Mig 7

[bassman1972]

Hello :)

I need your help.

I made a Mig7 on coroplast, which was a bit heavy I think.
Airplane more battery 700gr (25 ounce). :eek:
I do not want big races I thought of putting an engine
1100kv with a 9x4 propeller to gain a little strength.
However the result was not the best, early on I had a fall and although it has all been very fast I was feeling a lack of strength to pull the plane because it appeared that the plane could not gain support or go to the air under engine.

That felt lack of strength and speed. :confused:
This was my first construction give my doubts.
In your experience what would be a good option for this engine
device.

Thanks

Interesting project, but too few details to offer an opinion. What size is the motor/battery? For a 1100kV motor I assume you are using a 3cell lipoly battery. Something around 200watts should get it moving. I have had good luck with these motors - Turnigy 2217 16turn 1050kv 23A Outrunner

Plenty of user tests can been seen there.
