Status: online 		To all those of you who are running a DZ, the foam clunk that comes with the engine -- are you guys using anthing else to keep the clunk at the bottom of the tank. I was thinking of may'be using a fuel fuel filter somewhere close to the clunk to help it stay submerged. Your comments would be appreciated and I am sure helpful.

Thanks

The foam clunk swells up to about 2X size and gets soaked in fuel...This keeps the weight enough to not be an issue.

You can actually run a std clunk....the only issue is when the tank gets about 1/2 way doing high G stuff the clunk could pick up an air bubble and the engine will surge. As it stands with the foam clunk you can run down to about 1-2ozs left in the tank before a high G pull will casue the motor to suck that air bubble up....The motor will surge a bit and this will let you know its time to get ready to land.....I flew today and ran the tank nearly dry every time....I'm getting between 12 1/2 and 14 mins of flight time depending on what stuf I'm practicing.
