Default Xtra 30 vs Xtra 30 EVO

A couple of weeks ago I unfortunately watched the pattern contest in Lindsay, I say unfortunately as after a 30 + year retirement from pattern flying I have decided to have another go. I now have two builders kits for the Genisis and am looking for a suitable power source. The Extra 30-10 EVO seems to be the motor of choice but $515 times two is a bit much, Icare have the Xtra 30-10 on sale for $275. Any advice as to what motor to use would be greatly appreciated.
Thanks
Philip Soden

Hi Philip

For Masters and FAI the 30-10Evo will be a better choice, for Sportsman through Advanced the regular 30-10 will do nicely.

Also with the regular 30-10 you can get away with using the 32.55ka controller (if you go the schulze route) so there is additional cost savings, with the 30-10 evo you pretty much need the 32.80ka.

The motors are almost dimensionally identical (the evo is about 1mm longer), so swapping out at a later time is an easy possibility.

Chad,
Thanks for the quick reply. I assume based on what you said that the Evo has more power and therefore needs the higher capacity controller. I just looked at the schulze esc on the Icare site, they mention "proportional braking", am I correct in thinking that throttle is set up so that you go from full throttle down to zero power and then to proportional brake ?. Thing were much simpler in the 70s.

Hi Phil

The Evo has a lot more power handling ability the the regular motor. You can use the small controller with the Evo but you need to be much more careful about cooling and other variables. With the 80A controller it is a much safer system with the Evo.

The "A" version controllers have the aerobatic brake on them. They are proportional if you setup your throttle that way. Essentially at a certain point in the throttle travel (which you can adjust with sub-trims/throttle curves etc.) the motor will start braking, and the further you pull the stick the more brake you have. Personally I set up my airplane with a low idle, and have a switch which lowers the throttle curve and gives me maximum brake which I use for only certain manuvers.

Hope that at least starts to explain it
