I have 645mg for steering, stock O.S hot glow plug to start break in, MC8 glow plugs, Byrons 20%. I installed a Traxxas throttle servo because one of the LHS guys told me to do that so that I can use my current fail safe, but didn't work. Which fail safes works with stock 2.4ghz radio system? This is my first OFNA kit, I could use any tips you might have. Thank you in advance.

I broke in the engine, after finishing the break in on the second day I used up my last tank of fuel to bash and jump in grass. I'm very happy with my budget buggy but I'm worried about part support. I have some MC-8's on hand, did I buy the right plugs for my big block? They were recommended by my LHS. I'm not sure how knowledgeable he is, he told me MC-9's are hot plugs. I guess not too many people still run Hyper7's, no replies yet... Here's a pic after break in and my local track I bought this buggy for. I took the exhaust extender off, not sure that it helped, my tire got soaked.

I took my Hyper 7 to my local track about 2 weeks ago, after breaking the wing mount I ended up trashing the rear tower, front gear box, and 3 hinge pins. I got CNC shock towers for front and rear. I got 3/5/1 diff fluids and CNC wheels nuts on the way. I'm going to try 60wt shock fluid in the front and maybe 45 in the rear. I'm not sure if I need the front sway bar or not but I couldn't find one yet. I found one for Hyper 8 will that work? My hyper 7 has 14mm shocks and .28 engine, drop me a line if you know of a good set up. Does OFNA fail safe work with Hobao 2.4ghz radio? Thank you in advance.

Hey gsxr723,

The radio system already has a fail-safe built in. Here is a vid of the system setup:

Radio System

I am not certain what is the proper plug for the Mac28. However, the McCoy plug temps ranges are as follows:

MC-9 Cold
Mc-8 Medium
Mc-59 Hot

Thank you triplebvalp. I was working on my buggy tonight and ran into a problem. I barely got the nut off of the drive cup because of generous amount of thread lock used, now the drive cup is stuck to the pinion and I can't get it off. Does anyone know how I can get them off? I might try to boil the whole thing as last resort. Help me out with some ideas. Thank you in advance.

You should be able to put two screwdrivers under it and pry it off. If that doesn't work then you may have to heat it with a torch ... your boiling idea might work.

BTW, you really need a different picture hosting provider ... the one you use pops up porn in an additional window.

I got the drive cup off by using a soldering gun. I have 60wt so I might try it in the front. On OFNA page there's a Hyper7 pro setup sheet http://ofna.com/pdf/setup-hyper-ryannimori.pdf This will be my starting point except the diff fluid I ordered 3k/5k/1k front to rear. I shortened the turnbuckles by flipping the upper A-arms. I cleaned and serviced the front end and installed the new front gear box and CNC front tower. I'm hoping to find a dry spot somewhere on or off the track and bash around. Man it's been so long since I fired up my new kit. I'm sorry about the pop ups, I'll find a new one soon.

Hey gsxr723,

You never said whether you would be racing or bashing. If you will be racing, I suspect your front shock oil will be a tad heavy. I have never ran a Hyper 7 but I do run a buggy ... Typical fluid setup would be:

50wt Front shock
40wt Rear shock

5k Front diff
5k Center diff
3k Rear diff

The Hitec servo for steering will be fine although that particular servo is kinda slow. Don't know anything about the Traxxas servo.

You didn't mention what receiver battery pack you are using. I would recommend a 5 cell Nimh flat pack.

Oh, and Photobucket is a great place to store your pictures.

Thank you triplebvalp. I'm not planning on racing. I just want to bash around at my local track so I'm looking for durable basher build. The front end sags, I might fill up the front shocks with 60wt tonight since that's what I have on hand. Do I need a front sway bar for jumping? I couldn't find one yet. My throttle servo is a low torque servo I threw in there just to see if it gets the job done, works fine for now. I'm using a stick pack. The weather was perfect today, too bad I didn't get to my local track.

Well, if your just bashing I suppose 60wt up front will be ok ... probably should go with 50wt in the rear. Now, as far as the sag, that is typically associated with something binding such as a hing pin or shock springs to weak, or not enough preloads on the shocks. Shock oil weight will not help or prevent sag.

Again, since your are just bashing, the servo will be fine. The only reason you might want a higher torque servo is to help with the brakes.

I went to the track today, all the snow melted but it was way too muddy. I ended up bashing at a near by parking lot with a section of gravel and bumps. I avoided the baseball diamond and the grass areas even though I made few jumps there because they were still wet. The front shocks has 1 #4 preload, rear has no preloads but still bit higher than parallel and higher than front. With this ride height my buggy didn't want to flip. The hot plug I've been using burned out so I used MC8 medium plugs and it ran fine, idle dropped a bit. I adjusted the shock position on the front tower, made them farther apart at the tower to make putting the body on and off easier. My diff fluids should be arriving soon, that should make some noticeable improvement I hope. I'm very excited about the wheel nuts to, they match my towers and will keep dirt out. I kept my engine temp around 200, I got the engine dialed in and than ran on the rich side just to be safe, not covering the cooling fins and all. It was a comfortable day out today but we got more snow coming this weekend. I used a exhaust extender installed backwards, kept my buggy 100% dry. I should have tried that sooner.

I did some bashing tonight before more snow. My engine temp didn't go over 150 tonight what's the minimum temp? Someone said to set the mid range needle take off the high speed needle and look inside to see if the hole lines up is that correct? Proline V3 wheels my best choice? New pics and a video of my local track with a long triple, I'm not in the video.

I changed out the diff fluids to 3k/5k/1k/ front to back, they were pretty dry. I also put in fresh shock oils, 60wt in the front and 45wt in the rear. The original factory shock oil was clean and had good rebound also. New wing support bolt kit, one more damaged hinge pin replaced. CNC sealed wheel nuts finally came but it doesn't say OFNA on it like the ones I ordered. I cleaned and serviced everything except for the engine, I can't wait to fire it up again.
