Status: offline 		I gave a call to DA-100 and spoke to Bill. We could shorten the 12'' stock headers by 1-1/2'' maximum without any difference on the RPM or throtle response. The most important thing is to cut both headers at the same lenght.
For the Giles, you need to cut by 3/4'' the headers to fit in the canister tunel.

Status: offline 		Ok
I made the first CG balance test and i need to put the A123 batteries in the tail. Not a problem but when i mounted the cowl, i used only two screws...

Questions
1) Is it a problem to use only two screws for the cowl? The two other screws are not accessible with a screw driver?

2) Should i cut the cowl to make bigger exit air under the cowl or we could simply use the cowl design to cool the engine?

Status: offline 		Scoubidou,
I've been running with only two screws on my cowl and no problem. But After about eight flights the cowl ring came loose on the bottom. Just the cowl ring to cowl joint. I was able to reset it with Zap a Dap a Goo and no problems since, the lower retaining hooks are doing a good job.

I also have the DA100 but with stock mufflers. I put baffles in the cowl openings to direst air over the heads and this engine is running cooler than any I've run before. So I'd say don't hack up the cowl, the holes back by your headers will aid the cooling and you should be fine.

Status: offline 		The cowl is held securely at the bottom by the ply "hooks" and is meant to be used with only two screws. The screws on the bottom are there in case one is forced to cut out the original retention system, it seemed like a good idea at the time but it''s never been used by anybody.

The air exit at the bottom rear of the cowl is usually sufficient, and with the canister vents cut out there is plenty of exhaust area.

Adding baffling is always an option if done properly, it must direct air to flow over the cylinders. I tend to want to test things before adding anything, I find that some people add a bunch of stuff to planes to solve imagined problems that do not actually exist.

Thanks for the explanation on the hooks Tom, that makes sense. I just couldn''t see it hanging from the top two screws without any kind of bottom support.

Status: offline 		So what is the length exactly? This post says 92 and The wild hare web site says 100". Also I was wondering about the power and balance with a DA 85. Is it designed around an 85 or does an 85 just work? I live at 5300' and density runs about 7500' in the summertime. I have a 3W 106 but I am afraid for the weight factor in this plane. I am considering either the DA 85 or 100.

The plane standing on its nose will just clear an 8 foot high ceiling, makingt it just under 96".

The new Giles G202 was designed before the 85 came out but I had a lighter engine in mind when setting the plane up, that's why it comes out a little nose heavy with a 100cc twin.

However, with the altitude and the power of the 106 I'd say that your engine is ideal. Wing area is not an issue, the wings are huge and you will have plenty of lift, I would be more concerned with power at your altitude and the 106 is the top of the heap in that group.

It's always a quandary working at altitude, what's more important lower weight or more power. The perfect solution was the BME 110/115, which is really what I had in mind when I was designing the plane, but that engine's availability is suspect. I'd say use the one you have, it costs nothing. You can always change later if you're not real happy.

Status: offline 		I flew Bashedit's Giles and at the time it had a 3w 106 in it. The plane flew very light and precise and as far as weight and power goes it's very excellent. Reliability of that particular 3w was not good it had more than a couple dead sticks with the motor but if your past that issue you'll love the plane with a 3w 106 or da 100.

The video of the giles on the wild hare web site is the plane bashed it assembled and i flew with a with a 3w 106.
