RE: what is the best/diffrent ways to secure the batteries for the engine??
I have seen some really elaborate installs for batteries . . but I think the Velcro strap system is the easiest to intall packs (and adjust CG). Velcro on the tray and between packs, then straps over . . they won't budge ! Try and pull the packs out of your plane with the Velcro straps done up . . seriously ! ! You will make a mess of your fuse, I bet ! Probably just keep an eye on the fastenening strength of the Velcro . . I imagine it does wear [8|] JB

RE: Sebart Wind 110
Yes Wilson . . you are a LEGEND ! ! [;)] The new baby is fine . . breast feeding it at the moment [:D] I think ESC / Motor braking is another great benefit of electric power. It is probably less necessary on some of the glow/hybrid designs. The bulky fuses, thick wing sections and thick TE's tend to create reasonable drag and slow the plane on downlines, it seems. I can tell you one thing for sure, the Wind S Pro has a thin fuse . . much thinner than the Integral (but almost as deep), thin wing section and thin TE's. So I think ESC/motor braking is necessary. If it were glow, I am sure it would accelerate dramatically on downlines . . but it is an EP design ONLY. Cheers, JB

RE: Regulator Voltage
Great info, Ed. I understand the performance of a servo is increased at it's higher rated voltage, but is the servo life dramatically effected? Is it measureable? I run 6V (or as close as I can get to it) for servo speed and torque on most of the planes I fly, and I have yet to experience the potential ill effects of too higher voltage. Maybe I dont' fly enough [;)] (although I do fly more than the average club flyer). JB

RE: Angel S EVO Build Thread
YES . . Matt13 is a friend who bought the Angel off the OTHER friend [:D] A 16" prop will work OK, but I understand the 17" gave it more authority (he did a lot of testing with this plane . . and he is a VERY good pilot - F3A Masters ranked). I believe it is a APC 17 x 10E, but maybe Matt can chime in and confirm. Your 6S set-up will be fine. Could have run 4000's . . that would have been more than adequate, and saved some weight. Cheers, JB PS. Yes, the kV is almost the same as the Hacker A50-16S . . which needs to run 6S in this plane. When you mentioned "which size pack to go for" . . I thought you meant Cell count. e.g. 5S instead of 6S to reduce the weight. 5S would turn this motor too slowly.

RE: Is EP ready to downsize to 8s?
I noticed on Silvestri's website, he lists two recommended power options for his Wind S Pro (as below). A typical 10S option and an 8S set-up. I would imagine that Silvestri has done testing with both these options, so I guess the 8S works. Although . . to get similar performance to 10S, I expect that the 8S option would "work" the packs harder, reducing the pack life. So . . it could work out to be MORE EXPENSIVE than 10S [X(] I think the only obvious advantage to the 8S set-up is the weight saving. [i]Wing Span 189 cm Lenght 199 cm Weight: 4.600 gr.

RE: MODEL TECH 2M REMEDY
Lots of different theorys out there . . Pattern planes have had razor sharp TE's through to the current trend of thick TE's . . and flutter hasn't been a concern with any of them. Sealing the hinge gaps, correct linkage geometry and servo choice, is considered the appropriate method of handling flutter. 3D throws are a 'flutter' concern, particularly when using analog servos (not recommended), as small amounts of servo travel are used to control large surfaces for general flight (i.e. low servo resolution). The attached pic is of Gerhard Mayr's own design . . it finished 5th at the World Champs, so I guess thick TE's work as intended for him. Definitely most new F3A designs do not have thin TE's and the rudders are surprisingly thick. I would just build it as it is, and wouldn't bother sanding the TEs down . . doubt you would notice any difference in flight. Cheers, JB
