I don't know that I'd put two packs in a 72 unless they're fairly small, due to weight. A 2s 2200 got about 5 flights (if my memory serves me correctly) and was down to 7.8-7.9 volts, so it probably could have gone 7 or 8 flights between charges.

New tail design on the 72" today... it's inspired take on the actual Extra Aircraft logos. (thanks to Santi8 for some creative assistance)

Just finished up my 3dhs 72 extra to day took it to the field to run it. to windy to maden thought used 93 octane gas 30:1 had to open low end about a quarter click runs great. the savox servos are awesome so far. I used the hitec graphics because I was going to go that route but went with gyros recommendation of the savox's

Got a chance to maiden my 72 extra 330sc last weekend. For some reason could not get the dle30 dialed in, and only flew it once. It came in a little nose heavy with the ignition batt mounted up front and a push/pull setup for the rudder. I will move my a123 pack back a little bit and that should fix it.

After tearing everything down to diagnose the engine problem, there was some evidence of the spinner backplate rubbing against the front of the cowl. How do you guys shim your motor out if you need to? I think a single flat washer between the standoff and the firewall would be enough. I've never performed this, so I thought I would ask your all's suggestion.

On a side note, the engine problem turned out to be that the supply line came loose inside the fuel tank
