It's hard to use water-based paint to paint the EPO kit.

Hope these would be helpful.

Chen,
What type of paint stick well to the EPO foam that you would recommend? Someone recommended an DupliColor Adhesion promoter for the water based paint.

I used WBPU (water based poly urethane) and the paint seems to stick really well. All I did was use some white filler to fill in the panel lines and some of the areas where the expanded beads had some gaps between and then sand the filler smooth. I then applied the first coat of WBPU and then sanded again. Another coat of WBPU and sanded again with finer paper. Then I gave it to my friend to paint with water based acrylics from Michael's (Apple Blossom paints, I think)

If I had to do it over again, I would have first cleaned the molded parts thoroughly with rubbing alcohol to remove any mold release. I have never used the adhesion promoter, so it might have been a good substitute for the WBPU. If that was the case, I would have done one more coat of the promoter after the final sanding.

The Adhesion Promoter is amazing on the EPO, but you will still want to clean the release agent from the foam with alcohol before applying the Adhesion Promoter. I have used the WBPU in the past. The Adhesion Promoter makes for a much better base for the water based paints. It is also much lighter than WBPU.

Water Based paints do work very well on EPO if the foam is first prepped.

Great for the heads up I use MinWax satin instead of the glossy, WBPU. I'll just use that before I paint. I use this to glass my planes as well with some fiber cloth but I don't think it's necessary hear.

Anyone have experience with GWS nano Retract Gear set on the 190? Does it fit or is it too small or big? What kind of servo was used? I saw somone else post they used retracts and they were a little too tall but not sure if these were the same ones.

Here are the measurements of what I have:

1 6/16" swastika

Could you measure yours to see if they are the same?

Thanks,
Kevin.

"Hey RCDad-

Anyone recommend a good motor for this bird w/o breaking the bank or swinging a large prop?

I would recommend a SUPPO 2217-08 from lightflightrc. It goes for about $19 and would swing a 10x5 or 6 prop.

• 70g Outrunner
• Kv: 1100, Rm: 0.125, io: 1.0A, Poles: 14
• Max amps: 18A for 60sec
• Shaft is 4.0 mm
• Dimensions: 27.5mm x 30mm

I'm using a Suppo 28-14-08 because I wanted a bigger motor for extra weight up front. The bigger motor is $27 and it is out of stock.


Good luck.
Kevin.

I have had very good results using The following combination:-

Motor http://www.unitedhobbies.com/unitedh...idproduct=6247
ESC http://www.unitedhobbies.com/unitedh...?idproduct=656
Batteryhttp://www.unitedhobbies.com/unitedh...idproduct=6293

The propeller I use is a GWS 10 X 8 HD. Thrust with this propeller was measured at 28.6oz with a static pitch speed of 51.8 mph.The current draw was 15.5 Amps. So an !800 mAh battery is enough to give 8-10 minutes flight including some part throttle flying for practice approaches.
