Going to the dark side. Jammin X1 CRT Conversion.

[Thirdgen89GTA]

The Emperor's Force Lightning is strong with me now.

Jeff (Jhautz), if you are still browsing these boards, it only took me 4 years to get away from the juice. Perhaps I will see you at the Friday night Kohls hangout with a crazy beast of a Hyper One Seven. I've already stripped it of all nitro parts to "motivate" myself.

Much thanks to those who answered my other questions in different threads. You have saved me both money, and time. And though I went slightly different than most (dual packs instead of a single) I am very happy with the balance of the truck. I need to weigh each corner individually but the truck has only gained about 1.2 to 1.9lbs based on the weight of the components I've taken out, and then the weight of the components I've added back in. I was concerned that the stock 13mm shocks I had couldn't take the weight addition. Plus they kept blowing out. The new 16mm big bores have a much better sealing setup, and they will perform better too.

I still have to solder the leads on to the batteries and ESC, however my 60w soldering iron failed, no longer gets hot. It was a cheaper radio shack one anyways, I should invest in a good station. I may also buy an external BEC to take the load off the ESC, as well as pickup the fan for the motor itself to help it stay cooler if its needed.

Jammin X1 CRT Pro

• Mamba Max Monster + 2200kv
• (2) Gens Ace 40C 5000mah 3S Lipo (The Stupidity batteries in series, also endurance basher batteries in parallel).
• (2) Gens Ace 40C 5000mah 2S Lipo (for the track)
• RCM Mount + Servo plate
• (2) RCM 150x50mm trays/straps

Now for the fun stuff!

Nitro Parts Weight list

• 370g - Novarossi 528XR Hot-Modded by Jim Hots (still F.A.F engine)
• 120g - Jammin JP-2 Hard coated pipe
• 60g - Hitec throttle servo
• 30g - Fuel tank, tubing.
• Total = 580g

Electric Parts Weight list

• 442g - (2) 3S gens ace 40c 5000mah lipos
• 288g - alt bats. (2) 2S gens ace 40c 5000mah lipos
• 425g - 2200kv motor
• 125g - MMM ESC
• Total= 1,126g - 1,434g

Subtract the nitro parts and I get between 1.2lbs and 1.9lbs added depending on which battery setup I use. With the 2S packs its still slightly tail heavy but its very close to 50/50, wish I had a 4 corner scale to measure the weight of the truck but they'd look at me funny at work if I brought the truck in and started weighing things!

One thing I noted is that i should have ordered a custom 140mm tray for the motor side battery tray. It was too long. So I had to cut the tray. But since I had concerns about the motor sliding forward into the pinion I cut up an A-arm holder for the jammin and screwed it into the mounts to keep the battery from sliding forward. I may still see if I can pick up some plastic blocks or something and drill it so its a little taller than the one currently in the car now. But it works and I'll have to make sure to keep the straps tight. But I won't be doing anything crazy with it for the moment.

since i reversed the center diff and I have the massive 62t spur I had to clearance the chassis. Since all I had was a hand held dremel and no vice or clamp to hold the chassis it became someone of a messy job. I plan to do the X2 conversion later on which will give me a slightly longer chassis, as well as the smaller differential so it won't be nessesary to clearance the chassis i don't think. I couldn't use spacers due to the fact that the X1 diff is already so tall the CVD angle is rather extreme with spacers. I wouldn't trust that they'd hold, no binding but they'd wear out really fast.

I need to buy some rigid CF 2mm or so and put trays both in front and behind the center diff. I plan to run a receiver box on the back between two battery packs on a tray, and in front of the tray (where the RCM servo tray is) I'm putting the ESC there once it extends forward enough so that I can mount it to the steering brace. For the moment the recv. is mounted on top of the servo. But easy splashes there.

So I guess thats enough of the talking, here are the pics.
