I've been following this thread for a few weeks and finally decide to give this mod a try. I'm a little more comfortable taping the battery, so I started with TB47. I had no trouble following the instruction from the OP for adding add aux inputs.
My next decision was finding a mounting solution and decided on an arm mount. I used a Tarot TL80B04 for 25mm tube, which works very well.
For batteries, I decided to start with a pair of Zippy Compact 1800 mAh lipos. This is a bit conservative; however, with the TB47 I can hover for 20 minutes and land with 20% left in the TB47 and each Zippy 1800. This is about 5 minutes added to my TB47 standard hover times.
Next step is to mod the TB48's (or AC) and will probably go with a pair of 2650 or 2700 20c batteries, I've not decided which model, but the 20c 2650 weighs in about the same as the 1800 Zippy 40c, so I'm hoping for about 5 - 6 additional minutes.
None the less I am happy with the results so far. This is simply an easy mod and has a considerable performance enhancement with little to no side effects.
Thank you all for sharing your setup information.
