Here are a few pics of what I did with the ladybird canopy. Just heated a little metal rod, poked a few holes, sprayed flat black and then added a little strip of thin clear plastic on the inside with tape.
I think it looks much better and the canopy is so tiny it took very little paint, so I wouldn't think the wait gain would be much. I really need to invest in a scale like many others have on here.
The lines of the head and wings are still there but don't look bad. However, for someone that has the minipet, can you confirm whether or not it has any divots/lines in the canopy or is it just smooth all the way around? (edit: nevermind found closeups on BG) If so I might pick up one of those instead when I order the 300mah lipo's and also am probably going to pick up a v929 canopy and do the same look for my mqx.
