My boys are not old enough for me to feel comfortable letting them start my engines... HOWEVER they do make fine dead stick landing plane retrievers I even have them trained to turn off the switch before they pick up the plane

There have been many on-board starters marketed over the last 30 years. The 2 main drawbacks they have shared have been Cost and Weight.

As you can see in the Hobby Lobby ad... Cost is substantial. They don't clearly show how much weight you are adding.

That 12 volt 700 mah pack is 12 AA NiCds. Weigh your TX battery and your RX battery combined...

The .40 size starter's motor is about the size of a common RC car motor. (add the weight of 3 more AA cells.)

Then you have the gears, and hte shaft and the couplers and the mounts...

24 oz is 1.5 lbs... THEN you add the mounting rails you had to put in the model. That much weight added to a .40 size airplane to start that .40 ci engine is significant. Some planes can handle it. (4*40) but you WILL see a performance change.

*******************

The cost is somewhat understandable.

They are short production run items. There just is not enough demand to get the economy of mass production.

They have some high strength gears and a one-way bearing and universal joints and the electronics to drive the glow plug and starter.... (A glow ignitor circuit is about $30...)

******

You can make your own... the hard part is the one-way bearing so the glow engine does not overspeed the starter motor and send pieces flying. Yo won't save any weight vs the one they are marketing. You might save $30 or $40. You will have a heck of a lot of headaches making it work.

I installed one in a large cub for a club mate.

He wanted it, so I did it.

But I'll agree with FHubber, that there is a significant weigh gain.

iI would like to install it on a Balsa USA 1/4 scale cub with a Satio twin 1.60 on floats. The suggested motor .90-1.20 I'd like to use the twin, anybody done it? Is this motor to big?

I think I will order one for my Big rascal. It has a 9lb payload capacity and a ST2300. Thanks for the website and info guys.
