Tailwheel door opening cut....now to make a mount. The bulkhead is located in a great spot for it. Original tailwheel block wasn't mounted very well

Inner gear doors laid up and hinge block glued in place

moparbob498 07-17-2017 06:20 AM

Looking good! Can you still make & install the inner gear doors, without too much hassle? & Are you putting wheel well liners in? My Hellcat doesn't have any installed, so maybe I will have some mods to make with the retract setup...as mine
are hang out just a smidge?? at wheel mounting are- yours turned out awesome so far

n8622t 07-17-2017 10:41 AM

Hey Bob the inner doors were added since I decided not to add the wheel well bays. I decided against the bays because it will make installing the wings much easier. You shouldn't need any liners on your plane since the bays are in the wing....I'd just seal them with some finishing resin then paint them green and not worry about covering the wheel bay with any more than basic strut covers

Have ya'll noticed that Horizon Hobby has a "No Longer Available" alert on the Evolution 160 gas radial web page (https://www.horizonhobby.com/product...gine-evoe7160). This leads me to believe the engine has been discontinued by HH, but they are still selling the Evolution 260 gas radial engine. I noticed that Chief Aircraft is still selling the radial 160.

I wonder if there is an inherent problem with the 160 which has caused HH to discontinue selling it? I was actually thinking about putting the 160 radial on a PT-17 build, but not anymore.

BTW, nice build Jimmy, thanks for sharing!

Thanks Sonny..... here's my first 160 mounted on the World Models PT-17 Stearman it's been a wonderful engine

n8622t 07-19-2017 05:14 PM

I know of three Evolution 160 radials flying. The engines all run the same with zero issues and they are all three mounted on the world models PT-17 stearman I saw that discontinued listing on the HH site.....very disappointing

Those are some awesome mods warbird!!! I'll get on the tailwheel and gear door hook up tomorrow and post a pic for you. I like the upgrade on the guns too. When you have the time I'd like to hear your ideas you used on the canopy. Keep up the good work....
