is this a camera tricks? i met you at joe null and you're a big man. some how with this jet you looks small. how come? oh well i ordered mine and can't wait. should be arriving this early month of oct.

what is the reason for balancing the gripen with the gear down vs gear up? I dont see any detail in the manual saying it should be balanced with the gear down. Like i did the mig-29 cg with the gear up. would you please say how different it would be IF you did with the gear up. that lack of detail on the manual can be very bad for those doing it wrong! I dont know if everyone would watch the video saying so. the battery location in the book also says 70mm back if it is 750 grams. to me it looked like you had it way more back...

[evanroseman]

Will there be a setup/install video for the TV units on the Gripen and Mig-29?

[SantiagoP.]

how much does it cost one of those planes with everything including control and all that stuff?

[frederichussard]

Sur ma notice le CG est indiqué 122mm et sur la vidéo c'est marqué 130mm. Quelle valeur est bonne?

[michaelcuthbert]

I use Turnigy Heavy Duty 5000 60C packs and would fly without TV. I'm wondering if the Turnigy's will fit the battery bay as they are 5mm wider and 13mm higher than the Admiral 5000's and the Admirals seem to be a reasonably tight fit. The additional 55 grams or so in weight shouldn't be a deal breaker though.

so use the 27mm as ur highrate is that what are saying and the 17mm as highrate anyway my jet crashed due bad gyro but will be getting the arf plus next week

[WickedMoto]

How do you measure out the elevons? Because high rate is showing 23mm with everything at 100% but I’m only getting 15mm with everything at 100%. That said, if I move the sticks to the corners then I get the 23mm. So should I overdrive the servo in the endpoints to get to the 23mm? I always like to measure everything out to the high rate and then dial in my own high rate (which like in this video, will be the low rate) and on down.

[carmelocatalano]

can you explain f16 90 mm CG with admiral 5100 carbon? i cannot find it i have problem!

[pokemountain]

Wow don’t have to much room to work with w/o TV on battery placement.. and you moved the strap and it’s at the end of the battery and it was a little nose heavy still. Can it be flown with a 6000mah or is that to heavy?

I want to buy and sell for meI want to buy and sell for me

Gripen is one of the most beautiful jets...so cool to see those two RC Gripens fly
