WMAC Group build - Impressivo

Re power train - I can see that some fliers might favour the extreme Multiplex option but if we all stick with an average power and cost set up, i think more members will adopt the concept and any fun comps will be more meaningful.

I agree Kevin, we should go for matching set ups, I already have some 3s 2100 25c packs, so that's what I will be using!

Hi mike, can you add me to the list for this model as it looks a good choice for a build. After flying the foam jets in a large group it was a lot of fun and if all powered simularly it would be good.

OK, Simon. You're on the list - see post #2

I just took another look at post 2 to refresh my memory and saw Mike's note re my building board, for the record our kitchen table is 6ft 6" by 3ft, I think that should do, it's only the consent for change of use that I lack!

I agree with Kevin and Jon that a cheap power system is desirable. In fact, I've done a little more research on the power setup and found an outrunner that could also work well according to the reviews.

Turnigy 2836-3200

Benefit over the inrunner is less weight at only 72g compared to 109g. Disadvantage is it only has a 3.17mm shaft (but the bearings are 4mm i/d, so if it bends you can replace it with a 4mm shaft). Also, having less thermal mass it might run hotter. But, there's only one way to find out so I've ordered both and will run some tests to find out whether one is better than the other.

Both motors have a kV or 3200rpm/v so should perform similarly. Reviews indicate that pylon props (5x5 for example) are turning at over 20,000 rpm on 3s. Some guys are running these motors on 4s and quote 38,000 rpm, so there's room for an upgrade in performance later if you feel the need :evil:
