanks guys for all your help, probably doing the dig! and i don't comp or anything just like having fun on the rocks when we go rck rawling in the big rigs.

thanks,
Donnie
