I am all most done printing it out and I noticed that the nose looks solid with no hole for the propeller shaft. Is that so or is it just the way it looks in the rendering? If the nose is solid what size hole do I drill? Also would it be possible to get the hose hollowed out because I have some old cox gas engines that I may mount on the model just to see what happens. I will post pictures and if I put the gas engine on I will try to post video of it flying.
