Looks fantastic Edgar! I was running with 240 grams of weight in the tail cone extension where you haver some weight in the picture. Over time the wood in that rear former started to crack where I had the key way cut to hold it on. I've shifted the batteries back now to remove the weight and used carbon plate on the woodwork to strengthen it if I decide to stick any weight back there again. Just a heads up if you do put some weight back there
Cheers,
Andrew.
