it would be really nice if those of us who pre-ordered the Gripen could also pre-order the TV so we could install it during the initial assembly.

Originally posted by xviper View PostI'm the same. May as well go full gusto and get the TV packed inside the same box as the plane. I'd rather not glue the stock tail on and then carve it up to swap rear ends. Is it possible to even pre-order the Gripen and the TV end at the same time? If not, I'll wait for the TV piece to be available before ordering the plane. It's going to be a winter project anyway.
I'm going turbine in my Gripen, and seriously considering going for the first ever (as far as I know) foamie turbine conversion to feature VT lolFreewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion

I assume you are talking about a RC turbine? Depends on the throttle setting - I've seen people walk behind a jet at idle power and during taxi. Spinning up and full power is a different story.

I didn't say I was going to let the foam direct the flow, now did I? :D
Just like in the main body, there will need to be spacers and a metal thrust tube - in this case slightly larger diameter than the fixed version, to ensure thrust being pushed through it and not spill past it.Freewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion

And Justin, and most likely Alpha. Was hoping one of them would chime in. I heard James mention that he was mostly flying on 4000s and wanted to know what kind of times he was getting.
For example, but Avanti usually has between 3:30 and 4:30 useful throttle time, mixed flight. My personal best was set just the other day, doing 9:57 airborne time, landing with 3.77 on the cells. The point being: Huuuuuge span depending on how you fly and what conditions apply.Freewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion

Not because they are not valid as such, but because even tiny differences in setup, conditions, temperature, elevation, and pilot flight style can make HUGE differences in the times you achieve on exactly the same battery.

I am also aware of this, but I am looking for a ballpark figure. Thank you, though
I used to love going large batteries in every model I had, but have realized more and more that increased capacity gives very little real increase in flight time. More weight makes the model less efficient and spends that energy faster. What it does do though is make the model heavier and at least in some respects fly worse.Freewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion
