I'm enjoying the Spit pics.
I was down in Minneapolis last week, Hobby Warehouse had the giant TF Spit on the shelf, shop owner Tom says its $600.00. http://www.myhobbywarehouse.com/

I just received the retracts and wanted to install them but it turned out that one of them is not working at all. It seems like worm drive is not moving and probably the motor is shutting down because it is blocked. Anybody have an idea about how to fix this? Should I risk loosing warranty and open it up? I must say that I am really disappointed with Robart electrics, I have another set in a corsair and it caused quite a few problems, too.

Hi,

I've always thought Robart electrics are a bad solution in search of an imaginary problem. Plumb those air retracts correctly, and they work season after season.

There is/was a problem with the robart electrics. If you switch on power to the gear a few time without cycling the gear the motor keeps jogging the lead screw tighter and tighter each time until the motor cannot run the lead screw in the other direction without hitting the current limit. You can manually turn the screw just a little and it will free itself. I don't think you need to disassemble everything.

I am sure I could have fixed it but I didn't bother just sent them back. I have ordered the pneumatic version from tower. Shipping and customs charges will be added but I also think that electric are less reliable. @Shaun, did you actually use the HK Spit retracts? How did they work out?

Hi,

To be honest, I can't remember?

I have acquired one of these Top Flite Spitfires.
The plane was not really even close to finished, so still a good amount left for me to do.
It did have a 60cc Gasser on the front, but one of the four prop bolts was broken down to 1/2" sticking out from the prop driver on the front of the motor.
I'm unable to remove that to try and replace it(must have had a ton of locktite put on it).. So, considering that only 3 bolts would hold the prop on, and probably the broken 4th one might cause an unbalanced vibration problem, I removed that motor from the firewall.

I have decided to convert this aircraft to electric.
Does anyone have pictures of how they did a battery hatch?
I'm leaning towards putting the batteries right behind the firewall.... Sitting straight up. This places them under the back end of the cowl.
Two 6s 5000 packs...if I can, allow enough space for maybe 6000 mah 6s for a bit more flight time later on.
The motor I'm planning on is a 50cc rimfire with a 22x10 prop. I have the white spinner that came with the plane(2 blade) as well as a black 3 blade.

So, how has anyone done battery placement on this plane for a conversion??

By the way, the plane has pneumatic retracts installed in the wing halves already. They are the Vantex(hobbyking) gear that was sold for the Vantex 89" spitfire still for sale at Hobbyease.com. Last I checked, they had the retracts for sale at 40% off... About $95.
Oh.... And the fuselage has had the stock plastic covering removed and solartex applied in its place.
I'll have to paint the plane.
The wheels I have bought are the Robart Spitfire aluminum hub set.

This is the installation I've done using the hobbyking tailwheel unit. To mount it, I used the metal bracket from the stock TF tail unit, removed it, then conjoined it two hardwood plates sandwiched and supported by two square dowel rods.
It's controlled by a separate servo than the rudder.
