[NSRCA-discussion] For Sale

I recently bought a heli with 2100-3s packs and I have been slowly working my way towards an airplane that uses these packs.

What airplanes-size-weight are you using with these packs?

The Vanquish and Brio 10 need more than that..

  Jim,

  A couple of years ago I would have agreed with you. Glow was a known for me, electric wasn't. But for the smaller planes I will probably never go glow again, electric is just too easy. But, yes, there is a learning curve and up-front expenses going that route. Once you have 2 or 3 planes with similar setups, the batteries can all be shared (I have a lot of 2100 3S packs and associated planes). 

  I have a Vanquish and a 3DHS Aspera which I both love. I think going glow would not improve the flying any, and the associated cleanup of glow would take some of the fun away from it, JMHO.

  I would love to see the glow setup fly, though.

    I kind of detest electric stuff - for a while longer anyway - I'm still in mourning over my 2006 nats e-meltdown :) I'm one of the few pattern pilots who went electric and said "no-thanks" after spending their way through it.  I really do not want to buy $50-$80 battery packs, when I'm carrying 30% heli fuel everywhere I go.  

    I have a little bit of experience in this.  I have an Extreme Flight Mini 3-D with a GMS .32 that absolutely screems and has great throttle response.  The GMS .32 swings APC 11x3 at 13,100 rpms as measured this weekend.  The vertical speed on this plane is incredible, yet with about 15 degrees of flaps it will almost hang in ground effect and lower vertically for landing.  This little plane garners a lot more excitement at the local club than my 2M planes.  Maximum fun, minimum investment :) 

    Is this experience a fluke? Is the cheapest motor you can buy ever going to be good enough????  Would I ever buy another one that ran as good as the first????

    I took the Extreme Flight E-Extra 300 and converted it to a GMS .32, this time buying the luxious 'remote' needle valve version.  After lining everything up, I also used an OS muffler extension to get the muffler futher away from the plane.  This plane came out just about exactly weight wise to the electric versions which fly on 3S packs - worse-case 1.5 oz heavier.  I installed the rudder servo in the tail.  I also used Futaba 3101 and 3102 servos, which are larger that whats called for.  The result?  This plane flys amazingly well!  Vertical speed is so fast that it will just make you belly laugh!  It is fun as heck, and like all the EF planes, flies much "bigger" than it is - cool success so far.  It is a shock to see landings for a plane this size, slow, float, and land, where as even many other electric small planes get to a point where they just "drop" out of the air.  This one is way-cool.

    Thinking about the Vanquish, and the way-overpowered flight characteristics of the Mini 3D and the E - I mean G-Extra 300, I figure the same motor package on this slightly bigger airplane will do just fine.  Also, the Vanquish flies on a 4 S pack which weighs about the same as the GMS .32 in itself.  Actually, I'm figuring that a G-conversion would come out lighter than the E-versions. In all actuality, the fuel proofing has been minimal.  

    Here is an agregious non-sponsored plug!  BUY EXTREME FLIGHT R/C STUFF!!!!!!!!!!  Any plane, any thread you'll read, exemplifies the product, service, and flying qualities.  These little planes fly very very well and I'm much happier with them than a foamie type plane.  Plus, you can fly the Mini-3D and G-Extra 300 in a park.

    I do see the benefits of leaving it electric though, and Cameron sent me an email saying I could fly his at this contest.  I'll go for a flight and see.  I'm still leaning towards another GMS .32 or possible a Webra .32 though :) If you do a weight veruss HP study on all the .25- .30 class motors, the GMS and Webra stand out as the biggest bang for the weight.  Hey - this stuff is about modeling and having fun right?
    Thanks,
    Jim W.
