I just had too much on my plate…but I’m back.
I’ve been looking the best way to place the Brushless main motor on my frame and if you’ve been reading a bit, some spacers are needed to avoid the servo boards touching the main motor. At first I tried with the empty tube of a BIC pen..
but was so big so I decided to look for a smaller one..lollipops sticks, cotton ear cleaners (smaller) and finally I found the perfect source for spacers at 0$ cost… Wires !!! yes, we need a small gap of 0,6-0,7 mm between the servo pcb and the main motor so just take a piece of wire and peel it of, the plastic tube fits perfect.
After putting the spacers on the boards I put them back into the frame, the gap was ok, main motor not touching the pcb
Then is soldered the Dual ESC to the main board using the next diagram (Thanks Daryoon from Hacksmods blog)
You must use a very thin solder, mine its a Spike operated by 3 AA batt.
I’ve not pictures of the ESC attached to the main board, sorry but my camera ran out of battery …. 😦
I turned the transmitter on, put the battery (The heli was without blades to avoid any damage…) I heard the sweet music from the ESC… and voila everything working…but now the bads news 😦 😦 😦
After a whiles the motor stop, I was worried about the FETs so i checked ’em, FETs Ok so let’s try to spot the problem…..
The problem seems to be the main board, it can’t stand too much current drawing so if i put the tail motor off, everything works (I noticed a small delay the first time you push the throttle, I thinks it could be a kind of safety mechanism, next time the motor starts ok).
Conclusion, I feel sooo sad 😦 , I think HobbyKing Dual ESC it’s not a good choice, I’ll rather wait for the Air Base setup (only main motor) from Miracle Mart (currently out of stock) because I’ve read it works better and it’s smaller than HK Dual ESC…
