Hey guys, i forgot to mention, the recent hack kits sent out was sent with a little sticky thing with the headers, this is so you can cut a small slice off it, put it on the bottom of the header, and stick it to the board so you don't have use hot glue or something...i'd recommend plugging your 4 pin cable into the header before soldering, so you know its level with the board

I will likely test the ESC with the 3PM-x so I can see if that is working. Too many unknown variables at this point.

Question, the dig (ch3 trim button), can you lock it to +100% & -100%? It sorta seems you can by pressing the switch in, seems inconsistent though. I really don't want to hold it to either end.

OK, likely a M2 dig issue. I put the GT3B in my dual FX-R Bully (had to reverse channel 2 & 3) and it worked right off. So, 1st run it works well although I may change the mixing steps to 10 from 20.

I am using the dual-ESC as posted before, the buttons work well, may try the locked dig to see how that is compared to the momentary.

I will also try it on the M2 again to see if reversed channels help.

I got my radio to work and I love it!
Although I'm still trying to figure out if i can set the steering mix like my old Lansu radio. The Lansu had the crab/ 4ws/front only/rear only. I also ordered a flysky 8ch receiver and I will be setting it up with dual esc dig and a few custom suspension functions.

crab has to be on its own switch

[707offroad]

right now the little chrome thumb button just switches from crab to 4ws.... Maybe I missed something in the directions?

I can't recall what the settings were...

I'm on to new modifications. The stock rx that came with my Exceed Maxstone 1/8 is a 4ch 2.4hz and I just got 2 esc's. I Installed the 6ch firmware but I cannot get the radio and receiver to bind. Do you know off hand if this 4ch receiver is compatible? Also, how should I wire the second esc? Can I run dual batteries separately to each esc or should the dual batteries be wired parallel to the esc on ch2?

Lol should have mentioned i have a losi comp crawler so am i right in thinking its tranny dig???


Ch1 steering
Ch2 throttle
Ch3 need dig
Ch4 need 4ws / crab

Ok so crab and 4ws is one channel but will be assigned to different buttons i guess?

Thanks in advance

I want 2 batteries to increase runtime. Currently running a Turnigy 7.4 LiPo 5000 milliamp 2s 25-30c and I get about 7 minutes runtime. Also want to run BEC to increase power to servos.

5000mah and 7 minutes...in what?

Direct 2s is far more power than a bec can give you

CH3 trim: Dig tranny

Long Click REV
scroll to 3, enter
scroll to CH3, enter
scroll to NOL, enter
scroll to 100, long enter
go to the epoint menu, set ch 3 epoints to 0% both left and right (turn steering wheel to change)

Activate 4WS mix

Long click E.Point
scroll to 4, enter
scroll to CH4, long enter

D/R: 4ws mix

Long click REV
scroll to d, enter
scroll to 4WS, enter
scroll to NOL, enter
scroll to 100, long enter

CH 3 Button: Crab

Long click REV
scroll to c, enter
scroll to 4ws, enter
scroll to swi for non momentary, or mom for momentary...long enter

Your done...now set your epoints for the dig slowly. When your in the epoint menu it will turn the servo to full, limited throw, move the steering wheel to switch direction of throw



^^^i went off my brain, i think its all accurate though, report back to confirm or deny it working^^^

you have an issue elsewhere, i run a 13.5t brushless in my losi with a lead foot and i get 5-10 minutes off a pack (1300mah) there's no way 2 45t can out draw a 13.5t brushless. I run the same pack i ran mith my dual 35t broods in my moa losi, never puffed or got the packs warm, i run that 13.5t, i have to watch my packs, they'll get nice and warm and then ballon if i run em too hard

that 5000mah battery should run 2 45t's for at least 30 hard minutes.
