Bought a second hand Xray T4 '13, got several shorty lipo's sitting around from off road, I know I will have to add some weight to balance but how do you secure a shorty on chassis? Do you have to drill more holes?

Yes to weights to balance left and right sides. Use strapping tape to secure battery.

So just put the shorty in one of the L mounts (front or rear?) and just use tape to hold it in place, won't it move around too easily?

I used a piece of hard foam to make up make up the difference in size, but didn't really have a chance to get the balance right. The battery stayed in place just fine.

I tried using shorty batteries in a TC5. I first moved the esc to the right side of the chassis and used some weights to keep the battery from moving forward or backwards.

Does any body sell a scale that we can use for set-up problems like this?I'm trying to set up a 10L just for fun.So far,all I have is stick packs to use for testing.I'm getting real bad brodys to the left.I'm hoping to buy some saddle packs soon but still working out some other problems such as gearing,got some on order.

I bought the SkyRC Corner weight system.....works great. It looks the same as the Gforce. I haven't tried it on my 10 pan car yet.

Your shorty looks nice, but most tracks have a minimum weight for touring cars. Most are around 1350-1450 grams. You will need to add a lot of weight to get it up the legal race weight.

The Gforce scales are real nice. X-Ray simple balance pins work well for left to right balance.

Shorty pack touring is probably a dead end in most cases. The weight requirement for ROAR or IFMAR is pretty high, and even if you're running club racing with a 200 gram light car and it gives you a measurable advantage someone will probably whine.

Offroad gear is a better arena for running smaller packs because it lets you make weight when running the heavier, stiffer, and much more durable aluminum chassis, super-chunky suspension arms, big bore shocks. Back when we were running associated B4's and such gear some years ago guys running 350 gram packs were commonplace to gain power and get weight forward in the car. Not a problem with the new gear, so they're putting more emphasis on chassis and packaging instead of maxing battery performance.

I ran and still have my Losi Type R which runs great with a shorty pack in its somewhat unique mid-chassis battery tray design, but the battery tray I run is made of STEEL, not aluminum, to add 120 grams and it was still a few grams under the 1380 minimum despite the 2.75mm carbon chassis components, full size metal gear servo, no-motor-limit ESC, fans, and all the rest.

Because of the weight requirement I think touring car design will continue to be full-size pack. Maybe saddle or split, but still full size.
