Looks like this thread was slowing down a bit. Anyway, I finally got to maiden the ROC V-Tail this morning as the weather was superb & our field was cut yesterday. My V-Tail is pure stock except for the 4' carbon fiber rod I replaced the stock one with. All my control surfaces were set perfectly, the wattage test done, all the servos run thru an operation for 10min of continuous operation to check for failures, CG was spot on with a 2200mah battery, & glide test done successfully with no issues.
Half throttle with a gentle toss forward & it climbed nicely & then adding full power to get to altitude for 30sec. Power off, only trim needed was 2 clicks of UP Elev for level glide.....PERFECT!!! It was beautiful to fly & after a couple circuits around the field, I played with some maneuvering to get the feel of the AIL & V-Tail RUD/ELEV throws....no problemos. I flew at 100% with no Expo or DR dialed in. Next was testing the flaps with a slow graduation of input of my left slider on my JR10X to check how much nose-up took place to determine if any down ELEV may need to be mixed in. Nope...a very slight nose-up attitude & the slowing down was quite noticeable.
I did several more climbs, glided lazily, & decided to land to observe the flap engagement with a steady slider movement to full flaps. Absolutely superb & the first landing was within 30'. Battery check with a total time on the Tx at 17min/45sec showed 55% charge left with cells at 3.86. The next battery was to test the number of 30sec full-power climbs I could get with an emergency reserve as I did with my Radian. Surprisingly, it was the same....(7) 30sec full-power w/reserve with the 2200's, & (5) with the 1800's with a residual balance at 30%(3.71v/cell) for each.
The ROC V-Tail is definitely a KEEPER!!!
