    Status: offline     		I still need to measure the current and RPMs on my 26-cell setup. I expect around 100 watts per pound.

    On 20-cells, it draws about 40amps for 86w/lb.

    I'll measure it this weekend.

    Status: offline     		The dummy air scoop was converted into an active air scoop that would draw air into the fuselage to cool the battery packs. The MaxCim Charging jack provides for re-charging my flight packs right in the plane. The Remote LED diagnostic indicator allows me to test for proper controller operation at a glance...a true convenience!

    Status: offline     		Wow! What a nice conversion! I fly a slimer TF AT-6 and love it, but it is my last IC airplance and will sell it this winter, going all electric! The H9 AT-6 looks like a nice replacement.

    I have a question on using dual LiPoly packs. How do you charge them? If I used two TP 4s4p packs in series for power, do I just charge them one at a time?

    Thanks

    You would charge the pack by the number in Series, so you would charge as a 4 cell. What kind of charger do you have?

    Status: offline     		I have a Great Planes Triton, good for 4 cells of LiPoly. I would be worried about balancing the charge in the packs if I charge the two 4s4p packs by themselves and then connected them in series. I know of know charge that will do 8 cells of LiPoly.

    Thanks for reply

    Status: offline     		At one time, one of the expensive German chargers claimed to be able to charge up to 9S.

    Now, don't take my word here as law, but I think it's actually safer from a cell balancing standpoint to charge LiPolys in parallel than it is to charge them in series. As long as the two packs start out in fairly similar states of charge, they will automatically balance as they charge in parallel.

    it works fine, and it is capable of 12 pces in series charge.

    Status: offline     		My review of the Hangar 9 AT-6 Texan should be published on RCU any day now.

    Look for it in the magazine section soon.

    Status: offline     		Hi Greg,
    What did it cost you to build the entire thing (from start to finish)? Just curious as I am planning to get the same AT-6 from Hangar 9 but Glow powered.

    Thank you
    Kris

    Status: offline     		Hi Kris,

    Here is a breakdown of the costs. The e-powered version is definitely more expensive but has an advantage of keeping it look new longer and produces much less vibration. Either way, this model is a beauty and fun to fly! Good luck!

    • AT-6 Texan $250
    • MaxCim Motor/ESC/Gearbox $500
    • 4 servos $60-$120
    • Retract servo $30-$60
    • Batteries $120
