This is an effective simple battery holder I have been making for the T-28 for many years.

The idea is to keep the battery from moving fore and aft after balancing.

I have rehabbed about 2 dozen T-28s. All need something. Many times a PO has done something that makes it impossible to secure the battery unless a mount like this is used.

Look at the pictures. This mount is always a Tee, but needs fitting or altering depending on the plane in for repairs.

I make the Tee out of wide tongue depressors, or maybe Popsicle sticks. (we have a box of craft sticks from Walmart.

I get the Velcro from Walmart.

I 5 minute expoxy the Tee pieces but hot melt glue it in place, as I find that most effective.

This post is to give you ideas.

This setup works well for me.....

I do not like planes that do not have ailerons.

The Easy Star I got had the beginnings of flaperons when I got it.

I dug deep into my RC hardware box for control horns and what not that would work.

I got to use my Z bend pliers too!

The servos are held in place with a few dabs of hot glue on the edges.

They are covered by some blue dollar store "duct" tape (ha ha stuff is too thin...but good for model planes.....)

I have programmed my trusty DX9 to have spoilers and flaps in addition to the aileron function. You have to love computer radios!

Flight tests coming soon......

FYI: NEVER do this sort of stuff with out a decent servo tester. It REALLY helped getting the basic setup right from the start.

Change of plans.

I had intended to use 10mm x 0.5mm but that would not work due to the curve of the wing.

I used 3mm x 1mm instead, just like I used on my Sonic 185

I had to remind myself to use a NEW blade EVERY TIME you cut foam!

NOTE you have to cut the groove deeper to allow for the curve of the wing, too.....

I used Goop to fix the rods because it remains rubbery flexible and holds well unlike some ARFs where the rods fall out!

My Easy Star has flaperons added.

Experience tells me the wing has been weakened.

Here is my start to adding an extra carbon fiber spar

I am done with the repair and new motor mount!

I used mainly white transparent Gorilla Glue to hold the mount and to fill in voids.

It IS solid now!

I am refurbing an abused Easy Star I picked up. Knowing that the brushed motors are not that good, I decided to go brushless as part of my rehab.

A 1/2 inch ABS sprinkler line coupler is the exact same diameter as the 400 brushed motor. I used a cheap hole saw to cut some surplus scrap plastic I got for $1 per pound at eplastics.com (Ridout here in San Diego.) I epoxied it to a line plug. The coupler and plug are Home Depot purchases.

NOTE Do not forget to rough up the two parts before gluing them so the adhesive has something to grab oun to.

This mount costs less than $2.

I love to recycle things like this and the motor is a 28-36 1800 kv 438 watt motor swinging a 6x4 prop at 183 watts. These parts are from my large stash of parts I have been accumulating......hee hee....
