Status: online 		ok here is my story
i have a 3D CMP Giles 202 , about 6 lbs. i see that i am to use a motor thats around 1200watts. from there i start to get stressed out and not know what to get for a battery or speed control.
i get stressed out cause with glow i throw on the engine add the fuel give her a tuning and after some flipping and a little bleeding and its started. well until you get a dead stick .
i have heard that there is something you can use so if your esc fails you dont lose control of the plane.
also the prop, the motors that i have looked at say i should use a prop thats 14 - 16 in length. that will be too big and hit the ground, so as i said im way out in left field here and would really like some help
thanks jeff

I use a separate battery to run my RX and servos instead of a BEC. If you want to run a 2S lipo to run your RX and servos you will need a regulator, and I would suggest one with a failsafe switch.

An electric motor is just like a glow engine for all intense and purposes in that it puts power to the prop. If a 14" prop is too big you can always go to a smaller prop with more pitch. The nice thing about an electric is you can put a watt meter on it and see if the prop choice is too much load.

Now for your battery and ESC quandary, the motor will have a suggested cell count range and maximum amperage draw. Once you know that getting what you need is pretty easy. I have an Ultimate bipe that is slated for a conversion. the motor I bought for it is 70 amp max draw and will run 5S so I will use half of my pattern packs (5s 4000mah pack) to run it. The reason for the high mah in my application is that I have them and won't need to buy yet another pack for this plane.

I hope that helped clear up some things for you.

Pete

You can use a Hobby King easy match 46, Monster power 46, Tacon 46, EMP 46, 5s 5000 mah battery, 60 amp ESC turning a 13x8 3 blade prop should give around 9 1/2 pounds of thrust.

I use a Monster Power 46 in my Giles 202 46 sized and it rips it off the ground. I am swinging a 12.x6.5 and have a real good time.

The meter will be cheaper than any decent motor or speed control.. It will save you money and pain !

Status: offline 		Hey man I'm a newbie to electric too.  Everything these guys are saying is true.  Blvdbuzzard has especially been helpfull in answering any questions I have had.  He is a very knowledgable guy, and he got me into the budget shopping thing.  All those websites he mentioned are very inexpensive, but I stumbled accross another company that is just as cheap and their warehouse is based right here in the states.  www.valuehobby.com        Check it out.  They should have what you need, and I got my order in less than five days.  I try to buy american and if I can't which you will be really hard pressed to find any electronics components that are made in america these days, then I at least try to find companies that are based and distribute here in the states.  The watt meter is pretty awsome.  I bought mine from value hobby and I would say that it is just as good as any of the higher priced one out there.  They have two different ones.  One is rated for a MUCH higher amperage so make sure that is the one you get.  Cheap batteries too. 

Thats what little I can contribute



Danny
