Just some food for thought...if you're looking for more survivable RC combat I would recommend the newer E-1000 class that is explained on the RCCA (RC combat association) website
Just limited to a 1000mAh battery pack. I've been flying a modified version of Mike Fredrik's Arrow from years ago that was designed originally for .061 glow engines you describe. Heath Bartell who writes the RC combat column for Model Aviation also sells a very good 3D printed kit for the E-1000 class as well (Search for HB1 RC combat)
E-1000 has been growing in popularity in my neck of the woods & the survivability of current designs along with the speed of the builds makes it fairly attractive. The innovation in designs has been fun to see through the years and the performance of these little planes is remarkable. I've been flying 4 of them for the past several years and finally toasted a wing that needs replacement at my last contest.
