Have two of the older kit electrostreaks. One with Astro Cobalt 15 running on 10 cells (WOW is all I can say) and the other with 17 turn car motor running on 8 cells. This one flies well and long, but not as hot as the other. Also have 2 unbuilt kits. Have not tried the arf, but there is hardly any difference other than the fuse so it should be just as good and have heard that it is. Enjoy!
