I think I wanna go this route then try to solder on the main board.. A few question.. Do I go to radio shack a jus ask for a 2.2k ohms resistor 1/4 watt 5% tolerance? Do I jus pit the resistor in-between the yellow wire an the positive motor plug? And care to show a diagram with your expert art skill ![]() |

![]() I cut off 8mm from each SR120 tail blade tip so as to create enough space between the tail blades and main blades. The downwash on the mains would have caused issues with the SR120 tail blades had I not done this.
My first flight: Main blades had power. Flips, rolls, loops and inverted were MUCH easier since you no longer have to baby feather the collective. I heard very little if any bogging and I currently run my pitch travel adj at 85%. You still cannot stick bang but it’s a vast improvement over stock form. The SR120 tail mod however was disappointing. During pitch pumps it kicked out considerably and I had a piro flip that was only supposed to be a simple flip but the tail decided to spin on me. I am curious to see if the stock tail will do better but I have to think not since it’s a weaker motor with smaller disc area. I might also mention I was flying is winds that were much stronger than I would attempt in stock form.

![]() The problem with using the SR120 tail mod and the extended boom together is that the CG is way off and with a FBL heli that creates issues during piros and inverted hovers. You would literally have to tape the lipo on the nose of the heli to even out the weight distribution if using a SR120 tail mod on an extended boom. I have the esc and the Hyperion 240's mounted in the front and the with the stock boom length the CG is perfect. If I extend my boom out by 2cm (mod length) I would have to add dead weight to the canopy to re-balance the CG of the heli. I may try going back to a stock tail setup and see if that is any better, the same or worse.....then toy with the ideal of a BL tail.
After all this $$ invested in the mCPx…………it would have been cheaper to go with a stock Walkera FBL BL heli with TT or belt tail. Oh well, live and learn.

![]() No you won't damage anything, but you may get better more linear throttle response with the pull down resistor. Maybe Tnt can weigh in and tell us if he noticed a difference with or without the pull down resistor.
Good Luck, Don Quote:

![]() With my BL mCP X and the 300mah Turnigy 35C batteries mine is quite nose heavy. So the SR 120 tail mod may make a perfect combo

![]() Sorry if i missed it but what is the rtf weight of your bird.? If possible would you be able to weigh it also without your head and swash? This would be great info for those who would run stock head and swash.

![]() Curious what motor I should use and what everyone's opinion would be. I have my thesteve converter on the way should be here this week and I have 3 motor options as I have some extra one's laying around from my wakera's.
So, my choices are the WK-003 which is the same as the helimax motor TNT is using. Next up is the Red Turbo Ace model 91416 and then the HP07 or HP06v2 whichever you prefer to call it. Just wondering which one you guys would use if you had those 3 choices. |
