I'm using a 2200 mah and worked my way from 10mm in front of the step to right at the step. I tried one flight at the recommended CG and didn't like it at all. Much faster take off and easy to hold high alpha but it didn't seem as tail heavy as in the video. Maybe because of the heavier battery and using lower rates.

I'm pretty happy with a CG right at the step.

I've been looking through the hobby king site trying to find a match and also sent a note to support. I'll try my local shop tomorrow to try and find a match. I better get some spares because I have a feeling this will be an ongoing issue for me with water planes.

I picked up a couple of Park zone SV80s for the ailerons from the local shop. After waiting 28 days for the Skipper I wasn't going to wait another month for replacement servos.

Easy to replace. Only one of them went bad but I replaced the set just in case. There was plenty of water inside under the servos. So better keep the skipper pointing up while it dries.

I did make a video for hobby king support to see. The servo works but only moves in one direction.

Probably better to waterproof the servos with something like this:

Rust-Oleum NeverWet tested on R-C equipment to the extreme and more, by NightFlyyer. (11 min 39 sec)


Check around 6:30. Pretty impressive.

A careful check on the product specs reveals a warning that it is NOT for use on electronics. This quick dip and water dropplet demo does not show the long term effects of the product on electronic components and PC boards.

Better stick to CorrosionX.

Why does rain stop you? it's a water plane Seriously though, I use a motor home with an awning when I go flying, the last time I was up at the club field there were quite a few heavy showers. Instead of stopping flying I stood under the awning and sent the Dragonfly/Skipper out there

Following one of my world famous stupid pilot tricks my Skipper ended up floating about inverted for a while a couple of days ago. After being rescued, drained and thoroughly checked I set about flying again but all was not right. The rudder servo took on a mind of it's own. Sometimes it would work OK, other times it would slowly offset about 1/3 deflection in one direction while still otherwise responding to rudder inputs. That made for an interesting but safe landing. I don't look forward to replacing that servo. Glad it wasn't the elevator servo, but now I've lost confidence in all of the so-called "waterproof" servos this thing came with. Oh well, I'll fix what's broke and fly 'till it's broke again.

Ok guys I am still out at the lake flying but thought I would let you know my cut down 7x5 prop works great. Gets on the step much better and pulls up off the water real nice now.

huh? Please refer to post 226. No problems what so ever I have the cg set right on the step.


Guys Im putting the stock motor back on till my other stuff arrives. I ordered it 5 days ago and HK still hasnt processed it.

I changed the motor wires for some heavier gauge to handle the new motor. The stock motor is 2100kv if you guys were wondering. I'll post pics later on how I fished the wires threw the vert stab. Have to run. Doing Remembrance day dinner and Im late

Ted, same here. Since I replaced the aileron servos, I haven't been flying the skipper from water. Wet grass in the mornings before the wind comes up. It flies so nice when there is no wind but that tail wag gets annoying with the slightest of wind even at high speed and with a gyro.

Pls send a note to Hobby King on the waterproof servos. I currently have case open with them and waiting for resolution before i fly from water.
