    Question Trying to Identify this boat

    My uncle recently handed down to me an old nitro RC boat and i am trying to identity what it is and what i would need to restore it. I remember this thing zipping around as a child and i would love nothing more than to put it back together and make it go again. Here are some pictures of the boat and the insides of it. Its just the body and nothing else so i know i am going to have my work cut out for me and any help would be greatly appreciated.

    So after a few very long phone calls and some research i found out that this boat is a Dumas Drag n' Fly 40. I want to put an engine back in this thing but i feel like i am way over my head on this endeavor. I want to end up restoring this thing back to its old condition without putting a bunch of newer stuff in it. Can somebody point me in the right direction for stuff to look for on eBay and other websites. I want this thing to have an old engine in it like it had back in the day and i just have no idea where to start. What size and type of engine was this boat designed to have in it, what else do i need in addition to the motor to make this thing work? Can anybody offer me any help or suggestions or want to guru me through this project?

    Back in its day a lot of them ran a K&B Sport .40 engine. It was inexpensive as you could get one for around $70.00. K&B doesn't make it anymore. Dumas Products may possibly still make the running hardware for it. I don't see a lot of old-school engines for it on eBay in the size you'd need. Decent .45's nowadays aren't cheap.

    Are the K&B .40 engines that i am seeing on eBay the same for boats and planes? or are they different?

    No. The timing is different and they should have a water-cooled head.

    I have a spare K&B sport 40 setting I'll never use it, just looked its NIB with a muffler. It has a carb throttle and a exhaust throttle.-guess that never took off over kill .I can add it to the for sale section if interested. Just to point out a K&B SPORT 40 is a sport engine not a racing engine.They run all day long. Nice looking Dumas hull, must of had a set of wings in them rear slots.

    The carb arm is attached to the choke throttle via that spring

    I found a Parry carb to fit the Russian engine. The K$B engine I have a normal cable coupler for .187 cable. Russian engine has the dog bone setup.
