WHOA!!!!!!!! That's IMPRESSIVE!!!! Very nice work Thebiulderofthings!

. Now here is one of the firewalls. It's 1/4" inch aircraft grade plywood. I've already got the holes drilled for the engine mounts, but there is more, watch.

Awww. Now you just embarrassed me.

Now, doesn't this machine demand a pilot licence, the one for multiple engine birds? Most impressive!

 

[Thebuilderofthings]

. Because this firewall will have the main landing gear attached to it there will be another 1/8" inch plywood section with blind nuts sandwiched in between for attachment and added strength. I'll show you what I mean. I am now taking the firewall and using the dead centering tool to mark the holes on the 1/8" ply disc behind.

 

[Thebuilderofthings]

. Now here is the backside of the firewall with the blindnuts ready for attachment.

 

[Thebuilderofthings]

. And hopefully here is where it all comes together for you. I only needed to recess two holes as the other two obviously weren't needed. These will now be epoxied together. Now the engine can be mounted to the firewall. The slots are for the nacelle spines to pass through. These are what everything hang on.

 

[Airframes]

Excellent work, very impressive!

 

[Thebuilderofthings]

. And here you go with the engine mounts ready to go now. The engines will be mounted inverted to maintain scale appearance.

 

[Thebuilderofthings]

Excellent work, very impressive!

Most kind of you! So where do you hail from?

 

[Airframes]

I'm originally from the North East of England, but now live in the County of Cheshire, about 20 miles south of Manchester, in the North West of England.
It looks like your B17 is going to weigh a fair bit, so I presume the engines must be fairly powerful?

 

[vikingBerserker]

Wow, this is some pretty impressive work. Do you have any pics of any other prior builds?????

I'll be using four four stroke engines. They are .91 cubic inches each putting out 1.6 HP a piece and will swing a 15" inch three blade prop. They are made by a company called Saito.

This is a 1/5th scale Mustang with an 84" inch wingspan. It has a 5 HP 62 cc. chainsaw engine in it. You can barely see the instrument panel from here. Elevator, rudder, ailerons, flaps, throttle and retractable landing gear including the tail wheel which also steers. All up weight 23 lbs.

. These are elastomeric inserts. They help keep vibration down to a minimum. A must to help prevent airframe fatigue and radio and battery component failure.

 

[Thebuilderofthings]

. And here is one of the 4-stroke engines mounted in it's intended position. This engine has already been broken in on my test stand. Nice steady idle,transitions great.
