Not really 2 cents. These are just the little things that make flying more enjoyable. Most of these are DIY's so cost is an estimate. And not all these mods are mine. Some you have seen before and some are just plain obvious Mod1. Cable Tied the gimbal plate. 2 cents. Notice it is NOT tight. Good replacement if you run out of Anti-Drop Pins and I think it works better in crashes. Mod2. Glued Lens cap and Gimbal Travel Lock together with velcro so I dont lose them easily. The velcro also sticks into my camera bag. Mod3. Backup USB charger that doubles as a Transmitter Stand. $10 AUD. Reaches both FPV Phone and WIFI extender for emergencies. Mod4. TK 102 GPS Tracker. $35AUD. Watch out for fakes. Mod5. Numbered and Directional Labelled Props. Makes them quicker to attach. Mod6. WingNut Sunshield. Easy to pack and quick to assemble. Mod7. Wing Nut Arm Extension to suit Larger Tablets. Mod8. Thumb screws for Prop Guards (under testing). Hopefully this will help quick changes. Mod9. Additional Box padding. If you have a case that you travel with, there is a chance the gimbal lock can fall out and a chance if knocked hard enough (thrown luggage), your camera can dismount from the gimbal. The padding will minimise movement in the case. Some accessories: Tripple Charger. $12AUD Slow but good for multiple batteries. Car 150W inverter. Use the exisiting house hold charger in your car. $20 AUD. DJI car charger is $120. I also use a booster/jumper pack (to start cars) and leave it in the ciggerette port charging while I fly First repair: Left Toggle Switch. $3.50 @ Jaycars. My bird was flying ATTI and HOME. I hope these are helpful.
