@stewe12, yeah that would be nice, especially the lag. Can be bit of a motor killer when you pull up too late and hit the wall in fast mode, no prop guards and no luck! I feel like the lag is less without the prop guards but I'm sure that's a placebo, haha.
@xcrost, I'm still testing the differences. I reakon without a wifi repeater the antenna mod does improve range but alas more testing is needed to be sure. The motors might be a little fast once you change out all four stock motors for the racerstar ones. Although I'm not 100% sure as a single racerstar motor works well with the other stock 3 motors as well. This to me says they are of similar specs, unless the tello is compensating for it and running that single motor at a different speed to the others when hovering.
I got some cheap scales and it clocks in at 75g. Dunno how accurate the scales are though. The stock tello (with prop guards) comes in at 91g.
Here's a comparison photo, the modded tello looks faster, lol...
The 'lil tello racer has gone through a few changes.
Carbon fiber frame conversion
2 x external 8dbi antennas
Racerstar 8250 motors
OEM midnight blue props
FPV camera "angle" mod
External battery mod
Lots of fun this little thing is. I promised it the next week will be all about the flight time and no "bench work" per 'se.
Here's a small (crappy backyard) video demonstrating the setup. I'm quite happy about the antennas in particular. The video quality is a lot better and I didn't experience any frame dropping which surprised me. The video is screen captured but the last 30 seconds is the video feed from the tello.
