Flying slowly is a great skill to master. As well as looking nice, it’s really helpful for starting young or inexperienced raptors. Flying slow is made easier by wind, as well as by ensuring the model isn’t carrying any extra weight. Wind means that the aircraft can fly slowly, and you can even hover on the spot in a gale.
Another way of helping the model to fly slower is by making it as tail heavy as you can get away with. This causes the nose to pitch up and the model can be flown slower almost at the point of stall. Be careful though, en excessively tail heavy model is very difficult to keep in the air.
The best way to move weight towards the tail is not to slide the battery all the way in. This takes weight away from the nose and shifts it further back in the air frame. You can use a small square of foam pushed into the battery slot to stop it sliding forwards.
You can also add weight at the base of the tail. The airbrake servo cover is secured with a small amount of hot glue. In this recess, you can add up to 30g of weight. We find that putting in one or two 2 pence coins, each weighing 7 grams, works perfectly, but anything can be used. Securely replace the black plastic cover, and go for a test fly. You can add and remove weight to your liking.
Be careful, due to the nature of Rocrow use, each model soon becomes individual, so spend some time tinkering about and getting to know it.
