Velcro FTW. I like to glue some to the fuse and wrap around the battery too. Keeps the battery from shifting when I have dorky landings.

Reid,
I'm sure the clevis will work. I use the ball links because they're easier to remove. You may have to shorten the coupler to get the over all length of the coupler/clevis assembly to match up with the set up shown in the picture. The distance from the servo horn to the pushrod sleeve guide is fixed and critical.
Just run some tests, you'll find the right prop.
As regards securing the battery.... DON"T DORK THE KAPPA!!!
With the 707 and a TP 1300 mAh battery and a Thunderbird 54 ESC, if you position the servo tray so the forward edge of the tray is 8 3/8" from the front of the firewall you will be able to slip the battery into the fuselage, tuck in the wires and everything will stay put without any further effort. The battery will be out of sight up inside the fuse and the pressure from the wires ( which you may have to shorten) will keep the battery from sliding backwards. No room for Velcro! After you set it up, you will see that there is no way the battery will get away.

Jim

Thanks Jim,
I'm taking special note of what guys like you, Lenny and others are saying. I've always worked my way up to having nice TD/J and DLG models but not this time. I want my first 5J model to be top line competitive but that comes at the risk of expensive mistakes so I appreciate what you guys are posting.

I'm sorry you injured your Kappa. Seriously, is there anything worse than crashing a beautiful model (from a hobby standpoint)? I get dizzy, the ocean roars in my head and I hear Pavarotti singing Pagliachi, The Tragic Clown.....and I don't even like opera.

For holding batteries in place, use 3M Dual lock, much stronger than velcro

Is there a drawback in this? I've done this on all my TD and J models.

Also, I'm a little concerned about the varying Kv's in the Neu motors. For $250.00 a pop, one would think the output would be consistent in these motors; hopefully, it will be OK.

One last dumb question since I'm new to ALES/F5J (TD, J and K previously). What is the Best Practice way to secure the battery in the fuse?

Thanks, Reid

It's an adhesive backed, re-closable, snap-lock plastic strip, sort of like a heavy duty version of Velcro.

You can probably find it in most office supply and hardware stores.
