This is the spot to post up your Novak Crawler system experiences, loves, hates, problems, etc.
I just got mine installed and running on Friday. This is the first sensored brushless I have owned. I will admit that I was a bit skeptical. The initial impression- This system absolutely blew me away! There are ups and downs just like any other setup, but WOW!
I tried out the Novak Crawler system in The Beaver. The current build is pretty stable and solid. The weak links in The Beaver are probably the lack of servo saver (20mph crash breaks aluminum horns) and the Pede tranny diff gear. Narrowed Twin Force axles mated to Maxx sized wheels that are smaller than stock make the build near bulletproof and I can really push gearing in both directions if the motor allows. On to the specs.
Novak Crawler System (18.5 wind Velociti can, 2,700KV, 5 amp BEC)
7 Cell GP3700's
26.928 final geardown
Maxx masher tires
vehicle weight, estimated 10 pounds.
I ran this setup in a creek bed that is behind my house and at Capen park locally. I would give the top speed somewhere around 10-15 mph with the gearing I had. The slowest crawlable speed matched OR beat a super rooster w/ 55t lathe, Mamba w/ Outrunner, Quark w/ Outrunner, and tekin2 w/ 55t lathe. This throttle has the best resolution and feel I have ever used. It really made a slow crawl easier and fast speeds possible at the same time! It also has ZERO reverse delay. I could change from forwards to reverse almost 10 times in one second, I timed it. The motor obviously has a lot of power too. It is a medium can 380 shaft motor with a 2 magnetic pole rotor. The sensor makes the can a little longer.
A few things caught my attention during the setup and crawl. First is the drag brake. Even at 95% drag brake, it is nothing like the drag brake of an outrunner motor. I would equate it to the drag of an integy 55t with 8 tooth pinion through clod axles OR LESS. On a step incline the Novak Crawler system would allow my rig to careen down the hill at a frighteningly fast pace if I didnt control the rig otherwise. The second item that caught my attention is the "locked rotor dection" of the sytem. If you are giving any throttle amount when the tires do not move for a full second, the esc goes to neutral for 3-5 seconds. I remembered hearing that this would be taken out of the program, but it was not on my system. Combine the two issues and what do you get? A rig that tumbles back down rocks when you bind the tire for a sec and dont let up!! Not cool. Mark this system off my *comp worthy* list for now.
(The Beaver was propped against the wall and she rolled down and scared me just now :lol: ) So how did it handle? My rig was almost like a basher, fast and nimble but able to crawl sooooo slow and deliberate. This is THE ULTIMATE scale rig system!! Combined with a lower turn SS motor the Crawler programmed ESC would have even more punch and getup. Can this think break TLT axles? Yes. Can it break Pede internals? Maybe. Does it have the torque of a 2820 outrunner? Nope. But it can be geared fast, keep enough torque to crawl, AND have the super buttery smooth low end throttle resolution. Can you tell I am excited bout this? :twisted:
The hard numbers-- I crawled for an hour the first outing. Lots of full throttle bouncy action and lots of crawling slow. I immediatly recharged my battery and it took 2700 mAH. WOW! Thats pretty good for a meduim size rig with this kind of speed. The motor temp when I was done was 139F. Plenty of headroom on that. ESC didnt get more than warm really. Batteries were cooler than when I charged em, around 115F. I could gear up more If I wanted. I could also gear down considerably, as my pinion was 18t 32 pitch.
My opinion is that this is great system, even for the price. A comparable outrunner system would be comp worthy, lighter and cheaper, but not have the speed range of the Novak. A comparable sensorless inrunner setup would cost the same and have a higher power rating, but it would NOT be crawl worthy at all. The Novak fits into a perfect nitch of the Scale/ Trail/ Basher that can still crawl. Bottom line, I want another one.
