Hi guys,
I'm working on my first electric airplane and I just made a quick video of it and wanted to show it and see what you think and leme know if you have any suggestions

This is my Hyperion Super Chipmunk 70E. It's almost completed and I wanted to get a video out before the maiden flight. It's powered by a PJS 3D 3000 motor and it will be swinging a 14X8 prop
I am using 2 4S 14.8V 3000mAh 35C lipo batteries that I will run in parallel to get 6000mAh from which should give me good run times. The motor will be connected to a 80 amp Brushless ESC and I will be using a Spektrum DX6i transmitter and Spektrum AR500 Receiver.

Cheers,
Chris

Chris ... she isa lovely plane, I just dorked mine recently and gave it away since I wanted to clear my hangar. Just watch the canopy, mine always comes off in a knife edge. Also, if you can, use 2 HS225s or HS85MGs on the elevators. The stock elevator push rod needs to be bent and that makes it flexible, not that it will cause problems when flying but if I were to do it again, it would be with 2 HS85s I guess.

I am not very familiar with your motor but for a 4S set up it seems a little low on the KV for a 14x8. I think she may need to be pushed to a 16x10 on 4S. Check with a watt meter if you can pull about 50A-55A at the very least.Mine was running with a DualSky 4260-577 KVmotor on 5S and a 14x7E prop.

I think the Chippi is one of the most beautiful looking plane in the air.

Chris,
Nice chipmunk, I have a smaller worldmodels chipmunk.... well I'm on my second one They are an awesome plane in the air.... nice profile and easy to keep orientated.

I lost my first one after an elevator pulled free during a flat spin, I had a secondhand one that I had brought for spares so 16 hours later I was back in the air.

Please post feedback or a video after your maiden,

All the best,
