Airplane Boat Model do all rc engines fit on all chasis?
i have a k&b model engine, it was made for an rc airplane or an rc boat, but can i put it into a car chasis, and if i can, can i just buy any old rc buggy chasis and put the engine on it, or do i have to buy a certain one , or have one custom made?
You cannot just put any engine onto any chassis. There are certain size engines for certain size chassis. The engines are sized just for that. Having said that, it might be possible to mount it if the mounting ears, and the crankcase are of a similar size to the proper engine for the car. The only other issues you might encounter is if the output shaft is compatible with the clutch setup for the particular chassis you are using, and if the particular car's throttle linkage will mate up with the engine's carburetor. If these work out to be not an issue, then it might work.

Angles of Elevation and Depression?
(Round answers to the nearest unit.)
1) The angle of elevation from a boat to the top of a lighthouse is 35 degrees. The lighthouse is 96 ft. tall. How far from the base of the lighthouse is the boat?
2) Ming launched a model rocket from 20 m away. The rocket traveled straight up. Ming saw it peak at an angle of 70 degrees. If she is 1.5 m tall, how high did the rocket fly?
3) An airplane is flying 2.5 mi above the ground. If the pilot must begin a 3 degree descent to an airport runway at the altitude, how far is the airplane from the beginning of the runway (in ground distance)?
Problem #1 ------------
tan(angle) = opposite side/adjacent side tan(35) = 96/x x = 96/tan(35) x = 96/0.7002 x = 137.1
Therefore, the base of the lighthouse is 137.1 meters from the boat.
Problem #2 ------------
One slight complication to this problem is that the line-of-sight (and thus the triangle used to solve the problem) is raised 1.5 meters above the ground. Therefore, when we solve the triangle for the height component (x), we will need to add 1.5 meters to get the full height from the ground.
tan(70) = x/20 tan(70)*20 = x 2.747*20 = x 54.94955 = x
Now solve for the full height of the rocket:
height of rocket = x + 1.5 height of rocket = 54.9 + 1.5 height of rocket = 56.4
Problem #3 ------------
tan(3) = 2.5/x x = 2.5/tan(3) x = 2.5/0.05241 x = 47.7
The airplane is 47.7 miles from the beginning of the runway.
