Happymodel Mobula7 1s HD with Runcam Split3-Lite camera feels heavy.
Potential solutions:
a) more blades
b) smaller battery
Results:
a) more blades test
Three bladed propellers: GEMFAN 1608
With three blade propellers there was a bit more thrust but at the cost of more noticeable prop wash outs.
Four bladed propellers: GEMFAN 1636
With four bladed props there was no further noticeable increase in the thrust, but the prop wash out was very bad and easy to provoke.
Original two bladed propellers: GEMFAN 1610
Thrust was the lowest, but also prop wash outs were the most difficult to provoke. Original propellers felt the best.
b) trying a different battery
I used to fly GNB 720mAh 100c batteries. They weight ~16g.
This time I tried DOGCOM 100c 450mAh that weight 13~14g.
The difference was very noticeable. With 450 batteries the drone felt a lot more nimble and a lot faster. I doubt that it is because of the weigh difference, I believe these 450mAh batteries have more true 100c rating than the 720mAh ones, as the C rating is not regulated. Because I don't think the ~2.5g of the weight difference could affect the performance so much alone. What do you think?

Antenna tests on googles:
Googles used Eachine EV800D
Patch antenna broken so I only tested the original mushroom one with 5dBi gain.
Versus TRUERC ODINE 5.8 - RHCP 1.5dBic
-The test. Flying around a brick house. Using full 400mW VTX.
1. Original Eachine mushroom antenna was ok, not perfect. I would rate it 5/10. Min RSSI DBM was -91.
2. TrueRC ODINE. I would rate the performance 7/10. Min RSSI DBM was -89.
3. Using both antennas with diversity. I would give 6/10. Min RSSI DMB was -90. Surprisingly worse than just a single TrueRC antenna. Why??

Antenna test on the drone.
Original vs TBS TRIUMPH PRO 1.6dbic.
Using single TrueRC antenna on the googles.
1. Original 7/10. Min RSSI DBM -89.
2. TBS I would rate 3/10. Min RSSI DBM was surprisingly good at -87. The problem must be somewhere else I guess. What could be the problem? Mismatch in the optimal frequencies?
