Added winglets and changed to an 8x6 prop on a 3000mah 7.4v lipo for main flight power. 1050mah 3s for video (will be changing out for a smaller, lighter solution soon). 900mhz 200mW video.
Very simple FPV wiring under the canopy.
I dont know just how the winglets are going to affect flight yet. Will soon find out.
Had to replace the canopy, so I molded a sheet of balsa to cover the guts
Really nice spot to stick one of trappy's custom stickers

dooooo it!!!!
I built a new antenna specifically for the frequency I am using. Its called an "Inverted Vee", which radiates a more uniform rf patern than the stock antenna. So far tests around the house are really good compared to the stock monopole antenna.
I am using an ebay 2826/6 motor. 2200kv and handles 342W. Im using a 8x6 apc prop with a 3000mah 7.4v battery. Draws 43A static WOT, and can go straight up no problem. Not quite unlimited vertical.
I used to run this on 11.1v with a 6x5.5 and it was great also.

Ok, I made a patch antenna for the video reciever, and I am impressed. It worked 1000% better over my stock dipole. Patch antenna is the only way to go. I had very solid video today, with very few glitches - even when banking hard at 750m out.
It was wildly windy today, and I couldnt get too close to the ridges, and wish I could have. But I did have a close encounter with a tree.
Also, I tried 2 flights today, one with and one without winglets to see how high wind affects it. I noticed with the winglets that the plane tracked a bit better than without, but both were equally as bumpy in the wind gusts. See if you can tell which landing did not have the winglets
yep 2nd landing was without winglets. When coming in for the landing, I like to flare off as much speed as possible before skidding to a stop. The wing dropped out from under the plane at stall speed, and I tumbled. No damage whatsoever, but still proved that the winglets help in guiding more air across the wings, preventing tip stall. (at least it proved it to me)
