Never mind it balanced fine in my fingers, just wouldn't balance in a rack. Just been for a maiden and all I can is WOW this thing is seriously quick, had a good 15 mins before hitting the ground and breaking the nose..... guess the glue is coming back out!

Cheers RC I have done just that all done now, just attempting to set the cog but literally nothing seems to work, moved the battery 0.5mm at a time and it still won't sit flat, it's either tail or nose down everytime. Motor is 53g I belive, could that be the issue?

Yeah I found a few exactlly like that in my box of random bits so will use those cheers Dennis.

Cheers Denis I was testing with a servo tester as no plug in esc yet (my soldering iron turned up today and didn't work) are the push fit horns going to be the best type to use in depron? I just can't seem to find a glue that makes a string enough bond for stick on horns. Have tried por and epoxy and neither seems to adhere to the depron properly

OK all cut out, motor and servos fitted but having trouble with control horns on the elevons, I used a couple of spare mpx horns I had spare with the little adjustable grub screw on them. Fitted all up and the servo seems to push the rod past the horns limit and has pulled it clean off the elevons. Can anyone recommend any control horns that or ways of mounting them that will make them stay on the elevon? I was thinking of getting some of the ones that push through and snap together? Cheers

Sorry Alan only just seen thud after being busy over winter. It's a hobbyzone super cub s. I have recently purchased an 1100kv motor, esc and a few props from a member of my club (also a member on here) going to make a start tomorrow at modifying the battery box to take a 2200mah and when my watt meter arrives this week il run a few tests with the props and see whuch is going to be the best iv got a much better idea of things since I wrote this original post so fingers crossed! How did you mount the motor to retain the original angle? I was thinking of mounting a balsa plate on the original mount and using some spacers to clear the Cowell?

OK brilliant so il build with that set up and the 6x4 and then see how flies and alter the prop set up If needs be will be ordering a watt meter along with the motor and esc

Thanks a lot for your help gents. So iv come to the conclusion of using this motor.... http://www.brchobbies.co.uk/catalog/product_info.php?cPath=103_49&products_id=811 with a 6x4 prop (190watts) And this esc http://www.brchobbies.co.uk/catalog/product_info.php?cPath=15_95&products_id=1309 Would this be suitable for the alpha jet mk2? Should I maybe look at altering prop size slightly to try get those extra few watts or will 10 not make much of a difference? Cheers

Thanks mate the bit that confused me more than anything is knowing what kv motor to use but on most of the plans it states what size prop and kv motor to use, so by taking this info and the models weight I can use the info posted above to work it all out.... I think I'm starting to get it lol. I read about wind loading and surface areas and stuff, does that matter so much if using the watts per pound measurement?

OK cheers il take a look, so presumably I'd need to run it on a 6x4 so I got close to the desired 200 watts?

I'm struggling to find an affordable 2200kv motor so iv found this.... https://hobbyking.com/en_us/d2826-6-2200kv-outrunner-motor.html However it's 342 watts which is well above the 200 you recommended, would this make it too powerful for the model? Also says 5x5 prop recommended for a 3s pack.... This is all so confusing lol

That makes loads more sense than what iv read in the past mate cheers! Il have a look and try find a combination and post here to see what you guys think

I'd still be stuck on the closing of motor and esc though. I prefer the looks of the alpha jet too

It's the whole thing of getting the correct Amps and speed controler that baffles me. I'm usually technically minded but this has confused the hell out of me for a long time, there's just so many motors with the same kv ratings but differ so much with motors and wattage etc
