Here ya go...I carved out a couple of mm off each side...basically just trace the outline of the bigger battery. I use blue painters tape to help hold it in...it peels off easily, yet sticks fine for flight, and belly-landing.

Maybe a how-to on getting it to fit.

And how are you guys charging these batteries? As I have the Celectra charger, I doubt it would fit
Hope that helps...and the little white connector fits right in the charger. I glued a small strip of plastic to the connector and wires, so I could pull it out, and plug it in without risking loosening the connection between the plug and the wires.

cheers!

helps alot, thanks. just a couple more questions.

can you still use your landing gear?

and is the battery much "thicker" than stock?

And, is tape required to hold it in? As I see you still use the stock velcro, I have took that off mine and I have heavy duty velcro, would the velcro I have hold it in fine? (without tape)

looks like to me the red connector is pointless, why not just cut it off?

There is a small (tiny) amount of lube from the factory on the bushings.

OK, don't go getting scale on me. LOL I didn't want to use metal for the cross braces.


Metal on metal on metal needs a lubricant, You have a metal gearbox shaft that runs in bronze bushings. So a tiny and I mean tiny little bit of lite weight oil is a good thing for em. Yes you can apply too much and that will collect dirt.

As for the graphite trick, that's an old one from back in the Pine Wood Derby Days. If you were a Cub Scout you should know what I'm talking about.

Graphite is a dry lube. And a pencil lead is actually graphite based. Applying graphite to the plastic gears lubes them so they mesh more smoothly.

And yes it could be used to lube the slides on the servos, be a bit of a bugger to do so but it would work.

NOTE: DO NOT use it near an electrical connection. Graphite will interfere with electricity. Old school trick on someone you wanted to play a trick on was to pop off the distributor cap on their engine and run a pencil lead inside it. The graphite would play havoc inside and cause the engine to miss/ backfire/ and run very poorly.

OK found the fault in the tx. Some poor chap over in China musta sneezed as he was soldering the board. Right where the positive lead is soldered to the board, and I had to use a magnifying glass to see it, there is a whisker of solder that is touching the pad to the left of it on the board. It's so darn small I can't even get a photo that shows it clearly.

The second pad runs through the circuits to a tiny micro LED. And from the looks of it it's getting it's ground through a back feed on the other side of the circuit to the battery ground lead.

Should be an easy fix, but I'm going to wait to hear back from Horizon in case they want to see it.

*Yes, I flew the second half of the day with the gear on.

*The battery is maybe a mm thicker.

*I use the stock velcro to hol it in place so I can put tape on it. I don't know if your velcro would work...but if it's heavy duty, my guess is it will be fine.

*I believe the red connector is for a balance charger. I would assume you can cut it off, but I'm not cutting mine...I just stuff it back up in the fuselage.

If you aren't supposed to use graphite near an electrical connection, lubricating the slides wouldn't be advisable, since the slide is attached to brushes that run along resistive strips.

Since a 1 cell, "by definition", can't be balanced, the red connector must be an alternate. If you do cut it off, be careful not to short the leads (i.e., don't use metal wire cutters or an Xacto to cut both wires at one time..DUH) -- or your battery will quickly expire!

A nice stocking-stuffer (except that shipping takes a while...)

Why do you say "they weren't designed for lube"? Never heard that one.

Tri Flow has certainly seemed to help both my gearboxes and motors.

LOL...got me there! I'm leaving the other lead on as there doesn't seem to be a need to remove it. Also, I used to build custom car audio stuff...so am well aware at the bomb-defusing-like surgical cutting of wires.

Another hobby of mine is (downhill) mountain bikes...I use tri-flow on my gearboxes too.

LMAO...that's why I started using painter's tape...because the clear tape snatched all my paint off!
