I see, well that is normal for all these cars. You have to find ways to adapt the driver. Check past build threads to see how people do it. IM do a flattered body which can be added to full legs..... Andi
Short of using a FF030 (Solarbotics) or using a flat tray, or could use the Mashima motor Chris uses, I find this difficult to overcome. I tend to use a stepped tray. At least I can fit a full steering wheel, dash and torso from the arms/shoulders up this way, though, there a many many great builds that have used the flat tray in the cockpit area that look fantastic. I Dont like to drop the tray enough to include the legs as they tend to mess with body float, rubbing on the motor wires. Not so much because of the legs but because of the tray, in this case, the tray is needed so the chassis cant be seen from above because of the proxy ruling. I have been able to use a low lying body but it is very thin around the mid torso where it crosses the motor and the car body is sitting up high, something I dont like to do. I guess that question of built to race or built to show can be a thin line to tread when deciding which way to lean as we all try to get a little of both in the build. What this build for John?

Hi John, that's why I use mini motors.
Try one of these, it even has a gear that will mesh with most available gears, and carbon brushes. Not very high reving, but lots of torque. same dimentions as usual, but much shorter. Gear it less than 3 - 1.

This kind of relates to an earlier post on an earlier thread. The FF030 motors are racing wise pretty pathetic is power is of the essence. The proposed pioneer Hurricane was something I looked forward to of a similar size, but I gave up asking Jules about the avail availability of them. Space vs power is the name of the game these days.
Didn't Mark and a few others get a prototype Hurricane?
I love the solarsbotics and think it is a perfect choice for the bantam weight cars of the 1.5 GP class and 64',65 Tasman class, all things being equal. However, it fell out of favor because of its unreliability and lack of brakes and there was a large variation in RPM from one motor to the next. It was a steep learning curve to get used to its different characteristics when racing along side the 050 motored cars which had much better braking so it wasnt really suited to proxy format. Still, they are cheap enough to grab a few, and the slower RPM motors could be well suited to the cars spending life on the shelf Solarbotics was legal for VRAA a few years ago and was legal for the Tasman up until this years event and is no longer legal either.
Chris's suggested motor above looks interesting and would be keen to learn how high a gearing it can handle? The Solarbotics is happily geared at 3:1. A certain solarbotic powered Tasman entry from a few years ago accidentally geared at 2.6:1 went like a 'rat up a drain pipe' while the motor was fresh but the car required 2 motor transplants over the 7 races! So The above motor might be a good alternative. Would be keen to hear follow up on this one...

Not a lot I can add on this. With any FF050 type motor in a 1.5L car its going involve serious surgery on the driver. As a piece of fairly useless information I bought five small (a bit less than 030 size) motors from Ranch Design a few years ago.
I put one a Beardog chassis in a Lotus 25 and it works very well - the performance is very good (as good as an FF050) and it enables most of a driver figure to fit. Of course Ranch Design is no longer in business - much missed - but I think its the same motor as this - www.radioshack.com/products/radioshack-9vdc-micro-super-high-speed-motor . Chris tells me Radio Shack went out of business some years ago but it appears their stuff is still available as long as you live in the USA as they don't seem to deliver internationally. I did say what I could add was limited and fairly useless!!
