I've had the Venus finished for about 4 months now, but haven't taken it up yet. Been practicing and getting experience on my Sky Raider II first. Now that the weather is nicer, days longer etc. I just started the final adjustments on the Venus as well as breaking in the engine.

Getting the Venus to balance according to the manual, I need to add 5 oz of weight to the engine block!!
This seems like a lot. Is this normal? I already have the battery showed up as far as it goes under the tank. The engine I'm using is the Mangum 52-XLS.

How do I even fasten 5 ounzes of lead up front?

Thanks,
