Solved What size spinner for 8x6 3 blade propeller on cub s+

#5
It may affect the looks but it will not affect how it flys.
Hey man how are you? I have another one!
Im trying to put two batteries at the same time, one down in the hatch and the small on the receptor cabin on top, covered with the wing and its 4 screws. Can i put low V buzzers on each one? 3300 and 1300mAh;
Will the small one buzz first making me take off the wing to silence it or they wil come down at the same speed and buzz when all is over? If not what you recommend? I' putting them in parallel..

What do you think about that one

Would be a hassle?

I abandoned the prop idea, one day i'll get a Turbo Timber with lights, water rudders, 3 blade prop, no messy cutted dlaps, 4S and sturdier, more stable at wind, maybe more heavy but it seems its worth it, there may be nothing compared to this cub too

Doing well, thanks. How are things for you?

I would not recommend using those 2 batteries (3300 & 1300 mah) in parallel or in series. To use batteries in parallel, they need to be the same size, mah, C rating & cell count. They also need to be the same age, as batteries age the internal resistance increases. Power will come first from the battery with the lower internal resistance.

Nice man thanks.
And the battery with the less resistance is the bigger? So it will burn the bigger first?
3300 35C 1300 25C?

Hard to say for sure what could happen. but yes you could ruin a couple batteries. Fire is unlikely but it is possible.
Plus, I don’t think the 1300 will add much flight time.
