I had my LT40 all put together and went to balance it, and was nose heavy. So, I decided to move the batt and rx aft and that will balance the plane, but how should I secure them in place? Before I moved them they were in that space under the fuel tank and fit nice and snug. I've attached some pics so you can see what I mean.

You can just use some hard wood sticks, like pop sickle sticks, to secure the components. I tend to build a small frame along the sides of the fuselage and add a hatch.
One thing, if you can, place the battery in front of the reciever. In a crash, the battery could crush the reciever.
Some people use little eyelets and rubber bands. Or you can just use foam and maybe wire ties to secure the components to the belly. It really depends on what materials you have handy.

Make sure you clean up those wires, if you leave them like the ones in the picture above your sure to tangle them in the servos causing major problems.[:@]

Have fun, Dave Trimmer

Use Velcro.

I agree with MinnFlyer. I use velcro for holding that stuff down. You can go to walmart, go to the sewing section, and they have all kinds of the stuff there. I usually this NON sticky back stuff, you can get like 3/4" yard of it for like $1. Then CA it to where it needs to go. You can also run it going with the fuse, just play with it to see where it will work best.

thanks for the velcro idea guys! I think that'll work great. And yeah, dave the wires wont be left like that. The crappy thing is, I have to move my switch from where I first mounted it cause the wires wont reach now, and I'll be left with a hole in the fuse.

You can use a small piece of monokote to cover up the hole left from moving your switch. Nobody will know it was ever there after you cover the hole up

Hope this helps

yeah that would work Ken. I think i'll just leave it for now though. its not a very big hole, and its under the wing, so If the wing is on its not very visible

Leave the switch where it is and just lengthen the wires, unless you don't like to solder or don't know how.

yeah i could do that as well

If you don't know how to solder very well I would not suggest messing with the switch. Too many planes have been lost due to a faulty switch. One thing I would suggest though is to apply a little epoxy where the wires go into the switch. This will reduce the risk of the wires getting loose and pulled out.

Coolbean,
Not a good idea. If the epoxy creeps into the switch it can get onto the contacts and cause the switch to fail. If you want to secure the wire it's better to use a zip tie around the switch and the wire so that it's secure and can't pull out.

Hope this helps

Good tip Ken, Thanks!

if you leave the hole, make sure fuel oil exhaust won't get in their and screw up the balsa.

You can put a piece of tape over the hole to close it up. Clear packing tape is a good thing to have in your flight box anyway because it's very handy to fix holes in your covering. It can save a flying day.

Hope this helps

the switch is on the opposite side of the plane from the exhaust so that shouldnt be a problem. Even so, I think I'll just solder some extensions into the wires to make them longer instead of moving the switch.

You could put a sticker over the hole. Like futaba or other radio sticker or one from a doller store

hey thats a good idea too. My OS engine came with some stickers....

You could also use an aileron extension from the switch to the rec. or batt. or both. ENJOY !!! RED
