If your heli do not have enough power….

Normally newbies never complains about this… try in order (first item are costing nothing, last solution is the most expensive):

• Adjust your pitch curves (too much ° pitch asked ?),
• Adjust your throttle curves,
• Add more nitromethan, try 15% then 30%, but be careful of the fuel price and lifetime of engine!
• Switch for an exhaust pipe, (Hatori…) +5 to +7% increase
• Use smaller blade, (505mm instead of 550 mm),
• Change for a better motor, (OS46 or OS50 instead of 30”size)

For more basics advices, search for FAQs on internet, a lot of documents has been already written…..
