G'Day everyone from Australia
I have been tinkering on and off for the last few years with a Drag Rail
All the designs came from my own twisted mind
K&S 3/8" brass tube chassis/silver soldered
(empty chassis weighs the same as a 1/10 nitro on road car)
Junior Go-Kart front wheels are my rear wheels
Stainless steel steam pipe rear axle
Stainless 7/16" tube drop axle - front (this came from a beer brewery) Hmmmmmmm, beer!
Hi - Tec 1/4 scale servos
1/8" stainless TIG rods for linkages
Aggressor FM 3 Ch radio
3rd channel runs a Hi-Tec sail winch - this pulls a velcro strap that will deploy the chute
Parachute? a golf umbrella with polyester cords
Stainless steel 3 oz. hip flask for the fuel tank
poulon 44 cc chainsaw engine (modified, of course!)
35 ASA chain drive
10 tooth steel gear at clutch bell
20 tooth to 10 tooth splitter transmission all lightened industrial gears
36 tooth steel rear sprocket
Rear sprocket doubles as the disc brake
Caliper is from an Industrial Strapping Machine's strap Dispenser (Cyklop)
5mm alloy checker plate floor
Duratrax failsafe
front steering/geometry is all hand made/self straightening
front wheels - came from an electric scooter called a "techno"
front rims - 2 piece alloy (modified & balanced)
Front steering rods + himey bars = 3/16" stainless tube with 4mm steel joints
Pipe is custom made from lithographic plates (thin aluminium) all bonded with plasterer's tape and Devcon
-- this should give me 16,000 RPM
chainsaws normally get to 8,000 RPM, so it's going to be a "grenade" engine!!!
rear wing will be made from carbon fibre arrow shafts + sheet aluminium
body will be made from 0.8mm polycarb sheet
It's on hold at the moment, cos I just got a 44" boat to play with!
O.S 0.61 Nitro powered 4 lb.hull - fun fun fun!!!
