Hi

I need a little help from you guys, Kiwi's superXtra (old style) is on overhaul right now!!!! a little history fist....... 2 servos per elevator and and ZDZ 160 w/regular muffler in front= tail heavy !!!!.

To get the a decent CG for Imac sequence we had to put 4 lb on the engine dome, then if you want to fly 3D another 1/2 lb on the tail wheel and the wing in forward position. We tested it for about 20 flights, Sequence are perfect but 3D, even with the lead on the tailwheel, is terrible.

So we removed all the lead and the CG it's now 150 mm back on the wingtip with the wings on backward position (IMAC). Now sequence are suck and 3D is much better.

Any of you guys who have one of this SuperXtra can give us some info about CG and specially engine/wings/elevator incidences ??
