jh2rc97,

Very nice looking BOT. I have been considering getting this kit. Is the bolt on wing an option with the kit or is it your own design?

The bolt on wing is a mod that I did. It is not shown as an option and there are many ways to do it. My idea was to only use two bolts to hold the wing on.

That's a very innovative design. I prefer a only two bolts to hold the wing on as well. Do you have any more pictures of your wing bolt setup during construction and what material did you use for the mod?

I ordered a BOT today. I'm looking forward to the build.

I did not take any pictures of the wing during that part of the build. The tabs are 1/8" ply (5 layer) near the leading edge and 1/16" ply near the trailing edge. Scraps of balsa were also used to block up the tabs to the correct height.

I noticed the plug in the root rib. For spoiler servos? What kind of plug did you use and how did you fasten it to the wing structure?

The plug at the root is for the spoilers. The idea was to only have one cable to plugin while bolting the wing on. I used 3-pin Deans connectors. Deans connectors are a tight fit so it is a good idea to plug and un-plug the pair you plan on using several times to get them to be alittle less tight. To get them lined up I get everything but the top sheeting on the center section of the wing done and side the halves together. Then I use alot of epoxy to hold them to the root rib and to the bottom sheeting.

One thing that I am worried about is the reports of the 1100mAh A123s failing open. I know the 2300s fail shorted which may push me towards using the 2300s. I have a CC PHX45 laying around but might get a PHX35 for this. I am thinking I will use Hitec HS82s for the elevator and rudder. For the spoilers I am thinking of an HS55 in each wing. I will be replacing the spars for CF and balsa spars. The wing will be bolt-on instead of rubber banded. For a radio I will use XPS 8 channel receiver and CC-BEC to power the receiver and servos. Or at least thatís the plan as of right now.
What size prop are you using?

In this thead, I looked for a flight report... didn't find one, but sometimes I am not so sharp.

I just received my BOT, the ARF from Tower Hobbies. I couldn't turn down that $129 price together with a $15 discount(On a $150 order.) And I have that same Eflite 480 that yoiu used... which I would love to use in this plane but I was worried that it might not be quite strong enough.

What was your opinion on this motor utilization?

In about 5-10 mph winds I also think a little ballast might be a good thing.

Here is the report of the first few flights. Since then I have not had a chance to get it back in the air. Hopefully it will warm up here soon.

Hi, I have 2 BOTs. One in the box (in kit form) and the 2nd one is a ARF, No test flight yet.

I too am looking for info on installing spoilers on the arf as well as on the kit.

Thank you
