FPV Summit Project
« on: September 28, 2013, 11:58:11 PM »
After seeing some videos of first person view RC cars, I figured that's one of the last areas I haven't done with FPV that I'd be interested in.  I started reading the Tonka FPV Summit thread  (http://www.rcgroups.com/forums/showthread.php?t=1333642) on RCGroups and it pushed me over the edge.

A new Traxxas Summit costs $550-650 depending on where you get it.  After monitoring eBay for several weeks, I was able to score one for $320.  Its risky buying a used RC car on eBay because you never really know what you're going to get.  There are a lot of people that sell what they call 'Rollers'.. they look great, but they don't work.  The one that I bought had tires that wobbled a lot.  I found that the tires had water inside them and tried to empty them out.  Even after emptying them as best I could, they still wobbled so much they shook the car.  I tried to balance them with clay but had to use soo much clay.  In the end, I had to buy new tires for it and new lipos too.  The tires were ~$100 for 2 pairs and the lipos were about $40 from hobbypartz.  So.. in the end, I really only saved about $150.  Still, I'm lucky the transmission works perfectly.  You can lock the front and back differentials separately turning this into a full 4 wheel drive monster.

So, the next step is to buy a old Tonka pressed steel toy.  I've bid on several but always get outbid.  I'm not in a hurry though, this thing is a blast to drive.  It's not a speed demon; I think it tops out at 25mph with the motor it has in it.  It's built for rock crawling primarily and speed isn't what I want with FPV equipment on board.  Believe me, 25mph feels fast enough with this big 1/10 RC truck.  Each of these tires is larger than a can of soda.

Removed the OEM receiver and putting in the DragonLink receiver.


From what I found on the Internet:
channel 1 x 2 steering
channel 2 esc
channel 3 2 speed
channel 4 and 5 are the lockers.
I think factory setup it chn 4 is front and 5 is rear
..and I'm trying to figure out what the hell that means.  To RCGroups I go..  :dontknow

After getting the DragonLink RX set up, I was bound and determined to FPV this truck before the end of the day.  Instead of taking down the Christmas lights, I tinkered with the FPV Summit.   ::)   


The FPV gear on board is a GoPro 2 w/ 800MW 1.28Ghz Video TX/RX and I'm using a IBCrazy Pepperbox antenna at my base station.  I'm really happy with the pepperbox receiver.. it is both directional and omni directional meaning the video doesn't cut out if you go behind it.  In this clip, I go behind my brick house and behind a brick wall all of which is in the opposite direction the pepperbox is pointing.



Now that the mechanics are working.. I have to build the permanent body.

Progress..


Things are coming along  It takes more than I thought.  These Tonkas are built like tanks.  I've been through about 4 Metal Cut wheels but my dremel is holding on like a champ. The dremel is not the optimal tool, but I do with what I have.  I think I could get through life with my LiPo dremel, duct tape, and vice grips

you may want to check out the LED's from home depot. they are 3W and put out some nice light. they are $10 each but well worth it and they are 1/10 scale 7" lights :D they work much better than the stock lights.

This is COOL!  What OSD are you using? Are you adding that post processing?

I'm also looking for the $15 Vid TX that you mentioned on HobbyKing with the special frequency.  RMRC is sold out on the 1.3Ghz Vid RX's.  I noticed they have one with 4channels and one with 10 channels that starts at 900Mhz; they're both the same price.  Why would anyone go for the 4ch RX if there's a 10 ch RX for the same price?

Do you use a jig to make your antennas?

After a bunch of really annoying issues, I finally had a good almost hour long FPV session with the Summit.  I've shortened the video to 10min by speeding up the video and taking out the pauses where I was experimenting with different antennas at the base station.  Most of the video below is straight from the GoPro (HD), but I do flip from time to time to what I see through the FPV feed. I was impressed that I was still getting signal through 4 houses and non-line of site topography; it wasn't the best, but it was driveable.

I put a sound card in the Tonka Summit.  It will be able to interact with people better now.


Total cost of the sound system was $35.
