you want your voltage regulator on the other side of your cutoff switch.. ie not between your charge port and your battery.

if you use that bat share are you charging both batteries at the same time?

check out the life packs at valuehobby.com. Im using one of those for my ignition and a 2s lipo for my rx. my ignition will take a 2s life unregulated. so I wont have any regulators at all and I get to have lots of voltage for speedy servos

Checking CG

I'm trying to finish up my build with still needing to setup/connect the throttle linkage, plum the fuel lines and install the fuel tank, hook up the spark switch, mount the ignition module, install the rx and ignition batteries and install the Rx. I had a question about checking the CG. I know that the ignition module and ignition battery will be mounted on the left and right side of the motor box just behind the engine. I have a good idea where I'm going mount everything else but should I be checking the CG as I'm installing the remaining components? Also when I do check the CG once everything is in it's place, does the furl tank need to be full or empty? Thanks!

what I learned from the guy that mentored me into the Gas Aerobatic Airframe scene... put the gas tank all the way back to the wing tube or if at all possible, centered under the wing tube. Fill the tank and then position batteries and regulators to achieve the desired balance.

With the fuel tank close to the wing tube, you'll feel less of an impact in the flight characteristics of the airframe as fuel is burned.

More Traffic/post!

We need more traffic in this 71 Slick gas thread! I've been building my 71 slick but the build manual is lacking. The key points that need to be addressed IMHO is the throttle servo setup/placement, linkage based on the motor selection. I started off using the DLE30 rear carb engine but switched to the OS GT33 based on the feedback from Joe Smith and father. Now this transitioned to the need for a different spinner adapter and what will work with the OS GT33. I've just got through this and know what will work with the OS GT33 having the right stand-offs to get the right gap with the cowl. I'll post my setup in a few days if not within the next few weeks. I check the 3DHS 71 Slick electric thread but the gas stuff is hard to sift through to find the right information you need for the questions you have on the setup for the 71" Slick gas. Lets stick to this thread for the 71" Slick Gas for information needed for the build/setup. Just my opinion. Thanks!

I agree 100%. My build hasn't had much progress in the last week or so but we just got a bunch of stuff in the brown truck to finish it off. Expecting one more delivery... the TME Pro Smoke Oil Pump http://www3.towerhobbies.com/cgi-bin...&I=LXAZRJ&P=ML
