Hello, I switched out the nitro engine for a 700 9.6 motor. I installed a solid 1/8 inch shaft slightly angled down with an Octura Y535 and the boat shot off from rest and planed instantly - now I'm impressed - it will be exciting to change out the motor and the prop... I didn't think 12 cells...

A 20" boat should get on plane without a problem. I don't have any experience with jet drives so I'm not sure what is required. It soulds like you're right about the rpm - maybe the jet is a little less efficient with moving water and requires a higher rpm. A stock Reedy or Trinity with ball...

Hi Ernest A 540 stock motor is quite low powered and very low rpm when compared with modifieds, but it should still have more torque than a regular 380 or 400 motor. A 380 or 400 may look impressive on paper with its high rpm per volt figures but it doesn't have the rotational force to spin a...

Thanks for all the help. I'm switching some things over right now. I think I'll use 12 cells - I'll have to experiment with their arrangement inside the hull. I have an Octura X640 that is not in use - what motor would go well with that setup?...I would prefer brushed for now because I also...

Hi, I've been very disappointed with my Miss Llumar nitro hydro. The engine screams away with an X432, X435, or Y535 but never gets on plane, just a lot of noise. The engine stalls at least once during every run - I've had Kyosho nitros before and never had a problem. Do you think I could get...

Hi, I thought this would be an interesting topic to start up... I've setup a lot of small to medium sized hulls for electric sport running but I have never tried a very large hull - like 40"+. Does anybody know of a good hull around this size? I would also prefer to have it already painted...

Thanks again for the help guys, I should be able to make everything work now. I made the mistake of trying to work with what I had on hand - I'll have to get some new stuff. I wish I could atttach a video of the vibrating flex coupler - its pretty scary. Hopefully everything else should be OK...

Thanks Guys, Its a little difficult to explain but the coupler itself has the flex cable in it. Graupner has a couple of couplers that are flexible (hobby-lobby website) They have a small solid area on both ends that contain the screws to attach to the motor and the flexible drive shaft leading...

Hey, I've recently converted a Proboat LLumar to run electric with a speed 700 motor. Everything is great except for one thing: my Graupner coupler (5mm to 4mm) wobbles excessively at high rpm, whipping back and forth inside the hull (travels about half inch side to side). Is there anything...

Hi, What options do I have to power a Dumas 7.5 Hull? I have a 3.5cc engine that I could use but I am unsure of the performance level I will achieve. How fast would a 3.5cc thunder tiger outboard push the big Dumas tunnel? I would rather use this now than buy a new outboard. Thanks, Greg

I have a couple of Graupner Electro Vees. One is powered by a Speed 700 on 12 cells, the other one is not complete yet. Is there any small (rc car sized) motor that will give reasonably speeds on 6 or 7 cells with a hull of that size? I understand that I will save the weight of an extra battery...

For Sale, Dumas Hot Shot Sprint 7.5cc ABS - hull only, with radio box. Paint job has been changed numerous times, and is only partially complete so it doesn't look good. I've got 4 other boats that I'm working on and I won't be able to afford a new powerplant for this hull - asking $150...

Thanks for all the help guys, Greg

Thanks, Ron I live near Kingston, Ontario (half way between Ottawa and Toronto) Greg

Hi, I've always been able to find tonnes of hardware and motors or engines for my boats, but I have trouble finding couplers to attach the motors to drive shafts. Right now, I'm trying to attach a nitro engine (Kyosho .16) to a Hughey 0.125 flex cable. What do I need to get this done? Thanks...
