With the rimfire and a 10x7 apc e prop I get 330 ish watts and 30 amps. I haven't yet begun to wring this thing out either.

With this setup she pulls GOOD vertical and covers ground pretty quick. After I get some time on her (I've only got about 8 flights on her) I'll prob go with a 11x7 prop. I think that'd be WAY enough.

Anyway, I'd highly recomend the rimfire, fits great, plenty of power, and it's a $teal! I think the 12x6 might work, but definate throttle management and maybe 25c packs would be in order.

I kinda did this one on the cheap too, I have a bunch of 2200 3 cell lipo's and I opted for Hitec HS 55 servo's. The only one I worry about is the elevator servo, but I don't have her at 3d rates yet, so I'm not worried for now.

I do rog's on grass. The wheel pants drag her down, but just hold full up elevator on high rates (not 3d!) and shell come up in 30 feet or so. I had some prob's in the beginning, but keep that elevator up! Grease the landings too, or it'll nose over. You can underhand toss this thing too.


I highly recomend this bird, it's a gas! I can't wait to spend more time on it!!!!!!!
I have a coupla' 2200 25C 3s...but they're kinda porky at 6.7 ozs. I don't think that would effect the wing loading too much....I'm curious how the 12x6 does on 3 cells.

What was the kv on that motor again?

2.25" wheels work nicely on "ugly" grass. On the 10x7, I get off the ground in about 10-15ft.

Thanks for the link to the CF gears. Looks like the 120mm gears should work. Seems like the 60mm swept forward would be too much. Any advice?

I dont know if the sweep angle makes any difference but I would think the 120mm would be a nice snug strong fit.

The motor is 1200kv.

It seems everything has gone up! I paid $31.99 for motor and $139 for the bird! Now it's $40 and $150! Sheesh!!!!!!!!!

Tower just sent out another $25 off $150 coupon. Cash her in!!! Usually I place 2 $150 orders separate and get $50 off. Kinda nice, no shipping, no taxes!

Maidened mine this weekend - WOW. Off grass, it wanted to nose over, so it needed a bit of up to keep moving. Once it was off the ground, it needed a few clicks of down, but otherwise trim was good. I set up my D/R with high and 3D rates from the manual with a good amount of expo. After a couple circuits to get familiar with it, flipped the switch and did a max deflection roll, which prompted a unanimous "Holy !" from the peanut gallery. Rolls are a blur, doesn't care if it's inverted or upright. Planes like this are making the glow guys at our field consider electrics...

Cool! Yeah, on high rates, mine is indeed a blur when rolling. The scary part is I think I can still get a little more deflection out of my ailerons!?

For sure!!!!!!!!!! Man, I got "wows" out of high rate rolls! Next time out I'm going to make the low rates high and high rates 3d. I hope I don't kill it

I can get all most twice the travel that that the 3D rates suggest. I have not flown mine yet but I was asking if these were correct as most all my 3D planes have the control surfaces set to move 45 degrees where with the Reactor, the 3D rates are like 20 to 25 degrees. Has anyone else set their control surfaces to move 45 degrees?

Pull out from hover

Has anyone have any input as to how the Bipe pulls out of a hover with the Rimfire motor and 2100 battery?

I have not heard anyone say anything about the pull out and there is no pullouts from a hover in any of the videos I have seen.

Can anyone give any input?

Thanks,

Not that I hover well (can hold it for 3-4 seconds) but...with a 10X7 and Rimfire on 2500 it'll pull out fairly well. It's not a rocket out of hover on that setup but it still pulls out well. I've never tried it on the 11X7 but that prop does have considerable more pull to it. For what it's worth...
