My wife and I are in in the beginning stages of setting up two ground based FPV rigs. I will be running a Summit, and she will be running an electric converted 3.3 Revo Overall our goals is to be able to go and explore local parks and trails together, with ability to go behind objects as more of an importance than distance. Here's a glimpse of the parks we'll be in.
36982

Current Summit status/gear:1280Ghz800mw Vee-VTX & Homebuilt Biquad-VRX, FrSky DIY w/telemetry 2.4ghz in Turnigy 9x, Dewalt on stock ESC, gearbox tore open awaiting new bearings, basic DIY pan/tilt setup for RMRC 420VTL, custom aluminum 'shelf' for FPV gear.

Updates:

17 December 2013
Removed the sensored brushless setup, re-installed the Dewalt setup. Found two grenaded bearings in gearbox. Range check with Vee/Rubber duck, about 300ft clear video. Made very simple Pan/Tilt setup.

A little back-story for you guys with too much time on your hands:
Some people buy RC's brand new, I'm not one of those people. No- this Revo 3.3 was passed down through barters and trades thanks to the wonders of craigslist, and eventually ended up in the hands of none other than myself. Now, I traded knowing this Revo had some issues and I am prepared to do a complete tear down and rebuild to learn the car as well as fix any problems I may find along the way. One thing that is fairly neat though is this revo is converted from a nitro to electric. The grand plan though is to mount a mobius action cam on it and drive it in first person view as a crawler. I have been looking into some hard plastic or metal bodies from tonka toys and the like to create a semi-permanent mount for the FPV gear.

What's currently in the Revo 3.3?
✦ I'll be updating this shortly with a list of specs for you.

[12-6-2013] Found that there was a bent steel rocker arm post and replaced it.

[12-8-2013] Took apart the front differential, thought I found rust but it ended up
just being mud and caked on dirt. The person before me ran the revo pretty hard.
Cleaned the differential but didn't end up having to replace anything thankfully.

[12-19-2013] Extracted the stripped screw keeping me from
digging into the rear diff and discovered a spool inside.


[12-20-2013] Removed spool and rebuilt the rear differential.
Spool that was initially in it is shown on the right.

A few updates.


Summit: 1280Ghz800mw Vee-VTX & Rubber Duck-VRX
Did a dry run on the video gear craving some of that sweet video feed. Vtx sat perched inside about 3 ft off ground as Improvised and I ran out to the car about 150ft away. Plugged in the VRX and powered up that little Haier LCD as fast as we could. There it was, clear and crisp, a perfect video feed of our disaster of a hobby room. This was exactly the fix we needed to keep our minds off the flips flop footwear in winter as I start to drive to see how far we can go and still get the goods. Turns out 300ft is that distance right now. Overall want to push that number out an additional 700ft or so,the first thing that might help that is if I actually stood the antenna up on VTX and didn't have it pointed at almost 45 towards the ground...
37134

I removed the 2350KV Sensored Trackstar from the Summit along with the Mamba Max Pro to transplant them into Improvised's Revo. Shortly after that I figured out why my Summit was making angry noises at me, I had not only grenaded 2 bearings in the gearbox, but had also managed to embed the ball bearings into the plastic gears. I've never been afraid of peices of metal this small until they came hurtling out of the gears at seemingly supersonic speeds as I plucked them out with a jewelers screwdriver. Plucked I dont' feel does justice to what I was doing here, there was nothing graceful or gentle about it, those things wanted to stay where they were.

Project super simple Pan/tilt=Great success! Basically two servos hot glued to eachother at 90 apart, one twisting the assembly, and the other pushing on a very basic mount from an aluminum U bar with a bit of bent servo rod for the support and pushrod.
37133

Project mobile flood light is in full swing. I have a relay run from servo input that I will be wiring to a total of 21 LED's. Project DIY Spectrum analyzer is at a grinding halt due to me being at work till tomorrow. Hope to get that up and take a look into the areas we plan to drive and see how 900Mhz is doing. Considering trying to build a yagi at home, in part to see if I can successfully do this and also to try and improve penetration/directionality from the stock rubber duck.

See this guys? Don't do this. This is not cool.
If you can't solder, learn. If you don't want to learn, pay someone to do it for you.

I used to teardown my Summit by buying extra differentials, new, from eBay. Then I'd pop better bearings in the output shaft of each. Then during the teardown, I'd just swap the diffs out. Made the teardown go fast. Did same with tranny, although this is easier to get to. At my leisure, after Summit was back together, I'd overhaul the old diffs. However I stored a set of new diffs in a box for about a year, and the lube starting leaking out.

I can completely understand why you'd do that. Finally managed to get a screw extractor and remove the stripped screw. Turned out there was a spool, so I'm going to have to replace the rear diff seeing as how currently the diff is locked and I would rather it not be locked and get resistance from heavy differential fluid. A lot of the bearings are caked in mud and I'll likely replace a decent bit of them as well. I was considering cleaning them all but they're pretty bad I'm likely better off replacing them and if I need one later I can clean the old ones and use those again. I'm surprised they even spin to be honest. Haven't run into any destroyed bearings yet though, as I've torn apart pretty much everything at this point I don't think I missed any.

