4" Arms for your ToothPick 3 to make it a TP4! 9x9 M2 mount motor pads still.
Pair with a 4" Prop
These were made by really popular request however we feel these kinda defeat the purpose of the TP3. Eventually we'll have a dedicated TP4 product just because so many people requested it but the original design was intended to be used as a 3" so the mechanics of the frame changes a bit but it should work out well. This would be a pretty darn unique flyer...
