Who makes the 530 fuselage? (Century, Thunder Tiger, Smartmodel, etc)? Is it a 30 or 50 size fuselage? Also, what mechanics are you running in the fuselage?

i would say its the tt fuz

engines
irvine 36 & 39
tt 39
os32 & 37
webra 32/35/36
toki 40

the webra 36 and os 37 will give the most power
the irvine 36/39 and os 32 will give a good power output

the tt 39 will be ok but it will run hot and the carbs can be tricky to get perfect
the toki 40 is unknown to me
if it was mine i'd go os32 or irvine 36/9

but remember it will fly in a scale manner ok
trying to hotdog it won't work with a 30

if you want more performance then it has to be a 50 class motor

Md 530 made by TT,there is a Raptor in it,tt 39 always run way to hot,not to sure if a 32 would be powerful enough.

you don't need to worry about the tt 39 runing hot they all do it
just listen to the engine and you will hear it when its running right

run the bottom end on the ritch side and tune the high for power
it will sound like a bag of nails on tick over

the one i had was abused (and i mean abused, run-in/out flat open with little pitch testing a new fuel to see if i could blow the motor up)for 30 gallons until i left it to late to change the rear bearing
the bearing broke up and took the piston/liner out
i fitted a used irvine 36 into the heli

the os 32 will power it for scale flying
the 37 has a lot more power but the rear bearing is an arm and a leg if it fails

i am running a hirobo lama 30 on an os32 and that is a heavy beast (its the one that ate all the pies and more) and it flies fine

I'd run a Webra 36. Higher compression motor, runs on lower nitro and they put out great power. I used to run a Webra motor in my Ergo 30. It performed well.

Thanx i would go an os 32 rather than a tt39,i have a n os 37 but need to replace the rear bearing which i do every 6 months,but the price £30.00,more than triple the price of the Hyper so thats why i need to change,but saying that the 32 would be the less powerful than any other
