Having said all that / this is my favorite T45 / Hawk model. The weight gives it a scale like feel and mine is relatively fast as I installed the inrunner motor with 12 blade EDF upgrade way back. It does draw some amps but it’s worth it IMO.

Got to maiden my jet this last Sunday evening, wow this thing tracked very well like if it had a gyro. Gave it 2 minutes for the first flight on a 5500 Lipo. Track well in landing configuration, but I landed in the grass next to the runway. It pulled all 3 gear out, including part of the top of a wing.
Now I need 3 new gear servos. Looking forward to exploring this jets fast side, and aerobatics. |

I'm only new in this thread so please excuse if I have missed something.
From the pages that I have read, it seems like this plane looks awesome, flies well but it is using the same battery as you would use in a 80 mm EDF like an Avanti. On my Freewing Avanti, I set my timer at 4:30 with a 6200 6S. From what I read on this thread, it seems this aircraft is much heavier and has a lot more drag and most people seem to be setting their timer at only 2:30. As much as I love the look of this plane, I can't justify spending that much money for 150 second flight times. Am I right in saying this is to be a big problem with 90 mm jets? Is there a solution to give say 4:30 minute flights? Has anybody experimented with higher capacity 6S batteries? Would this plane carry the extra weight? Considering the fact that this plane is quite a lot bigger and heavier than the Avanti, you would think that it should carry a larger capacity battery? I noticed several people have put in high voltage setups but their battery capacity in Watts has been no greater in fact 2 x 4400 4S is less Watts (130) than 1 x 6s 6200 (138). One big difference with 8s versus 6s of course is the lower amps however I am more after flight time than flying WOT. I would love to buy this plane but really want longer flight times without turning the thing into an overweight nightmare. |

With a little throttle management, I am getting 3 minute flights on 5000 6s batteries.
I have never experienced the wing waggle or any instability at lower speeds except once or twice on approach where it was going really slow (too slow) Mine takes off nicely off pavement with no flaps at all, but I usually use half flaps. I flew mine for a long time with the LE flaps disabled and it seemed to make nearly zero difference in handling. It is groovier with speed, to be sure, but I would not call it unstable at lower speeds. |

I.e. any EDF battery combination that does not make the plane too heavy. I appreciate throttle management is an absolute must and I alway use a lot of throttle management when I fly. |

Minimum 4m30s flight times?
You don't want EDFs (at least not this T-45), you want prop planes |

I've never heard of anyone having more than 4 minutes of flight time without low-voltage cut-off and/or puffing the battery. |

As for straining the airframe, that all depends on the maneuvers / g forces you ask it to do. Flying scale aerobatics (less than 5g) should not overload it. There becomes a point though where any aircraft becomes a pig if the wing loading gets too high and that is my question. Has anybody tested the plane with a higher capacity / heavier battery? |
