because he’s trying to copy and follow the innovators. We all want the
triple volumetric 2 meter bird because that’s what Chip/Andrew/Quique and

with nooooo problem. <o:p></o:p></span></p>

will help the average guy for a year or two. But then the innovators will
once again push the limits (they wouldn’t BE limits if no one was pushing) and
we would see new designs that the average guy can’t easily keep within the
rules.<o:p></o:p></span></p>

color:#1F497D'>Bipes have not really caught on because they’re too difficult to
make weight with. Only the very best builders with very few limits on
funding for all the best and lightest equipment have made them work. Add
a pound and that will very likely change…to where all the top guys can make
them work, which will then push the average guy to try and make them
work. At the end of the day, all it adds is cost as we obsolete a
whole generation of viable aircraft to the dumpster. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>All one needs to do for confirmation on that is to review the
evolution of aircraft that occurred when we removed the LAST limiter…engine
displacement. Prior to that, weight was only a secondary limiter
because displacement restricted how big of a plane you could carry
around. Once removed, we had 10 years of growing aircraft and growing
engines. All costing more, NOT just because the new stuff was more
expensive…that’s just natural inflation and evolution, but because the lifespan
of a model was shorter. Designs changed SIGNIFICANTLY every year.<o:p></o:p></span></p>

aircraft like the Integral enjoying a 5-6 year run and is still considered competitive
even in FAI (I believe that’s what Pete Collinson flew in the finals this

I'm concerned that these new electric only planes that are designed to make<br>
weight won't hold up to the normal wear and tear of an average intermediate<br>
or advanced pilot or flying off of a rough grass runway. Is this a
valid<br>
concern? I think so but maybe I'm over reacting. That is why I'm
in favor<br>
of eliminating the weight limit altogether. The proposal to slightly
raise<br>
the weight limit won't allow someone to fly an electric Focus II for<br>
example.<br>

I've been following this with interest. E-power is looking better all the<br>
time and I probably will make the change. I like to build prefer a wood<br>

empty airframe ready for radio etc? Any numbers readily available would be<br>

RTF electric at 10.25. There are some airframe examples for which glow
/<br>
electric are similar weight, but that is not the norm - not yet anyway - my<br>
opinion.<br>
<br>
My electric Bravo was 10 lbs even at the 2009 NATs (only 4 oz more than the<br>
Vivat I flew in 2005) and I would be scared of the structure if it were any<br>
lighter. Of course it could be lighter still IF I went from 5000 to
4350<br>
lipos (~6 oz) and ditched the dual RX batts and Vregs (~2 oz) and used<br>
lighter ESC and wiring (~ 2 oz).<br>
<br>
Point being....even tho 10 lb electrics are possible, and becoming more<br>
common, it is still pretty easy to build electrics at 11+ lbs without<br>
careful planning and attention to detail. I think it will become a<br>
non-issue soon enough.....even in Europe and Asia electrics are coming on<br>
strong.....so the glow kits will become increasingly scarce.<br>
<br>

I would argue that you can't "disregard" the airframe given that an
all<br>
electric airframe is much lighter.<br>
<br>
My answer to the question? There is almost no difference. I'm
flying a<br>
full 2M plane that weighs 10lbs 4oz with light batteries, 10lbs, 8oz with<br>
very heavy batteries. My two Black Magics with glow weighed
10lbs 6oz and<br>
10lbs 8oz RTF minus CDI (add approx 4oz for that).<br>
<br>
I believe we're just now seeing full electric designs that are optimized for<br>
weight and are coming in light. Prior to that, many of the
designs still<br>
had unnecessary structure as a legacy from Glow. I'm pretty sure that<br>
evolution is not complete yet either.<br>

Tough question. Will you insist on using 30C lipos, when 20C lipos<br>
are much lighter? Do you plan on using a particular motor? Motor<br>
weights vary substantially. Some ESCs are a lot heavier than others.<br>
<br>
My guess would be that the weight difference between a complete<br>
electric-power system and a complete glow-power system, disregarding<br>
the airplane, would be 10-16 ounces.<br>
