| Bowhouse N2R high clearance skid and setting gear mesh
I installed a Bowhouse N2R high clearance skid yesterday on my TRX-4 crawler (started life as the TRX assembly kit with 2-speed trans and selectable lockers). While I had the motor off, I also changed to a 10T pinion; a Robinson Racing hardened gear. I mounted the gear mesh adapter on the motor to "B" as per the manual. Driving it around it was really loud, much louder than it was with stock parts. I felt based on the loudness that the pinion/spur mesh may be too tight. So I changed the adapter back to the "C" setting it originally had. You can probably see where this is headed. Yep, I destroyed the spur gear in just a few minutes. Someone at the crawler course said he used to have a TRX with the same N2R skid and had the same issue--very loud. He said he tried numerous brands and materials of pinion gears but it was always very loud. He said he had also ran a 10T pinion and used the "B" setting with no problems. He theorized that there's something inherently "off" with the skid in the way the motor sits in the slot in the skid leading to the much louder operating noise. What do you think--go back to "B" setting per the manual? Is there a way to reduce the noise? Has anyone else had this same issue? It's the first time I've heard of it in all of the reviews I read.

I'm running one in mine and it's definitely noisier than the stock skid. I use an alloy motor mount and a 8t pinion with the stock spur, which is a bit noisier to start with, but the BowHouse skid made things even louder. I think in part it's the different plastic and also the 1-piece design seems to resonate the gear noise more. The benefits outweigh the negative of the noise to me. jim |

I have used all the versions from prototype up to the current V2 and the only time gear mesh was an issue was on the early prototypes when using aftermarket motor mounts. It was discovered some aftermarket mounts have variances in the depth where they slot into the skid and caused mesh problems. A revision was made early on and I have been running a GRC motor mount with the skid for quite a while now with no mesh issues. I'd say if you are getting good mesh with the B hole and not overly tight, then keep running that setting. As for the gear noise, can't say I've noticed if there was any more than stock since the Revolver drowns all that out. |

Yeah, no denying that those Revolvers are loud. They don't bother me but some of the folks I crawl with get all twisted over it. Of course, I haven't heard anyone disputing how well they perform though! | ||

Early version: Current V2: As for the motor plate, I really like it. It takes a way all the play between the motor plate and the clamp that secures it (some trucks have this issue more than others) but the ability to check mesh while everything is installed is the biggest win. | |

Mine's a V1, but, like svt', I run a GRC (copy) motor mount. It really helps with gear mesh, and makes it easy to grease 'em without tearing anything down too. May have to get a V2 now. jim |

So based on your previous comments, my V1 should still work with both the stock Traxxas plastic motor mount and the Traxxas aluminum or STRC mount? I looked for the GRC mount to order but it looks like I'll have to get it from China direct. Normally that'd be fine but I'll be running in another comp this Saturday so I need to fix the truck right away. | |

What brand copy did you buy? I've never had a copy of Chinese-made part before. Is the quality the same or does it get worse, like say when you photo copy another copy of a color image? Last edited by RCTom; 03-09-2020 at 02:10 PM. | |

In the meantime, I picked up an aluminum Traxxas motor mount so I can run this weekend. I guess now I get to do some product comparison testing in the near future. But the GRC (and it's clones) are already one point ahead in scoring due to the removable inspection cover. | |

I have the GRC motor mount and it helps a lot allowing some access but XtraSpeed have an interesting mount. There are plenty of aluminum motor mounts available but this one is attached to the aluminum lower spur gear cover using a screw. This leaves the whole pinion and spur much more open than the GRC mount for checking engagement and mesh clearance. Having the aluminum lower cover "might" even help with the noise from the Bowhouse skid. Another advantage is that the bulk of the weight is lower down and you can still use the original upper cover which is a few grams lighter, improving the CG, even if only in a small way, but every little bit helps. In the words of the immortal Smokey Yunick if you want to lighten your race care by 100 lbs the thing to do is look for 1600 places you can shave an ounce.

However, if I'm not mistaken (and someone please correct me if I am), the two ears sticking off of the mount is for one of the control arms, no? If that's the case, then I don't see how it would work with the N2R skid plate since it incorporates the tranny skid and the bottom portion of the motor mount into one unit. | |

| Re: Bowhouse N2R high clearance skid and setting gear mesh
BTW, I forgot to mention that I installed an STRC aluminum motor mount for the time being until the GRC mounts arrive. I also used the "B" mounting position per the manual for my gearing. The new mount fit into the N2R skid better than the stock plastic Traxxas mount. When I tightened the clamp I could see the motor was at a slightly different angle. Test running on the bench and on the floor went well with a reduction in noise from the first time I did this swap, although it' still a bit louder than stock. I won't get to take it to the course until Saturday to try it out but it seems very good now. |

This is my second go around with the Bowhouse skid. V1 was pure 3D printed garbage and I promptly sent it back. However, this new V2 skid is the real deal. Excellent fit and finish. I do however have the problem with gear mesh and noise. I just installed it yesterday and I think I know how I'm going to resolve the gear mesh matter and we'll see if that reduces the noise. I think it will.

Does it really make a solid difference offroad? Ive always wanted one but i also dont feel like its my skids that usually get hung up. Its usually the sliders, links or axles. | |

Following up, I was wrong about the gear mesh. After checking it, the mesh was actually perfect! We'll have to see if the noise changes with some run time break in. I've been looking at some 100 and 110 shocks in order to give your excellent shock upgrade a try! Last edited by JC3; 04-24-2020 at 10:26 AM. | |

Reading that the GRC mount had a gear mesh viewing port in it, I decided to make my own viewing port in a stock gear cover. I had a spare gear cover and trans to experiment with. I used a spare plug from the receiver box to seal the port up.
