Hobbyking does have some rebranded Hobbywing controllers, but again you must be careful as several of these are not real Hobbywing controllers. The Turnigy 18A, 35A and 60A are built by Hobbywing, but the Hobbyking brand and Turnigy Trackstar series are not, even the ones that look the same. I have heard too many complaints about their reliability for me to trust them. The 18A Turnigy works great in the RC18 as long as you dont go crazy with the motor, and the Turnigy 35A has the same footprint as the 25A EZrun but has a taller heatsink with a fan. I use the 35A in my larger minis with larger 380 size and mild 540 size motors, I removed the fan for extra clearance and it still never gets more than warm. This is a good option for the RC18 if you cant find the 25A for a good price, or if you just want the security of knowing you have more than enough ESC.

Default Motor kv

I have been reading all of the different posts on here but am still unsure what kv motor I should purchase. I am likely choosing one of the hobbyking combos but trying to decide on the 5200 or 7800 kv. I plan on running the truck exclusively on 2s or a 7.2 Nimh pack. I believe the 5200 would give me A optimal rpm of 38k but it seems others are running a higher kv or 3s pack. That logic works with 540 size motors but maybe not with these smaller ones.

I plan on building this as something to drive between races at the track on and off road.

I've run the Castle 6800 on 6 cell NiMHs for a while and it's great. 2S LiPos would be a tad faster. If you're never going to run 3S then get the 7800.

Which 6 cell packs are you using with your Castle? What esc are you using? Do you ever get any hesitation or cogging? What are your run-times like? I would really like to know, thanks!

you would be happier with the 5200, It might not blow your diff out but it goes pretty fast.

Default Brushless system

Thanks for th responses so far. I should add that I want something faster than stock but I am not looking to set a land speed record either.

6800 range is where you want to be. Anything higher will not have the TQ off the line. I have a 5400 and a 9600 Castle, and the 9600 is just too fast for my local track. (running a 6cell NiCad) i have it geared way down, and it still has no punch TQ out of the corners.

They were GP1100 packs. They got old and had to be tossed just recently. I never really timed them but if I had to guess I would say at least 15min of bashing maybe more.

Currently I'm running one of the castle CM26/4600KV motors on 3S. To much power though. I think it messed up my diff balls/plates. It's just silly. No traction at all. It just skipps across the surface with all 4 tires ballooning. Hard to control. Plus it gets my poor old Mamba-25 ESC too hot. I had a little cogging when I forst installed the CM26 but it seems to have gone away. I don't remember ever having cogging issues with the CM20/6800. I may go back to it.

I just ordered a DP steering link and a 3racing servo saver spring. I hope to set this thing up for LM oval racing and show the 1/10th guys what's up lol.

I actually have an RC18T2, but I like to read the posts here on what guys are using on the original kits. I have been back and forth between a Novak Mongoose 10.5 system and the Castle Mamba Micro Pro w/CM20 6800kv system. I like the low end torque of the Novak, but the Castle actually seems faster to me (seems to have more top end "pop"). Just took the Novak out again and am back to the Castle, so I saw your post and was curious how you liked yours. The Novak is smooth, but I think I like the Castle better overall. I expected the opposite, since the Novak is a 380 sized motor. Go figure. Thanks for the reply.

I just got a RC18t but want it more for off road. People are saying they use 10 scale touring car wheels. What wheel adapters are there? I know, obviously I'd need hex's but that little axle pin doesn't seem large enough making the wheels a little sloppy??

go with Kyosho 1/16 buggy wheels/tires and the adapter, It was the happy medium for me, the wheels are more narrow and dont have as much strain on the drive train, you can see a pic in my for sale add....they really look sick on the truck imo.

I just ordered the Hitec hs65mg and am slightly worried I won't find a screw to fit it proper to the saver. Can anyone give me a link to what I need to make this work?? Apparently it's a 2,3x8mm machined screw.
