Using wooden dowels as I have done before, the mounting screws need to be checked after a few flights as with vibration & such the wood will compress enough that you may need to snug them up again. Hope this helps.

Looks pretty sweet! Get that thing in the air asap!

I have never had that problem. I soaked the dowels with thin CA, plus I don't tighten them too tight. Many people crank the bolts down in an effort to keep the bolts from coming loose. This just crushes wood grains in the firewall, and possibly the dowel, which causes them to weaken over time, which makes them come loose.
I tighten mine just enough to make the engine secure, then I secure the head of the bolt with RTV(in this case at least - I usually drill the bolt head and use safetywire). I have planes that have been flying for over a year and have yet to have the bolts come loose. But I do check the bolts one time, after two or three flights, just in case...

Anybody have more pics yet?

Well, we had 2 Yaks flying yesterday without anyone taking pictures!! UGGG. Yesterday at TRCC we had a Yellow/Blue 100cc Yak and a Blue/White 50cc Yak flying around getting people dizzy! Jeff Sidelar put flight 3,4 and 5 on his new airplane with a DA 50 on it. It was flying like it was on rails!

Steve Clark was flying his 100cc DA powered one and was scarring the crap out of me testing the wings on it!!

Great flying by both pilots!

I got to fly both airplanes and they are impressive, this was the first time flying the 50cc and I was really surprised how much the 50cc plane flew like the 100cc one, very solid! The small plane really had a 'big plane' feel and it tracked on rails, this little plane will be an IMAC winner for sure for those just starting out in IMAC and the lower classes.

I heard your servos will go out today>> Cant beat the price on those guys. Are you running a power box or just simple single receiver?

AR9100, little spoon...
Got the tank and plumbing done - yippee.
Decided to use a Fiji 32oz bottle and make my own tank. Cheap and light, plus I'm not sure a 32 ounce dubro tank would fit without cutting that cross-beam out
