How to - 12s T-Rex 600 Setup On A Budget.

[meatbob]

Thank you. Looking forward to hear the results.

Yes - 80% throttle at mid stick (simple v-curve in idle up) gives me just 2000 RPM - I just checked.

Cool thanks.

mine comes in at 8.24lbs/ 3737 grams. was curious how it compared to others. weather its heavy, lighter, or average. this includes 2 3000 40c flightmax's

Mine comes in at 3810grams same batterys as yours.
Headspeed is 2050 95% flat with the 12t.

Would I get away with XT60 connectors on this 12 cell set up? I'm going to be using 3300mah lipos: http://www.hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=9503

[tonyblade]

Tony, that's what I'm using on mine and they are spot on mate! I've got over 60 flights now and they are better than deans for me, xt60 all the way. Tony.:thumbup:

With apologies for butting into this thread, can anyone point me to a link to upgrade the main gear on the 12sT600e.

I saw earlier in this thread a recommendation to use the T700 Mod 1 170T main gear.

Can I use the the stock T600 hub with this or is there a conversion kit?

Thanks for your help.

[GB ian]

Actually I need even more info now, I was going to run the stock T600 main gear but having seen recommendations to upgrade to the T700 main gear I need someone to tell me which T700 main gear is recommended.

I will be running 12s on the 4023-630 with 12T...

Thanks

Will the Mikado 12T pinion work with the T700 Mod 1 gear....now I am totally confused!!

You'll be needing the KDE upgrade hub to use a T700 gear on your 600.

However, I have never stripped the stock 600 main gear in approximately 350 flights on 12T.

hello all , hope you all enjoying your 12s rex`s , i used a KDE hub n rex700 main gear in mine but went back to standard to see if i could break it , i use a 4025-630 on a 13T pinion , a 100% flat curve and the only bit that breaks is the TT drive at the front , and thats only on hard piro stops , cos my 401 doesn`t have an adjustment to soften the centre return , so in my opinion standard is fine as long as the mesh is good , it`ll last fine :thumbup:

[GB ian]

Thanks for the advice guys. I'll stick with stock main Mod0.7 12T Pinion for now, save a few $.

Had half a dozen flights out of my 12s 600 now, what can I say, I love this thing now! Power to burn! No more motor bogging.:lol::lol:
Thanks to rceccelston and everyone else that has contibuted to this thread, without you guys I would not be sporting this huge grin!:lol::lol:
Just running fixed end points 95% flat and 12 degrees pitch.

Well done. :thumbup:

[Tony Brazao]

I'm using the same 4025 630 motor as prescribed by the thread starter with the same esc & bec.

I'm thinking the 13t would be nice as I could increase the throttle curve slightly (go over 80%) to boost performance (at the cost of flight times) if the mood takes me.

I will more than likely be happy with a 12t pinion, however, if I ran a 13t pinion and set my throttle curve to 80% flat in idle up, would this still give me comparable flight times to 12t pinion at 100% flat?

Are there any other advantages/disadvantages/risks etc?

[caralmar]

I run the 4025-630 with 2 x 3000mAh 35C Turnigy packs. I fly hard for 6min and set my throttle at 100% flat. I use the Mikado 13T pinion. Head speed is about 2300RPM at the start of flight and about 2050 when I land. All 6 min are HANG ON!!!!

I put 2300 mAh back into each pack and they come down warm and at around 3.75v / cell.

Hey, awesome canopy!!!!

:D

Here's my 12s beast!

Ha ha there must have been a sale on these canopies. Lets be sure never to fly together. :rolling

LMAO! I think our 450 canopies are almost identical too!

Caralmar,

I laways thought that running 2300 was too fast on my 600N, how come it seems to be OK on the 600e?

This is just an honest request for clarification, I have seen this before and wonder if you can clarify...becuase if 2300 is OK then my 600N will be zipping around even better this weekend!

Well, I have now 65 flights on the 12s 600 ESP and have yet to find anything wrong with running that headspeed. She's fast, nimble, and an extreme powerhouse! With a 12T pinion, I found her a bit sluggish... but as soon as I put that 13T pinion on that motor, she came to life!

To be exact, I tached it several times at 2280 - 2300 RPM at 100% throttle in a hover. I can do tic tocs, full collective loops, and all sorts of collective abuse and she just keeps on going...no bogging!

Just make sure your mesh is nice and tight. I can move the main gear about a hair each way before it contacts the pinion. I've tried all sorts of abuse on the heli and the packs always come down just warm, and at 3.72-3.78v / cell. I hit TH right at 6min and put 2380 - 2420mAH back into each pack, so I use the full 80% capacity of the pack. I fly at 100% flat throttle for about 90% of the flight.

EDIT: Forgot a couple more things... go with Radix blades or similarly good quality blades, 30C or better packs to hold the voltage (I'm running Turnigy 3000mAH 35C packs), and fly for only 3min in the beginning until you have an exact burn rate per min for your packs. Once you have that figure, then simple math tells you exactly how much time you can fly and not go over 80% of the pack's capacity. In my case, the math worked out to 6min for my style of flying.

Hope this helps!

Those orange canopys are real easy to see!
Thanks for the heads up with the 13t pinion caralmar. I have one there and may have to give it a crack on the weekend.
Are the radix blades that much better than the align blades?

"Better" is a pretty subjective term. I've flown both and prefer the Radix blades. They auto very nicely and sound great. The key for me was quality... take any pair of Radix blades and throw them on the balancer... dead on, right out of the box! The blades look brand new, even after 65 flights... I just clean off the dead bugs every once in a while.. :D

[SkinWalk3r]

I have a pair of the preferred Turnigy batts on the way. I also have a pair of 5000 mah on hand from when I was just flying 6s. Now aprt from the obvious cg issue what other negative side effects would I see from using these just for flying around . No 3d.

Too heavy for good flight characteristics? Horrendous CoG probs?

I am running 12s setup with ICE 80HV, 3 Futaba 9252 was using V Bar with CC BEC pro. Plugged batteries in the other day and at low throttle without touching the transmitter the motor started to pulsate, The speed control burst into flames and all the servos including tr servo, receiver and CC BEC pro now shot. Any similar experience or ideas. My "budget" setup just became very expensive. Probably had about 30 flights on this setup with no issues. Thanks
