That sounds like a pretty good idea. I actually mounted all three servos it the rear opening on the radio tray instead of the middle opening where the instructions call for. I then made a tray in the area the servos were supposed to be in for the battery and reciever, I will post a picture on the build thread though instead of high jacking this thread. I think your idea for breaking in with cowl off probably sounds the best though. I have an eagle tree telemetry system but I need to order a new temp sensor as the old one split. I will more than likely put it in for a while to monitor Temps with cowl off and then once installed to see where I am at.

Thanks
