Yup
BTW
I got my 14 bats today, customs delay but Fedex ok
it is cheaper and faster to ship Fedex from HK than Canada post in Canada, lesson learned.

Yes, from Luck A Lee
Ordered from Hobby King on Sunday, shipped Monday, slowed down for a day by customs in Canada and received on Thursday.

Hope to try some 180mah out in the Arrow, Axis and Click this weekend. Until now I had been primarily flying 450-460's in the Axis and Arrow BUT now that I have tried the difference in weight between a 250 and 450 I want less weight over longer flight.

Interested to see your results... power / 'punch' will be the interesting factor. I've used the 180's before and there's a line between weight savings and punch factor - ie. burst current capability.

That is, a 180 mAh 25C lipo can handle 0.180 * 25 = 4.5 A burst amps; whereas, a 450 mAh 25C lipo can handle 0.450 * 25 = 11.25 A burst.

So if your prop/motor combo is in line and your static full throttle current draw is below the 4.5 A then you should only notice the benefits of less weight. If, on the other hand, your static full throttle current draw is above that 4.5 A I think you'll see something in between loss of punch and the benefit of less weight.

Sorry for the ramble.... I'm just eager to hear back your results/impressions. Hoping, of course, that it works out positively.

Cheers,
J

Re: Blue Foamie

Thats exactly right. Was saying to Gaston I will build a lite version FoamStar but everytime i am heading that way it gets cancellef on me, grrrr.

Will post some info of all up weights with 180 and 250 bats as well as performance. I think 180 will need sub 130gram, 250 is awesome with sub 140 gram, fun to see.

Cheers
