Hi John look great! I actually bought a DA100i to do the same setup. Any chance you can share more details on your firewall and the angle you rotated the engine? I sent you a PM with my info. I would greatly appreciate it.

Thanks

Hi John, same here..looking to do the DA100i also! any more detailed pic's would be appreciated as well.

Thanks,Vincent

I don't have pictures of the steps I took to achieve the results. I will try to explain using what pictures I have.

First, I asked Kevin at J'TEC for a muffler with the "can" moved as far forward as possible. J'TEC has the info on file.
Next, bolt up the stock firewall omitting four blindnuts for the cowl. I wanted the cowl to be mounted separately.
From the inside, scribe a pencil line of the flange the firewall is mounted to.
Then, I held up a piece of 3/8" aircraft ply and scribed the inside of the flange to it. This will be the spacer. Cut it in the shape of a horseshoe about 1" wide. Be sure to cut it about 1/16" undersize so it will fit inside the flange with a little wiggle room.
Now make your new firewall to match the spacer. I used 3/8" AC ply.
It gets a little tricky here. Lay the original firewall on your bench, set the engine on it so the exhaust pipes line up with the bottom of the plane and you center the engine in the cowl. Now mark where your cylinder and exhaust are and cut out the original for clearance.
Epoxy the three pieces together and there you have it. I don't know if it was needed but, I through bolted some 4-40 bolts for added security.
Now for the cowl mount. I added 1/4" phenolic blocks to the face of the firewall to move the cowl out. The result is about 3/8" prop clearance.

Here is a couple more shots to maybe show horseshoe better

I added a radial dummy from FTE and did up the cockpit with a sliding canopy. Thought you might like to see these.
The dummy took quite a bit of grinding to make fit!

see you soon,
John

Here is a short video of the DA 100I on the test stand

https://youtu.be/CuNJXw1b0lg We have since got one flight on the plane. Great power, mostly half throttle. Sounds good in the air. Unfortunately, I bent one of the trunions on the retracts on landing. I hit a rut on roll out.

see you soon,

Great work John, the Jug looks fantastic. If you want a really nice looking dummy radial that takes a lot less grinding give Scale Specialties a try next time. They have the best dummy radials in my opinion and the crank case is hollow cast which makes it much simpler to fit around your engine.

They make the nicest static props as well.

Thank you John really appreciate it, looks good. Did you leave the back open on the bottom for air flow? Can you post a pic of the cowl cut outs for the exhaust and air flow? Where did you get the radio tray box that you used to mount the ignitions and battery in?

Thx

Hi Clover Creek
i just purchased Snafu. Where did you get your cockpit details?

My Feedback: (198)

That looks like I Fly Tallies cockpit. I have the same in mine. It is a little large of the Robart but works. Robart is smaller than 1/5 scale.

clover creek

You are correct sir!

Hi all,
I just put a deposit on the Snafu! I am very excited! dose anyone have any good tips on build.
Thanks,Vincent

clover creek

Yes, I exposed the cylinder and exhaust. There are no cutouts in the cowl. By moving the cowl forward, I created an exit at that point. I opened the scale exhaust area plus all the vents throughout the fuselage. Also quite a bit of air flows through the rudder post. So far, no issues with overheating. Maybe when it warms up I'll drill holes in the black checkers on the bottom of the cowl.
I could also increase the size of the holes the exhaust protrude through.
Regarding the box for the ignitions, it came with the kit. Since the picture, I have added a choke servo.
Hope this helps.

see you soon,
John

Thanks John, I follow you. I was not aware the kit came with the radio box/tray.

I don't know if this problem is isolated to my plane alone.
On mine, when mounting the wings, there are no stops inside the wing to center the wing tubes. We noticed this the first time we dry fitted the wings.
My solution was pretty simple. After careful measuring, I fitted a plywood ring to the tubes then, routed out the rib on the fuselage to accept the ring.

Anyone else have this problem?

see you soon,
john

John, I just checked mine by looking down the wing tube hole with a flashlight on each wing. Yes mine is the same, the tubes in each wing half have no stops on them. Good point.

Hi Vince,
I also bought SNAFU, and I'm also putting a DA 100 In line in mine. I hope mine turns out as nice as John's.
I'm doing a build thread over on RCSB if anyone's interested. Here's a link: LINKY

Hi Drice45...
Sorry for your loss in "Miss Behave". Awsome that you are building the Snafu! Thanks for sharing the link to your build thread. Looking forward in following the Thread!
Thanks,Vincent

John , ground clearance may be an issue with that 28-10.

Yeah i was wondering my self about that..How much prop clearances is there?
Thanks,Vincent

Mine has a DA-85 wit a 26-10 and have torn up the tips if I'm not careful.
