  "POP QUIZ CONTEST"
Posted by: JimmyLe813 - 11 hours ago - Forum: Community Fund Raise and Giveaways - Replies (1)

OK everyone, I hope you have your thinking caps on. Next month will be a year since I got started in this great hobby. And I have recently been informed that INTOFPV.COM will be turning 1 also. This forum has helped me improve and learn so much. So I got together with the moderators of the forum and came up with this contest to help me give away a 3" starter kit. It is part of a 3" quad that I hardly used, less than an hour of flight time, and I'm no longer in need of. 

It has:
Diatone ET Frame
Piko BLX Flight Controller with a custom TPU Mount
4 DYS XM20A ESCs
4 EMAX RS1306 Red Bottom Motors







And as the title of the post says this contest will consist of a short quiz. of 12 multiple choice questions. One for every month INTOFPV has been online. (Thank You Oscar for helping me come up with the questions).


Rules of the contest are:
Member must have a minimum of 20 post
Only 1 entry per member
Entry must be in by January 28th before 12 Midnight Pacific Standard Time (I will be going off the time stamp of the PM, so the best bet would be to get your answers in before the 28th.)

In the event of a tie there will be a tie breaker question which will be posted on 29th for all the qualified members.

Please send your answers to me in a Private Message. I will post the answers, along with everyone's totals on the 29th.

Before I post the questions. Here's a little hint: correct answers can be found by searching the forum.

And please send me your answers in this format:

1. a
2. b
3. c
4. d

It will help make it easier for me to check your answers. Thank you and Good Luck

  Best ESC for Dshot?
Posted by: cche - Yesterday, 12:53 PM - Forum: Motor, ESC and Prop - Replies (5)

I'm partial to Aikon SEFM 30A. I've had great luck with them. However, I want to move along to Dshot and rather not have to modify them. What's the best BLHeli_S ESC right now for DShot? Also, what's the difference between the Aikon SEFM V1 and V2?

  Check for Shorted brushless motor winding
Posted by: OverDischarged - Yesterday, 12:48 PM - Forum: Motor, ESC and Prop - Replies (5)

Can anyone tell me how to check for a shorted or broken winding in a brushless motor. I crashed and have a stuttering motor now and want to be sure it's a motor issue before I replace the ESC

  Best FC for DShot
Posted by: cche - Yesterday, 12:46 PM - Forum: Flight Controller - Replies (4)

What current FCs are the best for Dshot. I have a couple of X-Racers, Motolab Tempest and Cyclones, RMRC Dodos and of course KISS FCs. But I'm talking more Betaflight for my Aikon ESC's.

My FC seems to struggle a bit with D-shot, even on Multishoot, post Betaflight 3.0 I only run 8K/4K on all rigs. 
With 2.9.1 it used to be able to run like 8K/8K/32K, but no more with the new firmware.

  Putting LiPo at storage charge

When do you guys put lipos to storage charge? Normally, cheaper chargers can't discharge quickly enough. What's your practices ?

  Syma x8hg Headless mode understanding
Posted by: bumpie - 01-19-2017, 10:58 PM - Forum: Beginner Questions - No Replies

Already lost one. Got a new one today and dont want to lose it. Trying to understand headless mode. The User Manual sounds like all headless mode does is to define a new "front" for the drone.  It was my understanding that in headless
 mode, no matter which direction the drone was facing, that pulling back on the "forward / reverse " lever would make the drone return to the controler. Pushing forward on that lever would make the drone go away from the controller no matter direction the drone is facing. It does not seem to be reacting as I thought it should but has simply defined a new front direction for the drone. What is it supposed to do in headless mode? Sorry for all the dumb questions I am asking.
