I was asked for some pics recently for a little mod I was doing, and since I have a few of these handy mods I'm starting this thread to showcase all my projects related to my E-revo and to dispense some tips and tricks Please be aware these are only my tips, there is much information available on these forums from people far more knowledgeable than me, this is just information I've picked up which I'd like to share. If you're new here you should start with the FAQ.
This is not going to be an all alu super creation, it will simply be a showcase of nifty little mods and ideas of mine towards creating a better basher. A basher should be durable, reliable and dependable, but equally it should be cheap and easy to repair, so that's what i'm aiming for. Hope you like it.
Since project logs must contain pics, here is a picture of mine when it was new:
To start with I have to explain a little background. I live in the UK and imported my E-revo when they came out. I was one of the first people here to get one I believe so I've had it since mid summer. I have never had a 1/8th scale electric truck before however I have been into electric R/C for a while. I have had my fair share of problems, it's part of the game, but some of it has been less fun than I would have liked. So here are some Tips for New E-revo owners:
-This truck may say RTR on the box, but don't be fooled. Maintenance is mandatory, and there are a number of problems that your truck may develop if you don't perform the following maintenance before your first run.
1: Check the steering servos. Many need to be aligned. Failure to do this will result in decreased steering performance and reduce servo life.
To determine if they need to be aligned, turn on the truck, preferably upside down, and wiggle the steering wheel until the servos are silent. If you cannot make them silent, they need adjusting. To adjust them, remove the servo horn from one servo and adjust the turnbuckle until the horn fits onto the servo without needing to be forced. It doesn't matter if one turnbuckle is shorter than the other as the steering travel is not limited by the servos.
2: Re-glue your tyres. This is much easier to do before you use them. The factory tyres can come off during hard cornering if you use the truck on road. Simply reinforce the factory glue by running a bead of glue around the edge where the tyre meets the wheel, front and back on all four wheels.
3: Check the gearbox screws. These are located underneath the chassis, they need to be very tight otherwise the gearbox can come loose.
These are just the problems I had, but I could have saved myself hours by knowing about them before running. Cleaning tyre edges is not fun.
And finally, break in your motors. The best way to do this is simply avoid high throttle starts for several runs. Many people have motor problems, but I broke mine in and so far so good. Since the problems with them seem to be related to the brushes, I definitely recommend this.
And now a word on batteries.
I have talked about my battery problems at length elsewhere, so here I just want to tell you what happened to me in the hope that you can avoid the same problems.
My E-revo spent 3 months off the road because all my NiMH batteries were destroyed. I am not certain why this happened, but in my opinion the gearing in the E-revo is too high for most NiMH batteries. I lost $200 worth of batteries, and it wasn't much fun. So if you intend to use NiMH batteries, I recommend you undergear by at least one pinion size.
Since i now use LiPOs i know there is nothing wrong with my truck, so there are three possible reasons why this happened.
1- The truck is over-geared from the factory.
2- My truck has higher than intended current draw due to a different batch of motors.
3- My batteries were not adequate.
Neither of those possibilities are my fault and none of them could have been avoided by me. The first two because that's the way it was from the factory, and number 3 because I bought expensive batteries from well respected brands, if it was the batteries there was no way I could have known.
I do not want anybody having to put up with 3 months of Revo withdrawal like I did, if you run NiMH batteries please watch temperatures carefully. If they are too high run in training mode until you can fix the problem. It might save you a lot of money.
If you have not yet purchased your batteries, I strongly recommend you purchase LiPO batteries. The performance difference is huge and they are worth every penny. I wish I had used them from the beginning. 2 Lipos is better than 6 NiMH batteries in my view, even of the same capacity. And my 2 LiPOs are way better than my 6 dead and dying NiMH bateries.
Ok, that's the boring bit out the way, my next post will contain mostly pictures
