Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

As I haven't built a new quad to add to my collection for a while I've decided to build another micro quad but I have a choice of motor kv a choice of frame size which then gives me a choice of prop size  :banghead:
So these are the fixed definates I'm using a 1104 motor and a 3s lipo....... now the choices :-
1. The motor comes either as a 4500 or 7000 kv
2. The frame is either 95 or 113mm wheelbase
3. The 95mm frame will take a 1940 Gemfan hulkie prop whereas the 113mm frame will a hulkie 2040 prop
So what's the best combination I'm thinking the 7000kv motor as I'm only running 3s but smaller frame smaller prop or larger frame larger prop ?
The centre of both frames are the same size by the way so you haven't got more or less space to work cramming the fc,vtx and rx in  ;)

Don’t know if you’re still looking into this but I would take the 7000kv motor. I run the 4000kv 1106 emax on 4s with the gemfan hulkie 2040 or the hq 2 inch prop.

For frame size, that’s up to you but I’m surprised the 95mm version won’t take the 2 inch prop.