I grew up with my dad who was into airplanes and aerial video recording, he never actually flew it in FPV, but he would record videos of his flights and I would go with him a lot of the time. I think all I really needed was someone to get into the hobby with and now I have that, but I'm trying to do things myself and not just ask for help. There's a real sense of pride in that I think.

I felt good when I completely overhauled my Summit. Except in my wallet. This was before FPV, and I ran that thing through mud, sand, dirt, tall grass, snow, ice, I had it swimming (the tires will do a kind of dog paddle). I finally had the thing spinning in a circle on ice and literally exploded a diff bearing. An incredible amount of accumulated mud and grass was stuffed around the rear diff housing that wasn't visible from assembled vehicle.

There were more bearings than I thought there would be. On the Traxxas Summit forum there were two schools of thought on bearings: pry them apart and clean, reuse...or simply bag it and replace. Most opted for cleaning, but I studied bearings way back in college and knew that just a tiny bit of wear in a bearing race, one little pit...and the bearing is doomed. OTOH, to replace all bearings is $$, so whichever way you go, have fun, will be great to see what you folks come up with wrt FPV design.

What I'll likely wind up doing is replacing several, cleaning the rest, and saving the ones I replaced just in case I destroy one at some point. Because I am FPVing and not really looking for speed with the FPV, I think that whatever bearings I do end up reusing later should be ok at least for awhile, at least as backup.

Ever had any issues with rusted bearings or parts after running it in snow/ice/water?

My daughter is not on the forums but she does fpv, planes and Summit, she is in the videos I posted somewhere on here, in fact she has shown No in interest in RC until I handed her a pair of goggles.

My daughter is almost three and I already have her learning her left and right banks. Not forcing it of course, she just sees daddy doing it and wants a part. Can't wait to fly with her!

Oh yes, rusted bearings after snow, water, ice. I'm amazed the poor thing ran as long as it did before exploding the bearing. And that was after spinning high speed in a circle on ice (unlocked diffs) for about ten minutes. Most people think the Summit is immortal to water, they throw it into lakes, etc. But once you tear it down you see it is vulnerable like any machine. Only the electronics are somewhat waterproof, and you'll lose that when you start to mount FPV stuff on it.

Still, it is one tough machine. It lasts far longer to abuse than many other RC stuff. You can run it a long time with messed up parts, like bearings going bad. For FPV, I treat it very kindly these days.

Some people (me included) upgrade some of the bearings to shielded or sealed bearings, like Boca or Acer brand.

Yeah, a lot of people perceive the waterproof to mean it's perfectly fine pretending you're a boat, but things rust. It's water resistant, not completely water proof. The gear is only water resistant because it's placed in a case as well. As for the body, if it has scratches or nicks in the paint where you can see the untreated metal underneath, there's a very real possibility of rust. Bearings definitely have a huge issue with that too. I would still try running it in the snow though I think- as long as I didn't have FPV gear mounted on it or any electronics exposed. I haven't looked into the sealed bearings at all seeing as how at this point I have too much electronics that would be damaged either way and no solution to protect them- so that being the case sealed bearings would end up not being utilized to their full potential.

There was one time my boyfriend just really wanted to drive his Summit with the FPV gear despite the fact it was lightly raining and he threw a plastic bag over it. It did keep it protected from the light rain however the view on the monitor was terrible and it was hard to see anything, so not a good solution or one I'd recommend. Haha. Also not sure if it was due to the rain but the video signal was suffering a significant amount that day. I feel as though the weather may have played a role in that.

Good news: tore down and replaced bad bearings inside the gearbox, summit all put back together and ready to go.
Bad news: It appears I messed up somehow because now the summit is making a different set of angry noises at me now, time to tear it down again....
Fpv news: Have all the parts ordered to start building a few different antennas, currently looking to construct a couple biquads, we are pretty excited to get out hands on this sort of project, something new to both of us and there's a ton of pride to look back on your own creation improving your equipment.

Long awaited Updates! A bit of a delay due to life and our wedding and all that jazz.

Got around to building a Biquad. So far the video seems to be very clear from what little I have used it, but no range test done, and control signal cuts short before video.
42487

Also finished a few touch ups on the FPV rail. Had to adjust it some because of the new batteries. Used to run a bolt up through battery compartment, but now with the SPC 8200mah I don't have room. Heavy duty velcro it is. Though I do like my work on raising up the stock ESC a bit and keeping it more or less in the same spot.
4248542486

Wired up all the new LED's I wanted to install. Drilled out the holes to fit 5mm LED's, wiggled them in place, soldered up some parallel circuits and got giddy from all the light.
4248242483

And lastly, just finished removing the pinion off the new Dewalt motor to drop in. Also recently upgraded to a Savox 1230 for steering.
42484

Still want to clean up the wire mess I have on the summit. I don't even have VTX or camera wires in this mess and it all looks like chaos. Also the view from the camera has a whole lot of hood in it, want to rethink it's location a bit, along with the servo's for my pan/tilt died.

Cool cool cool. I love your guys' blogging abilities!

I've built a few revisions of an FPV summit. Ground FPV is a blast. Here's the last summit I built:

https://vimeo.com/13082536

I've got it rebuilt and waiting to test. I've kept as much of the "water resistance" as I could with this version, so hopefully going to be getting muddy soon. Cant wait to see your rigs in action!!!
