Default Re: Balance 86 Yak

Mark,

Are you using a Carbon Prop? CF prop is about 2 oz heavier than wood.
If you have your battery on the engine box, you are a little nose heavy. Don't worry about what the balancer shows you, fly it! You can remove the weight but leave it for your first flight.

Thank you,
Reza

So moved 4300durallite side of motor box and have added a combined total of 160grams of stick on weights to front top and bottom of motor box, balances at 190 fine. This seems like a lot of weight and wondering if anyone else fitting carbon spinner had the same. I imagine an alloy spinner would weigh a lot also. Balanced on an EZ Balancer but the balancer seems exceptionally good, same when i balanced on fingers just easier with balancer.

A tru turn 4"spinner weighs 5.8oz which is 168 grams, so with both batteries in the motor box and the spinner id of thought i should be slightly nose heavy.

Any feedback very welcome as i want to maiden this week.
