The front section is detachable with pegs on the front and magnets on the rear.

The magnets will fit into the rear open section towards the rear of the opening.

Hi Tony, I hope you are enjoying the build young man.

I’m watching the motor installation with interest sir.

You have probably thought of this already, however can I make a one suggestion, in photo two of the engine installation it shows that you have had to cut away the tag on the tank box to fit the motor mount, this is quite a critical joint as it basically holds your motor to the airframe so it might be a good idea to epoxy two ¼ sq hardwood blocks ether side of the motor mount just to add a little strengthen back into the joint, I know there are three other tags holding the firewall to the tank box but you cant be to carful. I hope you don’t mind the suggestion, keep up the good work.

Hi mate. Yes it's a true joy to build. I haven't glued in the sliding motor mount box yet and already have 4 blocks to glue against the box and supporting formers to make it super strong hurry and get the 152 done as that is gonna be outstanding !!!

All the best

Tony

I thought you might have already thought of it mate but I just thought id mention it just in case you had missed it. I’m just waiting for the laser cutting to arrive for the Cessna so that I can crack on with the fuselage and the cutting jigs for the decking’s, the cowl plug only needs two coats of paint then I can start to make a mould but I wont be doing that till Monday.

Ok on with the Engine mount...as per what Richie recommended about strengthening the engine mount bulkhead where I cut....this was always in the plan.

And the magnets holding down the hatch.

And adding the cowl blocks on the bulkhead.

Servo's and snake's fitted.

This will be where the ESC is housed.....good ventilation from the cut engine bulkhead will give good airflow for cooling.

Not too much to do now....just fitting of the sliding engine mount and covering......wink

Ok here is my final bits and bobs done to my Hammerhead....wink

Opening up airflow to cool the 100a ESC.

The shaded area needs trimming away.

This should be enough cooling airflow for the ESC and Lipo...decided on 5s 4000mah smiley

I have thoroughly enjoyed this build...It's totally recommended for a noob like me...Now It's not perfect but I'm confident it will fly......and built by my own hand I'm sure it will be totally rewarding and feel different from building an out of the box ARTF or Foamie. I would recommend MaddogDesigns for someone looking to venture into their first traditional ish build.......It's been a learning curve for me and I'm pleased to report that it wasn't too steep !!! I have an Airsail Chipmunk waiting to be built and doing this has given me some confidence to attempt it and hopefully make it scale with loads of detail.

I'd like to thank Richie for his encouragement and also for designing a great kit...Thank you. wink

I will add more to this thread as I tweak "Maisie" for her first flight and will post a flight log and hopefully some video.

All the best fellow builders.....( I can say that now )

Wow - well done Tony!

You have made an excellent job there, it really looks good and as if it just can't wait to fly. You are a good advert for the kit and Oracover with a well executed and striking colour scheme - I think I want one now!

oooh that's bright, hold on s second whilst I put on my sun glasses smile d ahh that's better. excellent job young man yes it has been an absolute pleasure following you through your build and as Martin says, you are indeed 'a good advert for the kit' and don't worry about the servos being top surface mounted as it will make no difference to the models performance.

I am currently in the process of adding to my website a gallery where modellers can show off their finished models so if you can e-mail me a couple of photos, you can be the first Hammerhead builder to be added to the gallery smile p

for only your second build, you have done yourself proud, I'm looking forward to you fight report,

take care mate

Richie
