Lawrie,

I used the engine mount that came with the kit. All in all, the arf had a lot of things that I liked about it. The firewall had a fiber glass cloth already glued into it for reinforcement. I did also re-glued certain high-stress areas, just in case....But I liked the fact that they it came like that from the factory. It saved me a trip to the hobby shop.

But it also had some things I didn't. For example, there's no way I could get 45 degrees of throw with the plastic control arms that came with the kit... I checked it out about 30 degrees. So I bought the Dubro arms and now I am at 45-50 degrees on high rates...That will come in handy to hold a hover. The arf also comes with a generic gas tank...Go put a Dubro 24 oz in it. you will be glad you did.

The instructions also said to glue the stabilizers in place. Well, I didn't. I drilled a hole through the aluminum stab and fitted 2 4-40 bolts and used medium ca to hold them in place. I have the same set-up on my Composite arf, and it works fine. Next I decided to go with the pull pull inside of the fuselage instead of the tail and you know what I think it's still tail heavy....I have to wait until the weather gets better so that I can try to trim it out again.

As far as the DZ.....Wow!!! That thing is a monster. I have a DA-100 on my Composite, but call me Crazy, but I like the 140 more only because it doesn't suck 2 oz per minute like my gasser does.
