Build log Great Planes Viper 500
Hi all, I plane on doing an e conversion of the great planes viper 500. I need to know of a good motor inrunner or outrunner to swing no bigger than a 10 inch prop. specs of the plane are 52 inch wing and 500 square inches. Weight will be around 3-3.5 pounds hopefully I can get it lighter. I wan to build somthing to pylon race with shhhhh. I want to hit aroung 100-120 mph shhhh will want to go 150-180. I need a reccomendation for a 4 cell set up to keep it light. I need a motor that is capable of producing 700-1,000 watts and high rpm.
Thanks in advance for any help. Joe |

update
Hi all,
I brought the viper kit home today first impressions were the kit in general was well packed and had generouse hardware. The only thing I didn't like about the kit is thw wing is very heavy. I need to get a new battery for my scale. but it feels like it weighs at least a pound. I have started assembly and I am useing a Hitec hs 225 mg for ailerons and a futaba 3102 mg high torque for the elevator. waiting for the motor and lipo. if everything comes in I will get to maiden this beauty next weekend. |

Would a power 46 and 4s 4200mAh work?

Viper off shelf and on bench! Supplied wheels replaced (thanks PylonDave!) Should be a fun plane if given enough oompah. Great idea Joe.

Pylon Dave what wheels should I use? Dave you will get a chance to fly this plane. wings west wait two weeks I am working with Rich from Vision Hobbies to get an outrunner that will spin a 9/9 apc pylon prop at 20k or better. More pictures next week. Bab I might have to fly out there after I finish this thing so we can race or find time after the shoot out to race. Very nice chatting with you and look forward to using the battery.
