With that I would have to switch out the ESC to at least a 40A I would think. I use 3S 2200 mah 25-35C batteries w/ 10X5 APC prop. Any opinions or experience on going this route to try and enhance the performance a little would be appreciated. Thanks!
The Park 480 is a good upgrade from the stock motor and will bolt onto the stock motor mount, however, you will probably have to reverse the prop shaft. I am using the Firepower 480 sport 11 Kv from Heads up RC, bolt on and prop adapter supplied, less $ and 2.00 shipping to 48 states.

Dennis,

What kind of flight times are you getting with the Firepower 480 and with what battery size? My flying style is relaxed without trying all the aerobatic maneuvers.

I had tried the Firepower 10 size and was unhappy with flights of 5 min or less.

Just curious.

Roger, I'm using the Zippy 2200's, fly somewhat aggressively, and set my timer for 7 minutes. I generally put 1200-1400 Mah back in so there's room for more time. When I was practicing T & G's and doing lazy circuits I had my timer at 10 minutes with about the same usage. I hope that helps.

Yes, that does help. The Firepower 450 size seems slightly mushy at times but it gave the flight times I wanted, About 11 and 12 minutes without pushing the 2200 mah 3s battery. But if the 480 gives 10 minutes with a few T & Gs I could live with that.

Thanks for the information.

Roger

Roger, I forgot to mention that I am still using the stock 10x5 prop.

An absolutely stunning day here in North Alabama. Managed to get in two flights today even with everyone else at the field. I had not flown my Sensei in probably two months and it was good to get her back in the air.
I cut the throttle on final hoping to get her to drop down into the glide path, but she just kept going. That was with only a 2-3 knot head wind.
Stock setup is working great for me, the guys who do the training in my club really like this as a first airplane.

I have a small crack on the front wing attachment from a transport accident, can I use regular CA or does it need to be foam safe? I need something very thin to get on there and don't have any thin foam safe CA.
Thanks for the help,
Jimmy

My suggestion would be to slightly open the crack and get Gorilla Glue into the crack. Then use pressure to close the crack, use 3M blue painter tape to secure it and allow 2 hours to completely cure. The glue is stronger than the plane.

To second Dennis' comments, I used the quick-drying Gorilla Glue to fix a crack and it worked very well. Definitely use blue painters tape to keep the glue from foaming out, that forces it down into the crack.

New sensei owner,

I have a new still in the box sensei (to cold to fly here in Mi.) and have been going through this thread. I was thinking about pulling the stock motor and esc out of my pz p-47, it is a 15 BL Outrunner motor, 950Kv by ParkZone (PKZ5116) with the alum prop adapter / 9.5x7.5 prop and 30-Amp Pro Switch-Mode BEC Brushless ESC (V2) by E-flite (EFLA1030B). I think I will have to push the shaft thru the motor for mounting and reverse the throttle setting in the tx.

What about using the p-47 motor mount that is shown in the attached picture

I am looking for opinions about this setup.

Thanks
Howard

Hi Howard,

If it was me I would leave it alone and fly it as a standard first. However, I am one of the advocates in this thread that removes the spinner. That allows a lot more air under the cowl to cool the motor and ESC. My thoughts were that cooling may have been part of the issue on the reported failures.

The plane is underpowered as sport plane but I thought was just fine as a trainer or sedate flyer but I would try it as is then decide if you need to repower. I only repowered mine as it sat on the top of a Cedar tree for about 10 days and through two storms. The incident was because of a failure of a connection to the battery and not an ESC or motor problem.

Too cold here to fly comfortable as well as health conditions keep me from challenging the cold. It also got kind of deep the last three days so skies are in order.

Good luck and you will like that Sensei.

Roger

Howard, As Roger said, fly it stock before you make any mods to the plane. This will give you a feel for the plane as designed and insure that you have it set up properly. If you find that you want more power, an economical upgrade that bolts in with no modifications is the Firepower 480 Sport from Heads Up RC. I have been using it for nearly 6 months and find it a solid reliable power up mod from stock. The Park 480 is also a viable choice however, it requires reversing the shaft and is more $ than the Firepower motor. Good luck with your new plane.

Dennis

Ditto with Roger's comments. I took the spinner off, it certainly helps with air flow. I'm still flying with the stock electrics, she has plenty of power and I get 9-10 minute flights with throttle 50-65% most of the time. Plenty if you are learning, you can always hop her up later!
