Default Rcgf 56

I looked for information on the RCGF 56 gas engine and could not find anything. I have been running gas engines for a few years now and I have a new project in a Phoenix 30-35cc P-47. I had a EME 35 but this plane is bigger than some of my 50cc birds so I opted to install a 55cc gas engine. I bought the RCGF from Valley View and it looks like a very nice engine. I have it mounted to the P-47 and it fit inside the cowl perfectly. I will do a test run on the engine this week and post my finds with 2 different XOAR prop sizes(21x10-22x10). Here is a couple pics of the engine mounted to the Phoenix P-47.

Well the Pitts muffler came in yesterday and I got it installed. It took a while to get the engine started. It was not pumping fuel so I primed the engine by shooting a little gas into the carb. I then flip the prop twice and she started and ran for a few seconds. I then choked the engine and flipped the prop about 10 times and finally got a pop. I closed the choke and she started on the second flip. I let her run for 10 minutes going from a high idle for mid-range on the throttle. I shut her down and let the engine cool for about 15 minute. I then filled the 16oz tank back up and she started on the 3rd flip without being choked. I ran here for another 10 minutes varying from idle to top end. I have a Xoar 21x10 prop installed and I am getting a good 2000 rpm at idle and 7000 rpm at top end. I only stayed at top end for a few seconds just enough to get a good rpm reading. So far I am very please with this VVRCRCGF 56.

Well the P-47 is finished and I could have not intalled a better fitting engine for this Phoenix P-47. Here are a few pics of the plane and you can see the RCGF 56 with pitts muffler was a nice fit.

Default Pitts muffler

I used the RCGF pitts muffler from RCGF USA. It was a perfect fit.

What kind of structure does the firewall and engine mount box have behind it? There sure doesn't look to be much to keep it in place if you were to doink the landing. Nice looking plane though.

The firewall and engine box have 1/2 plywood with tri-stock clued in place. I added some more tri-stock on the inside of the firewall and fibeglassed both inside and out side of the engine box and firewall. This is the Phoenix 35cc kit and those that used a 35cc gas engine had to add 1.5lbs of weight to the nose to get it to balance so I decided to just install a RCGF 56 and reinforce the firewall and engine box. That worked out really well I did not have to add any weight to get it to balance.

jstanton,

Have you had a chance to fly her yet? P-47's are typically good flyers. I am interested in your flight report!

I have not had a chance to maiden her yet but I have high hopes. I have had to go to the hospital everyday for the last 2 weeks with my mother in-law getting over a stoke. I hope to do the maiden flight this Thursday ofrSaturday depending on high family things are going. I will post a flight report and if I can get someone at the field to help with the camera I will have a video of the flight
