Dan,
I sent you a PM. You can comment here, in the clear or, answer back in a PM to me.

Dan, How about Small's Estrellia and shark, are those wing strong enough and, are they afford as kits only? And, do you know of anyone that has experimented with 5s batteries in a EF-1 racer, using a EF-1 approved motor and approved APC8x8 prop? I'd like to converse with them about this 5s experimen...

Dan Kane, Is Nitro Planes Miss Dara you're design? If so, How can I make the wing stronger, to with stand the speeds of a 5 cell battery? :D You mention that, the Invictus wing is, one of the more stronger wings that, in you're opinion, (I respect) would be better suited to withstand the speed that ...

Thanks Dan,

Can anyone answer this question?

It doesn't appear in the rules that, I can not (on the leading/trailing edge) grind/shape the Landing gear on a EF-1, and, also the portion of the gear that mounts to the Wheel Pants. To a more Aerodynamic air flow of the landing gear.

Has anyone tried putting a 5s battery in a EF-1 to see what happens? I've static run stock ESC and OS Max and Arrowind motors, 8x8 apc on 5s batteries and got 16000-17000rpm. Have yet to fly them.

Ok,
Maybe I have this wrong about needing only a Rare Bear Motor, ESC 5s battery set-up to go faster in EF-1.
Has anyone run a 5s in a EF-1 motor and turned 17500 RPM, with several flights and, no problems of burned-up equipment?

Thats a good question. I was under the impression that a stock EF-1 motor could not handle a 5s battery. One guy told me, he tired it, (5s battery) an all he got was, a lot of noise and not much increase in speed. I'll try the E-Flight EF-1 motor on 5s and see what RPM I get. See if it over heats, A...

OK, I flew the EF-1 Invictus today using the Horizon Rare Bear 15BL motor and ESC, with a 5s 3300mah battery (to heavy). will try a 2700mah 5s next. WOW, What a difference in speed, Robert Holik thought it was the speed of a 426 +/-, No problems. And Man, does it groove soooo much better. I think it...

Chris, Once again, this Motor/ESC set-up is from the Horizon Rare Bear. This is not a EF-1 motor I'm going to try-out. It's a 15BL 1250kv, I suppose you could use any ESC. My concern besides the airframe holding-up is, providing enough air flow to keep the motor/ESC cool enough. The front of the Bea...

Thanks Chris
