Guys all i have to say is WOW
. I ran the engine for an hour tonight
at 2500 going to full throttle at 15 minute intervals. The engine started as soon as i figured how to get fuel to the carb and idled after finding out the trim was to low. it hit 7000 by 30 and by the time the hour was up it was at 7150. I do have one quetion. I have two reciever switchs but tonight only had one 2000 hydramax battery installed. at the end of one hour that battery was drained. this is not what i expected. i have hitec 985s coreless( my first coreless servos) do they drain more power or was the vibrations causing that much drain on the servos. Let me say that still have the throttle spring hooked up. i just don't believe that it would draw that much juice.
Skillet92, are you peak-charging your battery? I am using a 1400mAh NiMh (6.0V) DuraTrax for the Rx and a HydraMax 2000mAh 4.8V NiMh for the ignition. I get four flights (45 - 50 min?) before I even begin to worry about re charge, but I check the Voltage before each flight and after four flights, I usually peak-charge again. I'm using 9151 digital servos on ail. and elev. and Hobbico CS-170 on the rudder. I would think you could get five or six flights before worrying (although, you should always "worry" about your batteries and check the Voltage before each flight).
