Almost finishing my build. Was wondering if anyone did a similar setup as mine: Futaba 9550 laid down.

I hear ya... those front and rear 2009 wings from Tech racing should look really cool with the new bodywork....


... and the new front with should help with counteracting the car's front push...

will the F103 front and rear wheels fit the F104? I have seen a local shop that has the premounted Tamiya foams going at less than half price

Dude, that might be it. Those links are way forward. which should get some more steering into the car (less ackerman). Now I gotta redo my car...

Well done, can't wait to get mine and do the same.

I think a lot of the reason the batteries have been run down the middle is to make a more realistic representation of the newer 1:1 cars which are much narrower.
You might be right RobK, but let us not forget the CRC F-1 from the mid 90's that made the F103 obsolete, at least on carpet. Anyway it sure will be fun to see how well the car works in the Hurricane series. ( If the larger size rims are allowed.)

Default F103 premounts: yea and nay

If you've got an LHS selling the premounts off cheaply, grab them. They're good for the F103, esp. if you run the car on a high grip surface. If a low-grip track, use a softer T-plate and a soft rear suspension setting. As for whether they'll fit the F104, the rears will definitely fit (F104 rear parts are interchangeable with the F103), but will lower the rear ride height and you must compensate. I would be concerned, however, with not using the tires/wheels the F104 is meant to use. These new rims are bigger and will accept any 10th-scale foam donuts you can find, so we will have some significant options as to tire selection, especially as the aftermarket cranks up. For the front, although the F103 rims/bearings will fit the F104 spindles, the wheels do not clear the F104 kingpin. Perhaps you could change in an F103 kingpin so the wheel would fit.
I'm interested in the reverse issue; we'll be able to use F104 rims on an F103; when the tires are too worn (low) to be useful on the F104, they should be coming right into perfection for an F103. Will test this at Tamiya's track as soon as I have some tires that are worn enough to fit the F103 practically.

i also like the sculpted sidepods. im just concerned over 2 things...

-will the sculpted sidepods clear my preferred electronics setup and transponder without making the body warp like the ones on the F-103... (unless you put insanely small electronics on it...)

-will those sidepods and other aero bits fall off in a collision like some of the aero bits on the Chevron F1.08 body set?



and im not sure if this question was answered before... but here goes...

will F-103 bodies fit on the F-104? i got quite a few bnew F-103 bodies that have never been painted yet and now i feel that the 104 made the 103 obsolete... now im planning to convert my 103RM into a 103GT...

I'm pretty sure the F104 OEM rims should be legal. The concern is 1/10 pan car wheels/tires.

Default F104 1st take

I did run the car today on an asphalt parking lot track. The rest of the field was F103s of various configurations.

One thing I did notice off the bat was that the car was somewhat sensitive to bumps. There were some cracks in the lot, one specifically in the straight, that did upset the car. Looking at the way the t bar pivots are set up, the 103 is softer front to back than the 104. My car seemed to skip and bounce over stuff more than the other cars. I even went to the soft T bar, but it was still sort of stiff front to back.

The car did turn hard off center. It was a little nervous, even after putting 60K diff oil on the front pins and going to a black front spring. The key will be to find the way to hit the sweet spot between turn in and push and turn in and get loose. Part of this might also be tires.

I wound up driving the car with the throttle more than the steering wheel. It seemed to take a bit more throttle modulation than I was used to.

Overall, pretty good. Right now I'm not sure if tires would be a big help or not. It is tougher to drive than the 103. This week I might be able to try it on carpet, maybe that will be it's forte.

The rear should fit but be careful of the front wing, I've been told some the f103 wings sit too close to the front tyres.

Default Stand up servo mounting

The instructions say as long as the servo measures 30mm from chassis to the center of the servo gear, it will work. I measured my Airtronics servo (94358) with ears cut off ( can't believe I had to cut them off ). To get it to 30mm from the chassis up, there will be a gap underneath. should I fill the gap under the servo with servo tape to make it 30mm or should I let it sit down on the chassis with a measurement of 28.35mm? What would this affect?

Saw this setup on a F103 some time back, and since I got the F104 and the 9550 in my pitbox, I thought I try it on the assembly.

The Turnbuckles didn't touch the upper arms at all. Think the bumpsteer is minimised, though it cannot be removed completely. I can't wait to get the tires glued and run it for the first time.

May have to cut a little more on the lexan body for the turnbuckles to clear. By the way, I'm not going to use the plastic battery retainer as instructed in the manual. I have found some Tamiya thing to fit in place.

Do post your reviews, if you have run in similar setup like mine.
Thanks in advance!
Alfie
