Default Batteries

I'm really stumped on what battery to use. I'm new to electrics and I read the everything you want to know tutorial. I plan on using the high max 46B combo here is the website http://www.maxxprod.com/mpi/mpi-264.htmland i just need some help choosing a battery. It's for a Kadet senior kit. I want a decent flight time and I need something simple. I'd like to utilize a BEC also so I'm sure that will affect my flight time. Suggestions and help please!!!

Well not really knowing the plane, but having a 60 sized plane that weighs in at about 8 pounds. This setup gives it almost unlimited vertical so it should pull the Kadet Sr. with ease.

Well, I use the BEC that is in the ESC. I am running 4 servos, and when I have it in glider tug setup it is 5 servos and have not had an issue so far.

I just used stand offs, threaded rod, blind nuts and nylok nuts to mount my motor. I used "PEX" tubing from Lowes. It is something like 5 feet long and is about $5.00


Here is a video of the plane in action.

Buzz, you have been more help than I could have possibly asked for. Could you do me a huuuuuge favor and give me the specs on all that hardware you used to make you motor mount? I really appreciate all the help you have cleard up a lot of the muddy water. I'm currently overseas with my unit(I'm in the Army) and as soon as i get back I'm going to get started working on this project. Thanks again man.

Also how do you center the electric motors? I'm a little fuzzy on this got any advice?

Well, you being over seas has been more help to me then I could ever give you in return!!!! Thank you for being there for all of us.


I used (4) 10-32 threaded rod 12 inches long. Blind nuts are (4) 10-32, (4) #10 fender washers, (8) 10-32 nylok nuts.

I needed for of the threaded rod because mine were just over 6 inches, so I could not get 2 out of each piece.


In the picture, the hole is to center the fuel tank. I just used that as a reference point. You can draw a center line vertically and horizontally to fine the center of the firewall and start there.

Post any questions you have and I will answer as best as I can. If not I know some one on here has the answer.

Buzz.

I have not had to program it. I plugged it in and away I went. Brother in law has the same one and it does the same, plug it in and go. I have, I guess 10 of that brand and never needed to program them. I am running them with 4s, 5s and 6s batteries and no problems.

Here is the simple approach, read the instructions for the motor. Hi-maxx provides excellent recommendations, including batteries.

If you click the link for the 46Bcombo you will get the instructions for the motor.

The combo 46A and 46Buse the same motor and prop, so you can use the same battery.


Hi-Maxx recommends (20-30C) 6S2P4960 as the battery pack to use.
