I had the opportunity to watch this design perform, as there were several P-7 ARF's in attendance at the Classic Pattern Get-Together this past weekend. This thing is a winner. Watching Tony F put it through it's paces was like going back in time, and showed that it is everything that it was back "then". Seeing it go through eight-pointers, long slow rolls, reverse point rolls, figure "M"s etc was very inspiring. It is also quite durable as well. There was a couple of off runway dead-stick landings, as well as one that snap rolled onto it's back onto the asphalt on landing. Damage in each case was limited to scrapes and bruises. (Your mileage may vary).

It is my observation, based upon forum traffic, as well as my personal observations and experience that for those of you who are considering one of the Chinese engines (I am not pointing out any particular brand) that you consider first disassemble the engine, remove and discard the bearings, and replace them with quality bearings such as from Boca Bearings. The bearings that come installed inside of these engines are not up to the job. Even with the cost of the replacement bearings factored in, these engines are very powerful, and are a good value for the buck. Be prepared for people coming up and asking "What do you have in the nose of that airplane?".

I have also changed my mind, and ordered a set of Spring-Air retracts for my P-7. I have had perfect performance from them in my Vertigo II. The are super high quality, and made right here in the USA.

Gear up!!
