3S 20" "Kneeler" Hydroplanes

Jerry Dunlap · Feb 12, 2016

I saw these outboard engines on the Hobby King website and had to have one or two. They are 3000 Kv and with a 3S Lipo are probably pushing the 20" WOF boats close to 40. The prop is a metal X432 copy(imagine that

). I now have 3 of these "Kneelers" RTR at our club events. JD's Rent a Kneeler.

I've found this one to be better than the one that has "MERC" on the cowling. This unit has more power, 3000Kv compared to 2650 Kv, a water pickup on the cav plate, and a better flex drive set up.

This not the unit I recommend. It does look really cool, but the bend for the flex cable drive is too sharp, the motor mount has too be modified, and it is not as powerful.

JD I see some complaints on getting spare flex shafts on line. Have you picked up any spares and if so your source please.

I have tried making flex shafts for for the "MERC" version and need to improve my soldering skill for attaching the the stub shaft to the flex shaft.

I have not had an issue breaking a flex shaft(Yet) with motor I recommend in post #5. I can also make flex shaft for this motor.

Any plans available for the kneelers JD ?

I want to build or buy one to small pond play with . Makes tossing a fun boat to run into a smaller pond VERY easy.

I will start working on plans next week. BTW - I ran the "MERC" version today with a flex cable drive I soldered up. It held up for the 4 minutes I ran the boat.

Jerry--If you've never been there you need to check out the 152vo website from Germany The fellows there have taken up building and racing 1/5.2 scale OB racers from the 40s and 50s here in the states. I ordered and built the first SwizerCraft Baby Bullet kit sent to the USA. Dave Richardson(RPM Rod fame) and Rod Geraghty have also been into these models recently. I have a YouTube video at g ray hamby of my BB running and hopefully can get some interest in a new fun class for us oldtimers to enjoy. grayddsView attachment 69604

I have seen the website from Germany. Amazing detail. Rod has sent me pictures of his boats/engines. I'm looking forward to racing my boats on Saturday, March 5.
