Okay so here are a few pictures of what little I have done since last pictures. I installed the turbine battery in the bottom behind the fuel tank or just on the other side of the bottom bulkhead. I have the turbine in place and centered. I also placed the Jeti Pilot tube in the font nose. It was not bad to put in. I used a small aluminum tubing that I cut to size. I tapped both the tubing and the inside of the drilled hole. I then put Hysol on the threads and screwed it in. The Pilot tube slides freely inside the tubing. If need to be replaced I can take the front will off and replace. If the aluminum needs replacing then I can unscrew it and place another in. I am waiting on xicoy cg meter so I can balance it correctly. I made a battery holder for the front but will not fix it perm. to the airframe until I get the cg meter. Keith (FenderBean), after looking at the battery packs I think I am going to go with either the duralite 2s2p lithium ion's or the 2s3p ions. with self balancing.
