Great effort Cliff and the Chipmunk looked great, maybe the rubber is to long, seemed like it never unwound fully and maybe the weight of the extra long rubber impacted the balance? Fun one Cliff, nice that you had an official Flight Timer 😂😂😁😁 Jeff in LA USA
You're correct Jeff in that the rubber is quite long, the oeg length is shortened to help with the cg, lots of rubber can cause challenges but if you get it right a decent flight can happen, whatever though it's good fun 👍
14 seconds is really impressive by my standards! All that rubber motor detail is really challenging. You did get very nice flights in there, lets see if you can reach the 20s!
Hi Morco, there are no rules about the motor but it's already 4x, I've just been informed the closing date is put back another week so there's still hope 🤔👍
My bad, I watched it while I was waiting for good Old RUclips to process my latest video!! It took for ever so my mind wasn't really up to the task Lol
What are you using for weight to change the trim and what were you using for flap on the elevator on the one flight that went almost straight down? New to this and looking to learn. Thank you
Hi Michael, adding weight is not really the correct way to do it. It's better to get the glide sorted first and then slowly add power adjusting the right thrust and down thrust as you go. To answer your question vote it was only Blu-Tack or plasticine as a weight and a piece of masking tape wrapped around the tail end of the model to act as an elevator 🙂👍
Hi Ferdinand, I used to use bent over masking tape but it wasn't brilliant. You can also use plasticine weights on the wing tips or tail. Also you can use Gurney strips, which are just 1/16 lengths of balsa fitted to the trailing Edge on the side you want to cause drag. But on my latest model I've used hinged control surfaces with one of the hinges a piece of copper wire beaten very thinly to hold the control surface in place. The funny thing is about trimming is if it flies brilliant today tomorrow it will have gone out of trim either due to moisture in the air or a small warp creeping in overnight. Another big effect is torque from the motor, as the motor and unwind the torque took becomes less which will also affect the turning circle. Best advice get out there and have fun 🙂 Maxfliart has some decent trimming videos 👍
Thanks, Cliff. Excellent insights. Yes, I was using office file sticky tabs which didnt hold its angle well. When I get better at all other aspects will try hinges so, maybe gurney strips for now. But yes, no matter how imperfect the flights are, it's still a lot of fun. Thanks to you, maxfliart and others, there's a wealth of information to help new folks like me get started!
Cliff, how much right thrust do you have? Have you balanced the model laterally and have you got it gliding straight before trying powered flights? I’m not a fan of adding weight to cure aerodynamic trim issues. I suspect you’d have more success if you put in some more right thrust and perhaps a small gurney strip under the left tip to hold it up in the turn.
Hi Pete, I didn't include the trim glides in this video, no prop etc. I tried adjusting the right thrust quite a bit, adding weight on cg and tip. I agree adding tip weight isn't ideal and it looks horrible, a gurney is a better option. The next two attempts was in a bit of a wind which really makes it difficult to understand what's going on but this was really for the fun of being out in the fresh air, thanks for commenting
@@CliffHarveyRCPlanes, thank you for the update, I’ll say this for your Guillow’s Chipmunk, it’s done infinitely more flying than mine ever did. I built one as a twelve year old and was impatiently tautening the dope in front of a gas fire. One wing caught fire and before I could tear the wing off and save the rest of the model, my mother snatched it from me and ran through the house to the kitchen with it. By the time she got there, there wasn’t anything left of it except the undercarriage wire and a melted canopy. I shudder at my own then incompetence, doping and shrinking a wing after the model was assembled AND trying to accelerate the drying time using heat, it’s no wonder that my models looked like junk back then!
Hi Stephen, the comp is run by Doyle Blevins on the Guillow's Flying Models Facebook Group and a vote is taken during August so at the moment I have no idea, cheers
For a first try it’s a good effort. I wish I could offer some advice, but free flight is not my skill set. I wonder if you have a twist in the starboard wing causing the turns? It’s a pity you don’t have a wind tunnel.😢
True I'm thinking of reinstating the front panels but having access to the interior has been useful for adding replacement wing joiners. Next time I'll make the hatch removable 🙂👍

What a fun thing to do Cliff. A little friendly competition and flying is good for the soul! Nice little bird that one.
And variety is the spice of Life Adam 👍🙂
Nice to see how it improves each time. You'll get it! -Dan
I had my best flight yet yesterday evening Dan, but the light was fading rapidly, I'll try again this morning 👍

Fun video Cliff.
Thanks David, I enjoy these little side projects, they help to keep me grounded 👍

I've had a bit better result this evening but it was getting dark so I'll have another go later this week, cheers.
Well done Cliff
Thanks Stephen 👍
Have you considered using a gurney flap?
I might have to 🙂
Tom Hallman goes for those 4X hook to peg length motors. So, if there are no rules about motor size, this is a way to get your minimum 20 seconds.
Hi Morco, there are no rules about the motor but it's already 4x, I've just been informed the closing date is put back another week so there's still hope 🤔👍
What time were you hoping for Cliff? The plane looked great and surprisingly robust too 😃👍
20 seconds old chap ... and I thought viewers always read the description 😁😁😁👍

New to the hobby and leaning a lot watching your videos. What material do you use for the trim tabs? Thanks!

What is the the plane for the 2024? Do you know were I can find more information about the fly off

Hi Nick, sometimes a warp can help lol, it's just good fun 🙂👍
the windows that you cut out may be causing some trim issues due to drag.
True I'm thinking of reinstating the front panels but having access to the interior has been useful for adding replacement wing joiners. Next time I'll make the hatch removable 🙂👍
@@CliffHarveyRCPlanes Also, you can order a replacement canopy from Guillows if you decide on the conventionla canopy option.
@@MORCOPOLO0817 I actually have a spare Morco but I've stuck clear tape on the front now and it actually looks ok 👍
I am surprised that with just one loop of 3/32 you still needed downtrhust.
It's ine large loop folded in half and braided Morco, essentially two loops 👍
