Monster Truck Madness – Questions about Dual Motors
Hey gang and Happy Thursday! I acquired a pair questions final week from a very long time reader and I’ve been which means to speak about one of many subjects for awhile however didn’t know the best way to slip it right into a column, so that is the right probability. These questions come courtesy of “The Trail Rat”.
I get into radio management monster truck racing largely within the sport mod and Pro Mod class ultimately perhaps mega truck. I’m on the lookout for any data or video or web site that may assist me to study racing normally largely the tuning like I do know the shocks will be tuned gear ratio 4 hyperlinks and weight stability?
Congrats on deciding to become involved racing a monster truck! Now as for the query(s), there’s lots there. I’ll give attention to the shocks half.
For those that are unaware of the distinction between Sport and Pro mod lessons, whereas the principles differ barely from membership to membership, normally Sport Mod is stricter on battery guidelines and limits racers to brushed motors solely. Typically 2S and someplace within the 17t vary. Pro Mod is extra open, with huge energy and better voltage.
There are numerous chassis on the market, so tuning a light-weight Axial SMT10 versus a heavier Losi LMT will clearly be completely different. rule of thumb I take advantage of is that I begin out with 30 weight oil and begin adjusting from there. Given you might be simply beginning to race, I dunno that I’d advocate you exit and get loopy with swapping springs and different issues (although you’ll be able to in order for you!), I’d maintain the variable restricted to only the oil at first. Or perhaps maintain the oil at 30 weight however experiment with 2 gap and three gap piston shocks. Whatever you do, attempt to solely change one factor at a time to raised perceive what you want and don’t.
But hey- if you wish to get loopy and construct a customized Frankenstein shock absorber utilizing numerous producer components, oils, and comes then speak to the monster truck shock man- Jeremy of Taurus R/C Monster Truck Racing. His vans land like butter and he’s continually tinkering looking for the right shock setup. Send him a message and he gives you the lowdown!
Let me make a advice to you that’s NOT shock associated though- get a set of JConcepts Renegade tires and Slam-Tech closed cell foams. You will remove tire bounce. The distinction from open cell to closed cell foam on a monster truck is so pronounced that it nearly makes it deal with like a brand new truck!
On sport mod is it price it to make use of two brushed motors on an smt 10 or only one.
Ah sure, that is the subject I had been eager to weigh in on. The Axial SMT10 comes customary with one motor. Those wanting extra energy may merely simply improve it to a brushless system. Racers who have been restricted to brushed motors, often with a flip restrict of 17, couldn’t do that. Plenty of racing golf equipment permit a max of two motors to accommodate Clod Busters, so in following the established guidelines racers began including a second motor by the use of a twin motor mount plate.
This REALLY modifications the texture of a brushed SMT10. Whereas with a single brushed motor the vans are down on torque, two of them supplies an enormous improve. So a lot so, that it nearly appears like driving a pro-mod with them. The vans are faster and sooner, but additionally trickier to deal with.
I’ve hesitated on switching my Sport Mod vans over to twin motor for the latter reason- the vans are simply simpler to drive with a single powerplant and I’ve gained a great deal of races by preserving my truck clean and in management. This previous 12 months although, as increasingly more opponents are going to twin motor, I discover myself being outgunned and shedding races due to it.
I ordered some twin motor plates from eBay and plan to improve quickly, and once I do I’ll talk about it right here. I plan to make use of two JConcepts Silent Speed 17t motors and a Hobby Wing 1080 ESC.
Ok Trail Rat, I hope this data helps ya! If you will have a query(s) that you just’d like answered right here, shoot an e-mail to doug@bigsquidrc dot com.
Until subsequent time, maintain it on all 4’s!
