I'm getting ready to put together a Tiporare in classic format (pipe & trike retracts) and am considering what radio equipment to use. I will be using a Futuba 10C 2.4G radio and am looking at servos. I am considering using the Hitec HS 5245 MG digital mini servos for the control surfaces (1 for each aileron). They have [email protected]/[email protected]/in. Given that back in the day we used standard servos with only about 50 oz/in, would these Hitec be adequate and a good choice? I'm considering a Hitec HS 5065MG (micro) for the throttle, do you think this would be a good choice? On a somewhat unrelated topic, would you build your flight system around 4.8v or 6v battery packs?

Final question is on retracts, what is the current thinking of retracts for this type of plane? Air or servo based? If servo based, what would be recommended? My last tipo in the 80s was about 8lbs so I assume with the newer radio equipment a modern day one could be built lighter?
