Default EVA sport, what motor/electronics to use?

For those of you who have built and flown the EVA sport please tell me what setups you went with. I have checked the forum and found a few threads with some info but not a complete list of what would work together well. You know what motor, gear box (if using one) prop size, esc, battery pack (what discharge rate) servos, bec (if used) etc. I'm going to order these parts soon and there's a bunch of different ways to go and it just gets confusing to me. Thanks in advance.

What was I thinking?

Hi If at all possible, Stay Away From Gearboxes and use a direct drive brushless motor on Everything, except giant size Planes A 400 size motor will work Great with your plane with the 41" Wing span, Hope that helps, Chellie

http://www.headsuphobby.com/Power-Up...otor-E-545.htm

And if you're after maximum thrust and a long flight time, the GWS EP9050 prop and a 11.1v 1500 30C Lipo battery will give you excellent results.

Dont Worry about Watts when Starting out, use oz of Thrust, its much much Easier, the 9x5 prop and a 1500mah 3 cell lipo will give you about 30 oz of thrust, more than enough for your plane.


Battery Size ***** Propeller Size ********* Thrust (oz.) ******* Amps
3-cell 11.1v, ***** GWS 9050 Prop,******** 30 oz. of thrust **** @ 15 amps

use the tower pro or HXT 9 gram servos, Tell Jeff at Heads Up Rc That Chellie sent you

http://www.headsuphobby.com/Towerpro...rque-D-135.htm


use a UBEC for cheap Insurance when using a 2.4 Radio system to prevent a possible brown out condition.

Thanks for the info Chellie. I saw what MM suggested on their site. I also wanted to see what others had used as well. I guess it all depends on how you want to fly. I haven't flown in awhile so I'm not going wildcat right out of the gates!!

What was I thinking?

12Oz without battery? That's light. a 400 sized motor would work well as chellie pointed out. i am ahuge fan of jeff and headsuprc. i have bought over 10 motors/esc's and generally gets from florida to utah in 2 days for $2 shipping.

your in good hands

slow stock prop reversal. it flies! easily! 543 watt dual motor bipe slow stick. push-me-pull-you. 242 watt 3 channel slow stick. 365 watt mini ultra stick. 415 watt mini contender. 810 watt ultra stick .25e. 220 watt alpha 450 sport (retired).

Yes 12ozs. is very light. I have read of an AUW for this plane of 20 ozs. ready to fly. Thanks to both of you for the "heads up" on HU r/c. I will seriously consider buying my gear from them. I like the way they explain things on their site.

Well my building is going to have to wait a little while. I managed to cut a chunk of the top and back of my thumb off chopping up potatoes for dinner tonight. I can't believe I did something so dumb. We have a new set of cutco cutlery and believe me they're very sharp. I was looking forward to working on my EVA.

Chellie is spot on. Any of the brushless 400 sized motors would work nicely. This is the one in my EVA and it's plenty of power with a GWS 9050 prop.

http://headsuphobby.com/Firepower-40...otor-E-630.htm

It's also from HeadsUp, but it's the Firepower motor.

Mine has HXT-900 servos in it, but any of the 9 gm type servos will work. I have had good luck with the E-Max analog servos. but I only have the previous version.

http://headsuphobby.com/Emax-8g-ES08...ervo-B-545.htm

ESCs... The one in mine is no longer available, but I've come to like the SkyPower ESCs that HeadsUp carries. They have actual Switch mode BECs...

http://headsuphobby.com/Sky-Power-20...-BEC-H-406.htm

And if you ever have any questions, Jeff and the crew at HeadsUp respond to emails really quickly.

Steve

Growing the fleet!
