Use two 20mm spacers to get you to 40mm. Having the props at exactly 38.xxxx mm is not that important, you can always move the cowls a few mm forward.

Nice!. I will get some for my next project. I am already working on the motor spacers- I'll be making them out of wood

Na man, it needs to be back in Papa's hanger, papa is waiting for it to come back home for couple years now....it's needs alot more then just e-conversion, more like complete D Check.....

Here are some more recent pics

This looks to be about the right size for the motor

[Flyinbullmax]

What size of motor are these, and where do you intend to put your batteries
I think to put mines on top of the wing inside the fuselage

I have the TF DC3 with two 40 four strokes. It sure sounds neat on the fly by but you never know when one of them may quit. Attaching a piccy of a landing approach

Piccy? Where? Where?

But I hear you. That is how I have flown nitro twins as well. Always straining to hear every sound coming out the engines, always anticipating an engine out. But I LOVE the sound of twin nitro's!!

Electrics have changed all that. A lot more reliability in electric twins. Not that engine problems dont happen in twins, but are a lot less likely to happen.

On of the many reasons I am converting to electric.

Its the ST4010-820kv motor, which specs out at 850g Thrust, pulling 30A while throwing a 10x5 prop on a 4S battery. That seems like the right combination for this plane.

After working on the the motor mounts last night, I played around to see what I can do about ESC location.
I ordered 2 60A ESC's. I use these ESC's on my FPV planes so I took one out of my existing planes to see how I could make it fit in the Dak. Its obvious that the size of them doesn't give me any space in the wing near the nacelles. The best option IMO is to run the ESC's into the fuselage.
Its just as well. I was talking to Dangaras at the MAAC zone meeting about cooling and he suggested a fuselage cooling method using window screen mesh that is paintable and almost invisible. So the ESC's will be in the fuse.

I am a big fan of parallel battery setups, I have been using 2, 3 and 4 batteries in parallel my FPV planes with great success. This summer I flew my FPV Twin Kadet using 2 batteries in parallel feeding 2 ESC's through a single connector; It works great and I will probably do the same with the Dak

It looks to me like the batteries will be in the fuselage. I jut haven't figured out how I will gain access to them..yet..... Have you done your battery hatch yet?

[Flyinbullmax]

For batteries, I was thinking of backing the servo bay to the most aft and fit them inthere, it seems to be pretty centered on the cg too
still not decided.
Sorry for the poor drawing

Max,

I put my ESCs in the cowls, I don't subscribe to the"too long wires" hype. All of my multi engine models use the batteries in parallel. Even if the batteries are in the cowls I run a pair of wire through the wing to parallel the packs.

As for the battery hatch, you could carefully cut around the cockpit area making it a hatch held in place with a dowel in the front and magnets in the back. Build a battery tray and you are on the way to the maiden flight.
