Is it possible to use the same motor for 425 and 550?

snowflakes · 06-25-2010, 05:46 AM

Just yesterday got my hands on a gaui 425 kit.
Now I'm taking the time to find out what electronics to put in.

In the future I want to extend the 425 to a 550, So I'am wondering if there is a motor-setup which can be used for flying 425 first, and lateron for 550.

Looking at the motors used for a 550 they are about 1000Kv
--> Can I use this (with different gearing/pinion) to get enough headspead for a 425?

Hoping some of you guys has some experience with this.

I set my 550 up as a 425 for a while using my Z20A 980kV - it flew OK, but probbaly not up to 3D (but neither am I

). If you went for a 1100Kv motor with a 16 / 42 / 20 / 61 gearing that should get yopu up to about 3,000 HS. Then stick on 14 / 60 /20 61 and you are back down at 1,800 HS.

I got a good deal on a scorpion 3026 1000kv and tried it my 425, it was good enough for sport flying (which is all I can do) but didn't have any power for punch outs.

oh yeah, so what need lower KV? 900 or not sure what all they make.
did you play with the gearing or know what HS you was at

I was running somewhere between 2500-2600 for head speed.
