Hi,
TT expo 3D is it a good 3D model.If I fit a tt46pro will prop hang.

Its a great plane to fly. Yes, it will hang on a TT46, mine did and use an APC 11x5. It will have enough to pull out with authority. Only thing is that the CA hanges are rather sad ... get new ones please. She is very fun to fly.

pic,videos and opinions.

what are CA hanges ?keep posting!

Sorry ... CA HINGES ... its those white paper like bits that holds the aileron to the wings etc. Change to branded ones please ... it can come off.

how it does KE?

KE is not that great, need to mix ... well the F90 is also the same ... does not KE that well if its not mixed. The EXPO flies nice ... good inverted harriers too and is sooooo easy to hang. I love to putter about with mine, when it was still alive.
