The AXI literature reccomends a 12X8 prop for the 10cell pack. Will I be risking damage running the 13X8 prop? I seems to run fine on the ground with short throttle bursts, but I did not want to risk longer runs. Any suggestions would be appreciated."

Thanks, R
its fine

I don't have an AXI. Outrunners are not as common in hotliner applications as regular geared motors, so probably fewer people can comment.

I'm guessing you can, fly it for a couple of minutes then bring it down and touch the motor..

i'm flying that same setup but with 3s

3s has more voltage than 10 cell, so he is fine...

Soho - the best voltage I get out of 3s is 12.6v, and I routinely see 14.8-15v from my 10 cells... 2/3a and sub c packs.

Not picking a fight -

That's charged voltage, Jim, not voltage under load. Depending on the cells (both LiPo and NiMH), I can get more voltage from 3s or 10 NiMh's - i.e. hot GP2200's will deliver more voltage than 3s 2100 LiPo at 50A.

Yep - posting before 5:00 a.m. is not a good idea - I should have considered the "under load" disclaimer as I'm sure Soho intended.

Thanks for the help, guys - I'll fly it with the 13X8 blades and just check the motor temp to be safe. I am not flying continous throttle anyway. The controller should handle it fine as it is rated for 70A. I also have a set of 11X8 which I may try for curiousity.

Siren servos

what servos have you fellas used with your siren? Would a HS55 be enough? Or should get something more beefier?

I've read some have used HS-55s, but I think something beefier would be better. I used HS-81s on mine. The HS56 or 65 would also be a good choice, but more expensive than the 81s I think. Remember, the Siren is a warmliner...made to climb and do hi-speed passes. The faster you go the more aerodynamic load on the servo...that' be a bad time for a servo to stall/strip now wouldn't it...

IN keeping with the inexpensive nature of the plane I would use hs81s... they fit, and they work.

I used 56's on the ailerons, and a 55 on the tail. I'd probably use 56's all around if I did it again, although I've had no problem with the 55 in there now..

Hi Guys, new to the site and just bought my first hotliner.....The Siren. Is there any advice on how best to thread the servo extension leads through the wing . I know there is a piece of string already threaded through centre wing ribs, but what is the easiest way to attach the string and thread the leads as the openings in the ribs are quite narrow.

Thx in advance for your replies.
