View Full Version : H-9 Clipped Wing Taylorcraft

I had one of these in the past with a Saito 180 that flew great, but sold it to a friend. When I saw one on RCU for sale that was assebled, but never flown, I had to have it. Since it was in Tucson and I live in Phoenix, it was no problem to drive down a pick it up. It needed a few things changed, so I searched and found a new cowl (the old one was cut for a Ryobi 31cc engine), windows (the old ones were painted black), windshield (old one was painted black) and landing gear (the old one was drilled out oversize and had oversized wheels/axles). I am still looking for the wheel pants and seat.

This T-Craft is rated at 13-15lbs, so I decided to try a new PJS 3D 10000 motor in it. Also used was an MGM 90amp speed controller and two Tanic 5c2p 7300mah with 15-20c wired in series. Hitec HS 635BB servos were used long with a 6v Ni-mh battery pack to run the servos. A Zinger 22x10 prop was used. PJS 20x12 and 24x10 carbon props have been ordered and will be used when they arrive. The finished weight of the aiplane is 16lbs.

After overcoming a few issues, the test flight yesterday was very successful. It flies great at 1/2 throttle and goes straight up at full throttle as long as I want.
Here are a few photos...

The final assembly has the speed controller located on the bottom of the firewall box, just behind and under the motor mount.

Very nice Jake! Have you measured the Watts/amperage yet?

Nice job! That really looks sweet!

Thanks guys!

The numbers are as follows:


The plane is a joy to fly and I am looking forward to taking it to the field again this Wednesday. Aerobatics to come then...

I think your watts are off a little
At 87 amps in to 4300 watts means that you would be running 49.4 volts
You say two 5S pack at a average 3.4 volts per cell uner a load would be 34 volts X 87 amps = 2950 watts.
Even at that you have about 184 watts per pound.

Hi Milton,

Thanks for your input. I'm in the middle of more testing and will post the results later.

I am now putting together a H-9 P-40 and will be using the PJS 3D 5000 with an MGM 90amp controller. Will post more info, specs & photos later.

What is the cost of the PJS 10000 and who has them

My PJS 3D 10000 motor is one of the first two imported to the USA. The other is being installed in a H-9 Cap 232. They will be available in about 2 weeks and you can get them for $299.00 plus shipping from Jake's Planes. (AZ residents must pay Uncle Sam!) Their website is under construction but will be up & running very soon.
