How do you make the cp do a flip without losing rpm and lossing altitude, i have tried it 2 time and lost like 10 ft altitude each time. Is there a secret? Or do you think its me, i did what i do on simulaters. Should i do loops wit it, or just a stand still roll? which is best, i have the brushless system in my cp pro, I have not tried to roll it yet, i need to set my radio up for stunt mode, im using jr7202. o plz help me?
