1/4 scale extra e-powered


Here's some pics of the progress on my extra. Motor and esc is mounted, now all that is left to complete is the $100 hobbycity battery order that i keep putting off
After that i have to mount the cowl, put the prop on, and she is ready to go. I'm thinking i will have to put the lipo pack tied onto the motor mount or firewall somehow because she is really tail heavy...

UPDATE: I did the maiden flight this afternoon! That Assan HV-80 ESC had a hard time starting and running the motor, and eventually burned up, making a huge mess inside the cowling So, i ordered a Turnigy Sentillon 100A HV ESC and now it runs the motor sooo smooth. The programming card also made things much easier too.
Anyways, the power is just insane. At full throttle that 22X8 gas prop screams for its life The 2 flights lasted around 5 or 6 minutes each, not including a couple of short "hops" to get a feel for the trim. everything stayed barely warm, including the battery. The plane will go vertical from takeoff, and hover at 1/2 throttle.

I was so focused on flying i forgot to get my Sister to take some flying photos. Ah well, next time i will, i promise.

Here's the components i ended up putting into the plane:

Motor: Exceed Rc MonsterPower 160 $50
ESC: Turnigy Sentillon 100A HV $100
Battery: 2X 5000mah 5S 20C Flightmax (wired in series). $78

So, for $228 i have a 50-cc equivalent electric power system that is good for a 10 minute flight with no mess to clean up, and a awesome supercharged engine sound. Big electrics are the future.

Did another flight at the AZ Watts UP fly-in last weekend.
Many thanks to tom83 for the flight photos!!

Are you using pull-pull on the rudder? Moving that servo forward can affect the CG a lot..

not using pull-pull but i'm thinking i really should. Either way, i will have to go with 5000mah 5S instead of 4000 5S for sure.
Do you know of a good cheap pull-pull system?
