Default Mark: Question about Extra 30cc build

Do I leave the 30cc drill guide plate in front of the firewall and sandwich it between the stand-offs? The firewall look pretty thin on it's own. The DLE manual says "at least 3/8" thick for a firewall. I haven't measured but the firewall appears 1/4".

Steve,

The template is meant to be removed after the holes are drilled. The firewall is very strong at its current thickness.

Mark,

Just sent you a PM.

If I remove it, I am very far off from making the 6 1/2" firewall to prop hub distance. I would have to use 1/8" of washers (in addition to about 1/4" I already must use. I left it sandwiched between the stand-offs and the firewall. It's the same material as the firewall, right? It appeared to be ply. I then had to add about 1/4" of washers between the drill guide and the stand-offs.

In the manual, the photos don't appear to have any additional washers moving the engine forward. Did I do something wrong?

I'm flying the heck out of it!

I left the drill guide on sandwiched between the stand-offs and the firewall. I only had to add about 1/8" of washers behind the stand-offs.

Amazing flyer, btw.

So far so good! Other than the owner of a local shop here that "warned" me about them. He said "I'm not saying they're bad but just keep an eye on them". Of course, I didn't buy them from him so.....

Well I have got about 100 flights on the 50cc and about the same on 30cc and they have held up nicely. I have a bunch of the micro metal gear servos on a 1400mm Airfield T28 and its been steller as well. Good luck and take care....call if you need anything.
