I will just buy a new trailer. I am sure that it will be comfortable to sleep in when my wife finds out!
Would you be able to build a bigger box for your existing trailer

The first trailer was to get my wife used to the idea. What I really want is a trailer large enough to hold my 35% and 33% plane. Building a bigger box on such a small utility trailer would be problematic.

Motor and ESC Mount

I calculated that the motor needed to be mounted 5" out from the existing firewall. I decided that the easiest way to do this was to build a box out of 1/2" plywood. The top and bottom are open except for some gussets made out of 1/4" plywood. I drilled some lightening holes. I used 60 minute epoxy and wood screws to hold it together. The box was 300g (10.5 oz). The motor mounts to the front of the box using 6 mm bolts. The X-base on the back of the motor is threaded. 1/4-20 blind nuts and bolts to hold the box to the firewall. This seems really sturdy!

I mounted the Jeti speed controller under the motor at an angle to catch a bit more air across the heat sink. I used some small motor standoffs to hold it to the fuselage.

Hacker A200-8

Geoff,

I like your build. I plan on installing the Hacker A200-8 in my H9 46% Ultimate so I am watching your build closely.

35% 260 electric

Geoff,

I heard from a friend that you were doing this setup and i figured i might be able to give you some pointers on it being that i have almost the exact same setup as you are planning on doing.

First, i must say that this setup is awesome and works great. It has tons of power and flys the plane great. Mine weighs around 29 pounds but feals like your flying a foamy because of the power, its almost too much sometimes.

The main difference i see between our setups is that i went with a Jeti 170 amp speed control, thunder power 5000mah 6 cell packs, and i am running a mejzlik 27x12 thin prop. This is the setup that hacker recommended to us.

We have no ducting on it but we run no spinner to allow the air to pass over the motor better. It stays cool even through a hard 3D flight. Our motor is mounted on a milled and lightened round piece of delrin plastic.

The only downfall i see to this setup is the flight time. I can only fly for 5 minutes. When flying IMAC, i have to repack between sequences only flying intermediate, it would not make it through an entire advanced or unlimited sequence Other than that i love it.

We liked the giant scale electrics so much that we decided to build two 39% krill katanas with pletenburg motors for freestyle. Cant wait to see how these go.

Thanks Kyle.

Is this really your first post?

Someone quoted your setup which is why I decided to go with the 5800 mAh batteries. I was looking at my 4.5" spinner in front of the motor thinking that it may mess up the cooling. Plettenberg has a spinner for their motors with a hole in the middle. Someone needs to come up with a simiilar product that will work on other motors. What do you mean by "ducting"?

Yes this is really my first post, im just starting to post on all these flying sites.

It definately needs more capacity battery wise to get longer flight time, its kinda discouraging when you have that unique of a plane and can only fly it for 5 minutes.

We saw a big change in temperature just by taking off the spinner, it would be very difficult to have a system like pletenburgs with the spinner setup because their motor is actually in the spinner, not behind a prop like the hacker is. I meant to say baffling rather than ducting.

Geoff, I like the look of a spinner on my planes and if you are worried about air flow, get a carbon fiber spinner (the kind that has the screws around the base) and cut the nose off to allow air to funnel in. It (the spinner) would have the same look as the Plett spinners.

Hey Geoff,
It looks like your making progress, I thought I would post some pictures of my setup.
Hacker A100-8
Jeti spin 200
Vess 26b prop
Zippy 6s 5000mAh 30c lipo's (12s2p)
146amps/42v /7200rpm/6132watts
10min flight / 7min motor run / 3400mAh per pack /pack 95deg. / motor 76deg.
Im using JR DS8711 on all serfaces (1 per Aileron)


The plane is 27lb with batterys
I have about 60 + flights on the plane (IMAC / 3D) it has a ton of power and is the best plane I have owen to date, I like your choice of battery size (5800mAh)

Welcome to RCGroups!

I have noticed that the motor in my Sukhoi gets warm. I did not think that the spinner would make much difference in cooling but I guess that the shape does create quite a wind shadow.

Cutting the spinner is a great idea but I wonder if it would result in the spinner flying apart. It might require some reinforcement around the leading edge.

Thanks for sharing BSIPRO. I was hoping that you would post some pictures. There seems to be a few of us using the Hacker / Jeti combination.

It would seem that you are not having any issues with the motor heating up behind that big spinner.

Canopy and Firewall

Finally the correct windscreen arrived from Horizon late last week. As you may recall the original one was damaged and they sent three wrong ones that looked to be from the 46% Ultimate.

I have always found it a pain to glue the windscreen to the canopy. They never seem to fit exactly right. I cut away the covering on the glue joint and used canopy glue. I used lots of masking tape and weights but I had to re-glue a couple of areas that did not adhere completely.

I make it a habit to paint the firewall flat black to make it less obvious from looking from the front. Not as important on an Extra but it makes it look a little tidier on a round cowl plane like a Yak or Sukhoi.
