rclement...

Good your flying that thing.

On the tank issue...Gjeffers asked the same thing a long time ago. He said the stock tank was 9 ozs. I told him he could get an 11oz from Horizon Hobby (hanger 9) and it was a good fit with no modifications. He said great and ordered it. When he got it he fill them both with fuel and they held the same amount. So with Hanger 9...9ozs = 11ozs. He did feel better though because it said he was carrying more fuel.

My answer is there isn't another tank that will go in that small area that is larger than the stock one.

You could shorten your flight times by one minute. That would help. Mine is very nearly out of fuel at 11-12 minutes. But I can fly that long each time.

Thanks
