    IMAC First Carden 124" Extra 300 Pro Build

    Dry run of the initial part of motorbox build while waiting for my Hysol 9462 glue shipment to arrive. Can only commend the quality of the CNC work - each piece fits exactly out of the box. Sent from my Nexus 5X using Tapatalk

    I think it's about time we dusted this project off! As I left things I was going to do the wing cores, but for various reasons, I haven't got the space to work on them. The plan now is to work on the motor box which I do have space to build - I'm going to build it for the DA150/170...

    Prop Choice for IMAC - DA120/RE2 Pipes

    Hi All, For the last two IMAC seasons I've been running a DA120 on JMB TRA-40 canisters, turning a 25x12S Mejzlik 3-blade prop. It's been working great, but... I'm planning to put the engine on RE2 pipes for next season to give me a bit more power. Can anyone recommend a prop for IMAC with...

    Hi @orthobird - afraid not a lot of progress to report. Work and other commitments keeping me busy elsewhere! Hopefully will make some progress over the next few months...

    Great to see you getting back on this Cam. Lost momentum on mine and other hobbies taking up slices of my time... hopefully seeing you make some progress will get me back in the game!!

    A few minor jobs done like cutting the wing tube, marking ailerons etc. but progress has slowed due to my kids being on school holidays now until September. Chances are I won't do much more until they return to school :)

    IMAC First Carden 124" Extra 300 Pro Build

    Both horizontal stabs safely out the bag and pleased with result. Only not to self for future might be to rout a very shallow groove for the unidirectional carbon as you can feel a slight ridge through the skin as you run fingers over it. Not visible and won't affect flight performance, but any...

    IMAC First Carden 124" Extra 300 Pro Build

    Both the cores have been prepared for the horizontal stabs. Got the first stab in the vacuum bag and very pleased with the results. For some reason once the stab is skinned you suddenly realise how big this airframe actually is... Massive thanks for @Terryscustom for his excellent video which...

    Thank you @orthobird! By the time I read your post and being around 8 hours ahead of you on planet Earth I had already plucked up the courage to take this step on. Luckily the approach I came up with was very similar to what you suggested. I also sprayed water mist onto the socket cutouts and...

    IMAC First Carden 124" Extra 300 Pro Build

    I thought that I would do a few tests of gluing sockets and wood rails into foam. I am happy with results of the wood rail, but not very unhappy with the socket - masking tape is welded to the carbon. Certainly not ready to take this step on yet! I need to find a way to protect both the shuck...

    Once the main servo cutout is hot-wired, I have to rout the rails so the servo box can fit flush to the core. The attached photos show my process using a Dremel router attachment + Permagrit fine bit to mark and cut the necessary openings. Overall, am very pleased with the result as the fit is...

    IMAC First Carden 124" Extra 300 Pro Build

    I've been practicing my technique on some scrap foam, ready for making the servo cutouts in the stabs. In the end I opted for a design that uses 1/8" balsa spacers between the rails to ensure the two rails remain parallel during the fitting. The distance between inner faces of rail is 44m which...

    DLE170

    I'm considering purchasing a new DLE170. I'd like to hear anything you like/don't like about this engine please? (I've read the testing data here).

    @jamesrxx951 could you tell me what the mounting bolt centers are for the GP176 please? Can't seem to find that info anywhere on the Internet!
